► IGBT soft technology with high efficiency, high reliability and low loss;
► Wide power grid voltage adaptability, stable cutting current;
► Digital meter shows welding current and welding voltage, welding voltage can be preset accurately;
► Selection function of welding torch by 2 step and 4 step;
► Automatic protection function of low input and over load;
► Striking arc under high voltage and slow wire feed. Smooth and stable arc striking with high success rate;
► Adopting unique feedback control circuit of arc voltage and current, stable welding process, little spatter, strong adaptability of wire extension change, wide adjusting range for matching current and voltage, well-shape weld appearance;
► Adopting high performance ball-eliminating circuit, the diameter of ball on wire end almost the same as wire diameter, high success rate at arc striking;
► Almost suitable for all position welding on the mild carbon steel in thickness 0.8～6mm;
► Widely applied in the fields of automobile, steel furniture, filing cabinet, security door, guard railing, and building decoration.
