Default Weller WECP Temtronic bit advice please

I have recently obtained a used Weller WECP Temtronic soldering iron. This unit can be set to a wide range of temperatures by adjusting a pot on the front panel, rather than by changing the bit as in the older TCP range that I have used for more than 50 years. I would like to obtain another, larger chisel bit for the WECP, for heavier work.

The heating element on the iron is identified as an ECP. I am having trouble specifying the bit type as my searches for ECP tips do not come up with bits (tips) that look correct.

I have attached photos of the base unit, label and the iron, bit and holder. I wonder if anyone recognises it and has the correct information to specify the bit type.

Thanks

Ron

The element end of the bit is hollow and a probe from the soldering iron element tube slips inside and possibly senses the temperature.

It looks like my old Weller Thermolock iron tip. Yes the sensor slips just inside the end of the tip.

A quick google shows the 'ET' series bits offered as suitable for the LR 21, FE 50, WEC, thermolock, EC2000 and EC2100 irons, so presumably any of those would fit.

If this is the model I think it is I seem to remember that it takes bits that are virtually identical in size to the TCP bits but without the magnetic slug and a deeper hole for the sensor to fit.

I think these may be the type :- https://uk.farnell.com/w/c/tools-pro...ange=et-series

I have a couple of 4ETP-1 bits bought in error which you could have to prove the point if you like.
