0700200090 - ESAB Aluminum MIG Liner .023-.030 13ft PTFE

Smooth Aluminum Feeding with ESAB Teflon Liners

If you have ever tried to weld aluminum with a standard steel MIG liner, you know the frustration of "bird-nesting." The wire stops feeding, tangles up at the drive rolls, and ruins your rhythm. The solution is simple: you need to reduce friction. The ESAB 0700200090 Teflon Liner is the essential upgrade for any welder looking to run .023" or .030" aluminum wire. Because aluminum is soft and pliable, pushing it through a steel spiral liner is like trying to push a wet noodle through a straw—it just buckles. This Teflon liner provides a slick, slippery surface that allows the wire to glide effortlessly from your machine to the contact tip.

Why Teflon?
Steel liners are designed for steel wire. They are hard and abrasive. When soft aluminum slides against steel, it creates drag and can even scrape off tiny shavings of aluminum. These shavings build up and clog your gun, causing erratic feeding and burn-backs. This ESAB Teflon liner eliminates that metal-on-metal contact. It is designed specifically for the smaller diameter wires (.023-.030), giving you the precision control needed for thin-gauge aluminum work, such as automotive body repair or light fabrication.

Installation Tips
This liner comes in a 13-foot length, which is standard for most 10-12 foot torches. When installing, it is crucial to lay your torch out completely straight. Remove the old liner, slide this new Teflon liner in gently, and trim it to the correct length. Be sure to use a sharp blade to get a clean, flat cut—do not use side cutters that might pinch the plastic tube. Many welders also recommend using a brass neck liner (jump liner) at the very end of the torch if your gun supports it, to protect the Teflon from the extreme heat of the arc. Equip your rig with the ESAB 0700200090 and experience the difference a proper feed system makes.
