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

Optimize Your MIG Welder for Dual Shield Wire

Upgrade your welding setup with the Tweco 171435-007 Drive Roll Kit, engineered specifically for the demands of Flux-Cored (FCAW) and Dual Shield welding. When welding with 1/16-inch tubular wires, standard smooth drive rolls often fail to provide adequate traction, leading to wire slippage, irregular arc length, and frustrating burn-back issues. This genuine Tweco kit solves those problems by providing a robust, knurled feed path tailored for soft, cored wires.

The kit is designed for 2-roll drive systems and features a textured (knurled) groove. This texture acts like a gear, gripping the wire securely. This is critical for flux-cored welding because it allows the operator to set the drive roll tension lower than would be required with smooth rolls. Lower tension preserves the round shape of the tubular wire, preventing it from becoming oval or flattened. Flattened wire causes excessive friction inside the MIG gun liner and premature wear on contact tips, resulting in downtime and increased consumable costs.

Installation is straightforward, allowing you to switch between wire types and sizes quickly to keep production moving. The 171435-007 kit is manufactured to precise tolerances, ensuring that the wire remains centered and aligned with the inlet and outlet guides of your feeder. This alignment is crucial for preventing "birdnesting"—the tangling of wire at the drive rolls—which is a common headache when pushing soft wires through long cable assemblies.

Invest in the correct drive rolls to maximize the efficiency of your welding operations. With the Tweco 171435-007, you get the reliability of an OEM part designed to deliver smooth, uninterrupted wire feeding for your heavy-duty welding projects.
