136683 - Miller Spoolmatic Teflon Barrel Liner .045-1/16 (3-Pack)

Smooth Aluminum Feeding with Miller Spoolmatic Liners

If you are welding aluminum with a Spoolmatic or XR pistol-grip gun, you know that feeding issues are the enemy of productivity. The Miller 136683 Teflon Liner is your first line of defense against erratic feeding and burn-backs. Designed to sit inside the barrel of your gun, this liner provides a slick, friction-free path for soft aluminum wire as it travels from the drive rolls to the contact tip.

Why use Teflon? Unlike steel liners used for MIG welding steel, Teflon doesn't scrape or shave soft aluminum wire. Shavings can clog your tip or liner, causing the wire to stick and the feed to stop—usually right in the middle of a critical bead. By using this genuine Miller Teflon liner, you ensure that your .045 or 1/16 inch wire glides smoothly, giving you the consistent arc control you need for precision aluminum work.

This kit comes with three liners, so you can keep spares in your toolbox. Changing the liner is a quick maintenance task that can save you hours of frustration. Simply remove the old liner from the barrel of your Spoolmatic 15, 30A, or XR gun and slide this 6.812-inch replacement in. It's an essential consumable for any fabricator working with aluminum signage, trailers, or boat repairs.
