  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.
