How to work with the Svarog inverter device?

The durability and reliability of the inverter depends on its proper operation. The device is installed in such a way that it is provided with sufficient air flow for ventilation, and is not exposed to dust, dirt, metal sparks, or exposed to an aggressive environment.

When connecting the Svarog ARC 205 inverter to the network, you should check its compliance with the characteristics given on the plate attached to the case. The circuit breaker and socket must match the power of the standard plug of the device. When working at contact points there should be no sparking or overheating. The device can be used for argon welding.

When manual arc welding, MMA mode is selected using a switch on the panel.

The forward and return cables are tightly inserted into the panel connectors “+” and “-”. Then the tips are turned clockwise all the way. When welding with straight polarity, the electric holder is connected to the “-” connector, and the return line is connected to “+”.

Excessively long welding cables should be avoided. To prevent a large voltage drop across them, long wires should be taken with an increased cross-section.

The welding current is set by the control knob of the same name. It must match the diameter of the electrode.

Under normal operating conditions, special maintenance of the welding inverter is not required. Particular attention is paid to the reliability of connector fastening and the absence of damage to power cables, housing and controls.

Welding with the Svarog ARC 205 inverter is carried out with direct current (DC) using inverter technology. The device is powered from a conventional single-phase network 220 V, 50 Hz. In the absence of a stationary power source, it is possible to connect to a gasoline or diesel generator that provides voltage in the range of 185 V–260 V.

The AC supply voltage is converted into DC by the mains rectifier and inductor. The resulting direct current is supplied to the IGBT block of power bipolar transistors. It inverts direct current into RF alternating current with a frequency of 20–50 kHz. The step-down transformer reduces the voltage to the operating level, after which it is rectified again and supplied to the operating connectors located on the front panel of the case.

Such preliminary conversion to high-frequency current allows the use of a transformer with very small dimensions. Compared to “classic” welding machines, the inverter weighs several times less, has better technical characteristics and efficiency.

The high quality of the welding process is ensured by a control unit with digital signal conversion (DSP).

Characteristics of the welding inverter Svarog Arc 205

The welding inverter Svarog Arc 205b has become popular among users due to its characteristics. It can operate in almost all required ranges that are needed in the private sector and repair shops. When choosing, people first pay attention to the characteristics. You need to know what maximum current the device can produce, what thickness of electrodes it can work with, what time of continuous operation it can provide, and so on. For each application, the most important parameters come to the fore. Here you can find out what characteristics this model has and decide how suitable it is for your purposes.

The set includes a holder for a welding machine, a cable, a tip, a grounding terminal, and a power cable for connecting to the network.

Operating instructions for welding inverter Svarog Pro Arc 205 J96

The first priority is to prepare the workplace, as you need to ensure good ventilation so that nothing interferes with the penetration of air into the cooler. It is best if there is additional natural ventilation, as when working in an open area. If the ventilation is weak, the PV level may decrease significantly, which will lead to overheating and possible breakdowns.

Particular attention should be paid to input parameters from the network, since jumps or large discrepancies with the nominal value are often observed. You should measure everything before turning it on, so as not to expose the equipment to unnecessary risks. You also need to check the reliability of the wire connections, since loose terminals can lead to breakdowns, overheating and other negative phenomena.

Modes

For each metal thickness, you need to select your own diameter of the consumable. This is required so that the seam can be welded to the proper depth. To ensure welding, a certain temperature is required. It is set by the current value, but it must be selected quite accurately, since if you exceed the optimal value too much, the workpiece will burn out, and if you make it lower, the electrode will stick. Here are the main modes for a certain type of part thickness:

Key features of the device

• the presence of the Hot Start function (hot start) when igniting the electric arc;
• equipped with Antistick anti-stick option;
• adjusting the arc force (increasing power) guarantees deep penetration and a flat, even seam even at low current;
• 80% load duration when operating at a maximum current of 180 A;
• the ability to connect to a container with argon with subsequent welding of “non-ferrous metal” with non-consumable electrodes using the TIG method;
• equipped with a fan, protection against overheating and overvoltage of a single-phase 220 V network;
• the presence of a switchable idle voltage reduction system VRD.

Advantages and disadvantages of the ARC 205 model

The inverter has the following advantages:

• the weld seam, subject to the minimum rules, is laid evenly and is always deeply welded;
• Electrodes with any type of coating can be used as consumables;
• possibility of connecting a TIG torch for welding in argon;
• presence of forced cooling with a built-in fan.

The disadvantages of this model include:

• lack of push-button activation/disabling of the “hot start” and “anti-stick” functions (automatic only);
• activation of the overheating protection system, which turns off the device for a few minutes during continuous hours of operation;
• The inverter shell does not protect against dust, dirt particles and side drops of rain from entering the device, in this it is inferior to models from other manufacturers presented on the Russian market.

Advantages and disadvantages

Like many inverters, the Svarog line has the following advantages:

• due to the ease of ignition and a stable arc that self-regulates, even a beginner can easily master the welding process;
• little splashes are formed and the metal is well boiled;
• high efficiency – 85%;
• a small open-circuit voltage when the inverter is not working is only 9-15 V with recovery to 65 V when the electrode touches the surface;
• The device is protected from overheating, and the circuit also compensates for differences in mains voltage.

Among the disadvantages, susceptibility to moisture should be noted. It is better not to weld in the rain, or the machine should be reliably protected from splashes. The presence of dust inside inverters adversely affects their performance. Contamination from cutting or grinding metal has a particularly negative impact. The devices should be periodically cleaned by blowing with compressed air to prevent the accumulation of dust inside.

Customer Reviews

According to customer reviews, the ARC 205 welding inverter model can be considered one of the best in its class. With its help, you can perform work of varying complexity and volume. However, for confident welding with “five” electrodes, the maximum current of 180 A is not enough.

The model is equipped with a handle (and not just a strap) for carrying, which creates additional convenience for users. The display quite accurately reflects the actual current of the inverter; the spread of the parameter is ±3–4 Amperes. According to users, the peculiarity of this device is that it does not overheat and operates stably at ambient temperatures up to +40ºС. The use of toggle switches on the front panel in real operating conditions is more justified than “pressable” pseudo-sensors.

conclusions

The Svarog ARC 205 inverter is suitable for welders with any experience, including novice welders. The product item is popular with buyers and has been a trending product in the domestic welding equipment market since its introduction. The selling price of the installation in most cases is lower than the cost of many foreign models with similar characteristics. The Svarog ARC 205 will meet the expectations of those users who need a welding machine with a reputation as a trouble-free “workhorse” at an affordable price.

Frequent malfunctions and their elimination

The welding inverter “Svarog ARC 205” is characterized by problems inherent in all similar models.

1. Protection shutdown due to overheating. The reason may be dust on the device. The inverter should be cleaned periodically or selectively by blowing with compressed air. Dust accumulates with constant use on open construction sites. If the thermal relay fails, it triggers falsely, although the device does not overheat. The part should be replaced by a service center. There may be bad contacts at the connection points that need to be tightened.
2. Constant sticking of the electrode and poor quality of the arc with a working device occur when the voltage in the network drops below normal or when weak power wires are used.
3. The burnout of the device with the smell of burning insulation occurs as a result of a short circuit. Repairs are carried out in specialized workshops. Burnt out wires can be replaced yourself.

Annual maintenance of the device at the service center allows you to operate it significantly longer than the warranty period of 5 years. It may differ from one manufacturer to another and may not exceed 2 years, although this is not too short.
