MAINTENANCE
Error Description Possible Causes Corrective action
9
This error occurs if the
nozzle contact input
remains active after making
plate contact and while the
torch is retracting after an
IHS.
The Ohmic contact wire
could be damaged.
The nozzle and shield
could be shorted together
or the wrong consumable
combination was installed
in the torch.
There could be a problem
with the lifter mechanics.
Water from a water table
is causing a short between
the shield and the nozzle.
The coolant conductivity in
a HPRXD plasma system
is too high.
The plate might be
bowing during an IHS
and following the torch up
while retracting.
Check the condition of the Ohmic contact wire and
replace it if necessary.
Check the torch tip for an electrical short between the
shield and nozzle.
Check the consumables for damage and for the
correct combination.
Disable Nozzle Contact in the Plasma process screen
if a water table is used or water injection plasma
system is used.
Verify that the lifter is not binding mechanically and
that it can retract.
Check nozzle contact input within the diagnostic
screen of EDGEPro, or at HMI or control module.
If input is always active, disconnect the Ohmic wire
from the lifter PCB and verify that the input shuts
off. If the input stays on, check the condition of the
lifter cable. The lifter cable could be faulty or there
could be a faulty input to the control module. Call
Hypertherm Technical Service for further assistance.
If the input shut off, disconnect the Ohmic wire from
the back of the torch and reconnect it to the lifter
PCB. If the input remains on, the Ohmic contact wire
is faulty. If the input shuts off, the problem is due to
either the consumables or the torch coolant. Call
Hypertherm Technical Service.
