[TheForge] tig setup- health hazard?

[James Binnion]

There are several types of tungsten electrodes that don't have thoria 
in them . Zircona, Ceria, and some proprietary types. I have switched 
to the ones from arc-zone.com their 2% Lanthanated types are supposed 
to be a good non-radioactive replacement for the thoriated ones. I 
don't see any difference in performance between them , but I am not 
welding high tech stuff so your mileage may vary.
