As you will find in my "Basics of Basics" on MIG welding,
(Click here for the Basics) "25-30 cubic feet per hour or 3-4 PSI." This is right from the AWS (American Welding society). First things first, does your MIG have a "Flow" meter measureing guage or a PRESSURE guage?
If it's measureing flow set it at CFH or is it pressure at PSI?
And I just noticed in my article it says cubic feet per MINUTE instead of HOUR! I'll have to correct that.
Anyway, look at your guage and see what it says you are measuring.
