MF-RWC-3500

- Medium frequency inverter control with IGBT, with the possibility of choosing the inverter operating frequency between 1000 Hz and 10000 HZ. 

- Management of 250 welding programs, each program is identifiable and searchable by means of an alphanumeric identifier of 32 characters. 

- Graphical display of the trend of electrical (current, energy, power, voltage, etc.) and mechanical (electrode displace-ment) quantities during the welding process. 

- Possibility of modifying the currently running welding program without interrupting the operation of the control; the changes made will be used in the next weld point. 

- Web interface for control programming and analysis of diagnostics and welding data. 

- Interface for connection to a PLC integrated within the control, possibility to choose Profinet, EtherCAT, Ethernet IP, Modbus TCP as communication bus. 

- Pre-weld, slope-up, weld 2 and 3, pulse, slope-down and post-weld functions; weld time adjustment with resolution of 1mS or with resolution up to 100uS in micro-welding mode. 

- Six different operating modes: constant conduction time, constant current, constant power, constant voltage, constant energy, adaptive mode able to actively compensate the welding parameters to obtain a constant welding quality. 

- Double management of welding data limits; it is possible to set a first WARNING window in which a pre-alarm signal is generated and a second BAD window in which the wrong point signal is generated. Limits on current, voltage, po-wer, energy, resistance, IGBT onduction percentage, material thickness, force, pressure and temperature are defi-nable. 

- IIntegrated management for one proportional valve. 

- USB interface for backup / restore operations, firmware update and log saving of performed points. 

- Management of 4 different welding transformers, even with different working frequencies. 

- Management of up to 4 position sensors for measuring the thickness of the material at the beginning and end of wel-ding and for interrupting the welding process when the required indentation value is reached. 

- Incremental function to compensate for the wear of the electrodes with programmable curves, possibility of indepen-dent intervention on time, current and welding force, through differentiated increment laws. Possibility of using 4 different incremental laws associated with 4 different point counters and freely associable with each welding program. 

- Integration of the incremental function with the management of the electrodes campaign; possibility to manage up to a maximum of 4 diferent electrode campaigns at the same time thanks to the 4 different points counters avai-lable. 

- Double stroke function. 

- Graphic LCD with encoder for initial configuration operations and for local control of the control diagnostics. 

- 1 auxiliary analog inputs allow you to manage a setpoint for the external welding current. 

- Management of 3 solenoid valves 24 Vdc 5 W Max with auto protected output. Protection against the activation of a solenoid valve in the event of a short circuit of a control cable with a power cable.
