Tweco 1044-1134 Water-cooled Mig Gun 500A 10 Ft

Product Description

The TWECO 1044-1134 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. Built on the Fusion Pro 7W platform, it features advanced cooling channels in the conductor tube that accelerate heat dissipation, extending front-end wear part life up to five times longer compared to gas-cooled guns. The 10-foot cable and Euro-Kwik connection make it a practical choice for heavy-duty fabrication environments where both performance and welder comfort matter. Licensed welding professionals and fabrication shops handling high-heat continuous welding rely on this gun for consistent, reliable wire feeding.

This gun is designed for demanding industrial and heavy fabrication applications including shipbuilding and offshore yards, tank and vessel fabrication, general manufacturing, automotive body work, and aerospace assembly. The ergonomic handle reduces fatigue during extended welding sessions. The wire diameter range of 0.035 inches to 0.0625 inches (1/16 inch) accommodates a broad range of filler wire selections. The gun adapts with most competitive wire feeders, making integration into existing setups straightforward.

Key Features

• Water-cooled conductor tube with advanced cooling channels extends consumable life up to 5x versus gas-cooled guns
• 10-foot cable length with Euro-Kwik connection for quick feeder integration
• Compatible with wire diameters from 0.035 inches to 0.0625 inches
• Thick conductor tube construction reduces damage risk from accidental drops
• Ergonomic handle design reduces operator fatigue in high-output fabrication environments

Compatibility

Designed for use in heavy-duty MIG welding setups across shipbuilding, tank fabrication, automotive, and aerospace applications. Adapts with most competitive wire feeders via Euro-Kwik connection. Consult TWECO accessory listings for compatible contact tips, gas nozzles, and tip holders.

Installation Notes

Installation and service should be performed by a qualified welding equipment technician. Before connecting or disconnecting the gun, shut down the wire feeder and welding power source and relieve water line pressure if the cooling circuit is active. Verify that the water-cooling supply and return lines are properly connected and free of leaks before operation. Refer to applicable AWS and equipment manufacturer guidelines for safe MIG gun installation and maintenance practices.
