Maintenance
- Plasma system maintenance
  Hypertherm® cutting systems can operate in harsh conditions for many years. To maintain cutting system performance, minimize operating costs, and lengthen cutting system life, it is important to follow all maintenance procedures and schedules.
- Daily inspections
  Always do these tasks at least once daily, before system operation.
  - Remove the power from the cutting system
    Many maintenance procedures require you to remove the power from the cutting system. To do this safely, use this procedure.
  - Examine the gas regulators
    Before you start cutting system operation, examine the regulator (or regulators) for the supply gases.
  - Examine the shield water regulator (if applicable)
    If your cutting system uses water as a shield fluid, examine the shield water settings before you start cutting system operation.
  - Examine the connections and fittings
    Inspect all hoses, cables, and leads for any damage or wear, check the fittings that connect these components, and replace any damaged parts. Components should not twist or kink during operation.
  - Remove the torch and consumable parts
    It can be necessary to remove the torch and consumable parts for replacement, maintenance, or troubleshooting.
  - Examine the torch lead
    Inspect the torch lead for any damage, wear, or loose connections, and ensure it meets bend radius requirements; replace or adjust as necessary.
- Indicators of emitter wear
  Emitter wear can be described by the width, depth, and appearance of the electrode pit.
- Measure the pit depth of an electrode
  The pit depth of an electrode refers to the depth of the wear on the hafnium emitter found in the center of the electrode
- Coolant maintenance
  If the Computer Numerical Control (CNC) alerts you that the coolant level is low, remove the power from the cutting system and refill the coolant reservoir immediately.

Examine the gas regulators

Before you start cutting system operation, examine the regulator (or regulators) for the supply gases.

Examine the regulator (or regulators) for the supply gases before you start the cutting operation.
Be sure the supply gas pressures and flow rates are within the recommended range.

Refer to Process-gas requirements for all gas connect consoles.
Adjust the regulator (or regulators) accordingly.
