I was doing a little soldering Sunday night and noticed the oxyen
pressure had gone from about 5 psi to around 20-30. I closed the
oxygen tank value, bled the line, and then noticed that even with the
tank valve shut as tight as it would go, the pressure was still
My torch is a Meco Midget which developed problems almost
immediately with its Uniweld propane regulator, which had to be
replaced. So at first I thought it was the oxygen regulator’s turn
to go. But with the tank firmly turned off, there should have been
no more problem, unless the tank itself was leaking.
The oxygen tank was recently filled (i.e., swapped out) and
originally read around 2000. Within an hour, it had gone to zero. I
kept bleeding the line because I didn’t want there to be a problem on
the hose end.
I’ve never run into this before, so do you agree that it was a
faulty tank? Or could it possibly be the fault of the regulator? I
can’t see how, as nothing should have been happening when the tank
was shut down.
