WELPRO 20–200A Inverter Welder Model WEL MMA 200

A high-quality, professional-grade MMA Inverter Welder delivering a full rated welding current of up to 200A. It provides a smooth, stable, and consistent welding arc for reliable welding performance.

The welding current can be precisely adjusted from 20–200A and clearly displayed on the Digital Display, allowing convenient and accurate current adjustment. The machine supports welding electrodes ranging from 1.6 mm to 4.0 mm and is designed for extended continuous welding with 4.0 mm electrodes throughout the day without interruption.

The machine also supports the TIG LIFT function, allowing optional accessories to be connected for Lift TIG welding, providing greater versatility. The MMA polarity can be switched at the front of the machine, allowing the polarity to be selected according to the application and electrode type.

For enhanced safety, the machine features VRD (Voltage Reduction Device), which reduces the output voltage to just 14V during welding standby, helping reduce the risk of electric shock.

Advanced welding assistance technologies include Hot Start (0–100% adjustable) for easier arc ignition, Arc Force (0–100% adjustable) to compensate for welding current fluctuations and maintain arc stability, and a built-in Anti-Stick system that immediately cuts the welding current when the electrode sticks to the workpiece, helping prevent electrode sticking and burning.
