Smooth Feeding for Superior Welds

Is your wire stuttering or feeding inconsistently? It might be time to replace your liner. The Tweco 44-3545-15 MIG Gun Conduit Liner is the backbone of a reliable welding setup, designed to keep your wire moving smoothly from the feeder to the contact tip. Built for the popular .035" to .045" wire sizes, this 15-foot liner is the standard choice for welders using Tweco MIG guns who demand consistent performance and minimal downtime.

Why Choose the 44 Series Liner?
Friction is the enemy of wire feeding. That's why Tweco constructs this liner from zinc-plated spring steel. The plating doesn't just prevent rust; it creates a slick surface that allows the wire to glide effortlessly, reducing the strain on your drive rolls and preventing the dreaded "bird-nesting" at the feeder. Whether you are running solid steel wire or flux-cored wire, this liner maintains its shape and integrity even when the gun cable is bent or twisted during operation.

Easy Installation and Fit
This liner is designed as a direct replacement for Tweco No. 3, 4, and 5 guns, as well as many other compatible systems. It comes with a generous 15-foot length, allowing you to trim it for a perfect fit at the diffuser end. A fresh liner restores the crisp, responsive feel of your MIG gun, ensuring that when you pull the trigger, the arc strikes instantly and maintains a steady burn. Don't let a worn-out liner compromise your weld quality—upgrade to the Tweco 44-3545-15 and experience the difference in feedability.
