Why is the cutting quality weak on my HUAYUAN LGK-63IGBT?

  Tyrone RamosAug 4, 2025
  If the cutting quality of your HUAYUAN Cutter is weak, there are several potential causes: * The gas pressure might be too high or too low, requiring adjustment. * The workpiece might be too thick; ensure it's within the recommended cutting range. * The torch electrode and nozzle could be broken, necessitating replacement. * The plasma arc may not be perpendicular to the workpiece, so adjust the torch angle. * The cutting speed might be too fast or too slow, requiring adjustment.

  If your HUAYUAN Cutter isn't striking an arc but the cutting and gas pressure lamps are on, while the supply abnormity and overheat lamps are off, consider these possibilities: * The cutting ground wire may not be properly connected; ensure it is well connected. * The gas pressure might be too high; lower the gas supply pressure. * The torch electrode and nozzle could be badly broken; replace them. * The torch itself might be damaged; replace the torch.

  If your HUAYUAN Cutter is not striking or is breaking arc during cutting, and the overheat indicator lamp is ON, the following could be the reasons: 1. The ambient temperature may be too high; allow the cutter to rest. 2. The cooling fan might be rotating slowly or not at all, reducing cooling efficiency; check the fan power source or replace the cooling fan. 3. The temperature relay could be damaged; replace it.

  If the supply abnormity indicator lamp is ON without arc striking on your HUAYUAN Cutter, check the three-phase power source. Ensure the supply voltage is in accordance with the supply requirements. The issue may be due to a missing phase, over voltage, or under voltage.
