> Even if the resistivity values of the copper and solder are similar (I'm pretty sure they're at least in the same order of magnitude), you'll still end up with the same amount of current running through the copper wire and the solder.
And what's the problem with that? The resistance of the solder will be minimal (as you say yourself, pretty much equivalent to copper), so the voltage drop and heat production should both be low? Am I missing something?
I mean, I'm pretty sure there's solder connecting the copper wire to the PCB of any PSU in my house, all running at 230V.
