General Mma Welding Machine - 400x200x350mm, 60% Duty Cycle, 20khz Frequency | Miniature Design, Energy Saving, Stable Welding, Automatic Protection, Versatile Electrodes, Harsh Environment Use

Following are the salient features of General 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.
