MMA-500 Welding Machine, 500A DC Inverter

The MMA-500 is a powerful, portable DC inverter stick welder for workshops, fabrication jobs and site repairs. IGBT inverter technology gives a smooth, stable arc and clean welds, and the digital current display makes it easy to set the right amperage. It comes with an electrode holder, earth clamp and face shield, so you can start welding as soon as it’s unboxed.

Key Features & Benefits
