================================================
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

Hello Frank

Do you have a model number for the iron? If so, what is it?

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.

I cannot say how much I love the WTCP's for being a rugged reliable
workhorse.

I went through two WTCP's. They worked ok, but eventually got
intermittent and would not stay hot. I now have a WES51/PES51 setup.
No more changing tips to change temperature, just dial it in. No led
display, but the dial is calibrated close enough. Also the soldering
pencil is lighter and less bulky than the WTCP was. Still I did like
the WTCP's all in one construction over the two piece (power supply and
iron stand) of the 'ES51. The Coper group has destroyed Weller. I
collect old Weller guns whenever I find them, the new ones SUCK.

Howdy,

I've managed several labs where we had dozens of WTCP stations
in daily use.

The only problem I found with WTCP is the connector between the
base and the cord. I usually remove the connector and hardwire
the cord at the base. It causes the intermittent operation that
you've decribed.

I couldn't agree with you more concerning the damage Cooper
did to the Weller brand. Since they moved production to Mexico
the quality control is nonexistant. Some of the design changes
which I believe were intended as cost reductions were ill advised
too. The old Weller soldering guns are indestructable.

At home I have a Pace soldering/desoldering station and a Metcal
SMT station. I've no complaints other than the price.

At work we have a Hakko soldering/deslodering station and it's a
real work horse. We also have a Metcal SMT station which is a bit
fussy but it has been though hell and back. We just bought a couple
Pace ST70 soldering stations for general purpose work. I think we will
buy a few more, they're great.

It's too bad that Wahl quit selling Sterling soldering irons in
the US. It's an odd little iron but I love it. Thirty years old
and it's still the first iron I reach for in my shop. The original
tip is perfect! I called Wahl about buying a second iron and no one
there knew what I was talking about. The most clever feature is an
aluminum washer between the tip and body of the iron. The difference
in coefficient of expansion keeps the tip from seizing. It says made
in England on the body. Google was no help... sigh.

I have the Weller guns in 3 differant wattage ranges. I think this is one
of each that they made. The 8200 I have is over 40 years old. The middle
wattage gun is one that does not have the hollow nuts that screw into the
end of the rods comming out of the gun. It is labled intermittent duty
where the other 2 do not have this lable. It seems to be lighter than the
smaller rated gun also. I don't use them much any more except to put the
connectors on the PL-259.
I really like the guns for the bigger stuff the pencles will not work. I
even used the 8200 on some of the older and larger PC boards.

I wouldn't be without my TCP, and spares are still available. Cooper
Tools in the UK give excellent customer support (though that's the
people, not the product).

station. I've no complaints other than the price.

soldering stations for general purpose work. I think we will buy a few
more, they're great.

Also take a look at the JBC range of soldering stations. They are beyond
my amateur budget but professional friends rave about them - they seem
to do everything the Metcal range can (and more) without the complex and
expensive RF heating. There's a video presentation at:

If you can post a photograph on a website, someone here in the UK may be
able to identify it.
