Tweco 1050-1113 Mig Gun 500A 15 Ft Air Cooled

Product Description

The TWECO 1050-1113 is a 500-amp, air-cooled MIG gun built for heavy-duty industrial and fabrication welding. Rated at 60% duty cycle, it handles wire up to 1/16 inch and connects via a Tweco rear connection. The 15-foot cable length gives operators room to work across larger weld areas. The oval-shaped handle is designed to reduce grip fatigue during extended use, and the three-layer conductor tube — copper tube, silicon-resin glass insulator, and metal jacket — supports consistent electrical conductivity. Licensed electricians and certified welders are the primary installers and operators of this gun.

The 1050-1113 is suited for demanding environments including automotive fabrication, shipyard and offshore applications, steel industry work, and general industrial repair and maintenance. The gun supports a wide selection of front-end consumables, including interchangeable components across Tweco Classic No. and Tweco Spray Master series, making it adaptable for varied welding processes in production and field settings. Its balanced, heavy-duty handle design allows use in multiple welding positions without added strain on the operator.
