KP1505-1/16 - Lincoln KP1505-1/16C Knurled Drive Roll Kit for 4-Roll Feeders

Precision Feeding for Heavy-Duty Fabrication

The Lincoln Electric KP1505-1/16C Drive Roll Kit is an essential component for industrial welding operations utilizing 1/16-inch (1.6mm) cored wires. Engineered to meet the rigorous demands of heavy fabrication, this kit is designed for 4-roll wire drive systems found in premium Lincoln feeders such as the LN-25 PRO, LF-72, and select Power MIG models. The kit includes four matched drive rolls, ensuring that feeding force is distributed evenly across the wire surface, minimizing deformation while maximizing traction.

Feeding flux-cored or metal-cored wire presents unique challenges due to the tubular nature of the consumable. Smooth V-groove rolls often require excessive tension to grip the wire, which can crush the shell and disrupt the flux core, leading to poor arc characteristics. The KP1505-1/16C features a specialized knurled groove design. The teeth of the knurl bite gently into the wire's surface, providing positive drive force without the need for crushing pressure. This design is critical for maintaining consistent wire stick-out and arc stability, particularly in long-conduit runs common in shipbuilding and structural steel erection.

Durability is paramount in industrial environments. These drive rolls are manufactured from high-grade, heat-treated steel to withstand the abrasive nature of cored wires and the mechanical stress of continuous operation. By using genuine OEM Lincoln Electric parts, operators ensure seamless compatibility with their equipment's wire guide tubes and tensioning mechanisms. This kit is a vital investment for maintaining the reliability of your wire feeding system, reducing downtime caused by feed failures, and ensuring high-quality weld deposition.
