Kees, yes, it was a cutting torch. I use propane instead

The top of the tank was pretty decent as far as dents.
The vise kept the flat top from "bulging out" from the
air pressure. Not sure the magic number as far as
air pressure. All I know is that too much might be bad.
I would think air pressure would be a variable depending
on the design and shape of the tank.
