    Why does my Panasonic YD-350FD2 show a temperature rise error?
    • J
      Jennifer HolderAug 19, 2025
      If you get a temperature rise error on your Panasonic Welding System, it could be due to a rise in temperature inside the welding power source, over duty cycle or airflow blockage at ventilation and cooling fan windows. Do NOT turn OFF the machine before the temperature in the Product decreases. Keep the input power in no load state and wait for a while. Check and remove causes of over-heat. If the problem persists, clean the cooling fan.

    What to do if Panasonic YD-350FD2 shows secondary over-current error?
    • H
      Haley MillerAug 21, 2025
      If you are getting a secondary over-current error on your Panasonic Welding System, it is likely due to a short-circuit in the secondary circuit. Turn the welding gun switch OFF and remove the cause of the over current.

    What causes a primary over-voltage error on a Panasonic YD-350FD2?
    • G
      gandersonAug 23, 2025
      If your Panasonic Welding System displays a primary over-voltage error, it means the input voltage is too high (exceeds AC 437V). After input voltage returns within the allowable range, then turn power switch back ON again.

    Why am I getting a primary under-voltage error on my Panasonic Welding System?
    • D
      Dalton PrattAug 26, 2025
      A primary under-voltage error on your Panasonic Welding System indicates that the input voltage is too low (lower than AC 304V) or there is a phase failure in the input power source. After input voltage returns within the allowable range, then turn power switch back ON again.

    How to troubleshoot Arc Start error on Panasonic YD-350FD2 Welding System?
    • D
      Dean MartinezSep 1, 2025
      An Arc Start error on your Panasonic Welding System means that neither an arc is generated nor no-load voltage is detected when the torch switch is turned on. Switch off power source switch, remove the cause of the arc ignition error.

    What does current detection error mean on Panasonic Welding System?
    • S
      Stephanie GonzalezSep 3, 2025
      A current detection error on your Panasonic Welding System means output current or voltage is detected when the power switch is turned on. Turn the power switch OFF and then check the followings to remove the cause(s). This product is defective. Check if the current or voltage is applied to the secondary side of this product from an external device.
