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

Restore Smooth Performance to Your MIG Gun

Is your wire stuttering? Are you experiencing burn-back or erratic arcs? The culprit is often hidden inside your cable. The ESAB PSF Steel Liner (0366549884) is the factory-original replacement you need to get your ESAB PSF MIG gun running like new again. As a welder, you know that the liner is the backbone of your wire delivery system. It guides the wire from the drive rolls all the way to the contact tip. When it gets dirty or worn, it creates drag that frustrates even the most experienced operators. This high-quality steel liner is designed to eliminate those headaches and provide the smooth, consistent feed you need to lay down perfect beads.

Designed for 0.035" (0.9mm) Wire

Precision matters in welding. This liner is sized specifically for 0.9mm (0.035") welding wire, which is one of the most versatile and commonly used diameters in the industry. The tight tolerance between the liner ID and the wire ensures that the current transfer is stable and that the wire doesn't buckle or "birdnest" at the drive rolls. The steel construction is robust and designed specifically for use with mild steel solid wires. (Note: If you are welding aluminum, you would typically require a Teflon or polymer liner; this steel liner is strictly for hard wires).

Easy Installation for 3M Torches

This liner comes pre-cut and ready for 3-meter (10 ft) ESAB PSF series torches. There is no need to struggle with "universal" liners that never seem to fit quite right. This is a genuine ESAB part, meaning the fittings and length are matched exactly to your gun's specifications. Installation is quick: simply remove the old liner, blow out the cable assembly with compressed air to remove any metal shavings or dust, and slide the new liner in. It’s a five-minute job that can save you hours of frustration and rework.

Why Choose Genuine ESAB?

Your welding equipment is an investment, and using genuine parts protects that investment. ESAB's engineering ensures that the spiral winding of the liner offers the right balance of flexibility and stiffness. This prevents the liner from collapsing when the cable is bent during tight positional welding. Don't let a cheap, worn-out liner compromise your weld quality. Upgrade to a fresh ESAB PSF Steel Liner and experience the difference in arc stability and wire control immediately.
