The powerful compact system QR-CS-2 is optimally suited for medium-sized components up to a weight of 20 kN per station that can be welded with a vertical rotation. The compact system QR-CS-2 has a two-station turning table, whereby the station change is carried out by a vertical rotation. The clamping tools for holding the components can be easily mounted between the faceplates of the positioner. Robot and positioner are mounted on a stable base frame in which all cable connections and other media are protected. The heart of the compact system is the QIROX QRC-410-E robot. The QINEO NexT welding package consists of a welding power source with a maximum of 450 amps welding current, a powerful wire drive and a water-cooled welding torch as well as a mechanical welding torch cleaning. The QR-CS-2 is also equipped with a light barrier as well as a start preselection operating panel to protect operators when changing stations of the dual station positioner.
