OVERVIEW

Precision Wire Feeding for Heavy Industrial Applications

The Tweco 375980-066 Drive Roll Kit is a specialized component designed to optimize the performance of 4-roll wire feeder systems. Engineered specifically for handling large diameter 7/64-inch (approx. 2.8mm) welding wires, this kit is an essential upgrade or replacement for industrial welding setups. The kit features a "D Cog" (Cogged) profile, which is critical when feeding tubular wires such as flux-cored or metal-cored varieties.

In heavy fabrication environments, wire feeding issues can lead to costly downtime and weld defects. Standard V-groove rolls often require high tension to grip the wire, which can deform hollow cored wires. The cogged design of these Tweco rolls solves this problem by using teeth to engage the wire surface gently but firmly. This allows for positive feeding traction with significantly less crushing force, preserving the structural integrity of the wire and ensuring a consistent electrical contact at the tip.

This kit is compatible with select Tweco and Thermal Arc 4-roll wire feeders, providing a direct fit and reliable operation. Whether you are welding structural steel, heavy equipment, or shipbuilding components, ensuring your feed system is equipped with the correct drive rolls is paramount for arc stability and weld quality.

FAQ

This kit is specifically designed for 7/64-inch (approximately 2.8mm) welding wire.

The cogged (D Cog) profile provides teeth that grip the wire, offering positive traction without the need for excessive pressure. This is ideal for cored wires that can be easily crushed.

While physically possible, cogged rolls are typically reserved for cored wires. Using them on solid wire may cause indentations on the wire surface which could accelerate liner wear.

This kit is designated '4RL', indicating it is designed for use with 4-roll wire feeder systems.

Yes, the kit typically includes the drive rolls required to configure the feeder for the specified wire size.

These are generally compatible with Tweco and Thermal Arc wire feeders that utilize the specific 4-roll drive system.

7/64" is a large diameter wire used for high-deposition welding in heavy industrial applications, often requiring the extra grip provided by these rolls.

If the teeth on the cogs appear worn down, or if you experience wire slippage despite correct tension settings, it is time to replace the rolls.
