The tunsgten with the red stripe is slightly radioactive so what extra care should be taken when grinding the point? Radioactive can't be good so should I just ditch the 3 electrodes I have and get some other ones? I read up a bit on http://www.aglevtech.com/About_Tungsten_Electrodes.html. I am new to tig so may be doing quite a bit of sharpening for a while. I am working with mild steel at 1/8 and under for now.

Thanks, Chad

I wouldn't be too worried about it. You're doing more harm to your body if you weld without using a respirator....

We have a good article on our site about grinding tungsten
(tip geometry and the like)
http://www.arc-zone.com/catalog/web_store.cgi?page=library.html&cart_id=

Also, if you're concerned about safety,
http://aws.org/technical/facts/
Article No. 27 has info on thoriated tungsten electrodes.

We generally recommend that if you don't have to use, that is to say its not in a specification, then why bother when there are safer alternatives available.

Hope that Helps!
