Lead-In, Lead-Out
Enter the appropriate value to ensure proper piercing (Lead-in) and gas bleed-off (Lead-out) to obtain
optimum cut quality.
The location for the lead-in and lead-out is fixed, but can be changed by using the ShapeWizard and
then saving the new shape to disk.
Note: the Rectangle simple shape has the ability to select the
location for the lead-in and lead-out by pressing the SPACE key. Pressing the SPACE key will move
the lead-in and lead-out to the next available location.
Overburn Length
Overburn is used for parts that contain a circular element. Overburn specifies arc length that the
torch will travel past the circle closure point. The dimension entered is the chord length of the
overburn-arc.
In some cases it is desirable to have an underburn length. For these conditions, simply enter a
negative number for the Overburn length.
Part Type
Selects whether you want to cut the part as a separate Piece or a Hole in a larger part. Chain cut
options are available for simple shapes that have external cut paths.
Lead Type
Depending on the shape selected, the style of the Lead in/ Lead out may be selected as Radius, Lock
or Straight line. The Lock style Lead-in creates greater stability for the part and is only available if the
Part Type is set to Piece. Lead-in selection is only available if the Part Type is set to Piece or Hole.
Note: Some shapes will offer drop down fields to increase options with additional parameters.
