10351136 - Tweco Supra 350A MIG Gun, 15ft, Miller Connection (.035-.045)

Heavy-Duty Tweco Supra 350A MIG Gun for Miller Feeders

The Tweco Supra 350A MIG Gun (1035-1136) is a premium air-cooled welding torch designed to meet the rigorous demands of industrial fabrication. Engineered with the professional welder in mind, this gun combines the legendary performance of Tweco's consumable systems with a robust, ergonomic handle design. It is specifically configured with a Miller-style backend connection, making it a direct plug-and-play replacement or upgrade for compatible Miller wire feeders and integrated MIG machines.

Rated at 350 Amps at 60% duty cycle (using CO2 gas), the Supra 350 is built to handle medium-to-heavy fabrication tasks, including structural steel, heavy equipment repair, and general manufacturing. The 15-foot cable assembly provides ample reach, allowing operators to move freely around large workpieces without constantly repositioning the power source. The cable itself features high-quality copper stranding and a durable outer jacket resistant to cuts, abrasion, and weld spatter.

One of the key technical advantages of this assembly is its utilization of standard Tweco consumables. It comes ready to weld with 14 Series contact tips and 24 Series gas nozzles, which are among the most widely available and cost-effective consumables in the industry. The gun is pre-lined for .035" to .045" (0.9mm - 1.2mm) wire, covering the most common wire diameters used in industrial MIG welding. The fully insulated metal jacketed conductor tube (gooseneck) ensures electrical safety and longevity, while the heavy-duty strain relief systems at both the handle and the feeder pin protect the cable from kinking and premature failure.

This unit is an ideal solution for procurement managers looking to standardize their welding fleet on Tweco guns while maintaining compatibility with existing Miller power sources. Its modular design allows for easy repairs, with replaceable triggers, conductor tubes, and cable liners.
