KP653-035S - Lincoln LN-25 .035 Solid Wire Drive Roll & Guide Kit

Precision Drive Roll Kit for .035 Solid Wire Applications

The Lincoln Electric KP653-035S is a specialized Drive Roll and Guide Tube Kit tailored for the LN-25 series of wire feeders. In MIG and MAG welding, the stability of the arc is directly tied to the consistency of the wire feed speed. This kit is precision-machined to handle 0.035-inch (0.9 mm) solid wire, providing the exact groove geometry required to grip the wire firmly without causing deformation or shaving, which can clog liners and contact tips.

Optimized for Solid Wire
Solid wire requires a specific drive roll profile—typically a V-groove—to maximize traction while maintaining the wire's round shape. The KP653-035S is manufactured to these exacting standards. Unlike knurled rolls used for flux-cored wires that bite into the metal, these rolls rely on friction and precise fitment. This ensures that the copper coating on your solid wire remains intact, promoting better electrical conductivity at the contact tip and reducing the accumulation of debris in the gun liner.

Complete Feed Path Solution
The inclusion of the guide tube is a critical aspect of this kit. The guide tube bridges the gap between the inlet and the drive rolls, supporting the wire and preventing it from buckling under the compression of the drive system. This is particularly important in industrial environments where the feeder may be moved frequently or positioned at awkward angles. A worn guide tube can lead to wire misalignment, causing increased friction and erratic feeding.

Compatibility and Performance
Designed for the robust LN-25 wire feeder, this kit supports the 2-roll drive mechanism inherent to that model. It is an OEM replacement part, guaranteeing perfect fitment and alignment with the feeder's motor shaft and tensioning arm. By using genuine Lincoln Electric consumables, professional welders ensure that their equipment operates within its specified parameters, delivering the high-quality welds expected in structural, pipeline, and heavy fabrication applications.
