Is your MIG wire stuttering, slipping, or burning back to the tip? The culprit is often a dirty or worn-out liner. The Tweco 45-3545-15 MIG Gun Conduit is the industry-standard replacement for welders running .035" to .045" wire in 15-foot guns. Known for its rugged reliability, this liner is built from wound spring steel that resists kinking while guiding your wire smoothly from the feeder to the contact tip.
Why Replace Your Liner?
Over time, copper dust, shop grime, and metal shavings accumulate inside your gun's liner, creating friction. This friction causes the drive rolls to slip or the wire to feed unevenly, resulting in a wandering arc and frustrating downtime. Installing a fresh Tweco 45-3545-15 liner restores that "like-new" feeling to your MIG gun, allowing you to focus on laying down perfect beads rather than fighting your equipment.
Installation Tips:
This 15-foot liner is designed to be trimmed to the exact length of your specific gun setup. It features a zinc-plated finish that helps the wire slide easily, reducing the load on your wire feeder motor. Whether you are welding mild steel in a fabrication shop or doing repairs in the garage, keeping a spare liner on hand is the smartest way to prevent unexpected stoppages. Compatible with most Tweco-style MIG guns, this is the go-to liner for standard steel wire applications.
