10. OPTIMISING THE CUTTING

Piercing

Piercing is the most sensitive operation in the plasma cutting technology. It demands very
accurate process control from the robot or CNC-system as well as the operator. The piercing
procedure must programmed in such a manner that no molten material or slag is allowed to
blow back onto the torch. Also upon cut start/end the cutting must be so programmed that the
torch does not touch any slag that may be present at the piercing location.

How to get a better result

To obtain the best possible result the system must be properly installed and adjusted. The
cutting quality is mainly determined by the angle deviation, slag adherence and the cut
surface.

Angle deviation

The angle deviation is either negative or positive. A positive angle deviation arises as a result
of more material being removed at the top of the cut than the bottom. A negative deviation is
a result of the reversed situation. Problems with angle deviation is either that the cut has too
much angle, or that the angle deviation is inconsequent, i.e. positive on one side, negative on
the other.

Too much angle deviation



Wrong distance between torch and work piece. Adjust the distance

Too much distance > positive angle deviation (decrease the arc voltage)
Too little distance > negative angle deviation (increase the arc voltage)

Positive deviation

Straight

Negative deviation



Worn or damaged consumables. Check and exchange.
