KP44-116-15-B10 - Magnum PRO MIG Gun Liner .052-1/16 in, 15 ft (10-Pack)

Technical Overview of the Lincoln Electric KP44-116-15-B10

The Lincoln Electric KP44-116-15-B10 is a specialized cable liner designed to facilitate the precise delivery of welding wire in Magnum PRO Semi-Auto and Robotic MIG guns. Engineered for wire diameters ranging from .052 inches to 1/16 inches (1.3 mm to 1.6 mm), this liner is critical for maintaining the tribological balance within the welding cable assembly. In industrial welding applications, the internal surface condition of the liner directly dictates the coefficient of friction experienced by the consumable electrode. As the liner wears or accumulates debris, feed force increases, leading to potential burn-backs or erratic arc characteristics. This component is manufactured to strict tolerances to ensure concentricity with the contact tip and proper alignment within the gun receiver.

This specific SKU is supplied as a bulk package containing ten (10) individual liners, each measuring 15 feet (4.6 meters) in length. The 15-foot length is standard for many extended-reach manual and robotic setups, providing full coverage from the wire drive rolls to the diffuser. For shorter cable assemblies, the liner is designed to be trimmed to size during installation, following standard manufacturer procedures to ensure the correct stick-out length at the gas diffuser. Proper trimming is essential to prevent gaps where the wire could buckle, a common cause of "bird-nesting" at the feeder.

Compatibility is strictly tuned for the Magnum PRO series, a line of torches known for high-amperage performance and durability. The liner material is selected to withstand the mechanical abrasion of steel and flux-cored wires while resisting kinking during cable manipulation. Regular replacement of the cable liner is a preventative maintenance requirement in any ISO-standard welding operation. By utilizing the KP44-116-15-B10, maintenance teams can ensure that the wire feeding path remains unobstructed and dimensionally accurate, thereby preserving the integrity of the welding parameters and final weld quality.
