Welding regulator
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
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

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?
Tell them about the bent treacle edges!

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

If you've got good hearing
Turn the wire speed off and press the trigger then turn the reg till you can just hear the nozzle hissing next to your ear.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Why turn the wire speed off? If it goes in one ear it won`t come out the other
