Lou,

I echo several prior comments and add that in many of the IPC7711
procedures it states, "Start with a tip temperature of approximately 315C
and change as necessary"

I add further from our own Basic Soldering Guide, "Controlling soldering
iron tip temperature is not the key element in soldering. The key element
is controlling the heat cycle of the work. How fast the work gets hot, how
hot it gets, and how long it stays hot is the element to control for
reliable solder connections." Visit www.circuittechctr.com/guides/7-1-1.htm
for more information.

hand soldering, some people say 700 F, some 750 F.  My suspicion is there
may not be one temperature to use all the time.  Any comments would be much
appreciated.
