PURPOSE:To enable optimum welding and to improve working efficiency and quality of welding, by enabling the operator to recognize the welding current value and voltage value during execution of weldings with good accuracy according to need. CONSTITUTION:A switch 12 for commanding the output of welding conditions for outputting the actual current value and actual voltage value during welding by voice is provided at the vicinity of a torch switch 12. A control circuit 17 takes therein the signal CS from an input circuit 13, and respectively feedback signals AFB and VFB from a feedback circuit 14 for welding conditions, calculates the value of the average welding current and average welding voltage and controls the output after converting said values to prescribed voice levels. A condition storage circuit 18 is constituted of a storage section CMRY for conditions value for storing the actual welding current value and actual welding voltage value converted and regulated to prescribed digital quantity with the circuit 17 at optional sampling time and a storage section AMRY for average conditions value for storing the average values in accordance with the data of the CMRY. A voice synthesizing circuit 19 produces the output signal for welding conditions by voice from a speaker 20. |
