Do GTAW-P processes use the same tungsten electrodes as GTAW?

Explanation:
In GTAW-P, you still rely on a non-consumable tungsten electrode to establish the arc, just like in GTAW. The plasma version adds a constricted nozzle and high current to create the plasma jet, but it doesn’t require a different electrode material. Therefore, the same tungsten electrode types used in GTAW—pure tungsten or doped varieties such as thoriated, ceriated, or lanthanated, chosen for current and material, are also used in GTAW-P. The main differences are in the torch design and operating conditions, not the electrode material.
