Command™ THC 400
Set Arc Current
The Set Arc Current feature 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.
EIA RS-274D part program code G59 Vvalue Fvalue for setting current is supported.
Corner Current Percent
The Corner Current Percent feature allows the operator to select a reduced current setting to be
executed when cutting corners to improve cut quality. This value is a percentage of the Set Current
(above) and is active when the Torch Height Disable Output is on.
Set Arc Voltage
The operator may input the desired Arc Voltage for the material being cut.
Cut Height
The Cut 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.
Retract Distance
This setup parameter is used to select the THC Retract Distance when configured for partial retract
mode.
Pierce Height Factor
The Pierce Height Factor setup parameter is a multiplication factor that is calculated times the Cut
Height to set the pierce height distance.
IHS Stall Current
The Initial Height Sense 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 one (minimum) and ten
(maximum). The limited stall force is always used if nozzle ohmic sense is turned off.
IHS Speed
The Initial Height Sense Speed sets the lifter downward speed during the IHS cycle. This is a relative
factor between one (minimum) and ten (maximum).
Homing Speed
This setup parameter determines the retract or homing speed. This is a relative factor between one
(minimum) and ten (maximum).
Nozzle Ohmic Contact
This parameter would be set to on if the Command
®
THC when using Ohmic Contact Sense to detect
the plate during the IHS cycle.
Preflow During IHS
Selecting ON, will activate preflow during the IHS cycle.
