230235 - Miller .030-.035 Teflon Jump Liner for XR-Aluma-Pro

Smooth Feeding for Tough Aluminum Jobs

If you are welding aluminum with a Miller XR-Aluma-Pro or Pistol-Pro gun, you know that feed problems can ruin your day. The Miller 230235 Teflon Liner is the specific replacement part you need for the head tube (neck) of your gun when running .030 to .035 aluminum wire. Aluminum wire is soft and unforgiving; if it hits a snag or a rough spot in the liner, it buckles, shavings build up, and your arc starts sputtering. This liner is made from pure Teflon to make sure that wire slides through the bend in your gun's neck with zero resistance.

This isn't the long liner that goes all the way back to the feeder; this is the short, 6-inch "jump" liner that lives inside the gooseneck. That bend is exactly where most feed problems happen. Over time, heat and the constant friction of the wire can wear out the inside of the liner or cause it to get clogged with aluminum oxide and shavings. Swapping out this liner is a quick fix that can instantly restore the buttery-smooth feeding you expect from your push-pull gun. It is designed to work perfectly with the Centerfire front-end parts on your Miller gun.

Don't let a worn-out $10 part cost you hours of frustration and rework. Keep a few of these Miller 230235 liners in your toolbox. When you notice your wire speed fluctuating or you feel drag in the gun, pop the neck open and replace the liner. It’s a simple maintenance step that keeps your puddles wet, your beads flat, and your production moving. Whether you are building boat hulls, trailers, or signage, this Teflon liner helps you lay down perfect aluminum welds every time.
