The clamp comprises a balancing module (51) that provides one degree of freedom between the mounting and the mobile subassembly (3, 4, 8) that connects together the fixed (3) and mobile (8) arms and a main actuator (4), and this module (51) has a device (22, 23, 24) for moving this mobile subassembly relative to the mounting in this degree of freedom, for example in translation, the balancing system (52, 58) comprising a flexible device (22, 25, 53) which is connected to the mobile subassembly and which applies a force, in said degree of freedom, to at least one member connected to the mounting, and, in addition, at least one balancing actuator (58) for moving the mobile subassembly to a balanced position relative to the mounting. Particularly applicable to electrical resistance welding clamps. |
