MIG Welders

MIG welders spanning entry-level to production duty: the Unimig Viper 120 synergic and CIGWELD Transmig 185 Ultra single-phase inverters, the gasless BlueVenom MG130, and industrial 400-amp and 500-amp pulse water-cooled MIG/MAG packages with 10-metre remotes. The category suits everyone from a home workshop running gasless wire to a fabrication shop pushing spray transfer all day.

What size MIG welder do I need?

Match amperage to material thickness and duty cycle. Around 130–185 amps on a standard 10–15 amp outlet handles steel to roughly 8 mm and general repair work. Above 250 amps — usually three-phase — is the territory of structural sections and continuous production, and water cooling earns its keep once you run high amperage for long stretches, keeping torches cooler and consumable costs down.
