MMA Series IGBT Inverter DC Manual Welder

Product Name：MMA Series IGBT MINI Inverter DC Manual Welder

Product Type：MMA-250

1. Digital IGBT inverter welding machine, CPU for self-protection like self-diagnosis and self-control, "pre-safeguard " and milliseconds response time to ensure a steady reliable working environment.

2. National defense level fine accuracy of Current output , suitable for all kinds of basic welding electrode (J506, J507, etc.) and stainless steel, cast iron, copper, aluminum and other electrodes, the additional carbon arc gouging, erection steel welding capabilities and ease of manual TIG welding.

3. Ultra-Portable - 1 / 3 size of ordinary inverter welding machine.

4. Easiness of arc starting, stable welding arc, deep weld pool, forming a good shape, highly constant precisely adjustable continuous output current from 0 to maximum current.

5. Energy efficient (efficiency up to 90%, power factor 0.9).

6. Single control knob, built-in menu to select welding mode easily and set the value to meet the need of accurate control from high-end users.

7. Modular combination for rapid removal, installation, easy maintenance and repair
