KP1695-3/64A - Lincoln KP1695-3/64A Aluminum Drive Roll Kit - 3/64 Inch U-Groove

Precision Aluminum Feeding Solutions

The Lincoln Electric KP1695-3/64A Drive Roll Kit is a specialized accessory designed to address the unique challenges of feeding soft aluminum welding wire. Unlike steel wires, aluminum is prone to deformation, crushing, and buckling when subjected to the pressure of standard V-groove rollers. This kit replaces standard components with precision-engineered U-Groove drive rolls that cradle the 3/64-inch (1.2 mm) wire, providing positive traction without altering the wire's cross-sectional shape. This preservation of the wire geometry is critical for maintaining consistent electrical contact at the contact tip and ensuring a stable welding arc.

Engineered for Lincoln Electric's robust 2-roll wire feeder systems, such as the LN-25X, LN-25 PRO, and various Power MIG models, this kit is a fundamental requirement for any fabrication shop transitioning to aluminum projects. The kit is not merely a set of wheels; it includes a specialized split wire guide. This guide is essential for bridging the gap between the drive rolls and the gun liner, offering continuous support to the flexible aluminum wire. By minimizing unsupported length, the guide effectively eliminates "bird-nesting"—the frustrating tangling of wire at the feeder inlet that causes significant downtime.

Industrial reliability is at the core of the KP1695-3/64A. The components are manufactured to tight tolerances to ensure perfect alignment within the feeder mechanism. Whether you are operating a portable wire feeder in the field or a stationary shop welder, installing this kit ensures that your equipment delivers the smooth, uninterrupted wire feed necessary for high-quality aluminum welds. It represents a critical investment in process stability and efficiency for professional welders.
