Appendix B: Sensor™ THC 185
Purge Time
Specifies the time delay from torch ignition until motion is enabled.
Start Time
Specifies the time delay from when torch completes lowering until motion is initiated at Creep
Speed. Used to allow the Marker to completely transfer to the material before moving.
Sample Voltage
When enabled, the Sample Voltage feature is used to sample the Arc Voltage being recorded
when cutting at a specific cut height, then that Arc Voltage value will be used when cutting the
part instead of a predetermined Arc Voltage.
Set Arc Voltage
The operator may input the desired Arc Voltage for the material being cut.
Mark Height
The Mark Height setup parameter is used to select the desired cut distance from the plate. This
will set the initial cut height before arc voltage control is activated when operating in automatic
mode.
Start Height
The Start Height setup parameter is used to select the desired Start Height. This may be
entered as a multiplication factor that is calculated times the Start Height or an actual Start Height
distance.
Voltage Control
This setup parameter allows the operator to select the Sensor THC to operate in Manual or
Automatic mode. Manual mode will disable the torch height control, allowing 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 setpoint.
Voltage Tracking Range
The Voltage Tracking Range parameter specifies the allowable variation in arc voltage from the
setpoint. If the arc voltage should go above or fall below this allowable range, the system will
fault and pause cutting.
IHS in Manual
The IHS in Manual setup parameter allows the operator to select whether or not to use the Initial
Height Sense feature when operating the Sensor THC in manual mode.
Retract Full/Partial
Selects the retract distance to be set at Full or Partial. In the Full retract mode, the torch will
retract to the Home position. In Partial retract mode, the torch will retract to the set retract
distance.
Partial Retract Distance
This setup parameter is used to select the THC Retract Distance when configured for partial
retract mode.
