KP1901-1 - Lincoln Electric Tiny Twinarc .045-3/32 Wire Drive Roll & Guide Kit

Technical Overview: Lincoln Electric KP1901-1 Tiny Twinarc Drive Roll Kit

The Lincoln Electric KP1901-1 is a specialized consumable and hardware kit designed for wire feeders utilizing the Tiny Twinarc process. This kit is engineered to facilitate the feeding of two wires simultaneously, a configuration often used in submerged arc and high-deposition MIG applications to increase productivity. The kit is comprehensive, addressing the drive roll, guiding, and electrical contact requirements for a wide range of wire diameters, specifically 0.045", 0.052", 1/16", 5/64", and 3/32".

Proper wire feeding geometry is critical in twin wire applications to prevent tangling and ensure consistent arc characteristics. The KP1901-1 kit includes a set of drive rolls tailored for wires ranging from 0.045" to 5/64". For the larger 3/32" wire, the kit provides a complete drive roll assembly. This assembly is composed of outer drive rolls, center drive rolls, a drive roll spacer, and a drive roll key, ensuring that the heavier wire is fed with the necessary torque and precision without deformation. The inclusion of these specific assembly parts allows for a seamless transition between wire sizes without the need for additional hardware procurement.

Beyond the drive mechanism, the kit supplies the necessary downstream consumables. It includes guide tubes and wire guides that are machined to tight tolerances to maintain the parallel alignment of the two wires as they enter the gun or torch. Corresponding contact tips are also provided, ensuring optimal electrical conductivity and arc stability. The components are manufactured from durable materials designed to resist wear from the constant friction of moving wire, thereby extending the service life of the feeder setup.

This kit is an essential maintenance item for facilities running Lincoln Electric NA-series heads or other compatible Tiny Twinarc equipment. By bundling these critical components, Lincoln Electric ensures that operators have the correct mating parts for the specific wire diameters being used, mitigating feeding issues commonly associated with mismatched drive rolls or worn guides. The KP1901-1 represents a complete solution for maintaining the mechanical integrity of your twin wire feeding system.
