KP3544-3545-35 - Lincoln Electric Steel MIG Liner .035-.045 35ft

High-Performance Steel Liner for Long-Distance MIG Welding

Maximize the performance of your long-reach welding systems with the Lincoln Electric KP3544-3545-35 Steel Liner. Engineered for precision and durability, this liner is an essential component for welders operating with cable assemblies up to 35 feet in length. In MIG welding, the liner acts as the backbone of the wire feeding system, guiding the electrode from the feeder to the contact tip. For extended setups, the quality of the liner becomes even more critical, as increased length introduces more potential for friction and drag. Lincoln Electric has designed this liner to minimize these issues, ensuring that your wire delivery remains smooth and uninterrupted.

This specific liner is tailored for steel wires with diameters between .035 and .045 inches, covering the most common range for general fabrication and structural work. The steel coil construction is robust enough to withstand the abrasive nature of steel wire while maintaining the flexibility needed for maneuvering the gun. Unlike generic replacements, this genuine Lincoln part is manufactured to tight tolerances, ensuring that the internal diameter perfectly matches the specified wire sizes. This precise fit reduces wire play inside the liner, which improves arc stability and bead placement accuracy.

Key Technical Benefits:

• Reduced Friction: The smooth internal finish minimizes drag, which is critical for 35-foot runs where feed motor strain can be a concern.
• Kink Resistance: High-tensile steel winding prevents the liner from collapsing when the cable is bent or coiled.
• Compatibility: Designed for seamless integration with compatible Lincoln Magnum PRO and similar gun assemblies.

Welders Supply recommends checking your liner condition regularly, especially in long-cable applications. Signs of a worn liner include erratic feeding, burn-back, or the wire sticking in the tip. Replacing your old liner with the KP3544-3545-35 is a cost-effective maintenance step that can dramatically improve weld quality. Whether you are running solid steel wire or flux-cored wire within the specified diameter range, this liner provides the consistent conduit necessary for professional results. Ensure your equipment is ready for the toughest jobs with genuine Lincoln Electric consumables.
