PROBLEM TO BE SOLVED: To prevent solder from overflowing out of a jet solder tank. SOLUTION: When an adjustment request D4 is received by a manual jet adjustment button displayed on an operation panel 9, a controller 20 calculates a solder jet amount that is set by rotary encoders 8A and 8B to a solder jet amount that is preliminarily set in the operation panel 9 to output the calculated solder jet amount to motors M1 and M2. Thereby, if the adjustment request D4 by the manual jet adjustment button is not received by the controller 20, and even when the rotary encoders 8A and 8B are wrongly operated in a direction that the rotation number of the motors M1 and M2 is increased to raise the solder jet amount, overflow of the solder from a jet solder tank can be prevented.
