Zirconiated Tungsten has good performance in AC welding. 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 containation well in AC welding. Zirconiated Tungsten is most commonly used for AC welding of aluminum and magnesium alloys. Please see its technical data sheet in our website.
