Zirconated tungsten electrodes perform best in AC welding, especially under high load current. These tungstens can retain a balled end when welding, which results in less tungsten permeation and good corrosion resistance. It balls up well in AC welding and has a more stable arc than pure tungsten. Especially with excellent performance in high load AC welding, it is not replaceable by any other electrodes. It also resists contamination well in AC welding.
