a single stage regulator will change its settings as the presher in the tank changes.
think of it as ajusting a garden hose at your house then going to a frends if the presher is diferent the flow will be diferent, so as the tank emptys the regulator will need to be reajusted, just as it will need to be when put onto a new full tank. the larger the tank the longer it takes to see the change acure, in smaller tanks presher change is faster so more ajusting will be needed.
the only way around this is to get a 2 stage regulator, but they are verry big $'s
nothing wrong with the gage its just the way they are.
thanks for the help
......or..........

summer is here, plant a tree. if you don't have space or time to plant one sponsor some one else to plant one for you. a tree is an investment in our planet, help it out.

I have another question about regulators. I have a Harris that has 2 gages, one for the pressure of the tank and the other for the flow rate of the gas marked in cubic ft. per hour. It has one scale for argon and one for carbon dioxide. My question is does this mean this regulator is Ok for 100% carbon dioxide. I don't do that much continuous mig welding, but it has not frozen up as far as I know. Several years ago, the guy at the Airgas store set up my whole mig outfit so I hope he gave me what I needed.
Thanks

When I bought my welding outfit, I didn't know enough to ask anything. I just wanted to learn to weld.

Yes it's ok to use for 100% CO2, or for that matter any mix of CO2 & Argon up to and including 100% Argon. If it's not icing up, and you like using CO2, then I wouldn't worry about it. I much prefer using C25 for mig but thats just me.

This is a perfect example of what we don't need on the forum. Originally Posted by Frank865
