What pressure for MIG regulator?

Just wondering. I tend to use it at around 10 with no wind, and 15 if there is air movement. What's correct? 86/14 argon/CO2 mix. Lincoln 175 SP + .030 steel wire. 220v.

argon mixes set you reg at 30to 45 cfh chuck

Why does mine work so well at ten to fifteen? At that rate, my 80 cf tank would last less than two hours. Doesn't sound right to me. YMMV. Gotta look at my reg, and see if that is 10 psi. But I get a lot more welding time out of it than that.

One of you is talking about pressure, and the other about volume (psi vs cfh.)

And so far none of you has posed a problem in language someone as dumb as me can understand!

Hey Steve,

I've got the same machine and the regulator has two scales...One is CFH Cubic Feet per Hour -- the other scale is l/min - Liters per Minute....I bring this up cause when I first got it I was setting it to 25 - 30 (per this group) Only problem was that I was reading the l/min scale which translated to about 50+ CFH.....Needless to say my first bottle or two of gas went REAL quick....Then I came to my senses and actually read what the gauge said on it.

If you are setting yours to 10 l/min you are actually right around 20 CFH which would explain why it works ok.....

set it at 20 Cf/hour for small gun like the one you got (with your SP

175.)

I use a miller version, M10 gun at 20CfH with a C25 gas and bump it up to 25 CFH for the bigger M25 gun

Made a microwave shelf for the cabin today out of some round rod that looks like tree limb, and some nice embossed flat bar. Looked at the gauge, and noticed it had l/min and CFH.

Yes, I have been using it at 10 l/min, so guess I am close.
