Heavy-Duty Submerged Arc Solutions

Maximize the efficiency of your automated welding operations with the Lincoln Electric K231-1 Submerged Arc Contact Nozzle Assembly. Designed for the serious industrial welder, this genuine Lincoln Electric part is the standard nozzle assembly for the K231 Single Wire Submerged Arc Torch. Whether you are welding heavy structural steel, pressure vessels, or pipe, this assembly delivers the reliability and performance professionals expect from the Lincoln brand.

Versatile and Efficient Design
One of the biggest challenges in submerged arc welding is managing consumables and flux. The K231-1 addresses this with a smart design that includes a specialized outer flux cone. This cone directs the granular flux exactly where it is needed—around the arc—ensuring complete coverage without unnecessary waste. This not only improves weld quality by preventing porosity but also saves money on flux costs over time. The assembly comes ready to weld with standard wire sizes including 3/32 inch, 1/8 inch, and 5/32 inch, covering the most common industrial applications right out of the box.

Adaptable for Any Job
Flexibility is key in a job shop environment. While the K231-1 comes set up for mid-range wire sizes, it is fully adaptable for lighter or heavier gauge wires. By simply adding the appropriate KP1962 tips (sold separately), you can convert this nozzle to run wires as small as 5/64 inch or as large as 7/32 inch. This modularity means you can keep one nozzle assembly on your machine and simply swap tips as your project requirements change, reducing downtime and inventory costs.

Built for the Long Haul
Rated for up to 600 amps, this contact nozzle assembly is built to handle high-deposition welding day in and day out. When you choose genuine Lincoln Electric parts from Welders Supply, you are investing in equipment that ensures consistent electrical contact and smooth wire feeding, resulting in superior bead appearance and structural integrity.
