Abstract
The invention relates to a method for operating a soldering system for selective wave soldering comprising at least one solder crucible, the solder crucible comprising a solder reservoir, a solder nozzle and a solder pump, the solder pump being designed to guide the liquid solder out from the solder reservoir through the solder nozzle for generating a standing wave from liquid solder. The invention relates, in particular, to a method for cleaning a solder nozzle comprising the following steps: conveying solder from the solder reservoir at a first pump capacity which is adjusted in such a way that a standing wave of liquid solder is generated at a solder level which is below an upper edge of the nozzle outlet of the solder nozzle; introducing a cleaning agent into the nozzle outlet of the solder nozzle; increasing the pumping capacity of the solder pump to a second pump capacity such that the cleaning agent flows over the upper edge of the nozzle such that the cleaning agent is guided to an outer side of the solder nozzle.
