Any _relatively_ inexpensive TIGs?
Have you tried using a blue or green lens?
The best lenses I have ever used, although spendy, are the gold plated.
They REALLY make a noticeable difference, and FYI, I used a 12-14 for Al.
On regular steel, they are a joy to use, and if taken care of properly, last
a good while.
