There is a screw valve on the torch, Ted, but with the higher
pressure from the tank, the pulsing is greater and faster when I
open the torch valve. I can light the torch, and the flame gets
blown out on the next pulse. Repeatedly. I have not had this
problem with other regulators, which is why I asked if other
jewelers have a favorite regulator brand.
Now youve tried that and eliminated it as a possible cause, pulsing
regulators seem to indicate something is sticking inside.
Regulators are relatively simple inside, the pressure increase screw
outside pushes down onto a spring thats one side of the diaphragm,
on the other side is a valve sometime a cone in a depression or a flat
Id be inclined to ask a car mechanic who has good experience with
taking stuff to bits to dismantle it to have a look nd see.
It could be a bit of dirt thats got stuck in the valve when you
One should always crack open tanks whenyou first get them full to
blow out any dust in the threaded hole where the regulator screws in.
To dismantle them yourself youd need some big spanners or wrenches!
and a decent bench vice.
Its most unusual for the diaphram to fail.
