375980-065 - Tweco 3/32" Cogged Drive Roll Kit (4-Roll System)

Precision Drive Rolls for 3/32" Welding Wire

Optimize your wire feeder's performance with the Tweco 375980-065 Drive Roll Kit, a specialized accessory for professional welders handling large-diameter consumables. This kit is configured for 4-roll wire drive systems and is machined to accommodate 3/32-inch (2.4mm) wire. When working with wires of this caliber—typically in Flux-Cored Arc Welding (FCAW) or heavy-deposition MIG applications—standard smooth rolls often fail to provide adequate grip. The Tweco 375980-065 solves this with a robust cogged design that bites into the wire just enough to ensure non-slip feeding.

The "D COG" specification indicates a drive configuration meant for positive engagement. In a 4-roll system, having all rolls working in unison provides superior feeding force compared to 2-roll setups. This is crucial when the wire must be pushed through long distances or when the torch cable is bent during operation. The serrated teeth on these rolls prevent the wire from slipping, which is a common cause of arc stuttering and spatter. By ensuring a constant wire speed, these drive rolls contribute directly to the stability of the welding arc and the overall quality of the finished weld.

Installation is straightforward for maintenance personnel familiar with Tweco and Thermal Arc feeders. Using genuine OEM parts like the 375980-065 guarantees that the gear mesh and alignment are correct, preventing premature wear on the feeder motor and gearbox. This kit is built from hardened steel to withstand the abrasive nature of welding wire and the rigors of daily industrial use. Keep your equipment running at peak efficiency and reduce maintenance intervals by installing high-quality drive rolls designed specifically for your wire size and application.
