0700300505 - ESAB Yellow PTFE Liner for 1.2mm-1.6mm Aluminum Wire

Smooth Feeding for Aluminum Welding

If you have ever wrestled with aluminum MIG wire bird-nesting at the drive rolls or stuttering at the tip, you know the frustration of a bad liner. The ESAB Yellow PTFE Liner (0700300505) is your solution for smooth, headache-free welding with soft wires. Designed specifically for 0.045" (1.2mm) to 1/16" (1.6mm) aluminum and stainless steel wire, this Teflon liner replaces your standard steel coil liner to provide a slick, friction-free path for the wire to travel.

Why use PTFE? Steel liners act like a file against soft aluminum wire, shaving off tiny flakes that clog up your gun and cause erratic feeding. This ESAB Teflon liner is smooth as glass inside, allowing the wire to glide effortlessly from your machine to the puddle. The yellow jacket makes it easy to identify in your toolbox, so you never grab the wrong size by mistake. Whether you are fabricating aluminum boat hulls, fixing a trailer, or doing precision stainless work, swapping to this liner is the single best upgrade you can make to your MIG gun setup.

Installation is straightforward. Simply remove your old liner, slide this new PTFE liner in, and trim it to the correct length for your specific torch cable. It is built to withstand the rigors of the shop environment while protecting your delicate wire from kinks and bends. Don't let feed problems ruin your welds or your day—equip your ESAB torch with the correct liner for the job and experience the difference that proper consumables make. This liner is compatible with many standard ESAB MIG guns and is essential for anyone serious about running aluminum.
