Is it better for the iron coating of a solder iron tip to leave solder on the end when its not going to be used for while but powered up, or is it better to wipe it clean before it sits hot in its stand for a while?
Air therefore oxygen isnt going to get to the tip with solder on it, but then the stuff in the molten solder may eat it away.
