The CRUXWELD CWMIG400iJ is an IGBT inverter MIG welding machine with a separate wire feeder and a built-in MMA function. Weld mild steel with gas or gasless flux-cored wire, weld stainless steel and aluminium with the right wire and gas, and switch to stick electrodes for site work — all from one 415 V three-phase power source.

The CWMIG400iJ is a MIG welding machine 400 amp class inverter for medium to heavy fabrication. It pairs ultra-smooth arc characteristics with a separate wire feeder, so one welder can run long production seams in the shop and take the same machine to site.
Its IGBT inverter runs cool and efficiently, holds a stable output across a wide supply tolerance, and adds crater controls to fine-tune the start and end of each weld.
From thin sheet at the low end to multi-pass welds on heavy plate at the top.
MIG/MAG with gas, gasless flux-cored (FCAW) and stick (MMA) from one power source.
Stepless wire speed, 1.5–20 m/min. Carry the feeder to the job; the power source stays at the mains.
Variable inductance and crater controls for less spatter and cleaner starts and stops.
Pick the process for the job, not the machine.
Solid wire with shielding gas for clean, fast welds in the shop.
Self-shielded flux-cored wire makes its own shield, so there is no gas cylinder to carry.
Switch the selector to MMA and weld with stick electrodes.
| Job | Process | Wire or electrode | Shielding gas |
|---|---|---|---|
| Mild steel, in the shop | MIG / MAG | Solid copper-coated MS wire | CO2 or argon/CO2 mix |
| Mild steel, outdoors or on site | FCAW gasless | Self-shielded flux-cored wire | None — no cylinder |
| Stainless steel | MIG | Stainless steel wire | Argon-rich mix |
| Aluminium | MIG | Aluminium wire, with U-groove rolls and a PTFE liner | Pure argon |
| Rusty, painted or hard-to-reach work | MMA | Stick electrodes | None |
Typical setups. Send your material and thickness on WhatsApp and our technical team confirms the wire, rolls, liner and gas.
Two digital displays and three knobs. Here is what each control does.
123456789A four-roll drive pushes the wire steadily to the torch, with stepless speed from 1.5 to 20 m/min.
Two pairs of rolls grip the wire for a steady feed, with a pressure arm on each pair.
Welding voltage and current dials and an inching button on the feeder, right where you work.
Fit the MIG torch to the feeder, the interconnection cable to the power source, and the earth clamp to the job.
Mount the spool, fit drive rolls for your wire size and thread the wire with Check wire.
Choose MIG or MMA and 2T or 4T, then set voltage, wire speed and inductance for the plate.
Check gas flow (or skip it for gasless wire), strike the arc and run the bead.
