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.

- 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.

Troubleshooting for common problems

Before you purchase a major replacement component, make sure that you speak about the problem with Hypertherm® Technical Service or the nearest Hypertherm repair facility.

Warning

ELECTRIC SHOCK CAN KILL

Let the system release internal voltages before you touch the capacitors. The capacitors can hold a charge for several minutes after the system is set to OFF.

Warning

INSTANT-ON TORCHES – PLASMA ARC CAN CAUSE INJURY, BURNS

Ignition of the plasma arc occurs immediately when you pull the torch trigger. Before changing the cartridge, one of the following steps is necessary. Whenever possible, complete the first step.

Set the power switch on the plasma power supply to OFF (O).

Move the torch-lock switch to the yellow lock (X) position. Pull the trigger to make sure that the torch does not fire a plasma arc.
