  • the input unit 24 of the input/output device P1 on which the welding condition input screen SC1 including the welding conditions before the change and the evaluation results of the welding conditions before the change is displayed receives the input of the new welding conditions based on the operator's operation, and inputs the received new welding conditions to the welding output device PS1A, thereby outputting the welding output based on the input new welding conditions. Therefore, the operator can set new welding conditions while viewing the welding condition input screen SC1 including the welding conditions before change and the evaluation results of the welding conditions before change.
  • the welding condition generation support system 100 includes a welding output device PS1A (an example of a welding machine power supply device) that outputs welding conditions, and an input/output device P1 that can communicate with the welding output device PS1A and can acquire welding evaluation information corresponding to welding conditions and welding condition changing operations (for example, welding condition changing operations based on operator operations).
  • Welding output device PS1A associates welding conditions with welding evaluation information corresponding to the welding conditions and transmits them to input/output device P1.
  • the input/output device P1 displays welding conditions and evaluation information corresponding to the welding conditions, receives change operations for changing the displayed welding conditions, and transmits control commands corresponding to the change operations to the welding output device PS1A.
  • Welding output device PS1A outputs a welding output based on the new welding conditions, which are the changed welding conditions, based on the control command.
  • the welding conditions for the welding conditions for the transformation of the embodiment 1 of the embodiment 1 are based on the input / output device P1 in the input / output device P1 where the welding condition input screen SC1, which includes the welding conditions before the change and the evaluation results of the welding conditions before the change, are based on the worker operation.
  • the welding output based on the new welding condition entered by the welding output device PS1a can be output. Therefore, the operator can set new welding conditions while viewing the welding condition input screen SC1 including the welding conditions before change and the evaluation results of the welding conditions before change.
  • the present disclosure is useful as a welding machine power supply device, a welding condition generation method, and a welding condition generation support system that support setting of welding conditions desired by a worker.
