0366549891 - ESAB PSF Steel MIG Liner 1.6mm x 4.5m

Restore Smooth Wire Feeding with the ESAB PSF Steel Liner

Is your MIG gun sputtering, or does the wire feel like it's dragging? It might be time to replace your liner. The ESAB PSF Steel Liner (0366549891) is the perfect solution for welders using ESAB PSF series torches who need to get back to laying down smooth, consistent beads. The liner is the backbone of your wire delivery system; over time, it fills with metal shavings, dust, and debris, or develops kinks that create friction. This friction results in an unstable arc, frustrating wire chatter, and the dreaded "birdnest" at the drive rolls. Installing a fresh liner is one of the cheapest and most effective ways to tune up your welder.

Designed specifically for 1.6mm (1/16") wire, this steel liner offers the rigidity and durability needed for pushing heavier gauge wires through the cable assembly. At 4.5 meters long, it is ready for 15-foot torch leads but can easily be trimmed to fit shorter cables if necessary. The steel spiral design provides excellent flexibility while maintaining a circular cross-section to prevent the wire from binding, even when the cable is looped or bent during positional welding.

Installation is straightforward for anyone familiar with MIG gun maintenance. Simply remove the nozzle and contact tip, disconnect the gun from the feeder, pull out the old liner, and slide this new one in. A sharp pair of side cutters is all you need to trim the excess. Don't let a $20 part ruin a day's worth of welding. Keep your ESAB PSF gun running like new with this genuine replacement liner. Whether you are in the shop or out in the field, reliable wire feeding is non-negotiable for quality welds.
