Ingco MMA Welding Machine 630A Three-Phase 400V IGBT Inverter
TSh 2,309,000
Our review
This is a heavy-duty manual metal arc welder from Ingco, built around IGBT inverter technology and drawing three-phase power at 380-400V. Its output spans 20 to 630 amps, with a 60% duty cycle at the top end, a no-load voltage of 85V, and support for electrodes from 2.5mm up to 6.0mm. That combination points to fabrication and workshop work on thicker steel rather than light household repairs. Before buying, confirm your supply is genuinely three-phase and can handle the input range, since this machine will not run on ordinary single-phase power. Also note the listing says no accessories are included, so plan for cables, a holder, a clamp, and a helmet separately. Compare it with other three-phase inverter welders on duty cycle at 630A, electrode size range, and whether a package includes the leads you need.
