M1509 - Miller Style Teflon Liner for .030-.035 Aluminum Wire

Smooth Feeding for Frustration-Free Aluminum Welding

If you are welding aluminum with a Miller MIG gun, you know the struggle of bird-nesting and erratic wire feeding. The Miller Style Teflon Liner (.030-.035) is your solution. Designed specifically to replace standard steel coiled liners, this Teflon conduit is the industry standard for running soft aluminum wire. Steel liners act like a file against soft aluminum, shaving off micro-particles that clog the gun and causing drag that leads to wire pile-ups at the drive rolls. This Teflon liner eliminates that friction, letting your wire glide smoothly right to the puddle.

This specific liner is sized perfectly for the common aluminum wire diameters of .030" and .035". Whether you are working on an aluminum truck bed, repairing a boat, or doing custom fabrication, this liner ensures your machine delivers wire consistently. Consistent wire speed means a stable arc, better penetration, and nicer-looking beads. It is designed to fit most standard Miller MIG guns (M-Series and compatible), making it an easy swap-out part for your existing torch.

Don't let equipment issues slow down your production. Converting your gun for aluminum takes just a few minutes, but using the right liner makes all the difference in the world. This liner is flexible yet durable, resisting the kinks that can happen in a busy shop environment. Remember to keep your gun cable as straight as possible when welding aluminum, even with a Teflon liner, to get the absolute best performance. Equip your torch with this high-quality consumable and stop fighting your wire feeder.
