Engineered to exact specifications, you can count on these long-lasting electrodes to perform during your most difficult welding application, time and time again. With reliable arc-striking and a low burn-off rate, these electrodes maintain the highest quality of arc while adhering to ANSI and Aussie & U.S Welding standards such as AWS A5.12M/A5.12:2009.
Zirconiated tungsten electrodes (AWS classification EWZr-1) contain a minimum of 99.10 percent tungsten and 0.15 to 0.90 percent zirconium. A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. It is ideal for AC welding because it retains a balled tip and has a high resistance to contamination. Its current-carrying capability is equal to or greater than that of thoriated tungsten.
Under no circumstances is zirconiated recommended for DC welding.
Over fifty years of experience have culminated into these premium quality TIG welding tungsten electrodes, and you can benefit from that experience.
