Tweco 1044-1128 Water-cooled Mig Gun 500A 10 Ft

Product Description

The TWECO 1044-1128 is a water-cooled MIG welding gun in the Fusion Pro 7W series, designed for high-amperage, continuous-duty welding operations. Rated at 450 amps at 100% duty cycle with mixed gas and 500 amps at 100% duty cycle with CO2, this gun delivers sustained performance where air-cooled guns fall short. The 10-foot cable length gives welders working room around large assemblies and fixtures. Advanced cooling channels in the conductor tube accelerate heat dissipation, extending front-end consumable life up to five times longer compared to gas-cooled guns. A licensed welding professional or qualified fabricator handles installation and daily operation.

This gun is suited for heavy-duty fabrication environments where high heat and extended arc-on time are routine. Typical applications include shipbuilding and offshore yards, tank and pressure vessel fabrication, general manufacturing, automotive body work, and aerospace fabrication. The ergonomic handle reduces operator fatigue during long welding shifts. Wire diameter compatibility spans 0.035 inches to 1/16 inch, covering a broad range of solid and cored wire consumables. The design adapts with most competitive wire feeders and is noted for compatibility with Miller welding equipment.

Compatibility

Designed for use with Miller welding equipment and compatible with most competitive wire feeders. Wire diameter range of 0.035 inches to 1/16 inch suits a wide variety of solid wire and flux-cored wire applications in heavy fabrication settings.

Installation Notes

Installation and service of water-cooled MIG guns must be performed by a qualified welding technician. Power down and de-energize the welding power source before connecting or disconnecting the gun from the wire feeder. Ensure water cooling lines are properly connected, free of kinks, and leak-tested before resuming welding operations. Follow the equipment manufacturer guidelines and applicable AWS and facility safety standards when setting up or servicing the gun.
