OK, so we are left with two options:
1) Practice soldering with a bare butane flame. The pencil torches can be
adjusted (after a short warm-up) to a flame small enough to do the
job.......but that IS an acquired skill.

When I was working for Hughes Aircraft Company on prototype
electromechanical systems back in the late 1960's, one lab had a neat
little gadget called a "water welder".

It somehow used electricity to generate a flammable gas that came out
of the tiniest hole in the tip and I could use that flame to solder
sheet brass into compartmented prototype electronic chasses...
