KP1696-1 - Lincoln Electric KP1696-1 V-Groove Drive Roll Kit for .035/.045 Solid Wire

Technical Overview of the Lincoln Electric KP1696-1

The Lincoln Electric KP1696-1 is a precision-engineered drive roll and guide tube kit designed to facilitate the reliable feeding of solid welding wires in .035-inch (0.9 mm) and .045-inch (1.1 mm) diameters. This kit is specifically manufactured for Lincoln Electric wire feeders utilizing a 2-roll drive system, including the industry-standard LN-25, LN-25X, LN-25 PRO, Power Feed, and Active8X series. The components are machined to tight tolerances to ensure consistent wire alignment and traction, which is critical for maintaining stable arc characteristics during MIG (GMAW) operations.

The drive rolls feature a V-Groove geometry, which is the standard profile for feeding solid mild steel and stainless steel wires. Unlike knurled rolls which bite into the wire, or U-groove rolls designed for soft aluminum, the V-Groove provides necessary friction for feeding without deforming the wire's cross-section or flaking off copper coating. This preservation of wire integrity reduces the accumulation of debris in the liner and contact tip, thereby extending consumable life and reducing downtime.

Included in the KP1696-1 kit is a split wire guide. This component is essential for bridging the gap between the inlet and the drive rolls, supporting the wire as it enters the drive mechanism. By minimizing unsupported wire length, the split guide effectively prevents "bird nesting"—the buckling of wire typically caused by feed restrictions or liner blockages. This kit represents a direct OEM replacement part, ensuring perfect fitment and adherence to Lincoln Electric's performance specifications for industrial wire feeding equipment.
