1) Advanced IGBT inverter technology:
Inverter frequency is 20 KHz, greatly reducing the volume and weight of the welder.
Great reduction in magnetic loss obviously enhances the welding efficiency and energy saving effect. Switching frequency is beyond audiorange,which almost eliminates noise problem.
2)Leading control mode:
Top design of auxiliary power supply brings a broader application scope of welding power supply. Advanced control solution obviously enhances the welding performance and meets welding technology demands to a larger extent. It can be widely used in basic,acid and cellulose electrode welding with excellent welding effect. Easy arc starting, littble spatter, stable current and good shaping.
3) Improved function design:
Adjustment thermal arc starting function greatly improves the arc starting performance of the machine. Self-adaptive arc-force mode greatly improves the welding performance in long cable welding, and distant welding can be realized.
