K347B - Lincoln K347B Wire Drive Assembly for NA-5SF Feeder

Reliable Performance for Heavy Fabrication

Keep your automatic welding operations running at peak efficiency with the Lincoln Electric K347B Wire Drive. Designed as a direct replacement and upgrade for NA-5SF automatic wire feeders, this drive assembly is the heartbeat of your wire delivery system. When you are welding thick materials in a heavy fabrication setting, a stalled wire or inconsistent feed speed can ruin a weld and halt production. The K347B is built to prevent exactly that, offering the rugged durability Lincoln Electric is known for.

This unit features a powerful 95:1 gear ratio, which provides the torque needed to smoothly feed larger solid wires. It is rated for wire diameters from 1/16 inch up to 3/32 inch, covering the most common sizes used in heavy industrial welding. Despite its high-torque capabilities, it doesn't sacrifice speed, capable of delivering wire at up to 455 IPM. This versatility allows you to fine-tune your welding parameters for optimal penetration and deposition rates without worrying about the feeder keeping up.

The K347B is designed for straightforward integration into your existing equipment. It comes without high-frequency insulation, making it the standard choice for conventional MIG and flux-cored applications where HF start is not utilized. The robust construction ensures it stands up to the dust, heat, and vibration of a busy shop floor. Using genuine Lincoln Electric parts like the K347B not only extends the life of your NA-5SF feeder but also ensures that your warranty and performance standards remain intact.

Don't let worn-out drive components compromise your weld quality. The K347B Wire Drive ensures that every inch of wire is delivered with precision, giving your operators confidence in the equipment and your customers confidence in the final product. It is an essential component for any shop utilizing NA-5SF feeders for continuous, high-duty-cycle welding tasks.
