KP2721-1 - Lincoln Electric 5-Inch Nozzle Extension for K231 Subarc Torches

Lincoln Electric KP2721-1 Nozzle Extension for Submerged Arc Welding

The Lincoln Electric KP2721-1 is a specialized nozzle extension designed to enhance the versatility of K231 series submerged arc torches. Engineered for heavy industrial fabrication, this component extends the reach of the welding nozzle by 5 inches, allowing operators to effectively weld deep grooves, corners, and other hard-to-access joints that standard configurations cannot reach. It is a critical accessory for structural steel, pipe fabrication, and heavy equipment manufacturing where submerged arc welding (SAW) is the process of choice.

Built to withstand the intense demands of high-deposition welding, the KP2721-1 is rated for 600 Amps, ensuring it maintains electrical integrity and structural stability even during prolonged welding cycles. It is specifically designed to accommodate large diameter wires, supporting sizes up to 1/4 inch (6.4 mm). This capability makes it suitable for high-current applications requiring significant metal deposition rates. The extension integrates seamlessly with Lincoln Electric K231-1 and K231-2 submerged arc torches, ensuring a secure fit and optimal electrical conductivity.

Reliability is paramount in automated and semi-automated welding environments. This nozzle extension is manufactured to Lincoln Electric's rigorous standards, providing consistent performance and long service life. By enabling access to restricted areas, it reduces the need for complex torch repositioning or alternative, less efficient welding methods. Whether you are welding thick-walled pressure vessels or massive structural beams, the KP2721-1 ensures your subarc torch delivers the wire exactly where it is needed.
