How to choose a welding inverter</a>

Traditional arc power sources, such asWelding units, rectifiers, converters and transformers, have a number of drawbacks: large mass and dimensions, low speed, significant energy intensity, narrow range of adjustment of welding modes. Most of these drawbacks are devoid of welding inverters.

It remains only to choose the suitable unit for you.



When selecting a welding inverter, turnAttention to protection from voltage fluctuations. The level of protection of the household inverter should be about 15%. The inverter for industrial purposes must have a protection of 25%.


A good machine should have an easily removable metal case. This makes it easy to remove dust.


The inverter must be able to work with smallNegative temperatures. These characteristics are indicated in the technical description of the device, on the manufacturers' websites and in catalogs. Note that sudden changes in temperature on the inverter cards cause condensation, which can lead to malfunction of the device. Operation of the device at a temperature below minus 15 ° C can lead to disastrous consequences for the inverter.


The device must be able to charge forBattery. The power reserve is also important. When working with electrodes with a diameter of 3 mm, purchase an inverter for working with electrodes with a diameter of 4 mm - the performance will be higher.


When choosing a welding inverter manufacturerTake into account the availability of catalogs, instructions in Russian. An additional advantage is the availability of service centers. The overwhelming number of aggregates in our market is represented by Chinese manufacturers, therefore the availability of a certificate in this case will practically not matter.


The drawbacks of the inverter include a high sensitivity to dust, which requires regular cleaning and purging of the apparatus. That's why the device should be simple in design.
