The Tweco Style 42-3035-15 MIG Gun Liner is a premium aftermarket replacement conduit designed to restore the performance of your MIG welding assembly. Engineered to meet or exceed OEM specifications, this liner is identified by the industry-standard part number 42-3035-15 (also cross-referenced as 1420-1113). It is specifically manufactured for use with welding wires ranging from .030 inches to .035 inches (0.8mm - 0.9mm) in diameter, making it a versatile choice for general fabrication and light-to-medium industrial applications.
Construction quality is paramount in wire feeding systems. This liner features a zinc-plated spring wire body. The zinc plating serves a dual purpose: it significantly minimizes corrosion on the metal surface, which is crucial for maintaining a smooth internal path for the welding wire, and it reduces the coefficient of friction. This results in consistent wire delivery to the contact tip, reducing drag on the drive rolls. The liner is wound to precise tolerances to ensure flexibility without collapsing or kinking inside the cable assembly.
At the back end of the conduit, a machined brass alloy stop is crimped securely to the spring wire. This brass stop is essential for proper seating within the power pin or gun adapter, ensuring gas sealing and electrical continuity where applicable. For ease of inventory management and verification, the part number is roll-stamped directly onto the outside surface of the brass stop.
This 15-foot liner is designed for compatibility with a wide range of popular MIG guns rated between 180 and 250 Amps. It is a direct fit for Tweco Professional Choice No. 1 and No. 2 series, Spray Master MS250, and Eliminator EL250 series MIG guns. It also fits Tweco Weldskill and Fusion series guns (140A, 180A, 220A, 250A). Whether you are maintaining a fleet of production welders or a single shop machine, this liner provides the reliability required for continuous operation.
