KP2116-2 - Lincoln Electric Incoming Guide Tube for NA-3S/NA-4/NA-5S Feeders

Precision Wire Alignment for Automatic Feeders

The Lincoln Electric KP2116-2 Incoming Guide Tube is a specialized component engineered to facilitate the smooth transfer of welding wire into the drive roll assembly of heavy-duty automatic feeders. Designed to accommodate a broad range of wire diameters from 3/32 inch to 7/32 inch (2.4 mm to 3.6 mm), this guide tube is an essential replacement part for Lincoln Electric's NA-series equipment, including the NA-3S, NA-4, and NA-5S models. Its robust construction is tailored to withstand the mechanical stresses associated with feeding large-diameter solid and cored wires used in industrial fabrication.

In automated welding processes such as submerged arc welding (SAW), the consistency of wire delivery is critical to weld quality. The KP2116-2 acts as the initial alignment point, ensuring that the wire enters the drive rolls at the correct angle. This prevents premature wear on the rolls and reduces the likelihood of wire shaving or jamming, which can cause costly downtime. By maintaining a centered wire path, this guide tube contributes to stable arc performance and uniform deposition rates.

As a genuine Lincoln Electric OEM part, the KP2116-2 guarantees perfect compatibility and ease of installation. It is manufactured to tight tolerances to ensure that even stiff or heavy wires feed consistently without binding. Regular inspection and replacement of the incoming guide tube are recommended practices for maintenance teams looking to maximize the lifespan of their wire feeding equipment and maintain high productivity levels in the shop.
