Perforation
To drill through place the tip approx. 3 mm above the workpiece. Hold the plasma burner
8
at a slight
angle to guide the sparks away from the burner sleeve
8c
and your body. Press the plasma burner
button
8a
and lower the tip of the plasma burner until there is a main cutting arc and sparks begin to
form. Test the perforation on a test object that is no longer needed and once there are no problems start
drilling through at the previously defined cutting line on your workpiece. Check the plasma burner
8
for wear and tear, cracks or exposed cable pieces. Replace or repair them prior to using the device.
A badly worn burner sleeve
8c
contributes to the reduction of speed, voltage and unclean separation.
An indication of a badly worn burner sleeve
8c
is an extended or oversized nozzle opening. The
external electrode
8d
must not be recessed by more than 3.2 mm. Replace it if it is more worn than the
specified dimension.
