0366549884 - ESAB PSF Series Steel MIG Liner 0.9mm 3M

Reliable Wire Feeding for Industrial Applications

The ESAB PSF Steel Liner (0366549884) is a critical component designed to maintain the efficiency and reliability of your ESAB PSF series MIG torches. In industrial welding environments, the consistency of wire delivery is paramount to achieving high-quality welds and maintaining productivity. Over time, liners can become clogged with debris, kinked, or worn down by the constant friction of the welding wire. This degradation leads to erratic feeding, arc instability, and increased downtime for troubleshooting. Replacing your liner with a genuine ESAB part ensures that your equipment continues to operate at peak performance levels.

Optimized for Steel Wire

This specific liner is manufactured from high-grade steel, making it the ideal choice for feeding solid mild steel wires. The spiral-wound construction provides the necessary flexibility to maneuver the torch cable while maintaining a rigid enough internal structure to support the wire column. It is specifically engineered for 0.9mm (0.035 inch) diameter wires, a standard size for a wide range of fabrication tasks. Using the correct size liner is essential; a liner that is too large can cause the wire to snake inside, leading to poor contact tip life and unstable arcs, while a liner that is too small will cause excessive drag.

Perfect Fit for PSF Torches

Designed for 3-meter (approximately 10-foot) cable assemblies, this liner is a direct replacement for the original equipment found in ESAB PSF torches. The installation process is straightforward, allowing maintenance teams to quickly swap out worn components and get welding stations back online. By using genuine ESAB parts, you eliminate the guesswork associated with universal aftermarket liners that may require trimming or modification. This liner ensures a seamless path from the wire feeder to the contact tip, minimizing friction and maximizing the lifespan of your consumables.

Maintenance and Durability

Regular inspection and replacement of the gun liner are best practices in any welding operation. The ESAB PSF Steel Liner is built to withstand the rigors of daily use, but like all consumables, it is a wear item. Keeping a stock of these liners ensures that your production schedule is never interrupted by preventable feeding issues. Whether you are working in automotive repair, light fabrication, or general manufacturing, this steel liner provides the durability and smooth feeding characteristics required for consistent, high-quality welds.
