is this welding electrode made of tungsten?
hi,
is this welding electrode made totally of tungsten or is it only the tip which is tungsten?

thx. Alf.
The red color is applied to identify electrodes that have about 2% thorium added (mixed evenly throughout, not just in the tip). Pure tungsten (99.50%) electrodes are identified with a green marking on the tip. Other colors identify other compositions.
