KP1888-2 - Lincoln Electric KP1888-2 Smooth Drive Roll for NA-5S Tiny Twinarc

Precision Wire Feeding for Submerged Arc Systems

The Lincoln Electric KP1888-2 Drive Roll is a critical component designed to ensure the smooth and reliable operation of your automated welding setups. Engineered specifically for the NA-5S welding system, this drive roll features a smooth groove geometry that is optimized for feeding solid wires without causing deformation or shaving. It is tailored for wire diameters ranging from 1/16 inch (1.6 mm) to 5/64 inch (2.0 mm), making it an essential part for specific heavy-duty fabrication tasks.

This drive roll is explicitly compatible with the Tiny Twinarc® K129 submerged arc nozzle assemblies. In submerged arc welding (SAW), consistent wire delivery is paramount to maintaining the integrity of the weld bead and ensuring proper deposition rates. The KP1888-2 provides the necessary traction to push the wire through the contact shoes effectively, even during long, continuous welding cycles typical of automated environments.

By using genuine Lincoln Electric parts like the KP1888-2, operators can reduce downtime associated with feed failures and extend the lifespan of their contact tips and nozzles. The smooth surface design interacts gently with the wire, preserving its coating and shape as it enters the weld pool. Whether you are upgrading your current NA-5S configuration or replacing worn components, this drive roll delivers the performance and durability expected from industry-leading welding equipment.
