0366550883 - ESAB PSF Aluminum MIG Liner 0.8mm x 4.5m

Smooth Aluminum Feeding for ESAB PSF Torches

If you are welding aluminum with an ESAB PSF torch, you know that wire feeding is often the biggest headache. Aluminum wire is soft, pliable, and prone to buckling—or "bird-nesting"—at the slightest resistance. The ESAB 0366550883 Liner is your first line of defense against these frustrations. Specifically designed for 0.8mm (0.030") aluminum wire, this liner replaces the standard steel coil liner in your gun to provide a smooth, slippery path for the wire to travel from the feeder to the contact tip.

Why You Need a Dedicated Aluminum Liner

Using a steel liner for aluminum is a recipe for disaster. The rough texture of a steel spiral liner scrapes the soft aluminum, creating tiny shavings that eventually clog the liner and the contact tip. This friction causes the wire to stick and slip, resulting in an unstable arc and burn-backs. This ESAB liner uses a low-friction polymer material that allows the wire to glide effortlessly, ensuring a consistent wire speed and a stable, high-quality weld. It is the single most effective upgrade you can make to improve your aluminum MIG welding experience.

Installation and Fitment

This liner comes in a 4.5-meter length, which is plenty long enough for most standard ESAB PSF gun cables. When installing, lay your torch cable out flat and straight on the floor. Remove the old liner and slide this new one in gently. Once it hits the front of the gun, you will likely need to trim the back end to fit your specific wire feeder connection perfectly. A sharp liner cutter or razor blade is recommended to ensure a clean cut without crushing the tube. Whether you are working on a boat, a trailer, or precision aluminum fabrication, this genuine ESAB part restores your torch to factory performance levels.
