How to choose a welding inverter?

When choosing a welding inverter, you should consider its main technical parameters, as well as the presence of additional options.

Rated welding current. In the home it will be enough for 160-200 A.
Type of welding. This can be manual arc welding, semi-automatic, argon arc and some other types of welding. They differ in principle of operation and quality of welding, the type of material used for welding, as well as requirements for the skills of the welder, so it is worth consulting with the seller here.
Mains voltage. The data sheet will indicate whether the device works only with a stable single-phase network (deviation not more than 15% of the norm) or with unstable, too. For use in a big city, where the mains voltage is stable, models from the first group are suitable, but in villages, cottages and in the countryside, devices suitable for unstable voltage should be used. Only devices from this group are acceptable for use when supplied by a generator.
No-load voltage. The closer to the upper limit (90 V), the better. The optimal range is 40-90 V.
Mode of operation at maximum current. The value is expressed as a percentage and defines the ratio of the duration of continuous welding operation to the total operating time of the device. That is, if the indicator is 60%, it means that you can weld for 6 minutes, and 4 minutes the unit should rest. The optimal value is 50-60%, a good value is from 70%.
Current control method. It is better if the current is regulated smoothly.
Additional functions such as hot start, arc afterburner, and anti-stick.. The most useful functions are hot start and auto shutoff. The first provides a faster start, and the second avoids the consequences of long continuous operation of the switched on machine.

Which is better - inverter or transformer?

Each type of welding machines has its own pros and cons. Devices of the inverter type are smaller in size, more economical in terms of power consumption, equipped with more functions.

At the same time, they are more expensive, more sensitive to operating conditions, more difficult to repair, incapable of continuous operation for a long time.

However, transformer welders are only suitable for industrial applications: they require a lot of space for installation, and their operation is possible with certain skills. Therefore, it is preferable to use inverters at home.

Conclusion

When choosing an inverter welding machine, it is worth considering, first of all, the voltage tolerance of the device, power, compatibility with different types of metals and functionality.

For domestic use, inexpensive and reliable devices from the well-known manufacturers presented above are suitable.
