Anyone know anything about this dinosaur? (TIG)

Looks to be a rebranded Miller/Airco machine. Should be a good solid machine. Take the covers off of it and make sure it isn’t full of crud. May be old enough to have an Oiler hole on the fan motor. Lube it if it does. You should see the high frequency points in the lower right. You can fold a piece of 220 grit and slide them together enough to smooth them off if need be. Just going off of memory I believe the point gap should be set about ten thousandths when you are done.
