Soldering iron to patch tubes?

The idea is just as it seems... melt the rubber to seal the hole.

Anyone done this before? Success?

Won't work. If you have a spare tube that you don't want to repair,
try it and see. There are several issues involved, but the bottom
line is that trying to heat-weld a butyl tube using a soldering iron
is not going to produce the required result.

Hmmm, what kind of flux do you use?

tubes, and "hot patches" were routine? What was the theory there?

Those are for the old, natural rubber tubes. Today's are syntheti
butyl and work fine with rubber cement

Essentially the heat is applied to cure the glue to hold the patch.
This will give maximum strength much more quickly than cold patching
where you might need to wait a day or two for full curing to occur
(hence the oft-quoted recomendation to use a spare tube rather than
re-insert a freshly patched one if you have a puncture).

"Hot patches" are still used for tubeless tyre repairs in automotive
applications, applied to the inside of the tyre rather than the
outside of the tube so they are not as visible.

That is a silly question. Everyone knows inner tubes are TIG welded.

Do you have to fill the tube with inert gas?

Unfortunately we're starting with a punctured tube. We have to patch
it conventionally first so it will hold the inert gas.

None needed. The soldering iron flux the tube all by itself.
