The robot control apparatus is provided with: program display means (6) for displaying the work program in a list form; child program list producing means (3) for retrieving another work program which is called by the work program so as to form a child program list; mother program list producing means (4) for retrieving another work program which calls the work program so as to form a mother program list; related program storage means (5) for storing both the child program list and the mother program list in the storage means; and display selecting means (7) for selecting a display way in the case that the work program is displayed in the lit form.

Abstract: Arc generation time is obtained for each region to be welded by measuring the time during which the arc current (or voltage) exceeds a reference current (or voltage) and is compared with predetermined time which is set depending on the welding operation. An abnormality is detected in welding if the arc generation time is shorter.
