Default Re: Acetylene regulator

Always back the adjustment it will help get a longer life out of the diaphragm which might be the only thing wrong with it. Take it apart and check the diaphragm for cracks. I have made diaphragms for my air regulators which are about the same thing from brass shim stock. I have seen plastic diaphragm's in regulators but all of mine have brass ones. I even made one out of a Gal thinner can a couple of times.
