Normally when i finish welding (tig) i close the valve on the bottle put my foot on the pedal and release all the gas left in the pipes. then i got thinking that this was wasting the gas so i tried leaving it in one night, i still closed the bottle off but when i went back the next day it had all gone out of the pipes.
is this normal or am i missing something? i've tried a bit of water and fairy liquid on all the connections but cant see any bubbling anywhere
any advice appreciated
