I used to work for a company (ARCO Oil) that used a bunch of those. Weller
closely guarded their schematics and even now they will not release them.
We sent them in for repair but they charged about as much as to buy a new
one. Here is what I found over fixing a dozen or so.
1) The wire nuts came loose inside
2) Intermittent wires in the cable going to the soldering iron. Flex the
cable while ohming end to end.
3) The surface mount electrolytics go bad. These were MOST of the
failures and I ended up changing all of them in the rest of the 25
irons we used over about 3 years.
4) The cheap temperature set wire wound pot gets worn out.

Most of the parts in this unit are consumer rated parts and are available.
Never had any problems with the ceramic boards in the units or with the
printed resistors on them. Had a couple of chips fail. It's an A to D
with a seven segment driver built in. They are available still.

Other than the above, they are really a darn good soldering iron and keep
the tip temperature regulated fairly closely.

I still have 2 of them so if you decide to throw them away, send them to
me and I can use them for parts to keep mine in repair. I will reimburse
you for your shipping.

I have more info If you need it.

Thanks for the reply. I will probably keep the soldering station. It seems
to work fine, just no display. Weller made another modle that seemed to be
the same unit without the display. I guess that if Weller did repair them,
they probably just changed out the controller board. Similar to what the
Commador computer people did. They had a flat repair rate. Don;t recall
exectally,but it was something like the board cost them $ 50 and they
charged about $ 70 to repair the computer. All they did was throw away the
old insides and replace them. Seems this way is cheeper than the labor to
repair them.

================================================
On the topic of Weller soldering irons , I would appreciate info on the
following :

At a fleamarket I acquired a Weller soldering iron with a DIL16
de-soldering pad (very handy to remove ICs with up to 16 pins.
However , the heater element (Weller part nr 24410 , 24V-50W) is
defective (open circuit)
By Googling I haven't been successful finding a US supplier for the
heater element.
Can someone on this NG please help with US supplier info ( in the hope
the cost of a replacement element will not make it necessary for me
having to talk to my bank manager).


TIA for any advice

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

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.

They gave it to you because Weller stuff is junk. I have seen more
Weller soldering stations fail then I care to remember over the years.
Don't spend a lot of time on it. Break down and buy a Hexacon station.
We have four here. They have worked flawlessly for over ten years with
heavy use.

No... they gave it to him because it didn't cost much and was defective. At
my current place of employ, we have many Weller EC-series soldering stations
and over the 6 years I've been there, I've seen only a couple of failures.
In 30+ years in radio/electronics, I haven't seen many failures of these
units. I recently bought a new WES50 for myself and am very satisfied.
Tips are widely available and inexpensive.
