[Elecraft] Hakko 936-12

[Greg Beat]

Ian -

For a variable temperature soldering station -- and using 60/40 (Sn/Pb) 
solder -- stay within the range of 650 to 750 degrees F (345 - 400 degrees 
C).

Personally, I always set one to 700 F degrees (370 C) --- since I learned my 
techniques in 1970s with the Weller TCP series with 700 degree tips.

I do NOT recommend 800 F degree tips or temperature settings, burns up tips 
faster.
Really only useful for SOME lead-free solders -- and you must have excellent 
soldering techniques (be quick) -- not to lift traces, etc.

Get the proper MASS and PROFILE for your solder tip -- that matches the 
solder joint -- these are far more important to proper heating of the joint 
for solder flow -- than "dialing up" a higher temperature (which is the 
common mistake for the beginner).
