K346B - Lincoln Electric NA-5S Wire Drive Assembly 95:1 Gear Ratio

Heavy-Duty Automation for Submerged Arc Welding

Maximize the efficiency of your automatic welding operations with the Lincoln Electric K346B Wire Drive, specifically tailored for the NA-5S controller series. This assembly is built to handle the rigors of heavy fabrication, offering a dependable solution for feeding solid wires in the 1/16" to 3/32" diameter range. At the heart of the unit is a heavy-duty gearbox with a 95:1 ratio. This gearing is engineered to deliver smooth, non-slip wire delivery at speeds up to 456 IPM, ensuring that your deposition rates remain constant even during long weld cycles.

The K346B is more than just a motor; it is a comprehensive feeding solution. It arrives complete with a wire straightener to correct cast and helix issues before the wire reaches the contact tip, promoting better arc stability and bead placement. Additionally, the integrated flux hopper makes this unit ready for Submerged Arc Welding (SAW) immediately. The hopper system is designed to dispense flux consistently over the arc, protecting the weld pool and ensuring high-quality metallurgical results. The package also includes the necessary cabling—a 4ft motor cord and a 4ft flux hopper cord—to interface seamlessly with your existing NA-5S infrastructure.

Operators and maintenance teams will appreciate the rugged design and ease of integration. The lack of high-frequency insulation indicates this unit is optimized for standard industrial automation setups where HF starting is not required. From shipbuilding to structural steel, the K346B provides the mechanical reliability needed to keep automated lines running with minimal downtime. Trust in Lincoln Electric's engineering to provide a wire drive that matches the high standards of your production goals.
