KP1507-035A - Lincoln Power Feed Aluminum Drive Roll Kit .035

Precision Aluminum Wire Feeding Solution

The Lincoln Electric KP1507-035A Drive Roll Kit is a specialized accessory engineered to address the unique tribological and mechanical challenges associated with feeding small-diameter aluminum welding wire. Designed specifically for .035-inch (0.9 mm) aluminum consumables, this kit is an essential component for high-precision industrial fabrication environments utilizing Lincoln Electric Power Feed® wire feeder systems. Unlike steel wires, aluminum possesses a lower column strength and is highly susceptible to deformation, shaving, and "bird-nesting" if subjected to excessive compression or friction within the feeding path. This kit mitigates these issues through a purpose-built design that prioritizes smooth, low-friction delivery.

The kit features a 4-roll configuration, which is critical for distributing the feeding force over a larger surface area compared to 2-roll systems. This distribution allows for positive traction without the need for excessive drive roll tension that could deform the soft aluminum wire. The inclusion of matched guide tubes ensures that the wire path remains strictly aligned from the inlet to the gun receiver bushing, minimizing the unsupported length of the wire where buckling typically occurs. By maintaining strict tolerances between the drive rolls and the guide tubes, the KP1507-035A ensures consistent arc stability and reduces the frequency of feed-related downtime.

Fabricators operating in sectors such as marine construction, automotive manufacturing, and aerospace benefit significantly from the reliability provided by this kit. The drive rolls are manufactured to precise specifications to accommodate the thermal expansion and surface characteristics of aluminum alloys. When installed in compatible Power Feed® units, this kit transforms the wire feeding mechanism into a system capable of sustaining high-duty cycle operations required in heavy fabrication and automated robotics applications. The kit includes all necessary components for a complete changeover, ensuring that the feeder is optimized for aluminum processing immediately upon installation.
