PURPOSE:To eliminate the laboriousness of teaching and to improve the working efficiency of welding by the constitution wherein only the control commands of specific operations except the common operations of welding modes in an arc welding robot are taught to the robot. CONSTITUTION:In the case of MIG welding, if welding conditions for the time T1 until a robot body operates and a crater treating time T2 are inputted by shifting an external selecting switch 32 to an MIG welding position, a current command and a voltage command are outputted to a welding power source 4 from an apparatus control part 23. In the case when WIG welding is required, the timers necessary for welding sequence are T1 and T2 as well as a timer T3 until a wire is fed, and the teaching of the positions and attitude information as well as other welding conditions may be the teaching which is beforehand inputted.Thus all required for the operator is to shift the switch 32 to a TIG welding position and to teach only the T1, T2 and T3. Thereupon a current command and a wire feed command are outputted from the part 23 to the power source 4 according to the welding sequence. |
