I have a Lincoln 175 SP Plus. It has a regulator that is in PSI, not cfm.
I usually set it for 10 psi unless it's a little windy then 15. What do you
use? Is that anywhere near correct?

You should get a "puff" of gas when your push the button/ and release it.
I have a flow meter on mine, with a pressure gauge.
My flow meter reads 15 cmf at 30psi.
Stick out when pressing the switch is about 3/8"
to much gas, you can see, welds aren't that good, to little gas, weld is
difficult
