pressure setting for Argon/CO2 mix on mig

[WagonCrazy]

When Mig welding, how much Argon/CO2 pressure do you set your regulator at? Whats excessive?
I seem to go thru this stuff faster than I think I should be.
Have it set at 18 pounds currently...

Mine seems to last forever. I think part of it is that it doesn't post-flow like the TIG argon does. It just turns off and on with the trigger. Not sure what the pressure is set at but I think the gauge is in CFH, not psi. We use 10-15 CFH on our TIG and I think about the same on the MIG.

I think I see L/min on your gauge so it's a flow gauge. The red numbers look like XXX/hr. 15 CF/hr is 7.1 L/min. You're running way too high flowrate.
