KP1973-1 - Lincoln Electric KP1973-1 Subarc Nozzle Tip

Precision Performance for Subarc Applications

The Lincoln Electric KP1973-1 Nozzle Tip is a critical component for welders and operators utilizing Lincoln's submerged arc welding (SAW) systems. In the SAW process, where high deposition rates and deep penetration are the goals, the stability of the arc and the precision of the wire delivery are paramount. This nozzle tip is crafted to handle the intense heat and high current densities typical of subarc welding, providing a stable electrical connection to the welding wire as it passes through the gun assembly.

Designed for use with Lincoln Electric mechanized SAW guns, such as the K114 series, the KP1973-1 ensures that the wire is guided accurately into the weld joint. Wear and tear on nozzle tips can lead to keyholing or poor contact, which in turn causes micro-arcing inside the tip, wire burn-back, or wandering arcs. Replacing your worn tips with a fresh KP1973-1 restores the electrical efficiency of the gun, resulting in cleaner starts and more consistent bead profiles. The copper alloy construction is optimized for thermal conductivity, helping to dissipate heat effectively and prolong the life of the consumable.

For maintenance personnel and welding engineers, using the correct nozzle tip is essential for maintaining procedure specifications. The KP1973-1 is built to tight tolerances, ensuring it threads or seats correctly within the nozzle assembly without gas leakage (where applicable) or mechanical play. Whether you are welding thick-wall pressure vessels or long structural beams, this tip provides the reliability needed for long, continuous welds. Keep your subarc setup running at peak performance by inspecting your contact tips regularly and replacing them with the KP1973-1 when signs of wear appear.

Technical Advantages:

• High Conductivity: Superior copper formulation ensures efficient current transfer to the wire.
• Heat Resistance: Withstands the radiant heat of the submerged arc process.
• Precision Fit: Engineered for Lincoln subarc guns to prevent wire misalignment.
