- the coil spring 3f is used as the biasing member for generating the biasing force that presses the contact tip 10 inside the chip case 3, but other biasing members may be used, such as rubber. It may be a member, a cylinder, or the like.
- the present invention is suitable for a contact tip replacement device that automatically replaces a contact tip screwed to the tip of a torch body of a welding torch used for arc welding.
