    Hi... what type of gas? In what mix? I have a tank, approx. 2 feet high, with a 75% argon/25% CO2 mix. I've been using it for a month or two, and it's down to 1500 psi. I don't think the tank size influences the pressure; the larger tanks just hold more gas volume.

    My argon tanks have about 2000 PSI full. ArCo2 is about the same.

    My CO2 tank is about 900 psi.

    Not 200 bar then (3000psi)? Mine normally arrive from BOC with something like 220 bar inside them. 200psi would be empty.

    I got a tank of 75% argon/25% CO2 from my cousin that he thought was full, and it was the same thing; the gauge barely moved off the stopper. Took it to a refill place and they said it was empty. It was a reputable place, been in business for many decades, great reputation from people that use them.

    My argosheild bottle is filled to 220 bar and thats about 3 1/2 feet tall(allthough it's empty at the moment:()
    I got a tank from boc it is a argoshield universal size Y and it was supposed to be filled with 220bar, but when I got it home it only said 110 bar on the gauge, I thought that gauge may be faulty so lucky I have a spare and tried that and that also said 110bar, so it was back in the car to boc for a exchange which the did after putting their gauge on to check it.
    When you are paying a lot of money for a bottle you want to be sure it is full

    As it is liquid, CO2 will always read about 900 PSI until it is just about empty. Then it will drop fast.
