I have an acetylene take with two pressure gauges. Recently, the
left hand gauge (which I believe monitors the pressure in the line
to the handpiece) gradually increases the pressure reading
overnight. I bleed the line each time I’m done for the day, dial
down the pressure valve, and have checked for leaks.
Initially the pressure would only go up a bit. Today it was almost
at full pressure (into the red) from evening to this morning. I
rebled the line. There was a slight odor of the gas, but not like
when the tank is full on.
Any thoughts on what is going on? And what I should do for safety?
The tank is in my garage–it does get cool at night here. then warms
up in the day.
I would appreciate any advice. Thank you.
