54N14SC - CK 54N14SC #8 Silicon Nitride Super Cup for Large Diameter Gas Lens

High-Performance Silicon Nitride TIG Nozzle

The CK Worldwide 54N14SC is a specialized #8 TIG welding cup belonging to the "Super Cup" line, engineered from advanced Silicon Nitride material. Unlike standard alumina oxide nozzles, this industrial-grade ceramic offers exceptional resistance to thermal shock and high-reflective heat, making it the ideal choice for high-amperage welding applications where standard cups frequently fail or crack.

Technical analysis of the 54N14SC reveals a significant reduction in thermal conductivity—approximately 40% lower than traditional alumina cups. This material property ensures the nozzle remains structurally integral even under extreme duty cycles and rapid temperature fluctuations. The cup features a 1/2-inch (12.7mm) bore diameter and is designed to interface with Large Diameter Gas Lens collet bodies commonly found on 3-Series (17, 18, 26) TIG torches. By mitigating the risk of thermal cracking, this component ensures consistent gas coverage and reduces the frequency of consumable replacement in automated or heavy-manual welding environments.

This nozzle is particularly effective in confined spaces where reflected heat is intense, or during AC welding of aluminum where high energy is dispersed at the arc. The 54N14SC provides a robust solution for MRO operations seeking to optimize consumable inventory and minimize downtime associated with nozzle failure.
