It remains only to choose the right unit for you.



When choosing the welding inverter payattention to protection from voltage fluctuations. domestic inverter protection level should be about 15%. Inverter for industrial purposes must be protected 25%.

These characteristics are specified in the technical specification of the machine, on the manufacturers' websites and in catalogs. Note that when abrupt temperature changes on the inverter boards appear condensate, which can lead to failure of the device. Work machine at a temperature below minus 15 ° C can lead to disastrous consequences for the inverter.


The device should be able to charge forbattery. Also important is the headroom. When the electrodes 3 mm purchase inverter for electrodes with a diameter of 4 mm - performance will be higher.


When choosing the welding inverter manufacturerconsider the availability of catalogs, instruction in Russian. An additional advantage is the availability of service centers.
