Standard behavior with short circuit

In the event of a short circuit, the electrode is stopped and retracted
along the infeed vector.
Once the short circuit is eliminated, the TNC moves the electrode back
along the infeed vector toward the workpiece but stops a certain
distance before the point where the short circuit occurred (this
distance is defined in parameter MP2050).

The machine tool builder may have specified a different
retraction behavior in the event of short circuiting than is
described here.
Refer to your machine tool manual.
