Abstract
A single teaching apparatus may be provided for all welding control apparatus in a welding control apparatus in order to input the welding sequence data. The internal address of a welding control apparatus 22 and the welding sequence data are output to a field bus from an upper control apparatus 2. Programming is accomplished by storing the welding sequence data output from the upper control apparatus 2 in a designated address of memory unit 28. Programming of the welding control apparatus 22 can be accomplished: using the teaching apparatus 4 provided for the upper control apparatus 2.
Claims19
