Start IHS Distance
The Start IHS Distance specifies the distance of travel for the THC to move the torch at high
speed before switching to low speed and beginning Initial Height Sense. Caution should be taken
when selecting this distance so that the torch does not crash into the plate.
Skip IHS Within
To increase cutting productivity , the Skip IHS Within feature is used to disable Initial Height
Sense at pierce points if it falls within the selected distance. The distance is measured from the
end point of the cut segment to the next pierce point. If this distance falls within the selected Skip
IHS Within distance, no IHS will take place.
Preflow During IHS
Selecting ON will activate Preflow during the IHS cycle.
Nozzle Contact IHS
This parameter would be set to ON to select the Sensor THC to use Contact Sense to detect the
plate during the IHS cycle. It is recommended that Nozzle Contact Initial Height Sense be used
when cutting light gauge material to prevent plate deflection.
