Upper Electrode with insulator for Nut Welding
About Nut Detect Tip
Nut detect tip prevents upside down nut and miss feed of nut to be welded by separating between electrode section and SS ring by insulator. When reversed nut is fed or no nut is fed, no current condition will be made which makes nut not be welded on work. It is also that temporary stop or re-start of related devices and Robot can be carried out very quick if "No current function" on Spot welder's timer is used.
