    After I assembled the board with beeper, capacitor and the cables it was not working. There was no power at the welding tips. When checking the boards circuit I found this: MCU output -> drives a PNP transistor -> drives the gates of the N-ch FETs. I post a photo of the schematic: It cannot work. The diode is assembled in wrong direction (the PNP transistor will never switch on) and even if it is reversed it cannot work. The PNP transisitor is always on then because the voltage after the diode

    No bad tool, i am glad by work of li-solder. Отличный аппарат, провода правда коротковатые и оч толстые, в целом за свою цену это отличный девайс для сварки акб.
