GYS NEOMIG-i 400 G – Industrial 400A Multi-Process Inverter Welder

The GYS NEOMIG-i 400 G is a high-performance three-phase multi-process inverter power source designed for advanced industrial welding. Delivering up to 400A at 100% duty cycle, it offers exceptional arc stability and precision for MIG/MAG, MMA, and TIG DC welding applications. Its intelligent digital control system ensures smooth ignition, consistent performance, and reduced spatter across all materials — from steel and stainless steel to aluminium and brazing wires. Equipped with integrated synergy programs, the NEOMIG-i 400 G automatically sets the optimal welding parameters based on wire diameter, gas type, and material thickness. Compatible with WF 35 and WF 50 wire feeders, and optional KOOLWELD 2 liquid cooling, this robust machine is engineered for maximum productivity, reliability, and traceability in the most demanding workshop environments.

Who Is It For + Pros & Cons

The GYS NEOMIG-i 400 G is built for professional welders, industrial workshops, and heavy fabrication facilities requiring a versatile, high-duty cycle power source for multiple welding processes.

  • Pros: 100% duty cycle at 400A, advanced synergy programs, digital control, and multi-process compatibility.
  • Cons: Requires separate wire feeder, higher initial cost, and three-phase power supply.
