Advanced IGBT inverter technology is adopted for accurate feedback control, and the current output is stable;

High load continuity, with arc striking current and current thrust adjustment function;

It has the function of automatic compensation for voltage fluctuation, stable arc, uniform molten pool, small spatter and beautiful weld formation;

The fan adopts isolation structure to prevent rainwater from entering;

Power saving design, no arc at five second interval, automatically cut off the power supply of the main circuit, safe and reliable.

Mine and coal mine underground 380v-660v or 660v-1140v power supply.

Suitable for welding carbon steel, alloy steel, cast steel, stainless steel, copper and alloy.
