230242 - Miller 230242 Teflon Jump Liner for Aluminum Wire (.047-1/16 in)

Smooth Aluminum Feeding with the Miller 230242

Welding aluminum can be a headache if your equipment isn't set up correctly, and often the problem lies in the smallest details. The Miller 230242 Teflon Neck Liner is the unsung hero of your aluminum MIG setup. Designed to sit right in the curved neck of your gun, this 6-inch liner replaces the standard steel coil that would otherwise chew up your soft aluminum wire. If you've ever experienced erratic feeding, burn-backs, or the dreaded birdnest at the drive rolls, a worn-out or incorrect neck liner could be the culprit.

This liner is built for 3/64" (.047) to 1/16" (.062) wire, covering the most common sizes for industrial aluminum fabrication. Because it is made of Teflon, it allows the wire to slide through the bend of the torch with almost zero resistance. This is exactly what you need to keep a steady arc and produce those stack-of-dimes welds aluminum is famous for. It acts as a smooth tunnel, protecting the soft wire from abrasion and ensuring it hits the contact tip straight and true.

Installation is straightforward, making it an easy maintenance item to keep in your kit. Whether you are running a dedicated aluminum rig or swapping over a push-pull gun, ensuring you have a fresh Miller 230242 installed means less downtime fixing feed issues and more time welding. Don't let friction ruin your bead; stick with genuine Miller parts for reliable performance.
