The Pinnacle Alumina 10N Ceramic Nozzles #4 are specialized components used in TIG (Tungsten Inert Gas) welding torches, compatible with both T17 and T26 torch models. These ceramic nozzles are designed to direct shielding gas around the tungsten electrode during welding, ensuring a clean and precise weld. The “#4” designation indicates the size of the nozzle, which is suitable for specific welding applications and torch configurations. Pinnacle Alumina Ceramic Nozzles are essential for maintaining optimal gas flow and shielding in TIG welding processes, particularly in metal fabrication, automotive, aerospace, and precision welding applications.
