hi there,
in the welding electrode the thorium is there to help sustain
the sharp point needed for dc welding . a zirconiated electrode is much
better at maintaining a ball shape end. the content isnt down to power
handling.
i may be telling you what you already know but just thought i would put in a
welders input.
i dont think you wil benefit from anything except that you dont want to
grind any heavy metal dry or burn it unshielded(inert gas)
cheers
colin
