Standard Ultimate Shield(R) Gas Trailing Shield. 1/8" (3.2mm) For 22 Series TIG Torches. Shield length: 3 3/16" (8.1cm).
Provides highly efficient secondary gas curtain around the primary gas, which is directly over the molten pool. The secondary systems are engineered to prevent air from disturbing the primary gas. The trailing system delivers gas over the heat affected area as the hot metal traverses out of the primary and secondary gas shields without any interruption of gas coverage.
Designed to Increase Weld-Quality, Consistency and Reduced Post-Weld Clean Up.
