Blue Demon TIG Welding Tungsten Electrodes, 2% Thoriated, RED, EWTh-2, 5/32 in x 7 in 10 pc pack, (TE2T-532-10T)
- The additional thoria provides about 20 percent higher current carrying capacity
- 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
