Why does my Panasonic YD-500FD2 Welding System show a temperature rise error?
- A
  audreymillerSep 12, 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.
