Weller WESD51 Schematics and Other service information
I needed to repair my WESD51 station recently and decided to draw out the schematic to aid in troubleshooting. I also included some oscilloscope captures around the TRIAC and line syncing interrupt input to allow comparisons.
I hope it may be useful to someone in a similar situation. Thermocouple vs ADC input voltages are also listed to correlate temperature to ADC voltages.
