PURPOSE:To facilitate the connection of input and output apparatus and to shorten a teaching time by so constituting a titled controller that the conditions for controlling the operation starting of programs and the numbers of the input and output apparatus can be taught. CONSTITUTION:When the position information and welding conditions of respective programs P1-P4 are taught, the numbers of the external input and output apparatus in an apparatus control part 54 for operation of the respective programs are taught from keyboard switches 36. More specifically, the program P1 is started when the number 12 of the external input and output apparatus is on and the P2, P3, P4 are started when the numbers 8, 4, 16 of said apparatus are on. In this state, automatic welding is executed cooperatively with an external jig 34, and if the cooperative operation of the P3, P4 with the jig 34 is poor, the numbers 4, 16 are held intact and an another external jig is connected in an other vacant place. If a desired state is obtained, the teaching for the cooperative operation with the jig 34 by the sequence among the programs is completed. |
