Zirconiated Tungsten Electrode
Details
Zirconiated tungsten electrode boasts a fine performance in welding under the condition of AC. Zirconiated tungsten electrode shows superior performance especially at high load current, which is irreplaceable by other electrodes. The end of this type of tungsten electrode may remain rounded and spherelike to reduce tungstenizing, and show superior corrosion resistance. Similar to pure-tungsten electrode, zirconiated tungsten electrode is only suitable for welding operation under the condition of AC.
