Hello
My Weller WES51 suddenly failed.
The led doesn't turn on and the tip is not heating
I've checked the power switch the transformer and the voltage of the microcontroller(PIC 12CE673). Everything seems to be ok.
When i tried to check the controller clock and touched with the negative terminal of the oscilloscope in the gnd of the chip the station started to work.
When i remove the negative terminal of the oscilloscope from the gnd of the pin the station stops immediately.
I know that the negative terminal of the oscilloscope is connected to the earth.
The tip of the weller has continuity to the earth terminal.
Any ideas where is the problem?
Tnx!
