After a weld start signal has been inputted, a case where a welding current and a welding voltage, which have been detected by a welding current/voltage detection means, are outside set ranges is made the weld abnormality by an abnormality discrimination means. An abnormality generation time instant and an abnormality termination time instant are calculated with a start signal input timing being made a time axis reference by a time instant calculation means. An abnormality generation position and an abnormality terminus position are operated from data of the time instants and a robot position information by an operation means.
