KP1990-1 - Lincoln Electric 3/32" Guide Tube Extension with 2-1/4" ESO

Lincoln Electric KP1990-1 Guide Tube Extension Overview

The Lincoln Electric KP1990-1 Guide Tube Extension is a critical component designed to enhance the precision and reliability of your welding operations. Engineered specifically for use with 3/32-inch diameter welding wire, this extension plays a vital role in guiding the wire accurately from the feeder to the workpiece. In industrial welding environments, particularly those involving automated or semi-automated processes, maintaining consistent wire alignment is essential for achieving high-quality welds. This genuine Lincoln Electric part ensures that your equipment operates at peak performance, minimizing the risk of feed issues that can lead to costly downtime.

One of the defining features of the KP1990-1 is its design to provide a 2-1/4 inch Electrical Stick Out (ESO). Electrical Stick Out refers to the distance from the contact tip to the workpiece, a parameter that significantly influences the welding current and the amount of resistive heating the wire experiences before entering the arc. By utilizing a guide tube extension with a fixed, precise length, operators can maintain a consistent ESO, resulting in more stable arc characteristics and uniform bead profiles. This is particularly advantageous in submerged arc welding (SAW) and heavy-duty MIG applications where deposition rates and penetration depth must be strictly controlled.

Durability is a hallmark of Lincoln Electric components, and the KP1990-1 is no exception. Constructed from robust materials capable of withstanding the friction and heat generated during continuous welding, this guide tube extension resists wear and deformation. Using genuine OEM parts like the KP1990-1 not only guarantees a perfect fit with your existing Lincoln Electric wire feeders and guns but also prolongs the lifespan of your consumable assembly. Whether you are fabricating structural steel or performing heavy equipment repair, this guide tube extension is an indispensable tool for maintaining the integrity and efficiency of your welding process.

At Josef Gas, we understand the importance of reliable equipment in your production line. The KP1990-1 is supplied as a single unit, ready for immediate installation. By ensuring your wire feeding system is equipped with the correct guide tubes and extensions, you can achieve smoother wire delivery, reduced spatter, and overall superior weld quality.
