0366549882 - ESAB PSF Steel Liner 0.6-0.8mm for 3m MIG Guns

Smooth Wire Feeding for Precision Welds

Is your wire stuttering or feeding unevenly? It might be time to replace your gun liner. The ESAB PSF Steel Liner (0366549882) is the factory-original replacement for 3-meter (10 ft) ESAB PSF MIG guns running light-gauge steel wire. Designed to handle 0.023" to 0.030" (0.6mm - 0.8mm) wire, this liner ensures that your consumable path is clear, smooth, and friction-free.

A degraded liner is one of the most common causes of frustration in MIG welding. As the liner wears, it accumulates debris and can become rough inside, causing the wire to drag. This results in a wandering arc and poor weld bead appearance. This ESAB steel liner features a durable spiral design that resists kinking while providing a low-friction conduit for your solid steel wires. It is easy to install—simply remove the old liner from the back of the gun, insert the new one, and trim to the correct stick-out length if necessary.

Don't let a cheap or worn-out liner compromise your weld quality. Invest in genuine ESAB components to keep your PSF torch running like new. Ideal for body shops, hobbyists, and professional fabricators working with thinner gauge steel who require precise wire placement and consistent arc characteristics.
