WELPRO PRO MMA 140 IGBT Inverter Welder

A professional-grade IGBT Inverter MMA Welder delivering a full rated welding current of up to 140A, providing a smooth, stable, and powerful welding arc.

Specially designed for welding high-grade and difficult-to-melt electrodes such as 3.2 mm E7018 electrodes, the machine can operate continuously throughout the day without interruption or unexpected shutdown.

The machine features convenient front-panel MMA polarity switching, allowing the welding polarity to be selected according to the application and electrode type.

It comes equipped with 100% pure copper welding and ground cables, providing excellent current conductivity, stable welding performance, high heat resistance, and better power-loss prevention compared with conventional aluminum cables.

The welder also comes with a high-quality Aluminium Case, specially designed to neatly accommodate the machine and all standard accessories, making storage and transportation to job sites more convenient.
