Thermal control on stainless steel: how to vape correctly?

Thermal control in electronic cigarettes

Not long ago, a thermal control function appeared on many modern devices, which immediately gained popularity among vaping enthusiasts.
It is worth saying that thermal control is the direct successor of variwatt, since with its help the power of electronic cigarettes is set, but control of the temperature set by the vaper is a priority.

Moreover, while vaping, the vaper will not even notice the moment when the coil turns off.

Operating principle of thermal control

The operation of temperature control is based on the use of an evaporator made of titanium or nickel, since their resistance increases when heated according to a linear curve. After the new evaporator is installed, the mod board remembers the resistance of the coil in a cold state.

Naturally, to use all the possibilities of temperature control, it is necessary to use atomizers in which coils made of titanium or nickel can be installed. An important detail is the mod itself, with which you can set the temperature from 100 to 600 degrees Fahrenheit (not to be confused with the Celsius temperature).

The temperature is set manually, but in modern devices you can use automatic settings.

Advantages and disadvantages of thermal control

The steam is cooler, tastes better and is just as plentiful. The use of thermal control significantly reduces trothit;
There is no burning taste, since TK (thermal control) does not allow the coil to overheat and prevents the wick from burning;
The temperature of the coil does not depend on the amount of vape liquid and the selected blowing mode. As soon as the liquid level is minimal, the amount of steam will be less or the coil will not heat up;
The service life of the wick and spiral is increased due to the absence of burning;
Battery and fluid consumption is reduced, since the power in such devices is selected in accordance with the temperature;
The liquid acquires a new taste thanks to the choice of the optimal temperature;
Setting up the device is much simpler - you just need to set the temperature in degrees or Joules.

With all its advantages, there are also several disadvantages of using thermal control. First of all, this is a fairly high cost - a mod, an atomizer running on nickel and titanium spirals, all this is quite expensive. There is an opinion that when using nickel spirals, harmful substances are released, but the issue is controversial and unproven.

Some interesting facts about thermal control

Despite the fact that mods with temperature control have been on the domestic market of vape products for several days now, debate about such a function does not subside, giving rise to myths about its use:

With thermal control, you can set any temperature - this is not entirely true, mods make it possible to regulate the temperature within specified limits, but it is possible to block the spiral depending on other factors in order not to damage the mod;
Vaping on thermally controlled mods is dangerous - given the potential danger of nickel, this is partially true. But, as practice shows, when heated, the metal becomes more brittle, which makes its service life shorter;
Before you start working with the TC, you need to burn the mod - you shouldn’t do this, otherwise you can simply ruin the evaporator;
For electronic cigarettes, you can use not only nickel and titanium, but also kanthal, iron and nichrome. Theoretically, it is possible, but when heating kanthal or nichrome there is no linear relationship, so it will not be possible to obtain adequate values;
Temperature control is only available in box mods. Most manufacturers install a thermal control chip in box mods, since their battery capacity is much higher than in cylinder mods.

Naturally, thermally controlled mods have both supporters and opponents, and each of them is right. But in any case, it’s up to the vaper to choose - use new modern technologies, simplifying your life, or give preference to classic mech mods, playing with resistance and metals for winding.

Which is better for vaping, nickel or titanium?

This question arises very often on forums and gives rise to a certain amount of controversy. Titanium shows itself to be the best in terms of characteristics, no doubt about it. If we are considering mods with thermal control, then titanium will provide the best temperature control, which will ultimately give us minimization of battery costs.

In addition to this, titanium has a higher resistance, and it will be much easier to adjust your device to it. According to its physical and chemical characteristics, titanium is the safest metal, unlike nickel.

It is around nickel that the maximum number of disputes and dubious statements are spreading. If we consider nickel as a material for a coil in a device without thermal control, then the danger of nickel vaping does exist. If you read the annotations for nickel windings, you will always find a note stating that such a spiral cannot be burned through during installation.

When the temperature rises above 250 degrees, nickel begins to intensively release toxic substances, which can have a rather unpleasant effect on the human body in general and the respiratory system in particular.

A similar effect can occur when nickel overheats, in devices without thermal control, simply because the liquid in the tank runs out and you didn’t notice it in time. The danger is very real.

As skeptics say, even under normal heating conditions, nickel, although in small quantities, still releases toxins. Moreover, these toxins tend to accumulate in the body, and if they enter the human body for a long time, they can cause serious problems.

The same problem potentially affects devices with temperature control. Although it is impossible to achieve overheating of nickel in this case, small doses of toxins still pose a danger. The risk group for nickel vaping includes people with individual intolerance to it. There are also a number of people in whom nickel fumes can cause various allergic reactions, including swelling of the larynx. And such problems can cause more dangerous consequences of vaping.

What is TK (temperature control)

The TC allows the user to limit the maximum heating temperature of the coil at his discretion and above this set value the coil will not heat up regardless of the set power, the presence of airflow and the presence/absence of liquid.

What are the benefits of using temperature control?

When the coil overheats, thermal decomposition of the components of the liquid occurs with the formation of toxic substances (formaldehyde, acrolein) - popularly called garik. By setting the correct temperature for maximum heating of the coil, you are completely protected from burnt and semi-burnt spots.
There is no need to monitor the amount of liquid remaining in the atomizer and worry that it may suddenly run out. This is very convenient for opaque tanks. When the liquid runs out, the amount of steam simply decreases and you understand that you need to refill the tank.
The organic wick material is protected from burning and your coil or replacement evaporator will last much longer.
When using TC, the taste is purer and develops better. Different flavors reveal the taste better at different temperatures.
You can select the desired temperature and get the taste you like.
Without TC, when the airflow decreases, the steam becomes hard and hot.
When using TK, the taste and temperature of the steam do not depend on the draft force. It’s just that if there is less airflow, you get less steam, but the steam is stable and does not change its properties. For example, you can, without changing the winding, simply reduce the airflow and vape the same device with both a tight cigarette puff and a loose hookah puff.

How does thermal control work?

The operating principle of the TC is the use of special nickel wire (Ni 200, not to be confused with nickel-chrome) (there are also less popular options on titanium and iron). Spirals made of these materials greatly change their resistance when heated.

Before use, the new winding is “calibrated” - the resistance value of the cold spiral is memorized by the board. Then the electronic board constantly monitors the resistance and uses it to calculate the current heating temperature of the coil.

When the set temperature is reached, the board accordingly limits the output power and then maintains the temperature at the set level.

Features of using temperature control

Important : when installing and memorizing the resistance of a new coil with a mod, it must be cold (you can do several idle pulls without pressing a button - blowing will cool the coil if it was heated).

In TK mode, the main and main adjustment is the temperature setting. A correctly operating heating system maintains the set temperature regardless of airflow and even without it at all. When operating a TC, it actually does not matter what power is set as long as the correct temperature is set.

Setting the power in the TC is just a limiter (if you lower the power) or increase it (setting the boost mode) in order to quickly reach the maximum permissible temperature. The actual power will depend only on the performance of the coil/blowing and the temperature setting.

It’s hard to describe, but the taste and sensations from vaping in TC mode and normal mode are different (even at the same power) and strongly depend on the set temperature.

By accurately adjusting the temperature, you can achieve the result you need, incl. get steam as usual.

A big advantage of TK, in addition to its pure taste, is the protection against burns and semi-burns - the liquid runs out and the amount of vapor simply decreases sharply.

Will I be able to vape in TK mode with a tight cigarette puff at my favorite power of 11-12 Watts, if in TK mode the power cannot be set to less than 30 Watts?

- Yes, you definitely can. The actual power will depend only on the performance of the coil/blowing and the set temperature. If you vape on your usual winding and atom (which work optimally at 11-12 Watts), then even though 30 W will be written on the screen, the real power will be 11-12 Watts at the right temperature.

Setting the power to 30 watts will only affect the heating speed of the coil. As soon as it heats up to the desired temperature, the board will immediately reduce the power to the one actually used. By lowering the temperature setting, you can reduce the actual power to at least 1-2 watts. So vaping at low power and cigarette cravings with a properly functioning TC is quite possible.

Will I be able to burn through my spiral?

– In TC mode, you will not be able to heat the coil above the set temperature. You won’t be able to burn in variable watt mode if the resistance is less than 0.15 Ohm. If it is so important for you to constantly burn through the spiral, then use windings with a resistance of 0.15 Ohm or a little more (TC mode supports resistance from 0.05 Ohm to 1 Ohm). We do not recommend burning spirals on nickel.

Will temperature control work if I use nichrome or kanthal (fechral)?

- No, it will not. For proper operation of the TC, materials with a higher temperature coefficient of resistance (TCR) are needed. Nickel, titanium and iron have large TCS. The mod board must be able to work correctly with a specific metal, since their characteristics are different. Now the most common material and supported by all mods with TK is nickel.

All the pros and cons of TK

Thermal control implemented in many models of electronic cigarettes has a number of advantages:

When vaping on the TC, cool steam is produced. This function allows you to select the optimal temperature level to enjoy cool, tasty steam. Many medical professionals have a negative view of e-cigarettes because they produce hot vapor, which can negatively affect the oral cavity. When using temperature control, this problem does not exist.
Forget about overheating and burnt taste! Thanks to the board, the heating temperature is controlled, so burning the cotton is excluded.
Regardless of how much liquid is poured into the tank, and what kind of airflow you use, the temperature control function works correctly.
Thanks to TC, the shelf life of the spiral is noticeably increased. Since burning of the cotton wool is excluded, the maintenance-free coil or winding you have completed will last for the longest possible period.
Temperature control has a positive effect on battery capacity.
With traditional vaping, when the airflow is reduced, the steam may become hotter, but with TK this is excluded - the steam remains tasty and cool.

However, this function also has disadvantages:

The cost of titanium or nickel is higher than the price of other materials;
It is believed that nickel can release harmful substances when heated - this point has no evidence, and to protect yourself, give preference to titanium.

Temperature control

share post with friends

Temperature control appeared in the summer of 2015 and immediately became a hot topic.

This function brought so many useful properties that it instantly became a new standard that e-cigarette manufacturers measure up to.

And thanks to the development of the vaping industry, mods with temperature control immediately began to appear on the “counters”, and there was no need to wait six months for the establishment of production, as was the case with the variwatt.

Variwatt is not mentioned in vain: temperature control in an electronic cigarette is its direct successor, improving the concept of power regulation.

Mods with TK allow you to adjust the power, but when the temperature is set, maintaining it is given higher priority, and if the coil gets very hot, the board gives the command to reset the power in order to cool the evaporator.

For the vaper, the sensations will not change: it will seem to him that the power is still the same. When the coil begins to cool, the board increases the power and, in general, maintains the set temperature in every possible way.

How does thermal control work? The secret lies in the special material of the evaporator - nickel or titanium. These metals tend to increase resistance when heated, and do so linearly and smoothly.

When installing a new evaporator, the mod board remembers what the resistance of the cold coil is, and then, based on the number of Ohms, it can determine how hot the coil is. The use of these particular metals allows electronics to determine temperature very accurately.

Other materials do not have such a direct and clear interaction between heat and resistance, so their use does not make sense.

Accordingly, for the function to work, clearomizers are needed that support the ability to install titanium and nickel heads. As a rule, these are the majority of modern clears: Eleaf GS-TANK TC, Kanger Subtank.

You will also need a mod with temperature control. Here the choice is a little smaller, since the new product is not yet so widely represented in the model ranges of large companies. Examples include eVic VT, iStick 40W TC, Sigelei 150W TC, Kanger Nebox. The difference between these mods is a special board that “understands” the resistance indicators of nickel and titanium.

Temperature control allows you to adjust the temperature between 200-600°F or 100-315°C. Accordingly, the unit of measurement during adjustment becomes not Watts, but degrees. In some mods, there is a switch to Joules, which determine the heating rate of the coil. They can be set manually, or you can trust the automation, which “knows better” and will select the optimal value.

The benefits of temperature control are quite impressive:

cooler steam - by setting the temperature, you can limit the “waste” heating of the coil, which will make the steam cooler and more pleasant to taste, without losing its abundance. An important feature of cool steam is that it does not irritate the mucous membrane of the throat. According to WHO doctors, hot steam was one of the last complaints against e-smoking, as it could provoke diseases of the oral cavity. With TC, electronic cigarettes become even safer for health;
no burning aftertaste - the book saga about Harry Potter is over, and so are his adventures in vaping. The mod board monitors the heating of the coil and promptly reduces the power when overheating, thereby eliminating the possibility of scorching the wick. In addition to the unpleasant taste, “garik” also emits harmful substances, so its absence will have a positive effect on the health of the vaper;
the heating temperature of the coil does not depend on the amount of liquid and airflow - on any clearomizer with support for nickel or titanium evaporators, temperature control will perform its functions equally well. When the liquid begins to run out, instead of burning, there will simply be less steam, or the coil simply will not heat up;
the wick, and with it the coil, will last longer - the evaporator, protected from burning, will need to be changed less often;
battery and liquid consumption is reduced - unlike conventional mods, an e-cigarette with a TK does not always “fry to the fullest”, but reduces power when it is not required. As a result, less energy is consumed and less “slurry” is evaporated in vain;
the taste of the liquid is better revealed - with a simple selection of temperature, you can rediscover the familiar mixture;
setup is simplified - you can forget about Watts, Ohms and Volts, just set a comfortable value in Fahrenheit or Celsius, or in Joules;
the taste and saturation of the steam do not depend on the airflow - mods without thermal control make the steam harsh and hot when the airflow is reduced. Temperature control at any draft leaves the steam cool and tasty. If you reduce the airflow, there will simply be less steam, nothing else will change.

Are there any disadvantages to temperature control? Yes:

high cost - the mod itself, a clearomizer with support for titanium and nickel, evaporators made of these materials add up to a significant amount. True, not all devices are expensive: the Eleaf iStick 40W TC costs the same as a regular mod without thermal control, while its colleagues are about twice or even three times more expensive, like the new late 2015 Kanger Nebox;
the danger of releasing harmful substances when using nickel is still a rather controversial issue, but it would be criminal to remain silent about it. Those who want to neutralize even a potential threat should use titanium vaporizers, which are even more expensive.

New products always give rise to rumors and myths, let's figure out which of them is true and which is not:

TK allows you to select any temperature - this is not entirely true, mods with thermal control allow you to adjust the temperature within the range of 200–600 °F and 100–315 °C. But depending on other settings, the board may lock the device at certain temperatures to prevent damage to the mod. There is also a slight error that varies depending on the device. Because of it, the set 200 °C may in fact turn out to be 210 °C or 190 °C;
Temperature controlled vaping is hazardous to health - partly true when you consider the potential dangers of nickel. When heated above a certain threshold, this metal becomes toxic and brittle, which not only harms health, but also shortens its service life. The effects of nickel in TK mods have not yet been studied, and those concerned about it should use completely safe titanium;
The evaporator for the TC must be burned before use - under no circumstances should this be done! Taking into account the above point about nickel, this will not only damage the evaporator, but also put your health at risk. Moreover, the mod with TK will not allow you to burn through the spiral, since this is not required;
The power on the screen has nothing to do with the real thing - true. However, it is worth considering that despite the discrepancy “on paper”, “in sensations” it will seem to the vaper that the e-cigarette is working at the set power. Actual values depend on the performance of the coil and the quality of the airflow, as well as the set temperature. By adjusting the number of degrees, you can achieve the desired sensations corresponding to your “favorite” power;
you cannot set the power below 30 watts on cigarettes with TK - a myth that is a continuation of the previous point. Depending on the airflow, temperature and heating of the coil, the mod can reduce the voltage below 30 Watts so as not to overheat the evaporator. Moreover, there are mods that allow you to set single-digit power values in vari-watt mode, and it can be used in TC mode;
you can wind a spiral for TC from nichrome, kanthal and iron - partly a myth, partly true. Due to the special properties of nickel and titanium, the board can accurately monitor temperature based on their resistance; nichrome and kanthal do not have this. Iron has similar properties, but the relationship between heating and resistance is not so linear; moreover, a device with thermal control must “know” metal, but modern products do not perceive “stainless steel”. However, vapers have learned to trick their mods by presenting the iron coil as low purity nickel (10-11% for the Nebula SXK60 e-cigarette). At these settings, “stainless steel” works with temperature control, but these are still amateur experiments. In the future, perhaps iron will become an alternative material for fuel cells, thus reducing the cost of evaporators;
TK is only available in box mods - more likely yes than no. All major manufacturers have chosen the box mod form factor for temperature control, as have the smaller ones. However, you cannot ignore cylinder mods with TC like the Heatvape Power Tube TC. So far, only Heatvape has appeared in an unusual form factor for thermal control.

The iJOY Asolo 200W TC mod deserves a special place in the myths section, which was declared as the first and only e-cigarette with TC on kanthal and any material in general.

At first, the data was even confirmed, but when it went on general sale, it turned out that you still can’t fool physics, and on the kanthal TC from iJOY Asolo 200W TC did not work at full capacity, but was simply a kind of protection against “flares.”

With the new version of the mod, the manufacturer put a good face on a bad game and stated that “TC” in the name is an abbreviation not for “Temperature Control”, but for “Taste Control”, that is, the same protection against the burnt taste.

In addition, independent vapers conducted a series of tests and proved that the mod does not even produce the promised 200 Watts, being limited to approximately 166 Watts. By the way, the price of this e-cigarette is 70–100 dollars.

In conclusion, we can cite popular box mods with temperature control from trusted manufacturers.

Joyetech eVic VT is a stylish and productive mod that claims to be the first device with TK. The maximum power is 60 Watts, and the battery capacity is 5000 mAh.

Sigelei TC 150W is a large mod with a maximum power of 150 Watts and two replaceable 18650 batteries. Combines variwatt, varivolt and temperature control. But for such functionality you will have to pay double the price.

Eleaf iStick TC 40W - 2600 mAh and a “ceiling” of 40 watts. However, despite its functionality, the device is very affordable. In this regard, the comparison of Eleaf iStick TC 40W and eVic VT is very indicative

Cloupor GT 80W - like Sigelei, combines variwatt, varivolt and temperature control. The device has a maximum power of 80 watts and two removable 18650 batteries.

What is thermal control on electronic cigarettes and why is it needed?

Thermal control will show itself in practice only with those materials that have a high resistance coefficient. It is the dependence of the resistance on the heating of the winding that is the fundamental characteristic for temperature control.

Let's consider the most popular winding materials for TC.

Nickel

The first company to collaborate with this material was Evolv. Nickel has the highest resistance compared to other materials and alloys that are used to wind coils in the vape industry.

Titanium is slightly inferior to nickel in terms of resistance coefficient. This material is most often found in sump tanks.

Despite the fact that titanium is inferior to nickel in terms of TCR, TC on titanium has a number of advantages:

there is the possibility of producing microcoils;
can be combined in windings with other materials;
has higher strength than nickel;
safer to use and not subject to oxidation and corrosion.

Of course, it is worth noting that titanium is significantly expensive, so if you are just learning how to wind coils, it may be worth considering cheaper materials.

Stainless steel

The TCR of this material is the lowest among its peers. Based on this, this material is chosen least often for winding coils. But one cannot help but notice that vaping on a stainless steel coil has one distinctive and interesting advantage.

When using nickel in temperature control mode, by pressing the power button, the coil heats up instantly. This will ensure that the taste of the liquid for vaping in an electronic cigarette will be revealed from the first second of vaping and it will be as effective as possible.

Stainless steel has some nuances when used in temperature-controlled devices. As mentioned earlier, the first attempts by folk craftsmen to attach nickel to the TC were from the eVic VT device. 321 grades of stainless steel were used.

In order for your thermal control device eVik VT to be able to work with this material, which in theory it should not work with, you need to configure your device correctly. To work with this device, we will use 304, 316 and 321 stainless steel. 321 stainless steel is not generally accepted. This alloy differs from 316 only in the absence of molybdenum. molybdenum

It is worth noting that stainless steel coil wire should not be coated with brass or nickel. There is an expert opinion from folk craftsmen that if your wire is of high quality and not homemade, then simply winding it and turning on the device in TK mode, it will work on its own.

This can happen if you use simple architecture windings. If this did not happen with simple winding, or you used a pigtail, or more tricky coils, then the first method will help you.

What is the difference: variwatt, varivolt?

Gone are the days when you could buy an electronic cigarette, fill it with e-liquid and not think about anything. Modern steam generators, of which there are many brands and models on the market, try to surprise their users with a maximum of various functions, options and bells and whistles.

Some are very useful, others are dubious. And if for some, an electronic cigarette is a mechanical mod, then for others, thermal control has already become an integral part of vaping.

Variwatt also has a similar chip, the only significant difference is that Variwatt independently maintains a certain power on the coil, regardless of the resistance of the evaporator.

This can already be called an automatic type device. Some electronic cigarettes can remember certain operating modes and when you connect a new coil to the circuit, you will not need to waste time reconfiguring the system.

The parameters will be adjusted within a certain range set by the model manufacturer. If the device is designed for 40 watts, then you will not be able to get 50 from it. Therefore, when buying a device, you should inquire in advance about its operating range.

Essentially, both devices have the same function. They change the output voltage that will be supplied to the atomizer. Variwatt uses automation, which allows you not to think about the resistance currently used and get maximum pleasure from the vaping process.

Method one

As soon as you have made your winding and have just secured it on the base, even before you tried to burn it or perform any other actions, you need to allow the device to remember the current resistance of your winding.

Further, during the burning process with inserted cotton wool and filled with liquid, the resistance will rise by a couple of hundredths of an ohm. And this expansion will give us a 95 percent guarantee that your thermal control will work.

The second way to make friends with stainless steel wire is the most banal way - just wait. You need to drive such a winding in the mode of 35, 40, maximum 44 watts. After which you switch to titanium mode, and “lo and behold”!

You are no longer thrown out of thermal control mode. So, as it turns out, vaping a stainless steel coil on a device that is not ready to work with stainless steel is not such a magical thing.

Temperature control

In devices of the previous generation, when the power increased to a critical level, the temperature of the coil increased proportionately, and the slightest negative impression from such vaping could result in a burning sensation in the mouth. Although there could have been more unfortunate consequences.

Let's figure out how this thermal control works:

The material for the spiral can be nickel, titanium or stainless steel. When installing a coil made of the appropriate material, the board records the temperature characteristics of the coil in a cooled state, and as the coil heats up, it calculates the resistance and determines the difference in temperature readings.
Thermal control regulates the temperature ranging from 100 to 315 degrees Celsius. Resistance of a heat-resistant alloy of iron and chromium when heated. It does not change, which means it does not have any effect on the power that will be supplied to the spiral. If temperature control is used, then it is necessary to use materials that will change their resistance when heated. This is why temperature control is not possible on kanthal.

However, in the latest generation devices, such as eVic VTC mini, when installing firmware version 3.0, in TCR mode it becomes possible to use canthal, and many other metals that were not previously supported.

A lot of devices that have vari-watt and vari-volt functions have such an interesting option as thermal control.

As the name suggests, thermal control is a mode in which the control chip will maintain a certain heating temperature of the coil, with dynamically changing secondary parameters in the electrical circuit. Why is temperature control needed?

To begin with, it’s worth saying that this mode allows you to prevent the coils from overheating. Well, overheated and overheated, novice vapers will think and they will not be very right.

An overheated coil can cause several things:

the trouble of spiral failure;
fragility of the device;
some harmful substances that can enter your body.

The very fact of the presence of metal microparticles in the lungs is no longer a very pleasant fact, and if you consider that such vapors of some metals are quite harmful to the body and can accumulate in the human body for years, then it is worth considering whether thermal control in electronic cigarettes is important or not.

Thermal control greatly simplifies the vaping process for the vaper and provides a comfortable and worry-free vaping experience. You can set the temperature range yourself, not only for safety reasons, but also based on the preferences of the device user.

It is worth drawing your attention to the fact that variwatt, varivolt mode and temperature control mode are all functions for advanced users of electronic cigarettes.

When working with such devices, it is very important to familiarize yourself with all the nuances that can await you during the work process, and it is advisable to know the operating principles of the main operating modes of the electronic cigarette. Working with such a device without knowledge and skills can be dangerous, just like working with a mechanical mod.

There is no burning or dry steam. We get garic because we forget to put in the liquid. But with the thermal control mode, this should not happen. The fact is that when the liquid runs out, soaring on dry cotton wool begins.

The temperature begins to rise sharply. But this regime does not allow her to do this. And as a result, you just start to get less steam and this will make you remember the liquid.

Thanks to this, you don’t catch garika even on dry cotton wool.

We heat the liquid to the temperature we need for vaping. Avoiding overheating. And changes in the chemical composition of the liquid. That is, we soar only because it is safe.

Mech mods

The mechanical mod is fundamentally different from the devices described above. A mechmod is an electronic cigarette that is completely devoid of any electronics.

This mod consists of a battery, an atomizer and a button, which mechanically closes the contacts and supplies voltage to the evaporator. This electronic cigarette does not provide any settings.

The maximum power of the device will depend only on the battery charge level.

Externally, mech mods look like an ordinary pipe, only a little prettier. Inside this pipe there is a battery and, mainly, in the lower part of the body of the mechanical mod there will be a button that closes the contacts of the electrical circuit of the device. There are mechanical mod options that allow you to install multiple batteries.

There are absolutely no variations in technical characteristics in these devices. The batteries that are installed in such devices are almost always standard, and based on this, manufacturers organize races among themselves to cool the design of the appearance of the devices. And on the market you can see a simply endless number of varieties of mechanical mods.

They all have their pros and cons.

The advantages of mechanical mod include:

In theory, mech mods are very easy to use. Compared to variwatt, varivolt, temperature control devices, there are basically no non-constructions in the mechanical mode.
High reliability, which is due to the maximum simplicity of the design.
Devices without control chips and at a price much lower than high-tech electronic cigarettes with screens.
A huge selection of device appearances will allow you to get an electronic cigarette to match every tie or sneakers in your collection.
There are no restrictions. Any coil that you install will simply work, if you calculate everything correctly, of course.

And this is where the second side of the mechanical mod coin begins – its shortcomings.

The disadvantages of the mechanical mod include:

As noted above, the simplicity of this device is only superficial. In practice, the situation is much more serious. The lack of electronics is both a plus on the one hand and a minus on the other. Without electronics, you will have no protection from over-discharging the battery, from overcharging the battery, or from a short circuit in the electrical circuit of the device. This suggests that the use of this device requires a high level of theoretical and practical knowledge and great care. With the slightest violation of safety rules, or with an incorrect calculation of the electrical circuit, you can get an explosion of serious force right in your face, which can cause colossal injuries.
There are a lot of cheap and low-quality products on the market, therefore, based on the first point of disadvantages, do not chase cheapness. A 6 year old girl should not carry a time bomb made in China in her pocket.
The basic package of mech mods does not include a battery and charger, which means additional costs for you.

From all of the above, we can conclude that a mechanical mod is not a toy for schoolchildren.

Stainless steel VS iStick TC 40

We will install a stainless steel subtank on our device with thermal control. Titanium mode with a temperature of 200 degrees Fahrenheit.

This device works with stainless steel absolutely calmly, and there is no need to dance with a tambourine around the device, the only thing you need to pay attention to is that from the first second of vaping, all 40 watts of the device are supplied to the coil at once, and only then the power starts be regulated.

Such problems can only appear in devices that are not the latest generation. The most modern roofing felt devices already support a great variety of materials in the basic configuration, or by improving the software, they acquire these options already during operation.

But in any case, craftsmen do not sleep, and if your favorite electronic cigarette does not yet know how to use stainless steel, be patient. Soon the masters of the people will come up with life-saving ways for you to steam stainless steel using thermal control.

Conclusion

Variwatt mode will allow you to adjust the power of your device, varivolt mode will allow you to control the voltage, thermal control mode will give you the opportunity to maintain a certain heating temperature of the coil. All this is very convenient and gives a very large scope for the vaper with a guarantee of the highest level of safety of the vaping process.

Thermal control. What are you and why?

Thermal control is a word that has recently caused a real stir around itself, as a revolutionary breakthrough in the world of electronic cigarettes. And this is not at all surprising. This technology has brought vaping to a sky-high level of comfort and safety. However, on the one hand, the hype is gaining momentum regarding the coolness of the device, and on the other, regarding its price. But more on that a little later. What is all this thermal control all about?

You can talk about this in detail for a very, very long time. We will look at the basic principles and conceptual differences between new devices with thermal control and electronic cigarettes of the previous generation. If we try to describe the principle of operation of this indicator in one sentence, then temperature control works by using resistance when heating certain metals.

Different metals have their own resistance.

Inside each electronic cigarette there is a metal coil that evaporates the vaping liquid and turns it into vapor. The technical parameter of this spiral is its resistance. If you have a device with a display, the resistance will be displayed on the device's display.

There are some standards in the manufacture of electronic cigarettes. According to this standard, most evaporators and windings are made of kanthal. The resistance of this material does not change when heated, or simply does not “jump”, which does not affect the change in the power that needs to be supplied to the coil to heat it.

Thermal control will use a material whose resistance will change as the heating temperature of these materials changes. The board inside the device has the functionality to calculate the power supplied to the spiral using a certain formula.

It works as follows: the mod remembers the initial value of the coil resistance and then, when the temperature changes and the resistance changes, calculating the power using the formula, it maintains the heating temperature at a certain level. For example, if initially the resistance was 20 Ohms, and then changed to 40 Ohms, this means that the temperature is approximately 200 degrees Celsius.

Each mod with temperature control allows you to control not only the power, but also the heating temperature of the coil. This allows the user to set the desired level of heating of the coil, and the mod will automatically calculate the required power supplied.
