PURPOSE:To execute solder fusing work at an optimum temp. and to improve the efficiency of parts removing work by arranging a temp. sensor near a spraying port, displaying the temp. and controlling a main heater so that the temp. is set up to the optimum value. CONSTITUTION:Since it is necessary to maintain the temp. of hot air for fusing solder in a solder connection part at the optimum temp. for fusing the solder, the temp. of the hot air is detected by the temp. sensor 13 arranged near the spraying port 11 of a nozzle assembly 10 and the measured temp. is displayed on a temp. display device 11. The main heater 3 is controlled by adjusting a temp. controller 12 so that the display temp. indicates the optimum temperature. Consequently, the hot air on the spraying port is always maintained at the optimum temperature. When it is unnecessary to fuse the solder, a switching shutter 6 is turned off, the hot air is exhausted from an exhaust pipe 5 to the outside, the exhausted hot air is detected by a temp. sensor 4 and the controller 12 is controlled at the regulated exhaust temp. to exhaust the hot air.
