1. It uses advanced IGBT contravariant technology;

2. The arc current, the thrust current can be adjusted continuously, the welding stability, the weld forming is beautiful, can weld carbon steel, stainless steel, heat resistant steel and composite steel plate;

3. The arc of the arc of the arc welding and the arc of the arc, the high success rate of the arc. The reverse frequency is 20KHZ, light weight, small volume, easy to move;

4. It is easy to operate in a two-wheel drive, flexible wire, which ensures the steady and reliable delivery of the silk; 

5. Automatic back-pumping circuit;

6. A protective circuit that is fully developed;

7. The noil arc pressure compensation feature makes the welding work at its best;

8. The noil current output, the arc stabilization, the welding quality is more assured;

9. The multi-function manual arc welding, submerged arc welding and carbon arc gouging.
