Re: Brazed, Soldered or What?

["George A. Traganos" <gat@massed.net>]

Hi Mike, Most motors & generators use silver solder. It takes higher heat
than regular lead tin solder but flows just as well. Regular solder is good
for the electrical connection but has no physical strength & will melt when
the motor gets too hot. George Traganos
