ArcGlide THC Instruction Manual 2-61
INStALLAtIoN
Stall force*
Description: This value determines the amount of force used for the Stall Force backup to the normal Ohmic plate
sensing.
When to use: During installation and possibly when cutting thin material.
How to use:
The values are relative values and start at 1 for the minimum force and 10 for the maximum force. This
value should be set high enough to avoid false stall detection but not so high that the excess force
causes a deflection of the workpiece and inaccurate IHS operation.
With the Hypertherm 24.13-cm (9.5-inch) lifter, the value of 5 is appropriate. It may be necessary to
reduce this value if the THC is used with a thin workpiece. Use the Test IHS function to optimize this
value.
Test this feature by disabling the Ohmic contact either by using the process menu or by removing the
Ohmic contact wire. The Stall Force value is optimum when there are no false workpiece detections
and the IHS operation is relatively accurate.
Range: 1 to 10, the default setting = 5
Voltage Calibration*
Description: This value is used to finely calibrate the measured arc voltage accuracy.
When to use: This parameter is not normally required. It can be used for fine tuning in multiple ArcGlide installations
or for long leads.
How to use: The measured input value is multiplied by the value of this parameter before being used for either
voltage control or display. To determine this value, measure the raw arc voltage. If the arc voltage in
the display is different, divide the raw arc voltage by the value in the display and enter the result as the
value for this parameter. For example, if the raw arc voltage is 120 and the value in the display is 125,
divide 120 by 125, the result, 0.96 would be the value for the Voltage Calibration parameter.
This calibration affects all of the ArcGlide hardware connected to this station including the HMI
display and the HPR Hypernet interface. When an ArcGlide is shipped from the factory, the voltage
has been calibrated in hardware and this value is set to (1.000). This parameter is normally only used
to adjust for the exact same arc voltage displays on multiple ArcGlide installations.
Range: 0.900 to 1.100, the default setting = 1.000
Arc Voltage Display
Description: This Arc Voltage value is for display only and cannot be edited. It is provided to check the results after
you change the Arc Voltage Calibration above.
When to use: During arc voltage calibration
How to use:
This parameter is used for display only.
Range: 0 to 400
