Tweco 1030-1133 Mig Gun 300A 12 Ft Miller Style

Product Description

The TWECO 1030-1133 is a Professional No. 3 Classic Series air-cooled MIG gun rated at 300 amps with a 60% duty cycle using CO2 gas. It accommodates wire diameters from 0.035 to 0.045 inches and features a three-layer metal jacketed conductor tube for reliable current transfer. The 12-foot power cable includes a Miller-style rear connection and a fully insulated Mig-Kwik connector for quick connect and disconnect at the wire feeder. Designed for medium to heavy-duty fabrication environments, this gun is installed and serviced by professional welders and fabricators in industrial, production, and maintenance settings.

The 1030-1133 is suited for medium to heavy fabrication work across farm, shop, production, and maintenance and repair applications. The standard 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced without pulling the conduit, making front-end service fast. The oval-shaped handle is balanced to pivot at its center, reducing grip effort and operator fatigue across varied welding positions. Front-end consumables are interchangeable with the Tweco Spray Master series and Tweco Professional No. series, which helps reduce inventory requirements.
