The right nozzle for the toughest TIG welding applications. Super Cups withstand high-amperage and high-reflective heat applications while minimizing cracking problems related to thermal shock. Benefits: Reduce problems of thermal stresses making Alumina Nozzles obsolete for high-heat applications. Reduce downtime. Reduce replacement part costs. Reduce effects of nozzle erosion. Reduce thermal conductivity by approximately 40%.
