Cigweld Transmig 500HD Welder – Water Cooled

Cigweld Transmig 500HD Water Cooled is a heavy-duty multiprocess welding system built for demanding industrial fabrication and high-volume welding tasks. This Cigweld multiprocess inverter delivers outstanding performance across MIG, STICK, DC Lift TIG, and gouging applications. The unit is backed by a 5-year warranty.

For applications involving constant high amperage, a water-cooled package is the ideal choice. Cigweld has developed a water-cooled MIG gun that uses a lighter power cable, helping to enhance fabricator performance by reducing fatigue, minimising heat, and extending consumable life.

This 3-phase 500A industrial welder is intended for professional and industrial environments and is not suited for DIY use.
