The Excellent Enterprises MIG-ARC-400 Three Phase IGBT Inverter Welding Machine is the heavy-production flagship of the MIG range — a full industrial platform for fabrication plants, shipyards, railway and pressure-vessel manufacturers and production welding cells where throughput, arc consistency and reliability drive output. It delivers 40–400A of constant-voltage power across MIG/MAG, Flux-Cored and MMA, fed by a separate high-capacity wire feeder on 380–415V three-phase supply.
Product Overview
A full-bridge IGBT constant-voltage power source maintains stable output across changing load for predictable weld quality shift after shift. A separate industrial wire feeder (1–25 m/min) with 5-pin interconnection can be positioned away from the power source for access around large assemblies — a practical advantage on shipbuilding and structural work.
Key Features
- 40–400A CV output across MIG/MAG/FCAW/MMA.
- Separate high-capacity feeder, 1–25 m/min, 5-pin remote placement.
- 0.8–1.6mm wire — mild steel, stainless, aluminium, flux-cored.
- Instant-start + ball-burnback control for clean initiation/restart.
- 2T/4T torch control + digital parameter display.
- 0.93 power factor, 80–85% efficiency, 60% duty.
- Heavy-duty cooling + overload/overvoltage/overcurrent protection.
Benefits
True multi-process capability removes equipment duplication; high deposition + remote feeder raise productivity on big workpieces; CV stability cuts rework. IGBT efficiency controls running cost in continuous production.

Buying Considerations
- In-box package (key): confirm separate feeder, MIG torch (+length), interconnection cable length, gas regulator + hose, spool size, roll type (DATA REQUIRED) — the heavy-MIG buyer’s core comparison.
- Aluminium wire: feasible (0.8–1.6mm); confirm roll/liner/torch setup for aluminium.
- Supply: 380–415V three-phase; confirm input current/KVA + breaker.
- MIG-400 vs MIG-250: step down for medium-duty/integrated-feeder work.

Frequently Asked Questions
What is the MIG-ARC-400 used for? Heavy production MIG/MAG/FCAW/MMA — shipbuilding, pressure vessels, railway, bridge and structural fabrication — on 380–415V three-phase. Is the feeder separate? Yes — a separate high-capacity feeder with 5-pin interconnection for flexible placement. What wire fits? 0.8–1.6mm mild-steel, stainless, aluminium and flux-cored. Does it weld aluminium? It accepts aluminium MIG wire; confirm the aluminium roll/liner/torch setup. MIG-400 or MIG-250? MIG-400 for heavy continuous production with a remote feeder; MIG-250 for medium-duty. What’s the duty cycle? 60% (confirm rated amperage), with heavy-duty cooling for production.
