Tungsten pin is for the application of making electrode of flash lamp in camera, sodium lamps, halogen lamps, metal halide lamps owing to high strength at high temperatures of tungsten.

Tungsten electrode pin contains 99.50 percent tungsten, having the highest consumption rate of all electrodes and typically are less expensive than their alloyed counterparts. Tungsten electrode pin forms a clean balled tip when heated and provide great arc stability for AC welding with a balanced wave.Tungsten electrode pin also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium. It is not typically used for DC welding because it does not provide the strong arc starts associated with thorium or cerium electrodes.
