KP44-564-15 - Lincoln Magnum PRO Liner for 1/16-5/64 Wire, 15ft

Precision Wire Feeding for Heavy-Duty Applications

The Lincoln Electric KP44-564-15 Cable Liner is a critical component designed to maintain the integrity and efficiency of your welding operations. Engineered specifically for the Magnum PRO series, this liner is compatible with both Semi-Automatic Guns and Robotic Torches, ensuring versatility across manual and automated production lines. The liner is manufactured to accommodate heavy-gauge welding wires with diameters ranging from 1/16 inch (1.6 mm) to 5/64 inch (2.0 mm). This specific diameter range is typically utilized in heavy fabrication, structural steel, and industrial manufacturing where high deposition rates are required. Using a liner that is correctly matched to the wire diameter is essential for preventing feed issues; a liner that is too small will cause binding, while one that is too large can lead to erratic arc wandering.

With a total length of 15 feet (4.6 meters), this liner is suited for standard length MIG gun cable assemblies, providing ample reach for welding around large workpieces. The construction features high-grade spiral-wound steel, which offers the necessary flexibility to navigate the curvature of the cable while maintaining a rigid internal structure to support the wire. This balance reduces the coefficient of friction between the wire and the liner wall, ensuring a smooth, consistent feed speed. Consistent feeding is paramount in achieving high-quality welds, as fluctuations can lead to defects such as porosity, burn-back, or uneven bead profiles.

As a genuine Lincoln Electric OEM part, the KP44-564-15 guarantees a perfect fit within the Magnum PRO backend and contact tip adapter systems. Proper installation of the liner is crucial for gas shielding efficiency and electrical conductivity. The liner acts as the conduit that guides the electrode from the wire feeder drive rolls through to the contact tip. Over time, liners can accumulate metal shavings, lubricant, and shop dust, which increases drag. Regular replacement with this specific SKU ensures that your equipment operates at peak performance parameters, protecting your investment in the Magnum PRO system and reducing unscheduled maintenance downtime.
