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.
- 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.

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

Use an electrode pit-depth gauge to measure the pit depth on the electrode.

A pit-depth gauge is available from Hypertherm®. Refer to Other consumable and torch parts.

This image shows how to measure pit depth.

Note:

The electrode shown is not to scale.
