Current _is_ amps! Heat derives from current through resistance.
It's a mathematical product, so as either goes up so does the heat.
(Amps times amps times resistance, actually.) Solder is used to
_seal_ and secure a low-resistance mechanical connection between the
copper wires, very little current is actually preferentially going
through the more resistive lead as compared to the copper, unless the
mechanical joint is poor. In no way should any properly soldered
joint get hot enough on its own to melt the solder. If it did, it'd be
melting the insulation in the area too, maybe even starting a fire.
