Component replacement schedule
This is a list of components and their recommended replacement schedules. The schedule uses total arc hours to
estimate when to replace a component. The use of cumulative arc hours is the most accurate method to estimate when
you need to replace a component.
If you have a Hypertherm CNC, you can find the total number of arc hours on the CNC. See Find arc hour data on a
Hypertherm CNC on page 25. You can also find cumulative arc hours on a serial communication link between your CNC
and power supply.
If you do not have a Hypertherm CNC and your CNC cannot track arc hours, use the guide below to estimate arc hours
per year. This guide uses the average number of 8-hour shifts that the system operates on an average work day. For more
information about calculating arc hours, contact your table manufacturer.
Your cutting area and operations can have an effect on this schedule. See Cutting area and operation effects on page 21.
Record information about your system and its replacement requirements in the following places:
 Part numbers for HPR800XD Auto Gas cables and leads on page 26
 System information on page 31
 Notes on page 32
