Gas flow setting for Mig welding?

[Jemo]

What flow rate do you use when you're Mig welding patch panels with 75/25? I got my tank refilled today and forgot what it was set at. :confused:

15-20 cfm ought to do it. You'll know if it's not enough - the weld will be dirty with a bunch of splatter. More than enough just wastes gas, there's no increasing benefit to "more than enough".

Rick, thanks for the fast reply. Can you hold on a minute and let me go out there and try? My regulator is kinda funny. It's at 30 right now and when I turn the dial to lower it, it doesn't do anything.

Thanks Rick. It's working.
