    What temperature do you use for :
    1) Soldering
    2) Desoldering

    I have my iron and hot air tips both set for 300 °C as R!f@@ does when working with leaded solder. I have not done enough hand work with lead-free to have a temperature recommendation.

    I use fluxed solder wick for desoldering.

    300 ° sounds " ballpark " though if you are soldering components to PCB's , you want your iron hot enough to be able to make a suitable connect in less than one second dwell time.

    Desoldering ? for larger items -- 2 watt and up resistors, To-3 transistors, rectifiers, or transformers. I clamp my subject PCB into a " spare hand " modified to hold a motherboard rigid..........pointed toward a large cardboard carton.

    Melt the joint, and blow the solder off with a pulse of compressed air into the box...... this gets the objective component loose, and serves to instantly [ or close ] cool the lead so as not to cook the component....... I do a lot of component salvage :rolleyes:
