Mma Welding Machine - 3p/380v, 12.5kva, 0-315a | Miniaturization Design, Energy-saving, Automatic Self-protection

Salient features of MMA Welding Machine:
1.Miniaturization design, simple operation, preset the welding current accurately beforehand.
2.It can use acidity, alkaline, cellulose, stainless steel, cast iron and all grades of electrode.
3.Efficient, energy-saving and environmental protection; save over 60% electricity more than AC welding machine.
4.Weld steadily with 100m welding wire.
5.When lack of phase, under-voltage, over-load, short circuit when outputting, the main engine can protect itself automatically.
6.Adapt to generators, steel construction, field construction and all harsh environments.
