Hello all in this nice forum.
I have problem with my ERSA I-Con 1 Welding station. The Station start normal and on the Display ist "No Tool" and the temperature stay "- - -". I dont know what is the problem and I mesure all elements. Have one doppel Diod faulty and I replace it with new. The communication between the wellder element und the MCU is the problem. This doppel diode is from this wiring for communication - i think. Have and other one element with 6 Pins "CVK", aber I can not find it in Internet and I dont know what ist this element. When I start the station this element is hot ~70-80C. I think that this element is DEFEKT. one pin ist connected to MCU Atmega 128 ...
Can someone say me what is this element. I attach a photos.
