Of course, I am such an extremist on this, such an advocate of mechanical simplicity, that I thought the automatic choke was a stupid, trouble-prone, unnecessary invention. And my TIG machine is an elderly Lincoln Idealarc 250TIG/250, not even with square-wave, just a big dumb plowhorse. I'm just a crank.
. . . but if this machine ever hits the market and goes a year in the shops of guys like y'all without too many issues, I sure will be tempted . . .
