What color is the EWCeO2 electrode described?

Explanation:
Color coding for GTAW electrodes helps you quickly identify the dopant and expected performance. EWCeO2 means tungsten doped with cerium oxide (CeO2). In the standard color scheme, cerium-doped tungsten is orange. That color signals the electrode’s characteristics, such as easier arc starting and stable current control, suitable for various metals and AC/DC use. So the described EWCeO2 electrode is orange. Green would indicate pure tungsten, and other colors map to different dopants, but they don’t apply here.
