Pure Tungsten Electrode Applications
Pure tungsten electrode contains 99.95% tungsten and has the highest consumption rate of all electrodes. Pure tungsten electrode can also provide a clean, balled tip when heated. This shape offers especially good arc stability for AC welding with a balanced waveform. Pure tungsten electrodes also provide good arc stability for AC sine wave welding on aluminum and magnesium. They are not, however, used for DC welding.
Pure tungsten electrode is used extensively in various industries for specific welding applications. The most widely used of pure tungsten electrode is used in AC welding under alternating current.
