KP655-3/32 - Lincoln Electric KP655-3/32 Drive Roll & Guide Tube Kit for LN-9/Synergic 7F

Lincoln Electric KP655-3/32 Drive Roll Kit Overview

The Lincoln Electric KP655-3/32 Drive Roll Kit is a critical component designed to maintain the efficiency and precision of your industrial wire feeding systems. Engineered specifically for heavy-duty applications, this kit is tailored to handle wire diameters ranging from .068 inches to 3/32 inches (1.7 mm to 2.4 mm). It is versatile enough to support both cored and solid welding wires, making it an essential inventory item for shops that switch between different welding processes or wire types. The kit is manufactured to the high standards of Lincoln Electric, ensuring seamless compatibility and long-lasting performance.

This specific drive roll kit is designed for use with the LN-9, LN-9 GMA, and Synergic 7F and 7FH wire feeders. These feeders are often employed in high-production environments where consistency is paramount. The KP655-3/32 utilizes a 4-roll configuration. Four-roll systems are superior to two-roll systems for heavier wires or softer cored wires because they provide twice the traction surface area. This allows for positive feeding force without the need for excessive drive roll pressure, which can deform cored wires or cause shaving on solid wires. By maintaining the integrity of the wire shape, the contact tip life is extended, and arc stability is improved.

In addition to the drive rolls themselves, the kit includes the necessary guide tubes. Guide tubes are essential for directing the wire accurately into the drive rolls and then into the gun liner. Worn guide tubes can cause wire misalignment, leading to bird-nesting or erratic feeding. By replacing the guide tubes simultaneously with the drive rolls, operators ensure a completely refreshed wire path that minimizes friction and drag. This holistic approach to maintenance reduces unscheduled downtime and keeps production lines moving efficiently.

Investing in genuine Lincoln Electric parts like the KP655-3/32 ensures that your equipment operates within its factory specifications. Generic or mismatched drive rolls can lead to slippage, inconsistent wire stick-out, and ultimately, poor weld quality. Whether you are welding structural steel with flux-cored wire or fabricating heavy machinery with solid wire, this drive roll kit provides the reliability required for professional results.
