MPT Inverter Welding Machine MIGMAGMMATIG350A

Description

The MPT MIGMAGMMATIG350A is the most powerful multi-process welder in the MPT range. It’s built for fabrication shops, steel contractors and industrial users who need high output and complete flexibility from a single machine.

Four processes in one:

• MIG (metal inert gas), 40–350A: wire welding with argon or argon-mix shielding gas. It’s fast, clean and consistent, and ideal for stainless steel, aluminium-compatible setups and high-quality production welds.
• MAG (metal active gas), 40–350A: wire welding with CO₂ or CO₂/argon mix, the most economical and common choice for mild and carbon steel fabrication, with deep penetration and fast travel speeds.
• MMA / stick, 20–350A: strong, versatile welding for outdoor work, thick structural steel, beams, columns and repairs on rusty or painted metal.
• TIG, 10–350A: precise, spatter-free welds for stainless steel, pipes, thin metal and visible joints, with a low 10A minimum for fine control.

350A of power: the high output lets you weld thick plate in fewer passes, run larger wire and electrodes, and keep productivity high on heavy fabrication jobs. That makes it a strong choice for structural steel, trailers, heavy machinery, steel frames and industrial repair.

Inverter technology gives a stable arc, smooth wire feeding and consistent results in a far more compact package than a transformer welder of the same power. A 60% rated duty cycle allows longer welding before the machine needs to cool down. The 65V max no-load voltage gives easy, reliable arc starts.

Easy control: the front panel has a display and dual adjustment knobs for setting current and voltage or wire speed. A Euro-style MIG torch connector and quick-connect output sockets make it fast to switch between processes.

Built to last:

• Class F insulation: high heat resistance for long service life
• IP21S protection: guards against solid objects and vertically dripping water
• Rugged housing with protective corner frames and an aluminium carry handle
• Large ventilation grilles: efficient cooling during long, high-amperage sessions

It runs on 220–240V, 50–60Hz single-phase power with a 17.3 kVA rated input capacity, so it needs a dedicated heavy-duty circuit. It’s a professional-grade, all-in-one welder for fabrication shops, steel contractors, auto and heavy equipment repair, shipyards, farms and industrial maintenance.
