IGBT inverter DC arc welding machine

Certification

Features:

1.Advanced soft switch inverter technique could solve the IGBT easily broken problem2.The series have the function of regulating striking arc current and thrust current; it is easy to striking arc, with stable arc and good weld shape.3.Arc thrust can be adjusted as changing the cable length. Remote welding is available.4.Small volume and weight, and lower need of electricity.5.ZX7-ST series can be used in every walk of life: electric power construction, nuclear power setting, petrochemi-cal production and piping construction. They is manual welding and TIG dual use welding machine.6.ZX7-400B series can realize downward-welding by using cellulose electrode.7.Multi-stations DC arc welding machine can be produced if required.8.Available remote control box.
