The Tweco 171435-003 Drive Roll Kit is a specialized component designed to optimize the performance of Thermal Arc and Tweco wire feeding systems when using flux-cored or dual-shield welding wires. This kit features a 2-roll system configuration specifically engineered for .035 inch (0.9 mm) diameter wires. Unlike standard V-groove rollers used for solid wires, this drive roll utilizes a knurled groove design. This textured surface provides the necessary mechanical grip to feed soft, tubular wires effectively without requiring excessive tension arm pressure, which can crush the wire and lead to feeding issues.
This drive roll kit is the OEM replacement part for the popular Thermal Arc Fabricator series, including the Fabricator 181i, 211i, and 252i multi-process welders. The internal geometry is machined to strict tolerances to ensure concentricity and balance, reducing vibration in the feed mechanism. The knurling pattern is calculated to maximize traction while minimizing the generation of metal shavings or wire deformation. Proper selection of drive rolls is critical for maintaining arc stability in Flux-Cored Arc Welding (FCAW), as inconsistent wire speeds directly affect voltage and amperage output.
Installing the 171435-003 is straightforward, fitting directly onto the keyed shaft of the wire feed motor. It is essential to match the drive roll size to the wire diameter exactly; using this .035" roller with larger or smaller wires will result in poor performance. For industrial MRO procurement, this SKU represents a vital consumable for maintaining the operational readiness of fabrication equipment. Regular inspection of drive rolls for wear—specifically the dulling of the knurled teeth—is recommended to prevent unplanned downtime.
