I’m having trouble with my hand-held propane and Mapp gas torches,
since I changed tanks.
My Mapp gas torch head was working fine (for the last 25 years)
until I recently put it on a new tank of Mapp gas – now it will
light when barely turned on, but then blow itself out, if I turn up
the pressure at all or tip the tank forward to use the flame for
I bought a new propane torch head (Worthington Pinpoint model), put
it onto a new tank of propane, and tried to light it. It is hard to
light and won’t stay lit. I also tried it on an old tank of propane,
but it didn’t work there, either.
I have used propane and Mapp gas without difficulty for over 25
years – can anyone suggest what the problem is now?
[I have an old self-lighting propane torch head which is working (as
is my acetylene torch), but I don’t use it because its splayed-out
propane flame shape is wrong for my soldering.] I thought it might be
the Worthington brand of Mapp gas and of propane, so I bought a
different brand at Sears, but the problems remain.
