375980-051 - Tweco 3/64" V-Groove Drive Roll Kit for 4-Roll Feeders

Precision Wire Feeding for Industrial Applications

The Tweco 375980-051 Drive Roll Kit is a specialized component engineered for heavy-duty industrial wire feeding systems. Designed specifically for 3/64-inch (1.2mm) wire diameters, this kit utilizes a V-Groove profile, which is the industry standard for feeding solid hard wires such as mild steel and stainless steel. The V-shape provides two points of contact on the wire, ensuring sufficient traction to push the wire through the liner and gun cable without deforming the wire's cross-section or creating metal shavings that can clog liners.

This kit is designated for 4-Roll wire feeder systems, commonly found in high-amperage industrial MIG welders (such as Thermal Arc or Tweco UltraFeed units). 4-roll systems offer superior feeding force compared to 2-roll systems by distributing the pressure over a larger surface area, minimizing wire slippage. The rolls in this kit are manufactured from hardened steel to resist wear from continuous friction, ensuring a long service life and maintaining consistent wire feed speeds, which is critical for automated or high-precision manual welding parameters.

Proper drive roll selection is essential for maintaining the integrity of the welding arc. Using the correct size and groove type prevents feed issues like birdnesting or erratic arc starts. This genuine Tweco/Thermal Arc replacement part ensures perfect fitment and alignment within the wire drive assembly.
