The AutoSPATZM1600/M2400 1,000 Hz medium frequency inverter power
source is used in combination with external medium frequency transformers as a high-performance,
cost-effective DC power supply within a welding current range of 5 kA to 60 kA. It is
especially designed for the demands of mass production with a high number of parts - e.g.
automotive body shops.
Each welding operation is feedback controlled during the procedure. The control process takes place very quickly based on the 1 kHz inverter frequency. Actual values are compared with the set values every 0.5 ms. The output power is modified during the welding process if targets are not being met. The adaptive MASTER control process is frequently used. Constant Current Control (CCC), Constant Power Control (CPC) and Constant Voltage Control (CVC) are also provided.
At the end of each weld, the AutoSPATZM1600/M2400 checks whether the actual welding parameters keep within the set limits.
The online programming, analysis and diagnostics are the key links between production, quality control and process engineering. Three options are available. The handy graphical operating device SPATZBG-02 meets the demand to be used under rough production conditions. Maintenance technicians can derive further detailed information with a notebook connected to the AutoSPATZ RS-232 interface and the AutoSPATZAS-01 PC software. An Ethernet interface in combination with the Line-PC Software AutoSPATZAS-32 enables the networking of all welding operations with a line PC.
Through the graphic representation of the curve characteristics of the process signals welding current, electrode voltage, welding power, electrode force and electrode penetration the weld expert recieves all information which he needs for adjusting the welding parameters. The recorded values of the welds and the graphic representation of the measured value trends are a useful tool for guaranteeing the weld spot quality for operators and maintenance technicians.
All 10,000 weld data records of the weld data recorder which is integrated in every AutoSPATZM1600/M2400 can be read and stored with the operating units. Each data record is comprised of the weld values, a time/date tag and information about the crossed limits and fault status.
An offline analysis of the weld data records with the SPATZQS quality assurance software or a standard program - e.g. spreadsheet program - illustrates the quality control the present process status and process development.
For fast I/O communication with a higher level device - e.g. robot controller or line PLC - a PROFIBUS-DP interface is available. Alternatively, 13 additional digital inputs and 8 outputs ensure a reliable data exchange utilizing standard protocol with 24 V DC signals.
With every docking of the welding gun which is equipped with MASDAT, the AutoSPATZM1600/M2400 is automatically programmed with all weld parameters - e.g. MASTER reference curves - of the welding gun. Additionally, manufacturers' data and maintenance data are transferred to the AutoSPATZ. On the other hand the AutoSPATZ actualizes this data in the gun. The direct storage of data in the weld gun reduces the scope of organizational work relating to maintenance documentation, the updating of welding parameters and backup welding data.
