Cant figure how to post a question here however lets try this. If CO2 liqufies at 800PSI and an argon co2 gas bottle has a mixture of 75/25 and is at 2000psi then does'nt the CO2 stay liquid at the bottom untill the pressure goes below 800 PSI and therefore you are welding with pure argon for the first 2/3ds of the thank and then moslty CO2 for the rest of the tank?
