Tweco 1030-1137 Mig Gun 300A 15 Ft Air Cooled

Product Description

The TWECO 1030-1137 is a Professional No. 3 Classic Series MIG gun rated at 300 amps with a 15-foot power cable and Miller-style rear connection. It is designed for medium- to heavy-duty fabrication work and operates at a 60% duty cycle with CO2 gas. The gun features a three-layer conductor tube construction — copper tube, silicon-resin glass insulator, and metal jacket — and accommodates wire sizes up to 1/16 inches. Air-cooled operation makes it well suited for production and maintenance welding environments. Licensed welding professionals and industrial fabricators are the primary installers and operators of this equipment.

The 1030-1137 fits medium- to heavy-duty fabrication settings including farm shops, maintenance and repair operations, production facilities, and general shop work. The 15-foot cable length provides reach flexibility in fixed and semi-fixed welding stations. The Miller-style rear connection allows direct integration with compatible wire feeders. The fully insulated Mig-Kwik connection enables quick connect and disconnect at the wire feeder without additional tools, supporting faster setup and changeover in active shop environments.

Key Features

• 300A air-cooled MIG gun with 60% duty cycle rating using CO2 gas

• Standard 60-degree conductor tube swivels 360 degrees around the handle and removes without pulling the conduit
• Oval-shaped, high-impact crush-resistant handle balanced at center to reduce operator fatigue across welding positions
• Silver-plated trigger contacts with self-cleaning action on every engagement and disengagement cycle
• Steel spring strain relief at rear of handle minimizes wire feed issues at the Cablehoz exit point
• Split-half handle case allows field repair access to Cablehoz without additional connectors

Compatibility

Designed for use with Miller-style wire feeders via the Miller-style rear connection. Front-end consumables are interchangeable with Tweco Spray Master series and Tweco Professional No. Series MIG guns.

Installation Notes

Installation and setup should be performed by a qualified welding technician or industrial maintenance professional. Always de-energize and power down the wire feeder before connecting or disconnecting the gun at the rear connection. Verify that the conductor tube and Cablehoz are secured with both ball-point screws before initiating any weld. Follow applicable facility safety protocols and equipment manufacturer guidelines during setup and consumable replacement.
