The Lincoln Electric KP674-035S Drive Roll Kit is a critical component for maintaining the operational efficiency of specific Lincoln Electric MIG welding systems. Designed with the rigorous demands of industrial fabrication in mind, this kit is engineered to provide positive traction on solid welding wires ranging from .025 inches to .035 inches (0.6 mm to 0.9 mm) in diameter. The drive rolls feature precision-machined grooves that match the radius of solid wire, ensuring optimal grip without causing deformation or mechanical damage to the wire surface. This is essential for maintaining consistent electrical contact at the contact tip and ensuring a stable arc characteristic.
Compatibility is a key factor in drive roll selection. The KP674-035S is specifically manufactured for the wire drive mechanisms found in the Wire-Matic 255, Idealarc SP-150, Idealarc SP-250, and Idealarc SP-250-I welding systems. Using OEM-specified drive rolls is paramount for preventing feed issues such as slippage, erratic wire speeds, and birdnesting, which can lead to significant downtime and rework. The geometry of these rolls is optimized to handle the column strength of solid steel and stainless steel wires, providing the necessary push force through the liner and gun cable assembly.
In a production environment, the reliability of the wire feeding system directly correlates to weld quality and throughput. Worn or incorrect drive rolls are a common source of arc instability and burn-back. By utilizing the KP674-035S, operators can ensure that their equipment operates within factory specifications. The kit includes the necessary components for a complete changeover, allowing for quick maintenance intervals and minimal disruption to workflow. Whether for light gauge sheet metal work or general structural fabrication, these drive rolls provide the mechanical consistency required for high-quality MIG welding.
Investing in genuine Lincoln Electric consumables and replacement parts guarantees that the tolerances and material hardness meet the original design requirements of the welding power source. This drive roll kit represents a small but vital investment in the longevity and performance of your Lincoln Electric welding assets.
