10401332 - Tweco SXT415-35-45 Supra-XT 400A MIG Gun 15ft

Tweco Supra-XT: The Standard for Industrial MIG Welding

Elevate your welding performance with the Tweco Supra-XT 400A MIG Gun. With a 15-foot (5-meter) cable and a robust 400-amp rating, this torch is built for the professional who demands consistency and durability. The Supra-XT line represents the evolution of the classic Tweco spray master and professional series, combining time-tested reliability with modern ergonomic enhancements. The SKU 10401332 refers to the SXT415-35-45 model, which is specifically configured for versatility across a wide range of welding tasks, from structural steel erection to heavy equipment repair.

One of the standout features of the Supra-XT is its ergonomic handle. Welding at high amperages for extended periods can take a toll on the wrist and forearm; Tweco addresses this with a handle profile that reduces grip force and improves maneuverability. The trigger mechanism is designed for a crisp, responsive feel, allowing for precise arc initiation and termination. Furthermore, the cable assembly is protected by a heavy-duty jacket and substantial spring strain reliefs at both ends, preventing kinking and wire feed issues that often plague lesser quality guns.

This air-cooled MIG gun is rated for 400 Amps at 60% duty cycle, providing ample power for flux-cored and solid wire applications. It arrives ready to weld with .035" - .045" wire sizes, making it a plug-and-play solution for many standard setups. The backend connection is the classic Tweco style, ensuring compatibility with a vast array of wire feeders and power sources (adapters may be required for specific machine brands). By sticking with the Supra-XT, you also gain the advantage of using standard Tweco consumables—the most ubiquitous and trusted consumable platform in the industry.
