0700025315 - ESAB PA Bronze MIG Liner for 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 importance of a good liner. The ESAB PA Bronze Liner (0700025315) is built to solve exactly those problems. Designed specifically for thicker 1.6mm (1/16") wires, this liner uses a slick Polyamide (PA) material that lets soft aluminum wire glide through your torch cable without snagging or shaving. Unlike steel liners that can scratch soft wires and cause clogging, this plastic liner keeps your wire clean and your feed speed consistent.

Why the Bronze?
Pure plastic liners are great for feeding, but they can melt if they get too close to the heat of the weld puddle. That is why ESAB adds a bronze section to this liner. The bronze handles the high heat at the neck of the gun, ensuring your liner doesn't deform right where the action happens. It gives you the best of both worlds: the smooth, low-friction feed of plastic and the durability of metal.

Installation & Compatibility
This liner is a genuine ESAB replacement part, ensuring a perfect fit for your compatible ESAB MIG guns (check your manual for PSF or MXL series compatibility). Installing it is straightforward: simply remove your old steel liner, blow out the cable to remove any debris, and slide this new PA Bronze liner in. Trimming it to the correct length is crucial—ensure it sits flush against the back of the contact tip or gas diffuser to prevent wire wandering. Whether you are fabricating boat hulls, trailers, or custom aluminum parts, this liner is the upgrade your torch needs for reliable performance.
