I have a tank of Argon - 100%, and a tank of CO2 - 100%.

Ernie's answer to Don Foreman's recent thread suggested 25 AR and 75 CO2.
So is there some kind of mixing valve where I could hook up the two tanks
and get blended gas out?

This would only be for occasional use, I'd just get a blended tank for a big
job.

Do you have regulators and flow meters for each tank? If so just connect
the lines out of the flow meters to a "y" and then on to your solenoid
valve. Then adjust the flow meters for the desired ratio.
