DragSPATZH1600/H2400 High Frequency Inverter Power Source


Within the SPATZ-family the DragSPATZ power sources are the most powerful 20 kHz Inverters. The areas of application are projection welding and the welding of materials which possess good electrical conductivity, e.g. aluminum or copper.

The 20 kHz inverter technology shows numerous advantages: The residual ripple of the welding current is negligible. The setting precision for the welding parameters is very high - current times can be programmed in 0.1 ms increments. The short current rise times enable extremely short welding operations of only several milliseconds. The control cycle time of 25 s ensures uniform and reproducible quality in the welded joint, even at these short welding times.

The MASDAT-interface permits further progression for a flexible, effective and cost efficient production and maintenance respectively by connecting an intelligent welding gun identification system. The proportional valve output and 63 different schedules also come as standard.

All 10,000 weld data records of the weld data recorder which is integrated in every DragSPATZH1600/H2400 can be read and stored with the operating units. Each data record is comprised of the weld values like current, voltage, energy, resistance, penetration and force. Further a time/date tag and information about the crossed limits and fault status are stored. For fast I/O communication via robot controller or line PLC a PROFIBUS-DP interface is available. Alternatively, 13 digital inputs and 8 outputs ensure a reliable data exchange via standard protocols.

The DragSPATZH1600/H2400 is able to work without an operating device. Programming the DragSPATZH1600/H2400 and analyzing of the weld process occurs via the handy graphical operating device SPATZBG-02, a local PC with the AutoSPATZAS-01 PC software via RS-232 or a line PC with the AutoSPATZAS-32 software via an Ethernet connection.
