hey Mike...

yes you are right...   Thorium does make the tungsten  welding "rod" more 
"viable" in keeping the arc going...   but unfotunately...  most welding 
supply places only offer the thorium/tungsten rods    yes  we use what is 
the most available product on the local market...   if one can get PURE 
tungsten, that is the best choice so far other than pure diamond rods( 
which I have NEVER seen..)     tungsten carbide is the next best material 
to get ( drill blanks or various other shapes for milling cutting 
etc)   then we move on to copper ( (due to its wonderful heat disapation 
qualities but low vaporization rates...  makes a great laser ((copper 
bromide))  pretty green color) great at vaporization , then stainless and 
then most ferrites ( iron based metals)   your lower molecular weight 
metals really "brighten "up your life  lithium, aluminum, 
magnesium...  better have a class 3 fire extinguisher on hand
cuz you will need it....
