Pure Tungsten Electrode (WP)
Pure tungsten electrode features an exceptionally high melting point and low evaporation loss, offering a reliable and economical solution for AC welding of magnesium, aluminum, and their alloys.
Pure Tungsten Electrode:
Pure tungsten electrode has very high melting point and boiling point, the evaporation and burning loss is less than other tungsten electrodes. But electron emission of pure tungsten electrodes is not as good as others and so it is not good for keeping stable arc. Besides, the current bearing capability and antipollution capability is low. Pure tungsten electrodes suit for magnesium, aluminum and alloy.
