Abstract

The invention relates to a toolholder (10) for coupling a welding torch to an industrial robot (14), comprising a first fixing device (16) for fixing the welding torch (12) to the toolholder (10) and comprising a second fixing device (18) for fixing the toolholder (10) to the industrial robot (14). The first and second fixing devices (16, 18) can be displaced or repositioned with regard to one another counter to the action of spring elements (22, 24). The toolholder also comprises a protective circuit (26) for deactivating the welding torch (12) when predetermined displacements or repositionings are exceeded. A component (28) connected to the first fixing device (16) can be repositioned in the Z-direction (30) (toolholder longitudinal axis) and can be displaced in the X-direction and/or Y-direction (32, 34) with regard to the second fixing device (18). When displacing in the X-direction and/or Y-direction (32, 34), at least one spring element (22) having a first spring hardness is loaded, and at least one second spring element (24) having a second, different spring hardness is loaded during a repositioning in the Z-direction (30). The invention provides that the first spring element(s) (22) and the at least one second spring element (24) are arranged in series or are arranged in succession in two stages.
