A welding inverter is a device that has an inverter power source that converts an alternating voltage in the network into current for welding (due to this, electric arc welding is carried out). Inverter welding machines are high-tech units with high efficiency.
This feature not only led to an increase in welding efficiency, but also significantly modified the very design of a transformer-type welding machine: its weight and dimensions were significantly reduced. This made it possible to use the inverter in hard-to-reach places.
The welding inverter has additional functions and settings that can allow you to achieve a very smooth weld. It also has the option of automatic start, regulation of the welding current, which is especially important when welding with thin electrodes. Almost all welding inverters have built-in protection against voltage surges (about 10-20%), which allows you to somewhat secure the machine.
Among the shortcomings, one can single out a slightly higher cost of equipment compared to the previous generation of welding machines, the need for protection from dust, since it can harm microprocessors (it is necessary to clean and blow them more often), low temperature conditions (electronics may not work), as well as the high cost of repairs in in the event of a breakdown due to a strong voltage drop. At the same time, buy a welding inverter today in many specialized companies.
Considering all factors, it is safe to say that the Welding Inverter has an undeniable advantage over traditional transformer machines, especially for novice craftsmen and those for whom the evenness of the weld is important.
