Tungsten Electrodes, 2% Thoriated, Set of 10

Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. These non-consumable electrodes come in a variety of sizes and lengths and are composed of either pure tungsten or an alloy of tungsten and other rare-earth elements and oxides. When AC welding balling can be accomplished by welding with DC electrode positive prior to welding with AC. During AC welding the balled end does not melt and so emission is not as good as from a liquid ball on an EWP.
