EWTh-1 tungsten color band identification.

Explanation:
The key idea is that color bands on tungsten electrodes identify the alloy type. For EWTh-1, the yellow band marks this thoriated tungsten, helping you quickly distinguish it from other tungsten types that use different color codes. This identification is important because EWTh-1 is chosen for its arc starting and performance characteristics with DC and AC in various steels. The other colors correspond to different alloys or diameters, so they don’t apply to EWTh-1.
