PURPOSE:To execute easily and surely soldering without excess or shortage by melting solder in a vessel having a nozzle, exerting force to the molten solder from the outside and extruding the solder from the nozzle. CONSTITUTION:A heater 2 is provided around a solder melting tank 7 having a nozzle 14. The heater 2 is insulated from other parts by insulators 3, 4 and is protected by a heater cover 5. The insertion of the solder into the tank 7 is executed by opening a screw part 6. Pressure is exerted through a pressure conduit part 8 to the solder 1 melted by the heater 2 and the solder is injected from the nozzle 14 when a piston 11 is pushed. A ball 10 for a check valve is pushed to close an air passage 16 when the piston 11 is pushed. The ball 10 returns to open the passage 16 and the introduce air from the outside when the piston 11 is returned by a spring 15. |
