1. Unique wave control;
2. Request for high current;
3. suitable for MAG/CO2 welding of low carbon steel and low alloy steel
Main feature:
1. Unique wave control, optimized the wave and arc character of CO2/MAG. Wide adjusting range, stable at both high and low current. Excellent ignition and penetration control, little spatter during welding. Extensive option of arc character for different welding process and operator. The arc is stable and distinctive. Special design circuit prevent arc blowout. There is no arc blowout and little spatter under different welding processes. The control panel is simple and easy to operate. Crater filling, tacking welding, C02/MAG swith, synergic/independent adjustment, solid wire/flux wire switch functions on the panel.
2. Welding request for high current and high duty cycle
Output short circuit protecting, over-heat protecting, overload protecting, over-voltage protecting make human and equipments safe. Solid wire, flux wire weld stable, the formation is good.
