Hi, someone has a circuit diagram for the Weller VP800 desoldering station, in special in need the pinout for the foot-switch to start the pump. The foot-switch on my station was missing at time of purchase, so i wanted to make my own. I allready have the correct connector (DIN 6pol.) and replacement foot-switch , now i just need the pinout to complete. So in need help from an owner of such a device. Many thanks in advance.
