AN EXAMPLE OF CUTTING A LEAD-IN WHEN CUTTING HOLE IN AN OBJECT
When cutting an object, particularly a pattern shape, where the torch must pierce or re-fire in-line
at an intersection of a cut, a lead-in cut should be employed. A lead-in is a cut that is made in the
disposable part (also known as a drop) of the object to "lead" into the main part of the cut so that
the destructive force of the arc is not directed into the desirable side of the cut itself. Also, all plasma
cutters exhibit some angularity or bevel in the cut which is greater on one side than the other. Keep
this in mind when cutting an object to size so that too much metal is not accidentally removed.
