Butane soldering irons
- No exposed flame, although there will be some heat coming off of
They don't suffer from overheating as standard butane lighters do,
they are designed to run a long time without failure. Although in
an enclosed space, you will need to be very careful about heat
I'd think running it on the lowest setting would be sufficient,
especially if you couple it to the boiler. Perhaps a copper tube
soldered to the bottom of the boiler, sized so the end of the
soldering iron fits snugly within. Running on low, it should never
reach soldering temp. It might still be wise to use a higher temp
solder to attach the copper tube, such as a silver bearing solder
or lead-free solder.
