Manufacturer: Nippon Avionics Co., Ltd.
Model: NRW-IN400PA

Features of NRW-IN400PA

• Switchable Inverter Frequency
  The model standard operating frequency is 2000Hz (energization time resolution 0.5ms) with the option to switch to 4000Hz (energization time resolution 0.25ms) or 5000Hz (energization time resolution 0.2ms).  The optimal frequency can be selected that realizes high-quality welding with less current ripple based on the workpiece.
• 127-Step Free Style Profile
  The operator has the option to set “SLOPE”, “WELD” and “COOL” arbitrarily with up to 127 steps as a standard feature. Multi-stage slope welding and other multi-stage welding, such as pulse 63-stage welding, are possible.  This feature allows high quality joining by precise heat input control for both resistance weld and resistance heat applications.
• 1 ms Variable Weld Stop Control
  Reduce the margin of error in the workpiece displacement.
• Multi-Transformer Suppor
  The Trans Switch option allows the user to connect up to 4 transformers to one welding controller power supply using a transformer switch.  With this option multiple welding processes can be implemented using a single welding controller and multiple transformers.
• This provides the client with maximum flexibility while maintaining production capacity and capabilities.  In addition, equipment installation costs can be reduced and the load on power equipment in the factory can be reduced (load leveling).
• Simultaneous pressurization, sequential welding and installation of equipment for multiple processes are also possible.In addition, the Transformer Relay Box option allows the user to connect to existing transformer models.
• Welding Parameter Compensation
  To perform optimum welding, the standard programmed weld parameters are fine tune adjusted based on changes in room and electrode temperatures. The “base or typical” welding parameters are stored for each program number.  During the actual weld, parameters are compensated according to changes in room temperature and electrode temperature as monitored by the system.  This allows for more consistent bonds that are not, or at least minimally, affected by changes in the ambient environment.
• Dust-Proof, Reinforced Structure
  Automated systems integration is easier using the model program box which includes remote control.
• Multiple Power Supply Capability
  The model can operate on three-phase power supplied from AC200 to 480V without changing or modifying the standard system welding power supply.
