Description
The EWTh-2 electrode with higher thoria content offers more significant improvements in operating characteristics compared to those with lower content.
- Extra thoria boosts the current carrying capacity by about 20%.
- For AC welding, you can form a ball by using DC electrode positive before switching to AC.
- During AC welding, the balled end won't melt, but the emission isn't as good as that from a liquid ball on an EWP.
- Size: .040
Using this Blue Demon 2% thoriated tungsten electrode is straightforward. First, if you're doing AC welding, start with DC electrode positive to create a ball at the end of the electrode. This helps in the welding process with AC. When it comes to the current, thanks to the extra thoria, it can handle about 20% more current than some other electrodes. Keep in mind that during AC welding, the balled end won't melt, but the emission might not be as great as a liquid ball on an EWP. As for maintenance, store it in a dry place to prevent any damage. And always follow standard safety procedures when using it for welding.
