1. The welding current is minimum from 5A, the arc stabilization performance is good, and a variety of thin, medium and thick plates can be welded;

2. DC pulse argon arc welding is suitable for welding stainless steel, copper, titanium, carbon steel and other materials;
3. When the AC is exchanged, the characteristics of the sag can be obtained. The welding current waveform is a square wave with rapid zero crossing, which is beneficial to the welding current and arc stability;
4. AC argon arc welding is suitable for welding aluminum, aluminum alloy and other materials;

5. It can adjust the pulse base time, the atomization area adjustment, and the gas hysteresis turn-off time adopts stepless adjustment, especially meeting the requirements of higher welding process;
6. It has the functions of AC/DC argon arc welding, AC/DC pulse argon arc welding, AC/DC manual welding, AC/DC spot welding;
7. It has the function of slowening and attenuating the welding current, which is beneficial to fill the arc pit when the arc is closed and avoid cracks in the weld.
