171115-011 - Tweco .035/.045 V-Groove Drive Roll for Solid Wire

Precision Wire Feeding for Industrial Applications

The Tweco 171115-011 Drive Roll is an essential component for maintaining the efficiency and reliability of your MIG welding operations. Designed specifically for feeding solid wires, this drive roll features a precision-machined "V" groove geometry. The V-groove is the industry standard for hard wires, such as mild steel (ER70S-6) and stainless steel, as it provides the necessary grip to push the wire through the liner and contact tip without deforming the wire's cross-section. Deformation can lead to poor electrical contact and erratic arcs, making the quality of your drive roll a critical factor in overall weld quality.

This particular model is a dual-size, reversible unit, offering exceptional versatility for workshops that handle multiple fabrication tasks. One side of the roll is machined for .035-inch (0.9 mm) wire, while the flip side accommodates .045-inch (1.2 mm) wire. This dual-design reduces inventory requirements and allows operators to switch between wire diameters quickly during job changeovers. The roll is compatible with specific Tweco and Thermal Arc wire feeders, including the popular Fabricator series, ensuring a perfect fit and seamless integration into your existing equipment.

Manufactured from high-grade hardened steel, the Tweco 171115-011 is built to withstand the continuous friction and mechanical stress of industrial welding environments. Worn drive rolls are a common cause of wire slippage, bird-nesting, and inconsistent feed speeds. By replacing worn components with genuine Tweco parts, you ensure that your wire feeder operates at peak performance, delivering the consistent wire stick-out and deposition rates required for code-quality welds. Whether you are welding structural steel or precision stainless components, this drive roll provides the traction and stability needed for smooth, uninterrupted production.

Key Technical Benefits

Proper tensioning is vital when using V-groove rolls. These rolls are designed to work with the tensioner assembly to apply just enough pressure to move the wire without crushing it. The smooth surface of the groove minimizes the generation of metal shavings, which can otherwise clog liners and contact tips. This attention to detail in the manufacturing process translates to reduced downtime for maintenance and cleaning, keeping your arc on time higher and your production costs lower.
