Oxy Acetylene set up

[trooper1954]

Hi all,
I have inherited an oxyactylene kit with two Victor regulators and a few torches that have all been recently serviced by a reputable welding supplier.
I hooked everything up today, and found I am leaking on the oxygen side at the rate of 100psi per 5 seconds, yet when I spray all connections with soapy water there is no sign of a leak.
Anyone any troubleshooting steps I should take from here....I'm stumped!!

Bad hoses?

You should be able to hear a leak like that. regulator? Gauges? Is the torch leaking?

If you release the regulator pressure control. does it still leak?

If so, the internal regulator valve is leaking

The gas is probably coming from the pressure release valve.

Thanks all....yes Jack...pretty sure its coming from the release valve...is that replaceable if taken apart?

It is replaceable but it is not clear if the release valve has failed or the internal regulator valve is not closing properly.

More often, it is the latter and it may be because there is dirt in the valve (I think you said the gauges had been rebuilt). I'd get it serviced if you are not comfortable doing it yourself.

Get yourself a new oxygen regulator. When they fail like this and pop the relief valve, count your lucky stars that it didn't blow up in your face and move on. FWI, servicing a used oxygen regulator costs more than a replacement, and I would not advise servicing it yourself. The oils from a single errant fingerprint inside could prove fatal.

Thanks rlitman....good advise to be sure....I won't be medaling with it!!!

I did attach another regulator that I had, and there now appears to be no leak...but I have two other issues.
In the attached photos, one is of an acetylene cylinder shut off valve.....it seems to be seized!! I tried turning it on with the little key that fits over it, but it promptly stripped that out, and I cant get an adjustable wrench to maintain a good enough grip to turn it. Would appreciate any suggestions on this?
Secondly, the replacement regulator has a different set of number on the gauge.....is this suitable to hook up to the Oxygen side?
Appreciative of any help.

I suppose it would be helpful if I remembered to attach the photos!!!!!

And the text?

so you've got an oxy/acetylene set up with a B Tank for acetylene but no regulator?

 

[The Cobbler]

merged 2 threads so 2 previous posts probably no longer make sense. OP had started a second thread with the pictures shown in post 9

 

[The Cobbler]

are you turning it the right way ? counterclockwise?
is it by chance fully open and that's why it won't budge?
what sort of numbers are on the new Oxy gauge?

Personally, I wouldn't muck about with a stuck acetylene valve, I'd exchange the cylinder.

The replacement regulator shown is designed for a much higher delivery pressure than you need. Get a replacement that is designed for the job.
