Tungsten color for 2% ceriated?

Explanation:
Tungsten electrode color coding tells you its dopant and typical use. For 2% ceriated tungsten, the color is orange. Cerium oxide improves arc starting and stability, making this electrode versatile for welding nonferrous materials and suitable for both DC and AC applications. Gray indicates zirconiated tungsten, which is a different composition. Green is pure tungsten, red is thoriated, and blue is lanthanated. So the orange color is the one that denotes 2% ceria.
