[Shop-talk] Oxy-Acetylene for soldering copper pipes?

[doug at dougbraun.com (Douglas Braun)]

Hello,

I need to solder some 1-1/2" bronze drain pipe fittings like this:

in a sort of tight spot. I have one of those common Bernzomatic
propane torches, but I am worried that I'll set the house on fire
before I get the joint hot enough.  I also have a mini oxy-acetylene
set, with #0, 1, and 2 nozzles.  Could that do a better job?  Or is
oxy-acetylene simply too hot for soldering?  Could I end up melting
the pipes, even with a small flame?

Thanks,
Doug
