The Tweco 171435-004 is a specialized drive roll kit engineered for the precise feeding of .045-inch (1.2mm) tubular welding wires. In industrial MRO and fabrication settings, the integrity of the wire feed system is critical to maintaining arc stability and weld quality. This kit is specifically designed for Flux Cored (FCAW) and Dual Shield applications where standard V-groove rollers often fail to provide adequate traction or inadvertently deform the wire.
This OEM kit features a knurled (serrated) groove profile. Unlike smooth V-grooves used for solid wires, the knurled teeth bite gently into the softer shell of flux-cored wires, providing positive drive force without requiring excessive tension that could crush the wire. Crushed flux-cored wire can lead to poor electrical contact in the contact tip and erratic arc characteristics. By using the correct 171435-004 kit, operators ensure the wire retains its round shape and flux density throughout the feeding process.
Designed as a 2-roll system, this kit is compatible with specific Tweco and Thermal Arc wire feeders (verify model compatibility via service manual). The components are manufactured from hardened steel to resist wear from the abrasive nature of flux-cored wires, ensuring a long service life and reduced maintenance intervals. Proper installation of these rolls is essential for preventing "bird-nesting" and ensuring consistent wire speed, which is directly correlated to amperage and penetration in CV welding processes.
