18 ERR SAMPLE ARC
VOLTAGE
With Sample Voltage ON,
the arc voltage samples
from cut to cut were out of
the sample range. This
error can occur if the arc
voltage sample on the next
cut is not within a given
range from the voltage
sample of the previous cut.
For example, if the sample
voltage of the previous cut
was 120 VDC and the
sample voltage of the next
cut is 170 VDC, cutting
stops and the error
displays. The IHS at the
next pierce point could not
be performed accurately.
• The lifter is stalling before
reaching the workpiece.
• Perform an IHS test and verify that the
torch is retracting to the transfer height
accurately.
• The Stall Force is set too high. (Nozzle
Contact is OFF.)
• If the problem continues and cut quality
is affected, disable Sample Voltage
mode and see if the cut quality improves.
• There is slag build-up on the
bottom of the shield.
• Examine the shield for slag build-up.
• The workpiece is not lying flat
on the table.
• Verify that the workpiece is lying flat and
not warping while cutting. If so, set
Nozzle Contact Cutting to OFF in the
Plasma Process screen.
• The consumables were
changed and the consumable
counter in the ArcGlide was not
reset.
• The consumables are damaged.
• The wrong consumables are in
the torch or the plasma system
is using the wrong cutting
process.
• Verify that the consumable life counter
on the ArcGlide was reset after
changing the consumables.
• Examine the consumables for damage,
and verify that the cutting process is
correct.
• There is a problem with plasma
system.
• Verify that the plasma system does not
have any gas leaks or restrictions.
