    Do not reply to this please as work is in progress.

    This Station is designed with specific things in mind.
    It hold two identical Soldering guns together with a hot air gun for surface mount soldering works.

    The Iron's are readily available on ebay.
    Please note that the iron is model 900 as indicated but the ones I had were 926 and the pencil is hakko 903 shown below

    In order to renew the parts and heater, the pencil is taken apart. The two pencils I will be using are these ones. The Tip is a standard hakko one available on ebay too.

    A note on heater...

    there are two types of pencil. One with a
    "3
    Ω Heater with a 50Ω PTC thermistor @ 26°C" which is the one I am using and the Hakko 900 which has the same heater but a much lower resistance thermistor. Use the later in this circuit which I will be showing, and you will end up with a melted pencil. Period.



    The iron handles a variety of tips from very fine tips to spade tips.
    The temperature of both iron can be adjusted individually.


    The Heater is a standard 24VAC 50W Ceramic heater with a in built PTC.
    Heater can dissipated a maximum of 50W and operates on 24VAC.

    The hot gun used was taken from my broken station

    On the top of my desoldering station is the retched one I regret buying.
    And now it is getting overhauled.

    The Hot Gun Assy is shown below.

    I will be doing further test on it will post the results after posting some more detail of the rest of the components.

    Stay glued
