Jeff, have taken some short classes on tig, understand aluminum can be a pain,be carefull of contamination, was told on the tungsten to ( ball the end) strike an arc with tip and let produce a small ball the diameter of tungsten, when tig steel to have a pointed end on tungsten. Perhaps I should've tried smaller tungsten. Do appreciate the help. I don't tig to often,however I do think its kind of fun to try.
