Signs that a cartridge is near end-of-life
Usually, the best indication of when to install a new cartridge is when the cut quality is no longer
satisfactory. When it is necessary to replace a cartridge, replace the full cartridge with a new one.
Do not try to disassemble the cartridge.
Figure 5 – Cartridge components
The following signs can be indications that a cartridge is near or at end-of-life:

Examine the nozzle hole. A nozzle hole in good condition is circular. If the nozzle hole is
not circular, replace the cartridge.

Look for a higher rate of 0-30-0 faults. As a cartridge wears, unwanted material can
collect inside the cartridge and cause 0-30-0 faults to occur. Refer to page 130 . In some
conditions, you can remove this material by carefully shaking the cartridge.

Examine the crown . The
crown is the square copper piece
inside of the cartridge. Push
down the crown and then release
the spring tension.
A crown in good condition goes
back to its start position. If the
crown stays in the down position,
carefully shake the cartridge. If
the crown continues to stay in the
down position, replace the
cartridge.

If the system shows an 0-32-0 or 0-32-1 fault code, install a new cartridge. Refer to When
to replace the cartridge (fault code 0-32- n) on page 82.

If you do a lot of piercing, it is possible to see black marks on the retaining
cap. Usually this is not a sign that the cartridge is at end-of-life. Continue
to cut with the cartridge until the cut quality is no longer satisfactory.
