High-reliability inverter-type Welder
NRW-IN400PA

Best choice for magnet wire fusing and copper alloy battery tab welding

This is a highly reliable inverter-type resistance welding power supply that enables high-definition control and installation in an automatic machine. It is equipped with a mode (Free Style Profile) that can optionally set "SLOPE""WELD" and "COOL" within up to 127 steps, enabling precise heat input control required for better bonding of the fusing. In addition, by reducing internal loss and by development of high-efficiency, high-voltage transformer, high current values can be output in a short time, enabling welding of copper alloy battery tabs.

Features

• 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
