WZ8 
Zirconiated:
Zirconiated tungsten electrodes (AWS classification EWZr-1) contain a minimum of
99.10% tungsten and .15 to .40% zirconium. A Zirconiated tungsten electrode
produces an extremely stable arc and resists tungsten spitting. It is ideal for
AC welding as it retains a balled tip and has a high resistance to
contamination. Its current carrying capability is equal to or greater than
thoriated tungsten. Under no circumstances is zirconiated recommended for DC
welding.
