    Why is there no output from my LOTOS Welding System?
    • T
      Thomas JonesJul 27, 2025
      The absence of output from your LOTOS Welding System may be due to overcurrent protection being activated or a machine failure. Try lowering the input voltage to resolve overcurrent protection issues. If the problem persists, maintenance at a manufacturer or service center is required.

      bradleyscottAug 1, 2025
      A decrease in output current from your LOTOS Welding System can stem from a low input voltage or a thin input line. Try increasing the input voltage. If that doesn't work, thicken the power line.

    Why is high frequency arc not generated on my LOTOS Welding System?
    • M
      margaretreynoldsAug 5, 2025
      If the high frequency arc cannot be generated on your LOTOS Welding System, it could be due to a faulty switch, incorrect airflow selection, or a failing high frequency arc generator. To resolve this, you can: * Replace the switch. * Replace the electrode. * Replace the high frequency arc generator.

    What to do if the warning light is on my LOTOS Welding System?
    • K
      Kathy GalvanAug 11, 2025
      If the warning light is illuminated on your LOTOS Welding System, it indicates either overheating or overcurrent. For overheating, allow the system to cool down before resuming operation. For overcurrent, try lowering the input voltage or consider replacing the machine.

    How to fix a LOTOS Welding System fan that stopped working?
    • U
      urobertsAug 16, 2025
      If the fan on your LOTOS Welding System stops working, there are several potential causes: * The fan power cord might be disconnected. Reconnect the power cord. * The enclosure might be blocking the fan, causing deformations. Reform the enclosure. * The fan itself may have failed. Replace the fan.

    What to do if the current cannot be regulated on my LOTOS Welding System?
    • C
      campbelljonathanAug 21, 2025
      If you're unable to regulate the current on your LOTOS Welding System, it could be due to a disconnected potentiometer line or a faulty current regulation potentiometer. Try reconnecting the line. If that doesn't solve the issue, replace the potentiometer.
