This average value is the estimated value of the disturbance where the position of the robot in the prescribed period and the effect of gravity to be exerted on the motor 5 in the position are considered, and the estimated value of the disturbance to be detected in the prescribed period is not much different from this average value unless a work and the welding wire are deposited. However, when the deposition is generated, the difference between the estimated value of the detected disturbance and the average value becomes large. When this difference becomes not less than the preset value, the deposition detecting signal is outputted as the generation of deposition.
