Mining Mma Welding Machine

Following are the features of Mining MMA Welding Machine:
1.Arc force adjustment, adapting to acidity, alkaline, cellulose, stainless steel, cast iron and all grades of electrode.
2.Efficient, energy-saving and environmental protection; saving electricity over 60% more than AC welding machine.
3.Humanization design, simple operation, displaying the welding current accurately beforehand.
4.Welding steadily when the welding wire is 100m.
5.When lack of phase, undervoltage, overload, short circuit when outputting, the main engine can protect itself automatically.
6.Adapting generators, steel construction, field construction and all harsh environments.
7.Suitable for iron ores workings.
