Then, the top of the wire 22 extending from a tube 23 for feeding a welding wire is folded so that the wire 22 is not sucked into the tube 23, and the wire 22 remaining in a welding wire feeder 13 is pulled out. After that, a positioning pin 28 is pulled out, a thumbscrew 30 is loosened, and a swing member 16 is turned clockwise around an axis 17 as a center. As a result, a limit switch 24 is turned off and a limit switch 25 is turned on.</p> |
