all works fine! the capacitors had some difference in voltage at first start, but controller balanced charges it allowed me to use 10amps for charging with my 12v 20 a power supply, great! it allows max 35ms for 1st and 2nd pulses and 99ms for delay I used 35mm2 copper wire and 32 mosf board, and it works fine and has definitely enough power for using 0.2 mm nickel! it can easily burn through 2 mm nickel plate, and needs 2ms for 1st pulse and 6ms for 2nd interval 20ms to weld 0.2mm nickel to metal plate.
Very fast shipping! Thanks! For Information: controller has english menu.
