The higher thoria content in the EWTh-2 electrode causes the operating characteristic improvements to be more pronounced than in the lower content.
- 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
- Size: 3/32"
- Dimensions: 8 x 3 x 1 inches
