<P>PROBLEM TO BE SOLVED: To provide an arc welding system 21 that causes no malfunction of a shock sensor 22 even when the weight of a welding torch 2 gains to increase a moment working on a welding torch 2. <P>SOLUTION: In the arc welding system 21, a welding robot 1 is controlled by a robot controller 31, and the operation of the welding robot 1 receives teaching from a teach pendant 35 and the welding robot 1 is provided with a welding torch 2 wherein a shock sensor 22 is mounted, at its tip end. The pressurizing force data of a spring 23 in the shock sensor 22 are set by a pressurizing force data setting unit 32 in the teach pendant 35. A driving control circuit 34 in the robot controller 31 outputs a driving control signal S1 by inputting an output signal of the pressurizing force data setting unit 32 of the spring. A driving unit 25 is mounted to the shock sensor 22 to regulate the pressurizing force of the spring 23 when the driving control signal S1 is output. <P>COPYRIGHT: (C)2013,JPO&INPIT |
