750-800 deg. F.
With a large tip for doing motors and batteries.

The Weller 40watt iron from Sears works very very well, and its only around $20. Not a good choice for circuit boards though, unless you like to hear them sizzle....

Standard 60/40 solder melts somewhere around 190 C.
300 C is enough for all your soldering needs. Some people like to use lot more heat, up to 500 C, but that much heat vaporises the flux from the solder and gives you weaker solder joints with lot more resistance. It also destroys the point of the solder iron in very short time. 300 C is enough, but you need some wattage behind it.
I personally use Solomon SL-30 for all my soldering needs except batterys. I use professional gas iron with 10 mm. chisel tip for soldering batterys.
