Because of the complexity of the process, an inverter technology was used to guarantee high quality of joints. The welding machine is equipped with base-welding tooling, with sensors for correct assembly of parts. In addition, at customer’s request a safety cage for the operator was built and equipped with optical curtains. On the stand a scrap separator was used for the defective welded parts. TECNA welding controller and Siemens PLC control systems were used to control the device.
