Plasma Distance To Corner
The Plasma Distance to Corner parameter specifies the distance to the corner at which the plasma
system should switch from low current to high current or disable the Automated Height Sensor.
Distance to Corner is active whenever the speed drops below the Plasma Hi/Lo Percentage, or
segments intersect at an angle greater than the tangent angle.
Plasma Distance From Corner
The Plasma Distance from Corner parameter specifies the distance from the corner when exiting, at
which the plasma system should enable the Automated Height Sensor. Distance from Corner is
active whenever the speed drops below the Plasma Hi/Lo Percentage, or segments intersect at an
angle greater than the tangent angle.
Example:
For the example illustrated below, the Torch Height Disable output will be activated based on the
values of the setup parameters.
Plasma Hi/Lo Percentage Value 90%
Distance to Corner Value
.5 inches
Distance from Corner Value .5 inches
Tangent Angle Value 20 Degrees
For the above listed values, the Torch Height Disable output is active .5 inches before and .5 inches
after each 90 degree corner. The THD output is also activated as the torch accelerates away from
the pierce and through the arc due to the speed being below the Plasma Hi/Lo value. Finally,
because the arc intersects at greater than the 20 degree tangent angle, the THD output is activated
for .5 inches before and after the beginning of the arc, and is activated for .5 inches before and after
the end of the arc.
