PURPOSE:To improve the follow-up property by calculating the minimum welding current value detection time or the maximum arc voltage detection time, from a weaving center position, and comparing this time with a detection time at the time of real welding. CONSTITUTION:A weaving condition setting part 14 sets a weaving frequency and a weaving width. In accordance with a condition which is inputted from the weaving condition setting part 14, a reference time arithmetic part 15 calculates the minimum current value detection time at the time when there is no aim shift of a torch position. A control part 16 derives the minimum current detection time from a data of a welding current storage part 13, compares it with the time which is outputted from the reference time arithmetic parts 15, and executes a correction of the torch position. |
