Well, high melting point solder is a double-edged sword when you are doing PCB work. Higher temperatures will quickly lift the traces off your PCB, something to keep in mind.
FWIW, I've soldered a ton of resistors into MTH smoke units with my standard 63/37 tin/lead solder, and I've never had one melt down. There are really low temperature solder types that melt at less than 300°F, those might actually be problematic.
