AC MMA Welder

The AC MMA welder uses the armature and forced air system to perform welding on the low-carbon steel structure by using ordinary electrode as the filler material. Fast arc-ignition, stable electric arc, wide-ranging adjustment electricity, and overload protection are the major advantages of the AC MMA welding machine.

Various steel structures can be welded by this MMA welder, including the low-carbon steel and alloy steel. Additionally, large-power models can be used for electric arc cutting.

Features
1. The arc welder housing is made of 1.2mm or 1.5mm thick cold-rolling steel plate. Holes are punched in the housing to facilitate heat dissipation. On the top is installed the handle or lifting hook. Wheels are mounted at the bottom to make it easier to move the AC MMA welder.
2. The iron core of the transformer is made of imported silicon steel sheet that allows maximum magnetic flux. Cone-shaped armature is available with the shock-proof mechanism to ensure quiet operation.
3. The copper wire color is T2 purple. It is wound into a coil. Between 2 layers is Teflon seal tape to enhance the insulation.
4. Stable electric arc produces little weld flash and deep weld, which ensures maximum weld quality.
5. Simple structure, high operating stability, and convenient repair and maintenance greatly reduce the breakdown time of the MMA welder which causes decreased productivity.
