I’m having a weird problem with a single stage acetylene regulator I
just purchased for use on an MC tank with my Smith Little Torch. I
installed the regulator following standard protocol, but am having
strange fluctuations in the dials and gas flow. The second dial
(which regulates the actual gas flow) shows the gas pressure to the
torch going up and down from 5 pounds of flow to 2 pounds of flow.
Sometimes it even shows no gas flow to the torch and yet the torch
is obviously getting gas and working just fine. I don’t know if the
diaphram is sticking or what, but it makes for an erratic flame and
I’m concerned about safety.
I’ve also had a couple of occasions when I shut down my torch and
totally bled the lines as usual, only to come back out to the shop
later and find the first indicator dial registering as if I’d opened
the tank to the regulator, (no gas flow through line to torch,
'though.) I’m starting to suspect that I’ve either gotten hold of a
bad regulator or my shop must have spooks. Any ideas?
