High Productivity by High Speed Welding!

This model is the highly efficient welding power supply that adopted an inverter. It responds to the change during welding at real time by fast feedback. The highly stabilized welding current generated by the power supply is optimal to the resistance welding for precision electronic parts.

  • Multi control mode (constant-current, voltage, power)
  • Pre-weld check function
  • Long-time welding (maximum 3sec)
  • 400V Standard (NRW-IN8400)
  • Graphic display of welding waveform on large LCD
  • Multi monitoring function
  • Welding waveform-memory function
