375980-045 - Tweco 1/16" Flux-Cored Drive Roll Kit for 4-Roll Feeders

Precision Feeding for Heavy Fabrication

The Tweco 375980-045 Drive Roll Kit is an essential component for industrial wire feeding systems, specifically engineered for 4-roll wire feeders. This kit is calibrated for 1/16-inch (1.6 mm) wire diameters, a standard size for structural and heavy fabrication applications. The rolls feature a specialized knurled groove design, denoted as FL/DS (Flux/Dual Shield), which provides the necessary mechanical grip to feed tubular wires effectively without crushing the thin metal sheath.

In a 4-roll system, the feeding force is distributed across two pairs of rolls, allowing for lower individual pressure settings while maintaining positive traction. This reduces the deformation of flux-cored wires, ensuring that the flux density remains consistent throughout the weld. The 375980-045 kit is manufactured to tight tolerances to ensure concentricity and balance, minimizing vibration and motor load during operation. It is compatible with select Tweco and Thermal Arc wire feeders designed for heavy-duty cycles.

Proper drive roll selection is critical for maintaining arc stability. Using smooth V-groove rolls on flux-cored wire can lead to slippage, while U-groove rolls are typically reserved for aluminum. This knurled kit bridges the gap, offering aggressive traction for cored wires. Maintenance professionals should verify the feeder model compatibility and ensure that all four rolls are replaced simultaneously to prevent uneven wear and feeding issues.
