KP45-3545-25 - Lincoln Electric Magnum PRO Cable Liner .035-.045 25ft

Reliable Wire Feeding for Magnum PRO Systems

The Lincoln Electric KP45-3545-25 Cable Liner is a critical component designed to maintain the performance and reliability of your MIG welding operations. Engineered specifically for use with Magnum® PRO Semi-Automatic MIG Guns and Magnum® PRO Robotic Torches, this liner ensures that welding wire travels smoothly from the feeder to the contact tip. With a length of 25 feet (7.6 meters), it is perfectly suited for extended cable assemblies often found in large-scale fabrication environments or robotic cells where reach is paramount.

This liner is optimized for wire diameters ranging from .035 inches to .045 inches (0.9 mm to 1.2 mm), covering the most common sizes used in industrial manufacturing. A compromised or worn liner is a leading cause of wire feeding issues, such as bird-nesting, erratic arc starts, and burn-backs. By replacing your liner with this genuine Lincoln Electric part, you restore the mechanical integrity of the wire feed path, ensuring consistent electrical contact and arc stability. The spiral-wound steel construction provides the necessary flexibility to navigate the cable's curvature while maintaining enough rigidity to prevent kinking.

Installation is straightforward, adhering to standard maintenance procedures for Magnum PRO equipment. The liner is supplied at the full 25-foot length and is intended to be trimmed to the exact requirements of your specific gun assembly during installation. This versatility allows it to serve as a replacement for various cable lengths up to 25 feet, simplifying inventory management for shops with multiple gun configurations. Whether utilized in manual semi-automatic welding or high-precision robotic applications, the KP45-3545-25 delivers the durability expected from Lincoln Electric consumables.
