  If your HUAYUAN Cutter shows no arc striking and neither the supply abnormity nor the overheat lamp is illuminated, several factors could be at play. First, ensure the cutting ground wire is properly connected. Second, verify that the gas pressure is not excessively high and lower it if necessary. Also, inspect the torch electrode and nozzle for damage, replacing them if they are broken. Finally, the torch itself might be damaged, requiring replacement.

  If you're experiencing weak cutting quality with your HUAYUAN Cutter, several factors could be responsible. Begin by checking the gas pressure, ensuring it's neither too high nor too low, and adjust it accordingly. Confirm that the workpiece thickness is within the recommended cutting range. Inspect the torch electrode and nozzle for any damage, replacing them if necessary. Ensure the plasma arc is perpendicular to the workpiece, adjusting the torch angle if needed. Finally, fine-tune the cutting speed, as it might be either too fast or too slow.

  If your HUAYUAN Cutter isn't striking or is breaking arc during cutting, and the overheat indicator is lit, the following could be the cause: The ambient temperature may be too high, in which case you should let the cutter rest. Check whether the cooling fan rotates slowly or not at all, and verify its power source or replace the fan if needed. Also, the temperature relay might be damaged, requiring replacement.

  If the supply abnormity indicator lamp is ON but there is no arc striking on your HUAYUAN Cutter, it could be due to a three-phase power issue. Check the three-phase power source to ensure the supply voltage is in accordance with the supply requirements. It may be experiencing either missing phase, over voltage, or under voltage.
