The digital display can adjust the current in time and know the condition of the operator. Advanced IGBT technology, ensures a stable and large power welding work. The volume and weight of the welder are greatly reduced. High frequency inverter, features quick arcing and less welding splash. The advanced intelligent digital display control improves the performance of the welding machine, and the product has the characteristics of small splash, stable current and good forming. Inverter energy saving, first-class energy saving. In addition, the noise is reduced, the overall efficiency of the w elderis improved, and the energy saving effect is more remarkable.
