GYS NEOMIG-i 500 G – 500 A Multi-Process MIG/MAG Welding Machine

The GYS NEOMIG-i 500 G (Ref. 075092) is a powerful 500 A three-phase multi-process inverter welding power source designed primarily for demanding industrial MIG/MAG welding applications. Used with a separate WF wire feeder, its advanced digital technology, high duty cycle and integrated synergic programs provide excellent arc characteristics, simplified machine setup and precise control of welding parameters.

Designed for versatility, the NEOMIG-i 500 G supports MIG/MAG, MMA DC/Pulse, TIG DC Lift/Pulse and air-arc gouging. For MIG/MAG welding, it accommodates steel and stainless steel wire from Ø0.6–1.6 mm, aluminium and CuSi/CuAl wire from Ø0.8–1.6 mm, and flux-cored wire from Ø0.9–2.4 mm with polarity reversal.

The machine incorporates dedicated synergic programs for Steel, AlMg, AlSi, CrNi and CuSi. By entering only three basic parameters — wire diameter, material/gas combination and material thickness — the NEOMIG-i automatically determines the optimal welding parameters, significantly simplifying setup for the operator. Up to 200 welding programs (Jobs) can also be stored for recurring applications.

For intensive industrial production, the NEOMIG-i 500 G delivers a high duty cycle of 500 A at 60% in MIG/MAG, together with digital arc control for instantaneous ignition and a highly stable arc designed to help reduce welding spatter. It is compatible with the WF 35 and WF 50 separate wire feeders, allowing the system to be configured according to different production requirements.

Built for challenging industrial environments, the machine features an IP23-rated reinforced enclosure, on-demand ventilation to reduce dust ingress and unnecessary power consumption, easy access for maintenance and optional dust filtration. Interconnection cables of up to 20 metres allow the working area to be extended when required.
