Hello. The lack of a diagram often discourages repairing the device. I drew a diagram of the Powolin welding machine from Powermax2. The diagram is in such a shape as the elements on the motherboard are placed. It's nice to print it on A2 format, due to the high density of elements. The colors of the lines correspond to the potential according to the legend. I've provided all the values and names of elements, and basic voltages. When you notice errors, please pay attention to this, I will apply the corrections.
