KP1890-1 - Lincoln Electric KP1890-1 Tiny Twin Center Drive Roll 5/64-3/32 in

Maximize Deposition with Genuine Lincoln Parts

Elevate the performance of your submerged arc or heavy-duty MIG operations with the Lincoln Electric KP1890-1 Drive Roll Center. Specifically engineered for the Tiny Twin wire feeder series, this replacement roll is essential for welders utilizing twin-wire process technologies. Capable of accommodating wire sizes of 5/64 inch and 3/32 inch (2.0 mm - 2.4 mm), it is the standard for heavy fabrication tasks requiring high deposition rates and deep penetration.

The "Tiny Twin" process is a game-changer for productivity, effectively doubling the amount of filler metal delivered to the joint compared to single-wire setups. However, this performance relies heavily on the consistency of the wire feed. The KP1890-1 acts as the central hub of traction in the drive assembly, ensuring that both wires are fed at a uniform speed. Any fluctuation in wire speed can lead to arc blow, uneven bead profiles, or burn-backs. Lincoln Electric has designed this drive roll with a specific surface texture and hardness to grip the wire firmly without shaving or crushing it, ensuring a smooth path through the liner and contact tip.

Welders Supply is your trusted source for hard-to-find and specialized welding components. We know that for heavy manufacturing sectors—such as shipbuilding, pressure vessel construction, and bridge building—equipment reliability is non-negotiable. The KP1890-1 is built to resist wear, even when feeding flux-cored or solid wires continuously. Its robust construction reduces the frequency of replacement, lowering your overall cost of ownership and maintenance burden.

Installation is straightforward, allowing maintenance teams to swap out worn rolls quickly and return the machine to service. When you choose the KP1890-1, you are choosing a part that meets Lincoln Electric's rigorous quality standards. Don't compromise your high-efficiency twin-wire welding process with inferior aftermarket substitutes. Ensure precise alignment and reliable feeding with this genuine center drive roll, designed to keep your arcs lit and your production line moving.
