Do you promise that you won't use the same soldering that you use for
plumbing. : )

Not the same soldering as for plumbing? What else?
Just curious ;-)

Here, in the US, copper pipe is soldered together. The plumbing solder used
to be something like 50-50 tin/lead with an acid flux core....

Hi Frank.
You didn't see my smilie? Hmmm?
In germany soldering for copper is somewhat 70/30 tin/lead -much more
tighter than 50/50. 50/50 is only used for repairs on old lead-pipes
wich are no longer used for new pipes since decades here and it has the
flux core in it and looks like VERY thick electronics solder. It's very
tricky to solder this over head. I learned to handele this more than 20
years ago... :-)
On copper we use acid flux with very fine solder gravel in it wich is
brought to the copper skin with a brush before putting the copper things
together. You will have the copper tinplated when heated only without
adding any additional solder.
For electronics I prefer thin electronics solder with 0.5mm (0.02") in
diameter with my temperatur regulated soldering station. Also have 1.0mm
in use for bigger parts like cable connectors or repairs on car-electrics.
