Xtrweld 415-3545T Mig Gun Tweco Style 400 Amp 15 Ft

Product Description

The XTRWELD 415-3545T is a professional-grade MIG welding gun built with a Tweco-style rear connector and rated for 400 amps of continuous welding performance. Designed for high-demand fabrication and industrial welding environments, it accommodates wire sizes up to .045 inches and operates at a 60% duty cycle, making it suitable for sustained production work. Compatible with CO2 and mixed shielding gases, the gun is built to handle the full range of common MIG welding processes. Licensed welders and fabricators in industrial, commercial, and heavy-duty repair settings rely on this gun as a direct-fit replacement for standard Tweco-pattern setups.

The 415-3545T is intended for use in wire-feed MIG welding applications where a 400-amp, 15-foot gun is required. Its Tweco-style rear connector allows it to drop into existing Tweco-compatible welder setups without adapter modifications. The 15-foot cable length provides reach flexibility for larger workpieces and positional welding. Typical install scenarios include metal fabrication shops, structural welding operations, automotive repair facilities, and industrial maintenance environments where high-amperage MIG welding is routine.
