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.
Auto Kerf Detect
The Auto Kerf Detect feature reduces the possibility of the torch diving into the plate. When
enabled, the THC will detect sudden changes in arc voltage when crossing a kerf path and will
freeze the THC.
