Tweco 1050-1131 Mig Welding Gun 500A 10 Ft Air Cooled

Product Description

The TWECO 1050-1131 is a 500-amp, air-cooled MIG welding gun designed for heavy-duty industrial and fabrication applications. Rated at 60% duty cycle, this gun handles wire up to 3/32 inch and connects via Tweco rear connection. The 10-foot cable length gives welders working room in large fabrication environments. An oval-shaped, high-impact crush-resistant handle reduces grip fatigue during extended operations. The three-layer conductor tube — copper tube, silicon-resin glass insulator, and metal jacket — delivers reliable electrical conductivity under sustained load. Licensed welding professionals and industrial MIG operators are the primary installers and users of this equipment.

The 1050-1131 is suited for demanding applications across automotive, shipbuilding, offshore yards, steel industry work, and general industrial fabrication. Its field-repairable Cablehoz design and split handle case make it practical for maintenance environments where downtime is costly. Front and rear steel spring strain relief minimizes wire feed issues, and front-end consumables are interchangeable between the Tweco Classic No. and Tweco Spray Master series, providing flexibility across multiple gun platforms.

Installation Notes

Installation and operation should be performed by qualified welding professionals familiar with MIG/GMAW equipment. Disconnect and lock out all power to the welding system before connecting or servicing the gun or cable assembly. Verify that the drive roll size, liner, and contact tip match the wire diameter in use. Follow applicable ANSI and AWS safety standards for arc welding equipment setup and operation.
