10231085 - Tweco Fusion 250 MIG Gun, 15ft, Lincoln Connector, .035-.045 Wire

Industrial-Grade Tweco Fusion 250 MIG Gun for Lincoln Feeders

The Tweco Fusion 250 MIG Gun (Stock Code: 1023-1085) is a robust air-cooled welding solution engineered for professional fabrication and industrial manufacturing environments. Designed specifically to interface with Lincoln Electric wire feeders, this gun features a direct Lincoln rear connection, eliminating the need for adapter kits and ensuring a solid electrical and gas connection immediately out of the box. With a rated output of 250 Amps at a 60% duty cycle, it is perfectly suited for structural steel work, heavy equipment repair, and general manufacturing tasks.

A defining feature of the Fusion series is the integration of Tweco's patented Velocity™ consumable platform. Traditional MIG guns often suffer from contact tip loosening and poor conductivity due to threaded designs. The Velocity system utilizes threadless, drop-in contact tips that lock securely into place, providing a larger surface area for electrical transfer. This design keeps the tip cooler, significantly extends consumable life, and produces a more focused and stable arc. The gas flow path is also optimized through the contact tip itself, ensuring superior shielding gas coverage and reducing porosity in the weld.

This specific model, the FV215L3545, comes equipped with a 15-foot cable assembly, offering operators the flexibility to maneuver around large fixtures without moving the power source. The gun is factory-configured with a liner and contact tip suitable for .035" to .045" (0.9mm - 1.2mm) solid or flux-cored wires, covering the vast majority of industrial wire welding applications. The outer cable jacket is constructed from high-grade, abrasion-resistant materials to withstand the rigors of a busy shop floor, protecting the copper conductors and gas hose within.

For maintenance teams and procurement managers, the Tweco Fusion 250 represents a smart investment in efficiency. The simplified consumable stack means fewer parts to stock and faster changeovers, reducing overall downtime. Whether you are welding mild steel or stainless steel, the Fusion 250 delivers the consistency and reliability required for high-quality production welding.
