project. Shame to throw it out, but I would like to read the temperature.

I found several schematics for different models. Never did find the one
that matches mine. I opened it up and it seems there is a ceramic board
with surface devices on it. Almost no user replicable parts. Atleast for
my skill level. I was hoping it would be the discrete parts. I can work
with them. Oh well, it was free and is a good soldering iron even without
the display. I do have a couple of spare parts for it also.

Hi Ralph,

In my surfing, I found this reverse-engineered service manual for the
EC2002: http://www.geocities.com/bswadener/t...er_EC-2002.pdf or
http://tinyurl.com/5ff6qx (PDF, 372 KB). It may be of use to you and
others.

Thanks for sending that Bryan. It is too bad for me that is not the one I
have. From the outside it looks like it, but inside it is totally
differant. There seem to be several modles that look similar on the outside
but differant inside. The one I have has a C after the 2002.

Ralph-

Take a look at
http://bama.edebris.com/manuals/weller/
where the EC2002 and EC2002m are listed. Perhaps one of these will be
closer to yours.
