The XTRweld Pure Tungsten Electrodes are ideal for GTAW (TIG) welding applications. Pure tungsten electrodes contain 99.50% tungsten, have the highest consumption rate of all electrodes. These electrodes form a clean, 'balled' tip when heated and provide great arc stability for AC welding with a balanced wave. Pure tungsten 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 thoriated or ceriated electrodes. Pack of 10 tungsten electrodes.
