KP44-564-25 - Lincoln Magnum PRO MIG Liner 1/16-5/64 Wire 25ft

High-Performance Conduit for Heavy Fabrication

The Lincoln Electric KP44-564-25 Cable Liner is a critical component for industrial welders utilizing the Magnum PRO platform for heavy-duty applications. In high-amperage welding scenarios using wires between 1/16" and 5/64" (1.6-2.0 mm), the integrity of the liner dictates the consistency of the wire feed speed (WFS). Any kink, debris accumulation, or internal wear in the liner immediately translates to arc instability, burn-backs, and increased spatter. This OEM liner is manufactured to precise tolerances to mitigate these issues over long distances.

Optimized for 25-Foot Assemblies

Feeding large diameter wire over 25 feet (7.6 meters) presents significant mechanical challenges due to friction and column strength limitations of the filler metal. The KP44-564-25 is designed with the appropriate internal clearance to support 1/16" to 5/64" wires without allowing excessive play that could lead to buckling inside the cable. This balance is vital for maintaining a stable arc in both semi-automatic and robotic applications where consistent deposition rates are non-negotiable.

Magnum PRO Compatibility

This liner is specifically engineered for the Magnum PRO ecosystem, including:

• Magnum PRO Semi-Auto MIG Guns
• Magnum PRO Robotic Torches

The Magnum PRO series is renowned for its durability and cooling efficiency. To maintain these characteristics, the liner must seat correctly in the power pin and the diffuser. The KP44-564-25 ensures a gas-tight seal and proper electrical isolation where necessary, preventing gas leakage or shorting that can occur with ill-fitting aftermarket alternatives.

Maintenance and Installation

Regular liner replacement is a cornerstone of preventive maintenance in MIG welding. For shops running heavy flux-cored or solid wires, liner wear is accelerated. When installing the KP44-564-25, ensure the cable is laid out straight to prevent cutting errors. A sharp, clean cut at the correct stick-out length is crucial to prevent gaps between the liner and the contact tip, which is a common cause of wire shaving and erratic feeding.
