0700300321 - ESAB PA Liner 1.0-1.2mm 3.5m for Aluminum Wire

Stop Fighting Your Wire Feed

If you are welding aluminum, you know the headache of bird-nesting and erratic feeding. Often, the culprit is simply the wrong liner. The ESAB PA Liner (0700300321) is the fix you need. This isn't a standard steel coil; it's a smooth Polyamide tube designed to let soft wires like aluminum and stainless steel slide through your torch cable without snagging or shaving.

This liner is sized for 1.0mm to 1.2mm wire and comes in a 3.5-meter length, which covers most standard MIG guns. If your gun is shorter, you can easily trim the liner to the perfect length during installation. Switching to a PA liner is the single most effective change you can make when setting up your rig for aluminum work. It drastically lowers friction, meaning your drive rolls don't have to work as hard, and your wire comes out straight and steady.

Don't let a cheap or worn-out liner ruin your welds or waste your expensive aluminum wire. Swap in this genuine ESAB replacement part to keep your operation running smoothly. Whether you are in a production shop or a garage, reliable feeding means better beads and less frustration.
