Look at the gauge on the low pressure side of your regulator. If it reads
CFH or SCFH you're in business. If it reads actual pressure you have the
wrong type.


You can use one calibrated in pressure. The MIG will have an orifice
inside that will set the flowrate as a function of pressure. Just get
a 1 qt baggie, adjust your regulator so the welder fills the
baggie with gas in about 6 seconds. That's about 20 cu ft /hr.
