3 – Operation
THC mode
Height Control: In Manual mode, the torch only moves in response to manual UP/DOWN commands from the Raise
and Lower soft keys in Phoenix software, an operator console, the HMI, or the lifter. No other torch height
motion occurs. In Automatic mode, the torch moves through its programmed sequence, based on values set
on the Process screen.
Setting: Manual/Automatic
Voltage Control: The THC must be in Automatic mode. If Voltage Control is ON, the torch height is controlled by the
measured arc voltage. If Voltage Control is OFF, the torch maintains a constant position during the cut that is
independent of the arc voltage.
Setting: Off/On
Sample Voltage: The THC must be in Automatic mode and Voltage Control must be ON. When Sample Voltage is ON,
the THC measures the voltage at the end of the AVC Delay and uses it as a setpoint for the remainder of the
cut. When Sample Voltage is OFF, Set Arc Voltage is used as the setpoint for torch height control.
Setting: Off/On
Cut chart values
These fields display the values in the cut chart that is active for the process. These values can be changed here, for this
job, and the values for the automatically-set parameters will be recalculated and displayed. However, these changes are
not saved in the cut chart.
Set Arc Voltage: The ArcGlide THC must be in Automatic mode, Voltage Control must be ON, and Sample Voltage
must be OFF.
When Sample Voltage is OFF, Set Arc Voltage is used as the setpoint for torch height control.
Setting: 50 VDC to 300 VDC
Set Arc Current: This is the value for the plasma arc current. Enter the amperage needed to cut the material. This
parameter can be used only with plasma systems that communicate with the CNC.
Setting: 5 A to 1000 A
Cut Height: Determines the height at which the torch cuts the workpiece.
Setting: 0.25 mm to 25.4 mm (0.01 inch to 1.00 inch)
Pierce Height: Determines the height at which the torch pierces the workpiece. The torch moves to this height after
Transfer Height.
Setting: 0.25 mm to 25.40 mm (0.01 inch to 1.00 inch)
Pierce Time: This is the value for the Pierce Delay. During this time, the X/Y cutting motion is delayed to allow the
plasma to fully pierce the workpiece.
Setting: 0 seconds to 10 seconds
