I use a soldering iron tip with a regular propane torch. The tip
attaches to just about any torch with a setscrew. Slip it over the
end of the torch, tighten setscrew. I haven't looked for them
recently. I bought this at a local hardware store 30 years ago for
about $2 I think. It gets hot enough to solder #12 copperweld at 100
feet above ground with an air temperature of zero and moderate
breeze. I could have been content never having acquired that
particular bit of knowledge. ;-)
