E2A5165 - 0.035 Cold Wire Feed Drive Roll Set

Precision Drive Roll Kit for Cold Wire Feed Systems

The E2A5165 Drive Roll Kit is a specialized component designed to facilitate the smooth and accurate feeding of .035-inch (0.9mm) welding wire in Cold Wire Feed (Cold WF) applications. In automated and semi-automated welding processes, particularly Gas Tungsten Arc Welding (GTAW/TIG) where cold wire feeders are utilized, the consistency of the wire delivery is paramount to achieving a defect-free weld bead. This kit is engineered to meet those rigorous standards, providing a reliable mechanical interface between the feeder motor and the consumable wire.

Manufactured from high-grade hardened steel, the drive rolls in this kit feature precision-machined grooves specifically sized for .035" wire. This exact sizing is critical; a groove that is too large will cause slippage and erratic feeding, while a groove that is too small can deform the wire, leading to liner clogging or poor arc characteristics. The geometry of the groove is optimized to grip the wire firmly without crushing it, preserving the wire's roundness and surface finish as it travels through the liner to the weld pool.

This kit is an essential maintenance item for keeping cold wire feed systems operational. Over time, drive rolls can wear down, losing their ability to grip the wire effectively. Replacing them with the E2A5165 kit restores the feeder's performance, ensuring that the wire speed remains constant and matches the programmed parameters. This consistency is vital for maintaining the correct fill rate and heat input in precision welding tasks. The kit typically includes the necessary rolls and associated hardware required for a standard changeover, making it a straightforward solution for equipment maintenance.

Whether used in an industrial manufacturing setting or a specialized fabrication shop, this drive roll kit supports the integrity of the welding process. By ensuring reliable wire feeding, it helps operators and automation systems produce high-quality welds with minimal downtime due to feeding issues. It is compatible with systems designated for Cold WF operations requiring .035" wire handling.
