Sealey POWERMIG300i 300Amp Gas / Gasless Mig/ MMA / Tig Inverter Welder
The Sealey POWERMIG300i is a versatile multi-process inverter welder offering MIG, TIG and MMA capabilities in a single professional-grade unit. Built around IGBT inverter technology, this 300A welder is engineered for fabrication workshops, professional welders, mechanics and technicians who require flexibility across different welding processes and materials. With a maximum output of 300A, this inverter welder handles steel, stainless steel and aluminium up to 12mm thickness. The unit operates in both gas-shielded and gasless modes, accepting CO2, Argon or mixed gas types for MIG welding. Wire capacity accommodates 5-15kg spools with wire diameters from 0.6mm to 1.2mm, whilst MMA mode accepts electrodes from 1.6mm to 5mm. The 2T/4T torch trigger function provides precise control during extended welding operations, complemented by a clear digital amp and voltmeter display for accurate parameter monitoring. Built-in protection systems guard against short circuit, overheating and overcurrent conditions. The welder features large rear wheels and a low gas cylinder tray for improved mobility and stable gas bottle storage in workshop environments. Duty cycles are rated at 40% at maximum output across all three welding processes: 300A for MIG, 270A for TIG and 270A for MMA. The unit requires a 400V three-phase supply with 8.96kW absorbed power and is supplied with a 2m power cable, 2m earth clamp, 3m Euro non-live MIG torch and 2m electrode holder. The IP21S rating provides protection suitable for workshop use.
