The ESAB PSF Liner Steel 0.9mm 4.5m (SKU: 0366549885) is a critical component for maintaining the performance of your ESAB PSF series MIG welding guns. Designed specifically for use with solid steel welding wires, this liner ensures that the filler metal travels smoothly from the drive rolls to the contact tip without interruption or excessive friction. Over time, MIG liners can become clogged with shop dust, metal shavings, and lubricant residue, or they can develop kinks that impede wire travel. Replacing your liner regularly is one of the most effective ways to troubleshoot erratic wire feeding and unstable arcs.
This specific liner is engineered with a precise internal diameter to accommodate 0.9mm (0.035") welding wire, a standard size for general fabrication and automotive work. The liner is constructed from high-grade spiral-wound steel, providing the necessary rigidity to prevent collapsing while remaining flexible enough to navigate the bends of the torch cable. With a total length of 4.5 meters (approximately 15 feet), it is suitable for standard length PSF torches and can be trimmed to fit shorter cable assemblies if necessary.
Using genuine ESAB parts like the 0366549885 liner guarantees compatibility with the PSF gas nozzle and diffuser system. A well-functioning liner minimizes the strain on your wire feeder motor and reduces the likelihood of "birdnesting" at the drive rolls. For optimal welding results, it is recommended to blow out the liner with compressed air during wire changes and replace the liner entirely if feed resistance increases noticeably.
