A.C. Inverter Control Devices

  • High quality actualizing welding
    Spattering control effect
    Showing power in the plated steel sheet
    Strength electrification of welding current is possible
  • Automation correspondence
    While change of 127 conditions welding, possibility.
    Welding current can be control long way by analog signal
  • Improvement of welding speed
    Can be cooling time control ‘mm/second’ short cycle
  • Decrease of Flicker
    Three phase circuits bala
