Inverter DC Arc Welding Machine (Digital Display)(MMA)

Applications and Features:
Be able to use all kind of welding rods, such as acid, basic, J507, J508 and stainless steel rods.
Can be used for welding various steel structure material including pressure vessels.
Excellent dynamic characters, stable welding arc and a good shape of welded seam.
Automatically compensating to the fluctuation of voltage from supply network and keeping a stable current under cold & hot state of the machine.
An excellent replacement of welding machinery of ZX5 & BX series.
Saving energy than BX series by over 50%.

Wide Range of Use
ZX7-400/500/630 are able to use various welding rods, such as J422, J506, J507, J508, cast iron and stainless steel rods, etc. For BX-1315/400 use acid(J422) rods only.

Much Lower for Using Cost
The effectual power of BX1 series only equals to 70% of Inverter DC MMA welding machine.
The effect of whole BX1 series only equals to 50% of Inverter DC MMA welding machine.
Saving electric energy more than 50%, equally saving one welding machine per quarter.
