Cruxweld makes three 400 A MIG welding machines. All weld the same wire sizes and plate; they differ in weight, efficiency and how they handle rough power.
| Technology | Model | Current | Input | Choose it for | Page |
|---|---|---|---|---|---|
| Inverter | CWMIG400iJ | 40–400 A | 16 kVA, 415 V ±15% | Lightest, most efficient, best arc control for daily production | MIG 400 inverter |
