I'll have to double check what the gauge measures, perhaps it was 1500. Anyways, i always shut the valve on top of the tank when I was done welding, which should stop the tank from losing anything, which is why I don't understand why when I open it back up the gauge would show less than it did the night before. There is a gauge between the regulator and tank (this is where I am getting my pressure numebrs from ) and then a flaoting ball gauge on the regualtor that goes up when you are actually welding.
