171435-015 - Tweco 3/64" Double Drive Roll Kit (2-Roll Set)

Smooth Feeding for Better Welds: Tweco 3/64" Drive Roll Kit

Every welder knows that a stable arc starts with a steady wire feed. If your wire is slipping, stuttering, or birdnesting at the feeder, your weld quality suffers immediately. The Tweco 171435-015 Drive Roll Kit is the solution for welders running 3/64-inch (1.2mm) wire who need to restore reliable performance to their machine. This kit features a 2-roll double drive configuration, designed to grip the wire firmly and push it through the liner with consistency, ensuring that your voltage and amperage stay exactly where you set them.

Drive rolls are wear items, just like contact tips and nozzles. Over time, the grooves that grip the wire can become smooth or clogged with debris, leading to slippage. When the rolls slip, the wire slows down, causing the arc length to increase and potentially burn back into the tip. By installing a fresh set of Tweco 171435-015 rolls, you eliminate these variables. These rolls are built from hardened steel to withstand the rigors of daily shop use, making them a durable investment for any fabrication environment.

This kit is specifically designed for 3/64" wire, a versatile size often used for structural work and heavy repairs. The "Double Drive" design ensures that the wire is fed evenly, reducing the chance of deformation. Flattened or deformed wire can cause drag inside the gun liner and premature wear on the contact tip. With these precision-engineered rolls, the wire retains its shape, feeding smoothly all the way to the puddle.

Installation is straightforward and takes only minutes. Simply remove the old rolls, clean the drive shafts, and slide the new 171435-015 rolls into place. Make sure to adjust your tensioner correctly—tight enough to feed, but loose enough that the rolls will slip if the wire hits a hard obstruction (saving your birdnest). Whether you are welding mild steel, stainless, or flux-cored wire, having the right drive rolls is the first step to a frustration-free day under the hood. Keep your arc smooth and your beads consistent with genuine Tweco replacement parts.
