Hypertherm PowerMax 85A, running at 85A unshielded. We are fortunate in that one of our coaches is a Hypertherm engineer and can recognize when things aren't right.
Having him help out has been the difference between "man, this this sucks and does not make usable parts" and:
Seriously, the difference in 1/8in aluminum was +/- 0.03in tolerance if we were lucky and +/- 0.010-0.015in tolerance quite reliably. We don't have 1/4in cuts from the 'dark days'.
We still re-drill holes to clean them up though.
