Plumbing solder is typically 50/50 tin/lead (or even stranger, now that
they're trying to use lead free solder for plumbing) which melts at a much
higher temperature than 63/37 tin/lead (so called eutectic). However, the
real problem is the flux... plumbing solder doesn't have any, since you
usually swab or brush on the flux (some fairly corrosive stuff that will cut
through the copper oxide.. Ammonium chloride or zinc chloride are popular).
Electronic solder usually uses rosin, or some similar substance for a flux.
This is a good thing, because it is non-corrosive, so the flux that
inevitably stays behind won't slowly eat away at your delicate little wires.
The flux is usually in the core of the solder, so it's right there when you
I would imagine that you can find 1 and 5 lb spools of decent electronic
solder on Ebay... Or, are you looking for hundreds of pounds for your wave
