WELPRO Inverter Welder Model PRO MMA 250S
A professional MMA Inverter Welder designed to solve welding challenges on job sites with unstable power conditions perfectly. Delivering a full rated welding current of up to 200 A, it provides a smooth, stable, and consistent arc. It supports continuous operation with 2.6 to 4.0 mm welding electrodes. Packed with PFC (Power Factor Correction) circuit technology offering a power factor of up to 0.99, it saves energy and can withstand voltage drops as low as 115V while maintaining smooth and stable welding performance. In addition, the machine is engineered to support extension cords up to 200 meters long and works with any market generator sized 5.0 kW or higher, even with THD exceeding 20%. Maximum safety is ensured by the VRD (Voltage Reduction Device) system, which lowers the no-load open-circuit voltage to just 14V to prevent electric shock to the welder. It features a digital display showing real, accurate welding current, and comes complete with 100% pure copper welding and ground cables that conduct current far more steadily than conventional aluminum cables.

Features

Delivers full rated welding current up to 200A, providing stable, soft, and smooth welding (Smooth & Stable)

PFC circuit provides a Power Factor up to 0.99, saving energy and handling voltage drops as low as 115V while continuing normal operation

Compatible with all generator models on the market (5.0 kW and above), even with THD > 20%

Can be used with extension cords running up to 200 meters long without welding current drops

Safer with VRD system reducing no-load voltage to just 14V, preventing electric shock to the welder

Supports continuous and smooth welding with 2.6 mm to 4.0 mm electrodes

Equipped with a digital display showing true welding current, making parameter adjustments easy and accurate

Welding and ground cables made of 100% pure copper, conducting current better, smoother, and more stably than typical aluminum cables

Applications

Ideal for welders working on outdoor jobsites, field projects, crane operations, or remote areas requiring extension cords up to 200 meters long or generator power

Ideal for welders operating in areas with unstable power or frequent voltage drops; the PFC system enables continuous welding with 2.6 - 4.0 mm electrodes even when voltage drops to 115V, along with VRD 14V safety protection
