16201312 - Tweco 15ft Teflon Liner for .035-3/64 Aluminum Wire

Smooth Feeding for Aluminum Welding

If you have ever tried to weld aluminum with a standard steel liner, you know the nightmare: the wire stops, the drive rolls spin, and suddenly you have a bird's nest of wire tangled up at the feeder. It ruins your tip, wastes your wire, and kills your productivity. The solution is simple but essential: you need the right liner. The Tweco 1620-1312 Teflon Conduit is built to solve exactly this problem. Designed for 15-foot MIG guns, this liner replaces your standard steel coil with a smooth, slick Teflon tube that lets soft aluminum wire glide through the cable with almost zero resistance.

This liner is sized perfectly for the most common aluminum wire sizes, .035" and 3/64". Whether you are fabricating boat parts, repairing a trailer, or working on custom automotive components, consistent wire delivery is the key to a good bead. Aluminum requires a steady, fast wire speed to maintain a spray transfer or stable pulse, and any drag in the line will cause the arc to stutter. By installing this Tweco Teflon liner, you eliminate the friction points that cause those issues. It's a small upgrade that makes a massive difference in how your machine runs.

Installation is straightforward. Remove your old steel liner, slide this Teflon conduit in, and trim it to the correct length for your gun's front end. Make sure your cuts are clean and straight to prevent any snagging points. Remember, this liner is strictly for soft wires like aluminum or silicon bronze; don't run steel wire through it, or you'll slice it up. Keep a spare in your toolbox so you are always ready to switch over to aluminum jobs without fighting your equipment.
