K210-2 - NA-3S Automatic Wire Feeder Controller for SAW

Reliable Automation for the Professional Fabricator

Take command of your automated welding projects with the Lincoln Electric NA-3S Automatic Controller, a legendary piece of equipment known for its reliability and performance in the field. If you are setting up a Submerged Arc Welding (SAW) station or retrofitting a beam line, the NA-3S (K210-2) gives you the control you need to lay down perfect beads pass after pass. This unit is built for the serious fabricator who demands consistency, allowing you to focus on the weld parameters rather than fighting with the equipment.

The NA-3S is designed to make your life easier by offering incredible versatility in wire feeding. Whether you are running small diameter solid wire for precision work or feeding massive 7/32-inch wire for heavy fill passes, this controller handles it all with a feed speed range of 25 to 650 IPM. The interface is straightforward, giving you direct access to essential adjustments so you can dial in your procedure quickly. It is specifically tuned for use with Constant Current (CC) and Constant Voltage (CV) modes depending on your power source setup, making it a flexible tool for various submerged arc applications.

One of the standout features for operators is the unit's reliability. We know that in a heavy shop environment, equipment takes a beating. The NA-3S features a rugged housing and heavy-duty internal components that stand up to the heat and grime of continuous welding. It integrates flawlessly with industry-standard power sources like the Idealarc DC-600 and DC-1000, creating a setup that you can trust to perform shift after shift. The compact size also means it doesn't take up unnecessary space on your boom or carriage, leaving you more room to work and monitor the arc.

Ultimately, the NA-3S helps you weld faster and cleaner. By automating the wire delivery with such precision, you eliminate the inconsistencies of hand welding, resulting in smoother finishes and fewer defects. It includes the necessary control cable to get you hooked up and running. Whether you are welding bridge girders, large pipe, or heavy machinery components, the Lincoln NA-3S Automatic Controller is the partner you need to maximize your deposition rates and keep your production line moving efficiently.
