Millermatics come with a flow gauge. It measures CFH. If your flow meter is using more gas, I think it may have a leak somewhere. Not that uncommon. CFH is CFH. Generally flow meters tend to be more accurate though.

I've read, though never tried it, that flex core wire used with gas (co2 I think) is a good combo for steel and mild steel with good penetration and little splatter with the right amps etc etc.

Obviously not since this is the regulator that came with my MM 210. I have had to repair it once since I bought the machine in 2001.
This is the Flow Meter that I have tried using and quit because it used too much gas.
There was no leak! With 50 years of professional welding experience that would have been the first thing that I checked.
I braved temperatures in the 40's to go out in the shop to take these pics! My business is shut down until it warms up!

One may have a higher regulated pressure than the other. If so, then you get a larger "puff" of gas when the gas starts to flow. This could account for higher gas use even though both are set for the same CFH. This effect gets worse if you have long hoses between the tank and the welder.

Your picture is too blurry to read what the gauge says. A regulator, flow gauge and flow meter all start off with a regulator to lower cylinder pressure. A flow gauge looks identical to a common regulator but uses a CFH gauge instead of a pressure gauge. A flow meter uses the vertical ball gauge attached to a regulator. You can turn a flow meter down just as easily as a flow gauge. If you really want to see how much gas you're using, Esab makes a flow meter that measures CFH gas flow at the MIG gun. Some critical jobs specify an exact gas flow rate. To measure the amount of gas used, it's measured in volume not pressure but higher pressure generally results in more gas being used.
