Description
The EWTh-2 electrode with higher thoria content shows more significant improvements in operating characteristics than those with lower content. It offers about 20% higher current carrying capacity due to the additional thoria.
- For AC welding, you can achieve balling by using DC electrode positive before switching to AC.
- During AC welding, the balled end doesn't melt, but the emission isn't as good as that from a liquid ball on an EWP.
- Size: 1/16'
Using this Blue Demon EWTh-2 thoriated tungsten is easy. First, if you're doing AC welding, start by welding with DC electrode positive to get the balling done. Then switch to AC for the actual welding. When it comes to current, keep in mind it can carry about 20% more current because of the extra thoria. As for maintenance, store it in a dry place to avoid any damage. Also, always handle it carefully as it's a precision tool. And be aware that during AC welding, the balled end won't melt, but the emission might not be as good as some other types. That's it! Just follow these steps and you'll have a great welding experience.
