PURPOSE:To let the angle changing of a torch and weaving operation be effected with one driving source by providing a stop signal command circuit for output revolving shaft of the main unit, a rotating direction command circuit and selection circuit to control circuits. CONSTITUTION:When a weaving command is outputted from input terminal, a command for driving a driving source M3 is emitted from a circuit 41 to a circuit 42 by the signal of a circuit 40 and an R-direction rotation command is emitted from a circuit 39, by which an output revolving shaft 24 is revolved in the R-direction. When the signal is changed over by the outputs of the rotating position detecting means S1 and change amount detecting means S2 of rotating position provided to the revolving shaft 24, then said signal is inputted to a circuit 35 and the opposite signal is emitted from the circuit 39, by which the revolving shaft 24 is revolved in the L direction. When the position of a moving body is controlled by reciprocatively turning the torch by this, the weld line of the work W1 may be automatically welded by weaving. |
