The general principle of it is to make the 50Hz/60Hz AC current into DC current.
And make the DC current into high frequency AC current basing on the high power electronic element IGBT, whose frequency could be 20KHZ, reducing voltage and rectification.
Character:
1.IGBT inverter technology, current controlling model, high quality, steady properties.
2.constant voltage output, high adaptability for electricity network
3.electronic inductor controlling, less splash, deep weld pool and good forming
4.hot start with slow wire feeding, welding with globule wiping off, high hot start success rates.
5.suitable for 0.6mm, 0.8mm thickness welding material
6.small size, light weight, simple operation, multi-process function

The efficiency of machine would be above 85%, and machine would be with energy conservation function
Machine function:
1. MIG no gas weld function (tubular wire)
2. MIG gas shield weld function (solid wire)
3. ARC weld function (MMA)
4. Lift TIG weld function

Weld current and weld voltage adjustable
