The main circuit of phase-shifting full bridge inverter is adopted, and the reliability of the whole machine is high;
Excellent voltage and current dual waveform control circuit, small welding spatter and beautiful weld formation;
It is easy to operate and can choose extended control cable, which is suitable for welding operation in narrow site and high site;
Digital meter displays voltage and current, humanized design, without cumbersome external welding machine specification setting.
Unique aftt ball removal circuit, no residual ball at the end of welding wire.
Equipped with wire feeding structure with wire straightener, the wire feeding performance is superior, and the stability of arc can be guaranteed when the welding gun is excessively bent.

It has the functions of manual arc welding and gas shielded welding;
Adopt waveform control technology, improve molding and reduce splash;
The wire feeding speed is stable without electromagnetic noise;
High frequency inverter, small size, light weight, energy saving and power saving;
Digital display, welding parameters can be preset accurately;
It is suitable for underground 380v-660v or 660v-1140v power supply in mines and coal mines
It is mainly used in various welding positions of carbon steel, low alloy steel, stainless steel and other ferrous materials;
