I bought a new welding regulator this week (twin gauge Argon) and fitted it today, but I can't get a smooth gas flow from it, it pulses as if it
is opening and closing constantly and makes kind of clanging noise with each pulse 
Question:
Do I just have a faulty regulator (as I suspect) or is there something that can cause this to happen?
While I have no idea what could cause this other than the regulator being faulty, can anyone confirm this before I send it back?
Cheers
Alex
Sounds like a leaking diaphragm to me
Just got some replacement CO2/Argon mix bottles at work . Now there is no need for regulators, just a "jet" in the feed pipe.Don't know if this is the way all mig gas bottles are going but supplier apparently said that regulators are now getting difficult to get hold of.
Don't know if the argon is the same but when i bought my co2 regulator i was told to always have the regulator closed when you turn on the
cylinder or it can damage it inside. Your description sounds like what he said would happen. You probably know what you are doing so please excuse me
for teaching you to suck eggs.
Cheers Ronnie...
ps You can't be too far away from me. We should meet up sometime
yeh...I was told the same thing, and while I wouldn't go so far as to claim that I know what I'm doing 
it was fully closed before I
opened the bottle.
Looks like it will be getting returned in that case 
and probably another argument over why it is broken, something to look forward to then 
Cheers
Alex
PS
Up for a meet anytime Ronnie, I'm in a lovely quiet little village called Larkhall

So when the torch is 'off' what stops the feed line building up to bottle pressure and exploding?
Haven't got a clue, theres a quick release type coupling about the same size as a PCL coupling that has a very small hole through the centre very much like a carb jet. whether or not there is any pressure sensing device inside I don't know. Bottles are supplied by Linde Gas

And now i have to adjust the work pressure
Does annybody nows howe mucht it must be??
