PURPOSE:To save the unnecessary electric power and to control the scattering of a heating medium by detecting the flow of the heating medium which condenses at the transfer port of the body to be soldered and by automatically controlling the heating power of the heating medium according to the flow quantity of the condensing heat medium thereof. CONSTITUTION:The heating medium 12a condensed by being cooled with a cooling pipe 15 by flowing out to the transfer port 16 of the body to be soldered from a vapor tank 11 is flowed into a U pipe 22 and stored once and falls by flowing out of a notched part 23. The flow quantity of the circulating heat medium 12C flowing out of the notch part 23 from the liquid level height H is operated by operating the liquid level height H on the notch part 23 by an arithmetic circuit part 26 from the pressure measuring value of the pressure gage 24 provided at the inner side of the bottom part of the U pipe 22. The signal concerning the flow quantity thereof is transmitted to a control part 27 from the circuit part 26, an input power source 28 is controlled by the control part 27 and by controlling the heating power of a heater 13 the flow quantity of the circulating heat medium 12C is controlled so as to become to the prescribed value at all times. |
