A few hours ago I started looking at three "smart" light switches that
need LEDs replaced, and switched on the soldering iron, and ... nope.
It's a Weller WP80 and it seems the sensor in the heating element has
died. I discovered that only after resetting and then dismantling the
control unit to check it out with a DVM, of course.
Clearly I need either a new WP80 element, or a new soldering iron. I
could get a WSP80 for far less than the cost of a new element for the
WP80, but I'd get the element faster. So which, if any, is the better
iron? What would you guys do?
I begrudge paying UKP 92 for a new element. That's the cheapest I could
find -- /half/ the most expensive price -- but just seems ludicrously
extortionate for what amounts to a piece of swaged stainless steel tube
with a short length of resistance wire and an even shorter length of
thermocouple wire inside it. I could buy a whole new solder station
with more bells and whistles, albeit of a "lesser brand", for less.

Is the sensor a separate component? On the EC1302 and
several other models, the sensor is
a separate piece that fits up through the center of the
heater and poked into the back of the
replaceable tip. I got one for that iron years ago from, I
think, Newark. So, you might try
at Farnell and see if they have spares.

Sadly, no. That's the first thing I thought of. The heater and sensor
are integral with the stainless steel shaft and I can't see any way to
get them out without destroying the shaft.

for me, the item that usually fails in the WTCP series is the switch at the
end of the sensor.
I have replaced the sensors each time, because dammit - My 40 year old iron
sometimes just needs a new cord, or a new heater, or a new tip, or a new
sensor. Best iron I have ever had :-)

The element in my Weller TCP failed a couple of years ago, after 25
years on my bench and having soldered probably hundreds of thousands
of joints. I bought a replacement (not _too_ expensive) and a spare to
go in the tool cupboard. I then realised that if the replacements last
as long as the original I will never have to buy another element, I'll
be gone first!
