Abstract
An arc welding apparatus comprising a combination of a teaching-playback robot and an arc welding power source is provided. Even when, in changing a welding method, one welding power source for one welding method is replaced by another welding power source for another welding method, the welding apparatus does not require an adjustment between a robot controller and the latter arc welding power source for consistency between them. The arc welding apparatus comprises a teaching-playback robot comprising a robot body and a robot controller and a welding power source including a controller. The robot controller and the controller of the welding power source both have a communication controller, and communicate with each other using a digital signal. On the basis of information on the welding method transmitted from the welding power source, the welding method is automatically set into the robot controller.
