There are some materials that require a change of the type of shielding gas used as well, or an additional "back purge" of gas provided to shield the back side of the weld. Stainless steel being one of them. If the back side of a stainless weld is open to atmosphere it can cause "sugaring" of the weld bead on that side.
I think Tom is underplaying the hand/eye coordination needed though. Or maybe it's just the fact that I don't have any....
I do know that I went through a LOT of tungsten's when I first got my TIG machine.
