KP502-1/16C - Lincoln Electric KP502-1/16C Drive Roll & Guide Tube Kit for LN-8/LN-9

Optimize Wire Feeding with Lincoln KP502-1/16C Drive Rolls

Achieving a stable and consistent welding arc starts with the wire delivery system. The Lincoln Electric KP502-1/16C Drive Roll Kit is precision-engineered to facilitate the feeding of 1/16-inch (1.6 mm) cored wire through LN-8 and LN-9 wire feeders. Cored wires, including flux-cored and metal-cored varieties, have a tubular construction that makes them more susceptible to crushing than solid wires. If a drive roll applies too much pressure or lacks the appropriate groove geometry, the wire can deform, leading to poor electrical contact in the contact tip and erratic feeding. This kit addresses those challenges with drive rolls designed specifically to grip cored wire securely while maintaining its structural integrity.

The KP502-1/16C kit is a 2-roll kit solution that includes not just the drive roll, but also the corresponding guide tube. The guide tube plays a pivotal role in the feeding system by bridging the gap between the inlet and the drive rolls, and from the drive rolls to the gun receiver. This ensures that the relatively flexible cored wire does not buckle or "bird-nest" under the pushing force of the drive motor. By pairing the drive roll with the correct guide tube, Lincoln Electric ensures a seamless path for the wire, significantly reducing the likelihood of feed jams and liner clogging.

Durability is a hallmark of Lincoln Electric components. The drive rolls in this kit are manufactured from high-grade hardened steel to resist wear from the abrasive nature of welding wires and the industrial environment. This longevity translates to lower operational costs and fewer interruptions for maintenance. For shops running LN-8 or LN-9 systems, keeping a spare KP502-1/16C kit on hand is a best practice to ensure that production schedules are not impacted by wear-and-tear on consumable feeder parts.

Welders Supply is proud to offer genuine Lincoln Electric accessories like the KP502-1/16C. We recognize that the performance of your welding power source is only as good as the wire feeder's ability to deliver the consumable to the puddle. Upgrade or maintain your equipment with this specific kit to experience the difference that OEM engineering makes in high-amperage, cored wire welding applications.
