PROBLEM TO BE SOLVED: To solve the problem that the case of adjusting a feeding amount is mixed with the case of adjusting feeding speed, however, it is impossible to switch whether the feeding amount is adjusted or the feeding speed is adjusted in a scene for feeding a welding wire.SOLUTION: A teach pendant TP comprises: a jog dial 13; and an encoder 14 which detects a rotation amount and a rotation direction of the jog dial 13, in which the jog dial 13 is set as manual feeding means of a welding wire 1. A robot controller RC includes two feeding modes to be switched. In a constant speed feeding mode, the welding wire 1 is fed in a direction corresponding to the rotation direction by a predetermined feeding amount for every unit of the rotation amount of the jog dial 13. In a variable speed feeding mode, the feeding speed and a feeding direction are determined based on the rotation amount and the rotation direction of the jog dial 13. The feeding speed is increased or decreased according to speed of rotation. The feeding modes can be simply selected so that control suitable for a scene for feeding the welding wire 1. |
