Tweco 1047-1032 Mig Gun 400A 15 Ft Miller Connection

Product Description

The TWECO 1047-1032 is an air-cooled MIG welding gun rated at 400 amps with a 60% duty cycle when used with CO2 shielding gas. It accommodates wire diameters up to 1/16 inch and features a 15-foot power cable with a Miller style rear connection. The conductor tube uses a three-layer construction: a copper inner tube, a silicon-resin glass insulator, and an outer metal jacket. The 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced without pulling the conduit. This gun is built for light to medium duty fabrication work performed by professional welders in shop and industrial environments.

The TWECO 1047-1032 suits a wide range of applications including farm and maintenance work, garage fabrication, production welding, artistic metalworking, and general shop jobs. Its Miller style rear connection makes it a practical replacement or upgrade for setups already running Miller-compatible wire feeders. The fully insulated Mig-Kwik connection allows quick connect and disconnect at the wire feeder, reducing downtime during wire changes or gun swaps. The front and rear spring strain relief extend cable life in demanding production environments.

Installation Notes

Installation and gun changeover should be performed by a qualified welder or welding equipment technician. Disconnect power to the wire feeder before connecting or disconnecting the gun at the rear fitting. Verify that the wire liner and drive rolls are matched to the wire diameter in use before running a weld. Follow the equipment manufacturer guidelines and applicable NFPA 70E electrical safety practices when servicing welding equipment.
