The nozzle contact input
was turning on and
off numerous times in
succession or was on
continuously for a period
of time.
The Arc Voltage set point
is set too low.
Sample Arc Voltage is
active and the IHS is
inaccurate.
The travel speed is to low.
The torch height disable
is enabling too early in the
cut or not disabling earlier
enough in corners or in
holes or in some other
sharp radius.
There is slag build-up
between the shield and the
nozzle.
The Ohmic wire shorted
to ground after the cut
started.
The torch is operating in a
water table and the water
is above the surface of the
plate.
The plate is not lying flat on
the plate or is warping due
to heat from the arc.
Check the arc voltage set point and compare the
value to the plasma cut chart.
If sample arc voltage is on, verify the torch height by
doing an IHS test.
Verify that the cut speed equals the cut speed listed
in the cut chart. If the value is red, the speed pot is
over-riding the set point.
Watch the torch height disable while cutting and
verify that this parameter is turning off in corners and
in a radius and verify that it is not turning on while
piercing or immediately after motion starts.
Check the consumables for damage or slag build-up
between the shield and nozzle.
If cutting in a water table, turn Nozzle Contact off
within the plasma process screen.
If the problem occurs while marking, verify that the
torch height, arc voltage, and travel speed are set
according to the marker cut chart.
Check the Ohmic contact wire for damage to the
insulation around the wire.
Verify that the plate is lying flat and not bowing up
while cutting. If so, turn Nozzle Contact During Cut off
in the Plasma Process screen.

The plasma system has
reported an error condition.
The plasma system is
producing an error.
In a discrete system, there
is a loose or damaged
connection to the error
input at the control module
or plasma interface board.
Check the plasma system for an error code.
Verify the error code input wiring to the plasma
interface board.
In a discrete system, check the plasma interface cable
for damage.
Verify that the error output is not continuously on at
the plasma system.
Verify that the error input is functioning on the plasma
interface board and Control Module.
