Tweco 1047-1057 Mig Gun 400A 15 Ft Euro-kwik

Product Description

The TWECO 1047-1057 is an air-cooled MIG welding gun rated at 400 amps and designed for light to medium duty fabrication work. It accommodates wire sizes up to 1/16 inch and delivers a 60% duty cycle when used with CO2 shielding gas. The 15-foot power cable provides consistent wire feedability and connects to the wire feeder via a fully insulated Mig-Kwik connector. The conductor tube uses a three-layer construction — copper tube, silicon-resin glass insulator, and metal jacket — for durability under sustained use. Front and rear spring strain relief protect the cable at both connection points. This gun is installed and serviced by welding technicians in production, maintenance, and fabrication environments.

The 1047-1057 is suited for a range of applications including farm and shop maintenance, light industrial fabrication, artistic metalwork, and garage or production settings. The Euro-Kwik style rear connection makes it compatible with Euro-style wire feeders. The standard 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced quickly without pulling the conduit, reducing downtime during consumable changes or field repairs.
