  Make sure that the plasma power supply is grounded correctly before doing troubleshooting procedures.
- Frequently used troubleshooting procedures
  - Restart the plasma power supply
  - Troubleshooting for gas pressure problems
  - Keep a clean gas line
    It is extremely important to keep a clean, dry gas line to prevent oil, water, dirt, and other contaminants from causing damage to internal components. A clean gas line also helps you to get optimal cut quality and consumable life.
  - Do a gas test
    Use a gas test to see if sufficient gas pressure is exiting the torch. The gas test lets you see the plasma power supply’s actual gas pressure so that you can compare it to the inlet set pressure.
  - Do a continuity test on the FastConnect torch receptacle
    Use this table to help check continuity between the FastConnect torch receptacle and J19 on the power Printed Circuit Board (PCB). If there is no continuity between any two test points, replace the torch FastConnect™ receptacle.
  - Do an initial resistance check
    The initial resistance check will help determine if there is excessive resistance in the plasma power supply.
