How to choose a welding inverter?

When choosing a welding inverter, you should take into account its main technical parameters, as well as the availability of additional options..

Rated welding current. In everyday life, 160-200 A will be enough.
Weld type. It can be manual arc welding, semi-automatic, argon-arc and some other types of welding. They differ in the principle of operation and quality of welding, the type of material used for welding, as well as the 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 no more than 15% from the norm) or unstable too. For use in a big city, where the mains voltage is stable, models from the first group are suitable, but in villages, in summer cottages and in nature, devices suitable for unstable voltage should be used. Only devices from this group are allowed to be used when supplying electricity from a generator.
Open circuit voltage. The closer to the upper limit (90 V), the better. The optimal range is 40-90 V.
Operating mode at maximum current. The indicator is expressed as a percentage and determines the ratio of the duration of continuous welding work to the total operating time of the device. That is, if an indicator of 60% is indicated, it means that welding can be carried out for 6 minutes, and the unit must rest for 4 minutes. The optimal value is 50-60%, good - from 70%.
Current adjustment method. It is better if the current is regulated smoothly.
Availability of additional functions such as hot start, arc force and anti-stick. The most useful are the hot start and auto-shutdown functions. The first provides a faster start, and the second avoids the consequences of a long continuous operation of the switched on device.

Which is better - inverter or transformer?

Each type of welding machine has its pros and cons. Devices like inverters are smaller in size, more economical in terms of energy consumption, and equipped with a large number of functions.

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

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

Conclusion

When choosing an inverter-type welding machine, it is worth considering, first of all, the voltage tolerances of the device, power, compatibility with various types of metals and functional equipment.

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