The term “EuroGripper” refers, for example, to a mounting for welding tongs for spot welding, which is frequently used for car body construction. A comprehensive standard was developed for this type of machine. What makes it unique is the combination of different materials that are carefully assembled with one another. Plastic elements provide the electrical insulation and ceramic cylindrical pins ensure a positive, frictional and secure connection. In addition, the thermosetting screw head insulation enables electrical insulation in the area of the screw.
