ARC WELDING POWER SOURCE, PERIPHERAL EQUIPMENT FOR ARC WELDING, AND ARC WELDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a peripheral equipment for arc welding such as an arc welding power source or a robot controller and an arc welding device which suppress a storage capacity with respect to a unified voltage value to the absolute minimum.;SOLUTION: In this peripheral equipment such as the arc welding power supply, or the robot controller, the unified voltage value of a unified voltage arithmetic part 13 of the arc welding power source 10 is outputted to a unified voltage input part 17 of the robot controller 1, by a unified voltage output part 19 of the arc welding power source 10, and an inputted unified voltage value is stored in a unified voltage arithmetic part 5 by a unified voltage input part 17 of the robot controller 1, so that the storage capacity with respect to the unified voltage value of the peripheral equipment such as the robot controller can be suppressed to the absolute minimum. Further, a voltage command system can easily be switched between an individual voltage command system and a unified voltage command system to various arc welding power supplies.;COPYRIGHT: (C)2000,JPO
