Technologies requiring the use of welding machines are quite diverse, and with the development of these inverter-type devices, which:
- Easy to maintain and use.
- Small in size.
- Designed to operate on a household electrical network.
- Inexpensive and affordable.
They began to be used as the so-called "garage-household" equipment for personal needs. But, like any equipment, they require regular maintenance (you can sign up for a preventive repair of welding machines in Samara in online format using the website of the company that provides this type of service). Why it is not worth carrying out repair work on our own, we will analyze in more detail.
Features of the repair of inverter welding machines
It's no secret that welding works are carried out in conditions of high dust content, which settles not only on the body of the device, but also on the internal parts. Another detrimental factor for them is their use at negative temperature values, which leads to the formation of condensation. As a result, the following defects may appear:
- Instability of the welding arc during operation - may occur if the current strength is incorrectly set when using electrodes of different diameters.
- High consumption of electrical energy in the on position, even without load - occurs when the turn-to-turn short circuit of the transformer winding.
- Protection against overheating of the device is triggered - incorrect operating modes or high concentration of dust on the parts and assemblies of the device.
- Unable to adjust the welding current - controller malfunction or lack of quality contact.
Due to the fact that the inverter welding machine is equipped with an electronic control device, its diagnostics and repair are possible only with the use of special test equipment. As a rule, the listed malfunctions are successfully eliminated (repaired) due to the high professional experience and skills of the repair service specialists.
