Less spectacular improvements than I was hoping for.
HiFreq is 'somewhat' stronger, but on Alu. it still does weird things.
It acts 'cold' even on high range.

There is not an abundance of cleaning action, and the puddle is sooty.
Makes no difference if I clean everything rabidly, or not.
Then there's the ever present weirdness where the puddle seems to 'vibrate'
or hop up and down about .040 or so, plus the arc has that buzzing sound that
goes along with the vibrating. When it's doing that, it acts real cold, sooty and
hard to get the puddle to even get shiny.
3 things I suspect:
1.Torch is sucking air, or bad bottle of Argon.
2. My aluminum service wire is not delivering enough amps, or somehow primary
voltage is dropping off.
3. Internal problems.......other caps, or ????

then other days......what I described above.
I have an old air cooled Linde torch around someplace, I will try that just for chance.
Any ideas what the problem could be?
