OVERVIEW

Heavy-Duty Wire Feeding for Automation

The Lincoln Electric K347A Wire Drive is a specialized component engineered exclusively for the NA-5SF automatic wire feeder series. Designed to meet the rigorous demands of heavy industrial fabrication, this wire drive assembly ensures precise and reliable wire delivery for automated welding setups. It is particularly optimized for handling solid electrode wires, making it a staple in environments where consistency and high-deposition rates are critical.

High-Torque Performance

At the core of the K347A is its impressive 142:1 gear ratio. This high reduction ratio is specifically selected to generate the substantial torque required to push large diameter wires without slippage or hesitation. Capable of handling wire diameters ranging from 3/32 inch to 7/32 inch (2.4 mm to 5.6 mm), this drive unit is built to manage the mechanical resistance often encountered with thicker solid wires used in Submerged Arc or heavy MIG applications.

Speed and Precision

While torque is paramount for heavy wires, the K347A does not sacrifice control. It offers a maximum wire feed speed of 290 IPM (Inches Per Minute), providing a broad operating window for various welding procedures. Whether you are running a slow, high-deposition pass or a faster fill pass, this drive unit responds with the accuracy needed to maintain a stable arc and uniform bead profile. The inclusion of a wire straightener further enhances performance by ensuring the wire enters the contact tip smoothly, reducing wear and improving electrical contact.

Compatibility and Design

This model is the standard wire drive configuration for NA-5SF feeders and comes without high frequency insulation. It is a direct replacement or upgrade part that integrates seamlessly with existing Lincoln Electric automation systems. By maintaining the integrity of the wire feed path, the K347A minimizes downtime associated with feed failures, ensuring your automated lines remain productive and efficient.
