<p>Overflow of solder from a jet solder tank can be prevented. Upon accepting an adjustment request (D4) from a manual jet adjustment button displayed on an operating panel (9), a control unit (20) calculates the solder jet amount set by rotary encoders (8A, 8B) for the solder jet amount preset using the operating panel (9) and outputs the calculated solder jet amount to motors (M1, M2). As a result, if the control unit (20) does not accept the adjustment request (D4) from the manual jet adjustment button, overflow of the solder from the jet solder tank can be prevented even when the rotary encoders (8A, 8B) are operated incorrectly in a direction to increase the solder jet amount to increase the operating speed of the motors (M1, M2).</p> |
