POWERMIG500Wi 500Amp Gas Gasless Mig MMA Tig Inverter Welder

The Sealey POWERMIG500Wi is a professional multi-process inverter welder offering MIG, MMA, and TIG capabilities with an impressive 500A maximum output. This heavy-duty welding system is engineered for demanding workshop environments, professional fabricators, mechanics, and technicians who require versatile welding performance across different metals and applications. Built around advanced IGBT inverter technology, this welder handles both gas and gasless MIG welding alongside traditional stick and TIG processes. The system accommodates steel and stainless steel materials up to 20mm thickness, making it suitable for structural fabrication, vehicle repair, and general metalworking applications. Wire capacity ranges from 5-15kg with diameters between 0.6mm and 1.6mm, whilst electrode capability spans 1.6mm to 5mm. A standout feature is the portable wire feeder, which provides access to confined or elevated work areas that would typically prove difficult with conventional equipment. The integrated water cooling system maintains optimal torch temperature during extended welding sessions, enhancing productivity and extending duty cycle performance. All three processes deliver 60% duty cycle at the full 500A output, ensuring consistent professional-grade performance. The 2T/4T torch trigger function offers enhanced control during lengthy welds, allowing operators to lock the trigger for sustained operation. This 400V three-phase system requires bare wire connection and comes supplied with essential accessories including a 2m power cable, 2m earth clamp, 3m Euro non-live MIG torch, and 2m electrode holder. The water cooler uses distilled water with an 8L/min feed rate and 6L tank capacity.
