I threw out all of my Weller irons, all a bunch of crap.

I've had two WCC100's in my shop since they came out, probably more than
ten years now. I've never had any problems with them, running them each
10-20 hours/week, doing stuff from tiny surface mount to some jewelry
soldering to the occasional connector pin with #12 wire. I don't expect
them to last forever but I do take care of them and don't leave them on
longer than I need to.

Commercial outfits I've worked for have had similar experiences with the
more expensive Weller irons, usually running them 40+ hours/week. I've
seen them last for years this way, and yes, I've seen a few fail but the
former well overshadows the latter.

Wellers are probably no better or worse overall than anything else.

The Weller WCC103 temperature sensor is actually an iron-constantan
thermocouple (possibly Type J), although Weller used Type K thermocouples
for its EC station series .
Sensitivity believed to be about 50 µV/°C
The relationship between temperature and voltage produced is NON-Linear.

What is a thermocouple sensor?
A thermocouple is a sensor for measuring temperature. It consists of two
dissimilar metals, joined together at one end. When the junction of the
two metals is heated or cooled a voltage is produced that can be
correlated back to the temperature. The thermocouple alloys are commonly
available as wire.

When replacing the WCC103 sensor the leads MUST be correctly installed or
the iron stays on continuously and eventually overheats.
The Iron (magnetic) lead connects to the RED wire
The Constantan (copper-nickel alloy/non-magnetic) lead connects to the
YELLOW wire

This is an informational post for owners of the Weller WCC100 soldering
station.
Some Elecraft builders have used this soldering station for building
their kits.

This is the BLUE colored station that was sold by Weller until 1999, when
it was discontinued

The Weller WLC100, which is an ORANGE colored station, is a totally
DIFFERENT station.
The WLC100 is NOT temeprature controller uses an OEM light dimemr module)
and uses the Weller "ST" series of soldering tips. Information on the
WLC100 model, can be found he
