    I am attempting repair of my Weller EC2001 Soldering Station. Doe
    anyone have a schematic? The base unit has digital readout, an
    adjustable temperature.

    Just voltage and resistance readings on the 5 pins of station, and o
    the EC1201A [or EC1201P] iron would be helpful. The 28 V output seem
    OK, as is the on-board regulator.

    I think I've got a rough wiring diagram at work. I'll try to remember
    to bring it home.

    IIRC, there is a NTC sensor in the tip that is fragile. If that is
    open, the tip will overheat. I tried to fix ours, but gave up and
    bought a new one for ~$55. A few years before that I had replaced the
    temp control circuit in the base. There was nothing there that I could
    fix, I just had to buy the whole module for ~$80.

    If I had this to do all over again I would not have picked up that $5

    Get a nice used Weller WTCPx, fix what's broken, and use it for a
    lifetime. Much cheaper, much nicer, much more reliable. Just take the
    base apart when you get it and SOLDER the connector pins to their

    I pulled out some weller notes i had from work.
    On the 5 pin connectors, pin 2 & 3 are the sensor and
    pin 1 and 4 are the heater. the sensor was about 22 ohms
    cold and the heater 28 ohms. If either set of terminals
    reads infinite, you got a problem in the head or cable.

    My Email to you bounced.. I have tried to send you a reverse engineered
    copy of a weller
    2002 schematic. I hope it is similar. Email
    me if you are interested. [email protected]
