14401136 - Tweco WeldSkill Nylon Liner for 1/16 Aluminum Wire - 15ft

Optimize Your Aluminum Feeding with Tweco 1440-1136

For professional welders, few things are more frustrating than feed issues when running aluminum. The soft nature of the wire makes it prone to buckling and shaving if the wrong liner is used. The Tweco 1440-1136 WeldSkill Conduit Liner is the solution for 15-foot guns running 1/16" (1.6mm) aluminum wire. Identified by the part number WS44N-116-15, this liner features a durable nylon core that drastically reduces friction compared to steel coiled liners.

Why use nylon? Steel liners act like a file against soft aluminum, creating shavings that eventually clog the gun and cause burn-back or erratic arc starts. This Tweco nylon liner provides a smooth, slick channel that allows the wire to glide effortlessly from the feeder to the contact tip. It is designed specifically for Tweco WeldSkill guns, ensuring correct seating at the back end and proper gas flow characteristics. Whether you are welding boat hulls, trailers, or custom aluminum fixtures, reliable wire feeding is the foundation of a good bead.

Installation is straightforward, following standard liner replacement procedures for WeldSkill guns. At 15 feet, it accommodates the reach needed for most shop environments. Don't compromise your aluminum welds with a dirty or incorrect liner. Keep your setup running smooth and your arc stable with this genuine Tweco replacement part.
