Transfer Time
Specifies the amount of time to attempt ignition of the torch. The ignition is confirmed
by the Arc Sense Input (Arc on Feedback) to the control.
Set Arc Current
Allows the user to set the arc current at the plasma supply. This feature uses the “Set
Current BCD” output from the control to activate the BCD inputs at the plasma supply
and supports EIA RS-274D part program code G59 Vvalue Fvalue for setting current.
Corner Current Percent
Allows the operator to improve cut quality at corners by selecting a reduced current
setting for cutting corners. This value is a percentage of the Set Current (above) and is
active when the Torch Height Disable Output is on.
Set Arc Voltage
Selects the desired Arc Voltage for the material being cut.
Cut Height
Selects the desired cut distance from the plate and sets the initial cut height before Arc
Voltage control is activated.
Retract Distance
Selects the THC Retract Distance when partial retract mode is configured.
Pierce Height Factor
Is a factor that is multiplied by the Cut Height value to set the pierce height distance.
IHS Stall Current
Sets the lifter downward force to detect when the torch makes contact with the plate
during the IHS cycle. This is a relative factor between 1 and 10. The limited stall force
is always used if nozzle ohmic sense is turned off.
IHS Speed
Sets the lifter downward speed during the IHS cycle. This is a relative factor between 1
and 10.
Homing Speed
Determines the retract or homing speed. This is a relative factor between 1 and 10.
Nozzle Ohmic Contact
Select ON for the Command THC when using Ohmic Contact Sense to detect the plate
during the IHS cycle.
Preflow During IHS
Select ON to activate preflow during the IHS cycle.
