Troubleshoot Common Problems
- Start here: troubleshooting checklist
  When a problem occurs, go through the troubleshooting checklist first. It is necessary to complete these steps before doing other troubleshooting procedures.
- Frequently used procedures for troubleshooting
- Troubleshooting for common problems
  - The cut quality is unsatisfactory, or the cut does not sever the workpiece
    Unsatisfactory cut quality can have many causes. These can be related to the cartridge, the work lead connection, the gas supply, or an incorrect output current, cut speed, operating mode, or extension cord.
  - The power switch is ON, but the power LED is off
    The power switch is set to ON (I), but the Power ON Light Emitting Diode (LED) is off. The voltage to the control circuits is not sufficient, or a power component has a short circuit.
  - The arc does not transfer to the workpiece
    The plasma arc does not transfer to the workpiece. The continuity between the work lead and the workpiece is unsatisfactory.
  - The plasma arc stopped while cutting, but starts when you fire the torch again
    There is a problem with the Hypertherm® cartridge, the cut height, the air filter element, or the input gas pressure.
  - The plasma arc makes sputtering and hissing sounds
    There is a problem with the air filter element, or it is necessary to clean the input gas supply. There can also be a problem with the Hypertherm® cartridge.
  - The system changes the gas pressure after you set it manually
    The plasma power supply will override manual gas mode under some conditions.
  - The system changes the output current (A) or the operating mode after you set them
  - Possible gouging problems
    When you are gouging with the torch, you may have an issue. Refer to this table to help identify the problem and solution.

The system changes the gas pressure after you set it manually

The plasma power supply will override manual gas mode under some conditions.

One of these conditions caused the gas pressure to be changed

You installed a different type of Hypertherm® cartridge.
You adjusted the gas pressure before you unlocked the torch.
You enabled "marking mode" by adjusting the amperage to be less than 20 A with a FineCut® Hypertherm cartridge installed on the torch.

Make sure that the torch-lock switch is in the green "ready to fire" position.
Set the amperage to be more than 20 A.
Manually adjust the gas pressure as necessary.

The selected cut mode Light Emitting Diode (LED) on the front panel flashes while the gas pressure is manually set.
