The CRUXWELD CWMIG500P is a MIG 500 water cooled welding system for heavy fabrication: an IGBT inverter power source, a built-in cooling unit for the water-cooled torch and a 4-roll wire feeder, all on one trolley. MIG/MAG, flux-cored and stick from the same machine.

At 300, 400, 500 A an air-cooled torch runs hot, and the welder stops before the job does. The CWMIG500P sends coolant through a water-cooled torch, so you can keep the arc on heavy plate, multi-pass fillets and flux-cored runs for the whole shift.
Everything stacks on one trolley — feeder on top, inverter power source in the middle, cooling unit below, gas cylinder on the back — so the whole station rolls to the job as one unit.
The built-in cooling unit circulates coolant through the torch and back, carrying away the heat that a 500 A arc puts into the neck and cable. Red and blue quick couplings on the feeder make the hose connections simple: blue to blue, red to red.
These are starting points — confirm with a trial weld. For your plate and joint, send the details on WhatsApp and our technical team will suggest settings.
