KP3544-3545-25 - Lincoln Electric Steel MIG Liner .035-.045 25ft

Reliable Wire Feeding with Lincoln Electric

The Lincoln Electric KP3544-3545-25 Steel Liner is an essential component for maintaining the efficiency and reliability of your MIG welding operations. Designed specifically for use with steel welding wires, this liner accommodates diameters ranging from .035 inches to .045 inches, covering the most common sizes used in general fabrication and industrial applications. A worn or kinked liner is often the hidden culprit behind erratic arcs and frustrating wire feed issues; replacing it with a high-quality OEM part restores your equipment's performance instantly.

What sets this particular liner apart is its substantial 25-foot length. While standard MIG guns often utilize shorter liners, this extended version is perfect for specialized long-reach assemblies or push-pull systems where distance from the feeder is required. The steel coil construction provides the necessary rigidity to prevent collapsing while remaining flexible enough to maneuver around the shop floor. By maintaining a consistent internal diameter, it guides the welding wire smoothly from the drive rolls to the contact tip, minimizing drag and preventing the "chatter" that can ruin a weld bead.

Maintenance professionals understand that the liner is a consumable item that requires regular inspection. Over time, copper dust, dirt, and metal shavings can accumulate inside the spiral, increasing friction. Installing the KP3544-3545-25 is a straightforward process that ensures your welding parameters remain stable. Whether you are welding structural steel, performing automotive repairs, or working on heavy machinery, trusting genuine Lincoln Electric parts ensures that your equipment operates as engineered. This liner is packaged individually and is ready for immediate installation to get you back to welding with confidence.

At Josef Gas, we recommend keeping spare liners on hand to minimize downtime. When wire feeding becomes difficult despite checking contact tips and drive rolls, a fresh liner is often the solution. Invest in the longevity of your torch and the quality of your welds with this durable steel liner.
