To provide a solder liquid level control apparatus that can quickly supply solder for a shortage and that has excellent usability.
The solder liquid level control apparatus is equipped with a pair of electrodes 16 connected to a detection circuit, in a freely vertically operated manner. A driving source for the vertical operation is a servo motor 25. An encoder 24 for controllably driving the servo motor 25 is monitored, conduction when the electrodes 16 descend to come in contact with the liquid level of a solder vessel 17 is detected, thus from the value of the encoder 24 when the conduction is detected, the liquid level height of the solder vessel 17 is detected, a difference is obtained between a preset/input liquid level and the detected liquid level height. A controller 20 is provided which supplies an amount of solder 18 corresponding to this difference to the solder vessel 17 by a solder feeding means 26.
