KP1885-1 - Lincoln Electric Knurled Drive Roll for MAXsa 22/29 Feeders

Technical Specifications and Compatibility

The Lincoln Electric KP1885-1 is a specialized knurled drive roll designed for the precise feeding of large diameter welding wires, specifically within the range of 3/32 inch (2.4 mm) to 7/32 inch (5.6 mm). This component is an integral part of the wire feeding mechanism in high-amperage Submerged Arc Welding (SAW) setups. The roll features a knurled groove geometry that bites into the wire surface, providing the necessary driving force to overcome friction in the conduit and torch assembly without deforming the wire excessively.

System Compatibility: This drive roll is manufactured for direct compatibility with Lincoln Electric's heavy-duty wire feeders, including the MAXsa™ 22 and MAXsa™ 29 units. It is also specified for use with the Power Wave® AC/DC 1000 welding system, often utilized in tandem for automated multi-arc applications. The precise machining of the KP1885-1 ensures correct alignment with the wire guide and pressure arm, minimizing wear on the feeder motor and preventing wire shaving accumulation.

Operational Performance: In submerged arc applications, consistent wire stick-out and feed speed are paramount for arc stability and bead profile control. Smooth V-groove rolls may struggle to generate sufficient traction on the heavy, stiff wires used in SAW. The knurled design of the KP1885-1 mitigates this issue, delivering positive traction even under high-tension feeding conditions. This part is supplied as a single unit; operators should verify the number of driven rolls required for their specific feeder configuration before ordering.
