Zirconium-Dioxide-Doped Tungsten Electrodes Containing Less Than 1% ZrO2. The EWZr-1 electrode is a tungsten electrode containing zirconium oxide, referred to as zirconia. This electrode is preferred for applications where tungsten contamination of the weld must be minimized. This electrode performs well when used with alternating current as it retains a balled end during welding and has a high resistance to contamination. Not recommended for DC applications. Zirconiated tungsten produces an extremely stable arc that makes for a higher resistance to tungsten spitting in the arc.
