Didn't work, what kind of hat were you wearing? Ok, I'm being ridiculous,
but like you say, if CO2 is hotter then perhaps you can turn the amps down,
or maybe the flow up, or have it cooled otherwise... I dunno, but I doubt
that the best method is any more than someone's trial and error that they
had success with.

I suppose you could spray paint by filling your cheeks with paint and
then sneezing.

Trial and error tends to produce best results with a method that has
technical advantage for one reason or another. That isn't to say
that acceptable results can't be obtained with alternative methods.

I have visited a number of restoration shops and body shops. They all
run Ag25, none that I've seen run straight CO2.

I had a commercial welder over to the house yesterday, and he was
wondering how long that tiny little bottle of gas on the back of my Mig
lasted. I told him...about 6 months. He backed up, gave me a really
funny look and a sneer. Then he read the lable on the bottle..and
raised his eyebrows..asked...can you really weld with straight Co2?????

I fired it up, laid out some scrap and handed him a hood and the gun,
and told him to have at it.

He ran some beads, beat some iron..and mumbled that it worked pretty
damned well..and asked if Id told anyone about it?

Chuckle.....

Its not as common in shops as one would expect, which I find really odd.

One could not be a successful Leftwinger without realizing that,
in contrast to the popular conception supported by newspapers
and mothers of Leftwingers, a goodly number of Leftwingers are
not only narrow-minded and dull, but also just stupid.
