Tweco 1044-1136 Water-cooled Mig Gun 500A 15 Ft

Product Description

The TWECO 1044-1136 is a water-cooled MIG welding gun rated at 450 amps at 100% duty cycle with mixed gas and 500 amps at 100% duty cycle with CO2. Part of the Fusion Pro 7W series, it accepts wire diameters from 0.035 inches up to 1/16 inch and features a 15-foot cable length with a Euro-Kwik connection. Advanced cooling channels in the conductor tube deliver faster heat dissipation compared to gas-cooled guns, extending front-end wear part life significantly. The gun is designed for high-heat, heavy-duty fabrication environments and is sized and balanced for extended use by professional welders.

The 1044-1136 suits demanding industrial applications including shipbuilding and offshore yards, tank and vessel fabrication, general manufacturing, automotive body work, and aerospace fabrication. The Euro-Kwik connection adapts with most competitive wire feeders, making it a practical choice for shops running mixed equipment. Its ergonomic handle and lightweight construction reduce operator fatigue during long welding runs. The thick conductor tube adds durability and lowers the risk of damage from accidental drops on the shop floor.

Installation Notes

Installation and service of water-cooled MIG gun systems should be performed by a qualified welding equipment technician. Before connecting or disconnecting the gun, shut off the welding power source and close the water supply valve to prevent leaks or electrical hazard. Verify that the water supply and return lines are properly connected and free of kinks before resuming operation. Inspect the Euro-Kwik connection for secure seating and confirm wire feeder drive roll settings match the selected wire diameter before running wire.
