<p>An automatic restoration method is offered in which the cause of a failure of arcing is automatically removed to resume the starting operation so that an arc-welding robot system may be automated more efficiently. If no arcing occurs, the torch of a welding machine is moved by the robot body (S1 to S4). When an arc is formed before the torch moves by a predetermined distance, the torch is restored to the arc start position (S5 to S7) and the welding is started.</p> |
