Tweco 1047-1027 Mig Gun 400 Amp 15 Ft Miller Style

Product Description

The TWECO 1047-1027 is an air-cooled MIG welding gun rated at 400 amps and built for light to medium duty fabrication work. It accommodates wire sizes from 0.035 to 0.045 inches and delivers a 60% duty cycle when used with CO2 shielding gas. The 15-foot power cable features a Miller style rear connection and is engineered for consistent wire feedability. The conductor tube uses a three-layer construction: a copper inner tube, a silicon-resin glass insulator, and a metal outer jacket. The standard 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced without pulling the conduit. The fully insulated Mig-Kwik connection allows quick connect and disconnect at the wire feeder.

This MIG gun is suited for a wide range of applications including farm and shop maintenance, garage fabrication, production welding, and artistic metalwork. The oval grip handle is designed to reduce operator fatigue during extended use. The split-half handle case gives field technicians direct access to internal components for on-site repair without additional connectors. Front and rear spring strain relief extend cable service life in demanding shop environments.
