171435-007 - Tweco 1/16" Flux-Cored / Dual Shield Drive Roll Kit (2-Roll System)

Reliable Wire Feeding for Flux-Cored Applications

The Tweco 171435-007 Drive Roll Kit is a specialized accessory designed to enhance the performance of your wire feeding system when working with 1/16-inch (1.6 mm) flux-cored or dual-shield welding wires. In industrial welding environments, the consistency of wire delivery is paramount to achieving sound welds, particularly when using tubular wires that are softer and more prone to deformation than solid wires.

This kit features a knurled groove design. Unlike smooth V-groove rolls used for solid steel wire, knurled rolls possess small teeth that bite gently into the surface of the flux-cored wire. This mechanical grip allows the feeder to push the wire through the liner and gun cable with positive traction, without requiring excessive tension on the pressure arm. High tension on tubular wires can crush the wire, leading to feeding issues, liner clogging, and poor electrical contact at the contact tip. By using the correct Tweco knurled rolls, you ensure the structural integrity of the wire is maintained from the spool to the arc.

Designed for 2-roll wire feed systems commonly found in Tweco and Thermal Arc equipment, this kit includes the necessary components to swap out your existing rolls. Whether you are fabricating structural steel, heavy equipment, or performing maintenance repairs, ensuring your feeder is equipped with the correct drive rolls for the wire type and diameter is the first step in quality control. The 171435-007 kit is built from hardened steel to resist wear, providing long-lasting performance even in high-duty cycle applications.

Key Benefits:

• Precision Fit: Engineered specifically for 1/16" diameter wires.
• Enhanced Traction: Knurled surface prevents slippage without crushing the wire.
• System Compatibility: Fits select Tweco/Thermal Arc 2-roll feeders.
