◆The electrode with more than Φ4.0mm  can weld constantly under the high temperature of 40℃.◆It can use acidity,alkaline,cellulose,stainless steel,cast iron and all grades of electrode.◆ Efficient,energy-saving and environmental protection; save orver 60% electricity more than AC welding machine.     ◆Weld steadily with 100m welding wire.

◆When lack of phase, under-voltage, over-load, short circuit when outputing, the main engine can protect itself automatically.

◆Adapt to generators, steel construction, field construction and harsh environments.
