Whether spot, projection, seam, mesh, butt or flash-butt applications, the Sinius system masters all welding processes. It does not matter whether 50Hz, 1-phase or 3-phase, medium frequency (1kHz) or 10kHz. It meets all the requirements of welding practice. The integrability into an existing PLC via a fieldbus interface are the big advantages of this system. The welding process is visualized on the HMI of the familiar PLC. Focusing on the core area of welding makes the Sinius system both a powerful and a cost-effective investment. Due to the own design of the user interface on the PLC, the retooling of old plants is also one of the strengths of this system.
