Pure tungsten electrode is most widely used in AC welding; When pure tungsten electrode is heated, the welding ball becomes sharp to provide a balanced waveform AC welding, and the arc is stable; Pure tungsten electrode also provides good arc stability for sine wave AC welding of aluminum and magnesium.

Production Process: Mixing, pressing, sintering, forging, cutting and polishing
