ARC welding power supply, peripheral device for ARC welding, and ARC welding apparatus

摘要

In the arc welding power supply and peripheral device for arc welding such as arc welding robot controller, a stored data output unit (19) of an arc welding power supply (10) issues stored data of a welding voltage selector (13) of the arc welding power supply (10) to a stored data input unit (17) of an arc welding robot controller (1), and the stored data input unit (17) of the arc welding robot controller (1) stores the entered stored data in a welding voltage selector (5), so that the memory capacity for stored data of the peripheral device such as arc welding robot controller may be kept to a minimum required limit. Further, for use in various arc welding power supplies, the voltage command type can be easily changed over between the welding voltage command type and adjusting voltage command type.
