foxweld master 202 reviews

Having read the experience of people who have used this device, they recommend it as a good long-lasting inverter. But nevertheless, there are also disadvantages: a short cable that becomes dull at low temperatures and bursts, an inconvenient holder. The device could withstand operation at -25 °C. Workers prefer this device to Resante, as it works better and is softer. Master 202 is one of the most popular inverters in Russia. In the first days of operation, users are satisfied with the performance of the device, characterizing it as a fairly high-quality Chinese product that is worth the money. Works well with three and four millimeter electrodes. Some people complain about the short arc of the device, but this can be attributed to the inexperience of users. Typically, workers use the device for years and it serves them well in their summer cottages and in the development of small businesses. The Foxweld 202 inverter belongs to the Italian Foxweld, but all parts and equipment are assembled in China, undergoing three-stage testing. In Russia, the equipment has all the necessary certificates.

Everything is okay. Then we put everything back together as it was. There are 12 transistors, everything needs to be wiped clean of old dried paste, as well as the rubber gasket. Then apply new grease and put everything in place, the board should fit into the four guides there are plastic heels 4 pcs. Then we fasten all 12 transistors on one side with staples. And we check with a tester whether the central terminals of the transistors are touching the housing; sometimes the gasket breaks and the transistor touches the housing and can fail and pull the entire arm along with it. And you will also have to repair the inverter itself, which means extra problems, money and time.

Repair of welding inverter FoXWeld Master 202 photo board

According to this scheme, there are many brands of welding machines: BRIMA and Sai 200 and Iskra , etc. I have encountered many defects in these models; most often one transistor breaks down and when the device is turned on, it immediately goes into protection. The same thing happens and a diode breaks through, it also goes into protection. But these devices are very reliable and have proven themselves very well in production.

Device description: FoxWeld Master 202 front panel

Front panel with display and switch off switch

• Reliability of equipment, possibility of autonomous use;
• slight metal spattering;
• forced cooling system;
• there is an anti-stick function for the electrode so that it does not stick to the base metal;
• there is a “Hot Start” option for quickly obtaining an arc;
• “ARC FORCE” function for stable arc burning;
• resistance to high humidity;

On the front side of the device there is a special a yellow lamp that lights up when the voltage in the network changes; if the protection is triggered, the device will be turned off for a while.

Specifications:

Idle speed is 59 volts, welding current is adjustable over wide intervals (from 20 to 200 amperes).

To operate, you need a mains voltage of 210-255V, minimum value 180V. This device received excellent arc ignition, a good appearance of the weld, a uniform droplet shape, and good current characteristics. This is achieved thanks to the operation of power modules at a purity of more than 80 kilohertz, where the response value does not exceed 500 milliseconds. Without emergency on. Foxweld Master 202 at the maximum welding current (200 amperes) is 60%.

Technical parameters of Kempi

Technical characteristics of Kempi Master 202

The Master 202 welding inverter has many useful functions that ensure its comfortable use. This device is equipped with a “hot start” option, has excellent current-voltage characteristics, and there is the possibility of stabilization and automated control of the electric arc. Thanks to its optimal design, Kempi welding is able to work efficiently with minimal spattering of molten metal, even in the presence of difficult environmental factors.

The development of the device ensures the highest degree of safety, which is explained by the requirements of working with high voltages and temperatures. Therefore, the Kempi body is made of high-strength plastic, which protects well from contact with the main power elements. The design of the control knobs and buttons prevents accidental activation due to impact.

The welding machine is protected from dust, dirt, water and high humidity. The main control elements of Master 202 are located in a hermetically sealed compartment where foreign objects cannot enter.

Master Problems 202

If you notice any changes in the operation of the device, for example, the light does not light up, you should stop working immediately.

• if the circuit breaker fuse is turned off, the automatic plugs on the electrical panel should be replaced with a value of 25-35 amperes;
• if the foxweld master 202 inverter begins to emit a burning smell, it should be turned off immediately and taken for repair;
• if your electrode often sticks, you should increase the current;
• If the arc does not light up, but the fan and green signal are working, you should check the welding current regulator (position OA).

You should beware of various fakes foxweld master 202

since this can lead to bad consequences. Always use original equipment, not counterfeits. This will save you money and health

Possible malfunctions of the device and ways to eliminate them

A situation may arise when the power indicator does not light up when the device is turned on and the fan is running. This may indicate a failure of the circuit elements, which requires contacting a service center. Situations where electric shocks are felt while working on the inverter can be resolved by checking the contacts of the power plug, the quality of the connection of the grounding and power cables. Other common malfunctions in the operation of the Foxweld inverter of the model in question include the following.

• The network machine is turned off. In this case, you should replace it with a more powerful one (25 or 32 A).
• The smell of burning coming from the device and its smoke require contacting a service center.
• If the welding arc does not ignite when the power indicator is on and the fan is running, you should check the position of the current regulator. It may be at position "0".
• When the yellow indicator on the device panel lights up, this means that automatic surge protection is turned on. You should wait until the network parameters return to normal.

If you purchased an original Foxweld inverter model Master 202, and not a fake, you will certainly be satisfied with its technical capabilities, reliability, ease of operation and maintenance.
