In a state where the front end portion of the upper pin protrudes downward, the weld nut inserted onto it is attracted and held by the magnet. In a state where the upper pin is pushed upward by the lower pin, the weld nut comes off the upper pin and drops due to a less attracting force by the magnet, and then fitted onto the lower pin at a position higher than a workpiece. | 12-29-2016 |
