0366549899 - ESAB PSF Steel MIG Liner for 2.4mm Wire - 4.5m Length

Optimize Your ESAB PSF Torch Performance

The ESAB PSF Liner Steel 2.4mm 4.5m (SKU: 0366549899) is a critical component designed to maintain the efficiency and reliability of your welding operations. Specifically engineered for the renowned ESAB PSF series of MIG guns, this steel liner provides the structural integrity and low-friction path required for feeding heavy-duty welding wires. With an internal diameter optimized for 2.4mm (approx. 3/32 inch) wire, it is ideal for industrial applications where high deposition rates and thicker filler metals are standard.

Over time, MIG liners accumulate dust, metal shavings, and drawing lubricants from the welding wire. This debris creates friction, leading to erratic wire feeding, arc instability, and the frustrating "burn-back" phenomenon. Replacing your liner regularly with a genuine ESAB steel liner ensures that your wire moves smoothly from the feeder to the contact tip. This specific model features a 4.5-meter length, making it a perfect fit for standard 15-foot torch assemblies, ensuring full coverage from the back end of the gun to the gas diffuser.

Constructed from high-grade spiral-wound steel, this liner offers excellent flexibility without collapsing, allowing the torch cable to bend and maneuver around workpieces while maintaining a consistent internal diameter. The steel material is specifically chosen for use with carbon steel and flux-cored wires, providing the hardness necessary to resist the abrasive nature of these wires. For welders relying on ESAB's PSF torches for heavy fabrication, structural steel, or manufacturing, this replacement liner is an indispensable spare part to keep on hand.

Installation is straightforward, designed to seat correctly within the PSF torch body and power pin. By maintaining a clean and unkinked path for your welding wire, you significantly reduce the load on your wire feeder's drive rolls and motor, prolonging the life of your entire welding system. Invest in genuine ESAB parts to ensure compatibility and performance.
