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 pr...
