Polymak 400A 17kW IGBT ARC Welder Industrial Fabrication PM-MMA400-DY

Industrial 400A single-phase IGBT ARC welder with 60% duty cycle for heavy fabrication, shipbuilding, and structural steel welding applications.

With 85% efficiency and an adjustable arc force (1–10) for stable arcs on 2.5–4.0mm electrodes, the Polymak PM-MMA400-DY produces 20–400A output using cutting-edge IGBT-tubular technology. This small, 11.3 kg machine can handle extended welding sessions in metal fabrication yards, construction sites, and maintenance shops that need deep penetration welds on thick plates and structural steel. It has an input power rating of 17kW and a circuit voltage of 54V.
