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 pollution.

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 the larger extent.
It can be widely used in acid, basic electrode welding.
Easy arc starting, little spatter, stable current and good shaping.

3)Improved functional design
Adjustable thermal arc starting function obviously improves the arc starting performance of the machine.
