10401884 - Tweco Supra XT 400A MIG Gun, 15ft, Miller Style, Velocity Consumables

Heavy-Duty Industrial Performance

The Tweco Supra XT 400A MIG Gun (SKU: 10401884) is a premium air-cooled welding torch engineered for high-deposition industrial fabrication environments. Designed to meet the rigorous demands of structural steel, heavy equipment manufacturing, and general metal fabrication, this gun is rated for 400 amps at a 60% duty cycle with CO2 gas. The assembly features a 15-foot cable, providing significant reach and mobility for operators working on large assemblies or fixtures.

This specific model is configured with a Miller-style back-end connection, ensuring seamless plug-and-play compatibility with a wide range of Miller wire feeders and power sources. The direct connection eliminates the need for adapters, ensuring a secure electrical interface and consistent wire feeding performance. The cable assembly is constructed with high-quality copper stranding and a durable, abrasion-resistant outer jacket, designed to withstand the mechanical stresses of a busy shop floor.

Advanced Velocity™ Consumables

A key technical advantage of this Supra XT gun is the integration of Tweco's Velocity™ consumable system. Unlike traditional threaded contact tips, Velocity tips utilize a threadless, drop-in design that maximizes surface contact for superior electrical conductivity and heat dissipation. This results in a more stable arc, reduced spatter, and significantly longer consumable life. The gas diffuser and nozzle are engineered to provide optimal shielding gas coverage, reducing the risk of porosity in the weld pool. The gun's conductor tube (gooseneck) is built to resist high radiant heat, further enhancing the tool's longevity in high-amperage applications.
