An automatic soldering apparatus is provided to control separately a transfer speed of a printed circuit board in a preheating section and a soldering section by separately controlling first and second conveyors, and to control a transfer speed of the first and second conveyors without lengthening an entire length of the automatic soldering apparatus. An automatic soldering apparatus includes a preheating unit(30) for preheating a printed circuit board(1), a soldering unit(40) for soldering the printed circuit board, and a conveyor for transferring the printed circuit board from a preheating section to a soldering section. The conveyor has a first conveyor(60) installed in the preheating section and a second conveyor(70) installed in the soldering section and controlled independent of the first conveyor.
