Tungsten Electrode Technical Resources & Welding Guides
Practical guides for buyers and welders: how the color code system works, how to choose between AC and DC electrodes, and how to grind a tip that lasts.
TIG Tungsten Electrode Color Code Chart
Every type and its color under AWS A5.12 / ISO 6848 — identify WP, WT20, WC20, WL, WZ8 and WY20 at a glance, and see what each oxide addition changes.
