Switchable inverter frequency. The basic frequency is 2000Hz (energization time resolution 0.5ms). It allows you to switch to 4000Hz (welding time resolution 0.25ms) or 5000Hz (welding time resolution 0.2ms) . Since the frequency can be selected for each program number, a frequency which is optimal to the workpiece can be selected that realizes high-quality welding with less current ripple.

• Equipped with a 127-step freestyle welding profile
  It allows you to set “SLOPE””WELD” and “COOL” arbitrarily within 127 steps as standard. Multi-stage slope welding and multi-stage welding (e.g., pulsation 63-stage welding) are possible, providing a good joining by precise heat input control not only for resistance welding but also for resistance heating applications.
• Variation of weld stop within 1ms
  It reduces the margin of error in the displacement amount of the workpiece.
• Supporting multi-transformers
  The Trans Switch (option) allows you to connect maximum 4 transformers to one welding controller. power supply by using a transformer switcher.
  Multiple welding processes can be realized with a single welding controller and multiple transformers, and while maintaining production capacity, equipment installation costs can be reduced and the capacity of power equipment on the factory side can be reduced (load leveling).
  Simultaneous pressurization, sequential welding, and installation of equipment in two different processes are also possible.
  Also, the Transformer Relay Box (option) allows you to connect to existing old transformer models.
• Welding parameter compensation function
  Welding parameters are registered in advance for each program number.It always realizes to perform optimum welding, by calling out those preset value by an external trigger signal and making fine-tuning those parameter, according to changes in room temperature and electrode temperature.
• Dust-proof reinforced structure
  Improved dust prevention by changing ventilation method. This function reduces malfunctions and failures caused by dust suction in an environment where there is a lot of dust or oil mist.
• Easy installation to automatic machines
  The program box enables you remote control. Facility design becomes easier.
• Multiple power supply support
  It allows you to operate from three-phase AC200 to 480V without changing or modifying the welding power supply.
• Multi-transformer System
  Applicable to be used with maximum 4 trans switchers.
