KP2114-2 - Lincoln Electric Middle Guide Tube for .045-.052 Wire (4-Roll)

Lincoln Electric KP2114-2 Guide Tube Overview

The Lincoln Electric KP2114-2 Guide Tube is a critical component designed for industrial wire feeding systems. Specifically engineered for use with wire diameters ranging from .045 to .052 inches (1.2-1.3 mm), this guide tube serves as the middle conduit in 4-roll wire drive assemblies. Maintaining the integrity of your wire feeding path is essential for consistent arc performance, and using genuine Lincoln Electric parts ensures that your equipment operates at manufacturer specifications.

In a 4-roll drive system, the wire must pass through multiple stages of drive rolls. The middle guide tube bridges the gap between these rolls, supporting the wire and preventing it from buckling or wandering off the drive path. This is particularly important when pushing softer wires or when feeding over longer distances. The KP2114-2 is manufactured to precise tolerances, ensuring that the internal diameter perfectly matches the specified wire range, thereby minimizing friction while providing adequate support.

Replacing worn guide tubes is a standard maintenance procedure that can prevent costly downtime. Over time, the abrasive nature of welding wire can groove or widen the guide tube, leading to erratic feeding. By installing a fresh KP2114-2, operators can restore the smooth, reliable feeding required for high-quality MIG and Flux-Cored welding applications. This part is compatible with various Lincoln Electric wire feeders utilizing the 4-roll drive configuration.
