Welding Machine ARC 400 – 270A ARC Inverter, 3 Phase

The ARC 400 is a 270 A ARC (stick/MMA) inverter welding machine running on 380 V three-phase supply. It is the heavy-duty industrial machine in the Jamshedji ARC welder range — high welding current on a dedicated three-phase connection, for fabrication shops and sites where three-phase power is available and the work runs long and heavy. 5PCB inverter design.

How to choose a welding machine by amperage

An ARC welder is chosen mainly on one number: the welding current it can put out. That current sets how thick a section you can weld and how large an electrode you can run. More amperage lets you burn a bigger rod and drive heat deeper into thick steel; less amperage is easier to control on thin material and draws less power. Every machine in this range does the same job — manual metal arc welding on steel, and other metals — and the choice between them is how much current you need and what power supply you have.

At 270 A the ARC 400 is built for sustained heavy-duty work: thick structural steel, large electrodes and long duty cycles in an industrial setting. It runs on 380 V three-phase power only, which is what suits it to a workshop or site with a dedicated three-phase supply — a three-phase connection carries a heavy welding load more steadily than single-phase. If your supply is single-phase, look at the dual-voltage machines or the single-phase 300 XL instead.

Which welder in the range

The whole range is ARC welding machines; pick by welding current and the power you have.

• 300 X-Bravo — 180 A, 220/380 V: general fabrication, repair and site work; single or three phase.
• ARC 322 — 220 A, 220/380 V: heavier sections; single or three phase.
• X-Bravo — 250 A, 220/380 V: heavy fabrication; single or three phase.
• This ARC 400 — 270 A, 380 V three phase: heavy-duty industrial welding on a dedicated three-phase supply.
• 300 XL — 300 A, 220 V single phase: the highest current in the range, on a single-phase supply.

Applications

Heavy-duty industrial and structural steel fabrication, fabrication shops, workshop and construction welding, repair work on steel, aluminium and other metals — wherever a three-phase supply is available.
