Some info, just like that:
The station does take the 12V WMRP without any problem.
I had lots of troubles with "stuck channels". They where unable to be enabled by the front (pressing up/down shortly). I did manage to enable the channels multiple times by setting them in the Weller software (via the USB connection of course. I cant remember the exact sequence, but is meant locking and unlocking some features. Newer stations don't seem to have this problem.
Mine killed a number of 10A fuses (The SMD fuse on the left of the power PCB) The irons still work fine on other stations though.
Enabling more than 160W on the WD2 makes the station disable one of the two channels.
If your irons heat up until they break, check the Triacs (BT16-600 types if I recall correctly). I fixed this once on a WR3M channel, which basically seems the same like the WD1 and WD2.
I recall a chat with a salesman: The "older" WD1M and WD2M where sold until they where replaced by the WX series. But because of the demand the WD1 and WD2 came back, basically the same stations, but without the default USB interface. Now you can buy the USB PCB seperately (about. 70 euro's if i remember correctly).
I have heard some people about stations that have seem to have lost their firmware. You can reflash it by reading it off another station with an Microchip ICD programmer (confirmed, this works), and flashing it back in the broken station. The Microchip ICD can be soldered to the USB breakout PCB without any problems.
