PURPOSE:To provide the titled device reducing the burden for equipment by operating with the selective output of the memory one unit of more than three units of welders, by operating the following welder with the selection of the priority memory at the same time with the completion and by operating reasonably numerous welders with one unit of the equipment. CONSTITUTION:The memory signal (electrifying preparation signal) of the welder to be operated is inputted into each memory circuits 2-5 via a detecting circuit 1. With motioning one of the memory circuits 2-5 according to the order of precedence of a selective circuit 7 the welder thereof is activated by a data output circuit 9. The following welder is activated with resetting (10) the completion of the welding and operating the memory circuit of the next order. The duplication and jump activation are eliminated with activating each one unit of the welder according to the priority order afterwards. With efficient and reasonable operation of each welder by having comparatively small electric capacity the burden for equipment is reduced. |
