Sample Voltage
If this parameter is enabled, it samples the Arc Voltage that is recorded when cutting at a
specified cut height. The value of this sample arc voltage is used to cut the part instead
of a predetermined arc voltage.
Set Arc Voltage
Records the arc voltage for the material being cut.
Mark Height
Sets the cut distance from the plate. This value sets the initial cut height before arc
voltage control is activated when operating in automatic mode.
Start Height
Sets the start height for the cut. This can be entered as a percentage of the start height or
as an actual start height distance.
Voltage Control
Allows the operator to select the Sensor THC to operate in manual or automatic mode.
Manual mode disables the torch height control and allows the torch to cut at the specified
cut height and voltage. Automatic mode allows the THC to command the torch up and
down to maintain the voltage at the specified arc voltage set point.
Voltage Tracking Range
Sets the allowable variation in arc voltage from the set point. If the arc voltage exceeds
this range, the system faults and pauses cutting.
IHS in Manual
Allows the operator to select whether to use the initial height sense when the Sensor THC
is in manual mode.
Retract Full/Partial
Selects the retract distance. If Full is selected, the torch retracts to the home position. If
Partial is selected, the torch retracts to the distance set in the Partial Retract Distance
field.
Partial Retract Distance
Sets the distance that the THC retracts when partial retract is selected.
Start IHS Distance
Specifies the distance that the THC moves the torch at high speed before switching to
low speed and beginning initial height sense. Take care to select a distance that allows
the torch to clear the plate.
