14401142 - Tweco WS44-564-15 MIG Gun Liner 1/16-5/64in 15ft

Smooth Feeding for Heavy Wire Welding

Is your wire stuttering, surging, or burning back to the tip? If you are running heavy wire like 1/16" or 5/64" through a 15-foot gun, a worn-out liner is often the culprit. The Tweco 1440-1142 (Model WS44-564-15) is the direct replacement conduit you need to get your machine running smoothly again. Designed specifically for the demands of thicker welding wires, this liner provides a stable and low-friction path for the wire to travel, ensuring that what you set at the feeder is exactly what you get at the puddle.

Over time, MIG liners become clogged with copper dust, dirt, and metal shavings, or they can develop kinks that disrupt the wire feed. This is especially true with larger diameter wires which require more force to push. The Tweco 1440-1142 is built from robust zinc-plated spring steel to withstand this abrasion and pressure. The 15-foot length is standard for many shop floor setups, giving you the reach you need around large workpieces. If your gun is shorter than 15 feet, this liner can easily be measured and trimmed to fit your specific handle and power pin configuration.

Installing a fresh liner is one of the cheapest and most effective ways to improve your welding performance. A good liner prevents "bird-nesting" at the drive rolls and ensures a stable arc, which is critical when welding thick plate or structural components. This particular model fits Tweco WeldSkill guns and many other torches compatible with Tweco 44-series consumables. Don't let a cheap, clogged spring ruin your welds or waste your expensive wire. Keep a spare Tweco 1440-1142 in your toolbox and ensure your heavy-duty MIG setup is always ready for action.
