262707 - Miller Universal Teflon Liner Kit for Spoolmatic & XR Guns (.030-.035)

Keep Your Spool Gun Running Smoothly

If you weld aluminum, you know the headache of a birdnest. One minute you are laying down a stack of dimes, and the next, your wire stops feeding, burns back to the tip, and you are left with a tangled mess of wire at the drive rolls. Often, the culprit is a worn or dirty liner. The Miller 262707 Universal Teflon Liner Kit is your insurance policy against feeding problems. Designed specifically for the Miller Spoolmatic 15A, 30A, and XR series guns, these liners are made from slick Teflon that lets soft aluminum wire glide through without dragging or shaving.

Aluminum wire is incredibly soft compared to steel. If you run it through a dirty or steel liner, it scrapes off tiny shavings. Over time, these shavings clog up your gun, making the wire stutter. Replacing your liner regularly is the best way to keep your arc stable and your frustration levels low. This kit comes with five replacement liners, so you can swap them out the moment you feel drag. They are 14 inches long, which is the perfect length for the neck of your spool gun or push-pull system.

One of the best features of this kit is the included liner cutter. You can't just snip a Teflon liner with wire cutters—it squashes the tube and pinches the wire. The included tool gives you a factory-perfect cut every time, ensuring the wire enters the contact tip smoothly. Whether you are running .030" or .035" wire, this kit helps you maintain consistent wire speed and high-quality welds. Don't let a cheap consumable ruin your expensive aluminum project; keep a pack of these liners in your toolbox.
