The Duralloy 501 MultiMIG is a 500A industrial multi-process welder with a separate four-roll wire feeder, designed for heavy fabrication, general fabrication and structural steel work.
Operating from a 415V three-phase supply, the Duralloy 501 MultiMIG supports MIG, TIG and MMA welding. It is suitable for welding mild steel, aluminium and stainless steel.
The heavy-duty four-roll geared wire-feed system provides reliable wire feeding, while waveform control supports a stable arc, even at low current. The separate wire feeder and 10m interconnection kit provide greater working flexibility for larger workshop projects.
The machine incorporates a Voltage Reduction Device for operator safety, together with temperature, voltage and current protection sensors. Protective front fascia covers, industrial cable connectors and industrial castors provide added protection and mobility in demanding working environments.
