PROBLEM TO BE SOLVED: To provide a solder jet waveform forming device which forms a stable waveform using an electromagnetic pump, heightens total efficiency equal to that of a pump driven by a motor, and easily and reliably perform cleaning work or the like. SOLUTION: The electromagnetic pump 12 is immersed in solder 5 with a suction port 34 directed to the surface 5a of the solder 5 in a solder tank 1, and the solder 5 is fed to a blowing body 15 to form a jet wave 27 of the solder 5 with a blow port 37 directing above the surface 5a. An internal core 19 of the electromagnetic pump 12 is provided in an advancing/retracing manner from the surface 5a of the solder 5 to easily clean the inside of the electromagnetic pump 12. |
