Lincoln LN-9 Drive Roll Kit .030-.035 Solid Wire

Optimize Your LN-9 Feeder with Genuine Lincoln Parts

The Lincoln Electric KP502-035 is a specialized Drive Roll and Guide Tube Kit engineered for the LN-9 series of wire feeders. This kit is strictly configured for feeding solid MIG wire with diameters of 0.030 inches to 0.035 inches. Using the correct drive roll geometry is paramount in MIG welding; incorrect rolls can crush the wire, leading to flaking copper coating and liner clogs, or fail to grip adequately, causing irregular arc characteristics. This kit features smooth groove rolls designed to grip solid wire firmly yet gently, ensuring a constant feed rate that is crucial for automated or semi-automatic welding processes.

Included in the package are the drive rolls and the corresponding guide tubes. The guide tubes are essential for bridging the gap between the inlet and the drive rolls, and from the drive rolls to the gun receiver, preventing the wire from buckling under compression. This is particularly important when pushing smaller diameter wires like .030" which are more prone to kinking. By replacing both the rolls and the guides simultaneously, you restore the feeder's wire path to factory specifications.

Maintenance of your wire feeder is often overlooked until a failure occurs. Regular inspection of drive rolls for wear—indicated by a groove that has become too deep or lost its edge—is recommended. The KP502-035 offers a direct replacement solution that restores the traction necessary for consistent amperage and voltage control. Trust Lincoln Electric's OEM quality to deliver the performance your welding procedures demand.
