A strange noise from my O/A

[Shedendman]

My oxy/a is making a strange gurgle noise from the torch,like if theres water in it.
Did a bit of light brazing on saturday and noticed it,didnt really think much of it tbh.
This afternoon same thing happening but a little louder than previous
Doing all the setup right,by purging the hoses first no sound then,but when come to light and get a neutral flame the gurgle starts about 10 secs,this is happening with a couple sizes of nozzle plus a 6 hole heating one,torch is a murex sappire lite O set at 10psi A at 4psi on average.
Over worrying to much??????????????

It's not the one way valve in the hose fitting vibrating is it?

Come to think of it,i first though i had a leak from in or around a valve somewhere,but no vibration,interesting though

turn the-acetylene on without lighting see if it makes any noise-iff not turn off and do same with oxy it may be the check valves -there spring loaded and sometimes make a racket in use

Hello Stalwart,

the recommended pressure is 2psi for both so running a bit high on pressure.
