376246-010 - Tweco .035 Drive Roll Kit for Solid and Flux-Cored Wire

Precision Drive Rolls for .035" Wire Applications

The Tweco 376246-010 Drive Roll Kit is a critical replacement assembly for welders utilizing Tweco-compatible 2-roll wire feed systems. This kit is specifically calibrated for 0.035" (0.9mm) diameter wire, one of the most versatile and widely used gauges in the industry. The kit is identified as "FL/S," signifying its engineered compatibility with both Flux-Cored and Solid welding wires. This is achieved through specialized groove geometries that provide the necessary grip for soft flux-cored wires without crushing them, while offering the smooth traction required for solid steel wires.

Wire feeding issues are often misdiagnosed as contact tip or liner problems, when in reality, the root cause lies at the feeder. Worn drive rolls fail to push the wire with constant force, causing the wire speed to fluctuate. This fluctuation disrupts the voltage/amperage balance at the arc, leading to spatter and irregular bead profiles. The Tweco 376246-010 kit eliminates these variables. Manufactured to tight tolerances, these rolls ensure concentric rotation and uniform pressure application, which is vital for maintaining a steady arc length during complex welds.

For operators utilizing 2-roll systems, the importance of drive roll quality cannot be overstated. Unlike 4-roll systems which have more surface area to grip the wire, 2-roll systems rely heavily on the precise friction coefficient of a single pair of rolls. Tweco's design maximizes this efficiency. The kit includes the necessary components to refresh the drive mechanism, ensuring that the wire is guided accurately into the liner. This reduces friction throughout the gun cable and minimizes the risk of birdnesting at the feeder inlet.

Technical specifications include hardened steel construction for extended service life and resistance to grooving. The kit is designed for quick changeovers, minimizing downtime during maintenance intervals. When setting up for .035" wire, using the correct drive roll is mandatory for code-quality work. Do not compromise with generic fits; the Tweco 376246-010 provides the OEM assurance of performance, fitting seamlessly into your maintenance schedule and ensuring your equipment operates at peak efficiency.
