193793 - Miller Spoolmate Teflon Liner .023-.040 (3-Pack)

Smooth Aluminum Feeding with Miller Teflon Liners

Take the frustration out of aluminum welding with the Miller 193793 Teflon Liner 3-Pack. If you use a Spoolmate 3035 or 3545 spool gun, you know that feeding soft aluminum wire can be a delicate process. Standard liners can cause drag, leading to the wire bunching up (birdnesting) at the drive rolls or sputtering at the arc. Miller's genuine Teflon liners are the solution, providing a slick, low-friction path that allows your wire to glide effortlessly through the gun neck.

Designed specifically for the demands of aluminum fabrication, these liners are essential for achieving those clean, consistent "stack of dimes" welds. The Teflon material prevents the soft wire from scraping against the liner walls, which not only ensures smooth feeding but also prevents metal shavings from clogging the tip or contaminating your weld pool. Whether you are welding thin gauge aluminum sheet or heavier structural components, consistent wire delivery is the key to arc stability.

This convenient 3-pack ensures you are always prepared. Liners are consumables that wear out over time, and having a spare on hand means you won't be stuck waiting for parts in the middle of a job. Each liner is pre-cut to the exact 7.188-inch length required for your Spoolmate gun, making installation quick and hassle-free—no measuring or trimming required. They accommodate the most popular aluminum wire sizes, from .023" to .040".

Don't let feed issues compromise your weld quality. Upgrade your maintenance routine with genuine Miller parts. These liners are perfect for automotive restoration, boat repair, and sign fabrication where aluminum is the material of choice. Keep your Spoolmate running like new and experience the difference a fresh Teflon liner makes in your welding performance.
