KP1899-3 - Lincoln Electric KP1899-3 Solid Wire Drive Roll & Guide Tube Kit (.035-.052)

Reliable Feeding for Consistent Welds

Every welder knows that a stable arc starts with smooth wire feeding. The Lincoln Electric KP1899-3 Drive Roll/Guide Tube Kit is the solution for welders using Lincoln's robust automatic wire feeding systems who demand reliability and precision. This kit is specifically tailored for use with Solid Wire and covers the essential wire diameters of .035 inches, .045 inches, and .052 inches. Whether you are setting up a Cruiser tractor for a long deck weld or maintaining an NA-3S, NA-4, or NA-5 feeder in a fabrication cell, this kit ensures your equipment is ready to perform.

One of the primary challenges in wire welding is preventing feeding issues such as slipping or birdnesting. These problems not only interrupt production but can also cause defects in the weld deposit. The KP1899-3 kit combats this by providing drive rolls with the correct groove geometry for solid wire. The V-groove design typically used for solid wire maximizes surface contact for traction while maintaining the roundness of the wire. This ensures that the wire feeds smoothly through the liner and contact tip, resulting in a consistent electrical stick-out and a stable arc.

The convenience of this kit cannot be overstated. Instead of sourcing individual rolls and tubes, the KP1899-3 provides a complete package. It includes the necessary guide tubes that are critical for aligning the wire with the drive rolls. Misaligned wire can shave metal off the wire surface, clogging liners and tips with debris. By installing the matched guide tubes included in this kit, you ensure the wire travels a straight, unobstructed path. This reduces wear on your equipment and minimizes the frequency of maintenance stops.

For shops utilizing Lincoln's industrial feeders, keeping a KP1899-3 kit on the shelf is a smart move. It allows for quick changeovers between wire sizes and ensures that when a wear component needs replacement, you have the exact factory-specified part on hand. Keep your arc on and your downtime low with this genuine Lincoln Electric drive roll kit.
