K347B-1 - NA-5SF Automatic Wire Feeder Head 95:1

Reliable Feeding for Heavy-Duty Automation

When your automated welding line is running thick wire, you need a feeder that won't quit. The Lincoln Electric K347B-1 NA-5SF Wire Drive Head is the muscle behind the arc, designed specifically to push 1/16" to 3/32" wire through the system without skipping a beat. If you are running an NA-5 automatic system, this is the drive head that gives you the torque you need. With a 95:1 gear ratio, this unit trades extreme speed for unstoppable pushing power, ensuring that even stiff, heavy-gauge wires feed smoothly through the conduit and contact tip. This consistency is exactly what you need to keep your weld beads uniform and your defect rates low.

We know that in a shop environment, equipment takes a beating. The NA-5SF is built Lincoln-tough to handle the heat, dust, and long duty cycles of structural steel fabrication, shipbuilding, and tank manufacturing. It’s not just a replacement part; it’s an upgrade in reliability. The drive mechanism is engineered to prevent wire slippage, which is a common headache in automated setups that leads to uneven welds and downtime. By maintaining a constant feed rate, this head helps you achieve deep penetration and solid fusion, shift after shift.

Installation is standard for the NA-5 platform, meaning you can swap this unit in and get back to running production quickly. Whether you are setting up a new sub-arc station or refurbishing an old beam welder, the K347B-1 delivers the performance you expect from Lincoln Electric. It handles the heavy lifting so your operators can focus on monitoring the process and maintaining quality. Don't let a weak feeder be the bottleneck in your production line—equip your machine with the high-torque NA-5SF and keep the wire moving.
