The **ESAB MIG 402i** is a high-performance, 3-phase inverter-based MIG/MAG welding machine engineered for demanding industrial fabrication, shipbuilding, structural steel erection, and heavy machinery manufacturing. Powered by advanced IGBT inverter technology, it delivers up to 400A of welding output with approximately 90% energy efficiency and superior arc control compared to conventional transformer-based welders. The system features an external 4-roll drive wire feeder that ensures smooth, slip-free feeding of 0.8 mm to 1.6 mm solid and flux-cored wires even over extended torch lengths. Designed to operate reliably under real-world site conditions, the machine offers a wide voltage tolerance (380V to 460V), digital parameter storage for up to 16 pre-set welding programs, fine voltage adjustment, and robust internal protection to support continuous, high-volume production.
