MMA Welder

Descriptions:

The professional MMA welder is a high quality welding unit. It is capable of producing smooth, stable AC electric arc which is suitable for welding carbon steel, alloy steel, stainless steel and various other materials.

Various electrodes can be used on our MMA welder including the hydrogen electrode and one made of stainless steel. This arc welding unit delivers high welding stability, with limited weld flash and no protruding weld. The resulting weld is nearly seamless, and thus can have clear X-ray image.

If you are considering buyig a set of inverter welders to be used in shipbuilding industries, offshore oil platform, water tower, oil storage tank, and pipeline welding applications, or workshop construction and maintenance works,this MMA welder series might be your best bet.

Features:

1. IGBT technology enables high output power with duty cycle up to 60%. Made with reliable quality, this MMA welder is suitable for welding large-scale steel plant and shipbuilding factory.

2. Computer control system has the functions of automatic fault diagnosis and operation protection. Pre-safeguard technology, coupled with millisecond response time ensure high stability of the whole machine.

3. This inverter welder is able to strike arcs easily and produce deep welds. The resulting weld has an attractive surface.

4. Modular design allows fast installation, disassembly, and easy repair and maintenance.
