[Amps] 3-500 / 4-400 cooling (09/10/2005)

It sounds like you have solved the problem.

Another good suggestion has been posted here before and that is to 
resolder the pins with silver solder. An alloy of 95% tin and 5% 
silver has a significantly higher melting point. This solder is 
sometimes supplied in a non rosin-core form, so be sure to apply 
rosin if that's the case.

The fundamental flaw is that the pins should never have been 
terminated with a soldered connection in the first place. A weld 
would be much more appropriate.

Does anyone know of a manufacturer which welds the pins?
