375980-011 - Tweco 3/64" V-Groove Drive Roll Kit - Double Sided

Precision Wire Feeding for Industrial Applications

The Tweco 375980-011 Drive Roll Kit is an essential component for maintaining the efficiency and reliability of your MIG welding operations. Designed specifically for feeding 3/64-inch (1.2mm) solid welding wires, this kit features a precision-machined V-Groove profile. In the physics of wire feeding, the interface between the drive roll and the welding wire is critical; the V-groove geometry provides the necessary friction to push hard wires—such as mild steel and stainless steel—through the liner and gun cable without crushing or deforming the wire cross-section. This ensures that the electrical contact at the tip remains consistent, promoting a stable arc.

One of the standout technical features of this component is its Double-Sided (DS) configuration. Industrial environments demand longevity from consumables to minimize downtime. By machining the groove into both sides of the roll, Tweco allows operators to simply flip the roll when one side shows signs of wear, effectively doubling the service life of the part. This design consideration reflects a focus on operational cost-efficiency and maintenance reduction.

Proper drive roll selection is paramount to preventing common feeding issues such as "bird-nesting" or erratic wire speeds. Using a V-groove roll for solid wire is the industry standard, as opposed to knurled rolls (for flux-cored) or U-groove rolls (for aluminum). The 375980-011 is manufactured from hardened steel to withstand the mechanical stress of continuous feeding cycles. It is engineered to fit specific Tweco and Thermal Arc wire feeding systems, ensuring a perfect fit with the drive motor shaft and pressure arm assembly. Integrating this OEM-quality replacement part restores your machine's feeding performance to factory specifications.

Whether you are operating a manual MIG setup or a more automated system, the consistency of your wire feed speed is directly correlated to weld quality. Slippage at the drive rolls leads to burn-back and arc instability. By installing the correct 3/64" V-Groove kit, you ensure positive traction and smooth delivery of filler metal to the weld pool.
