Distance cutting
In some case, it is beneficial cut while
holding the burner sleeve
8c
at a height of
1.5 mm to 3 mm above the workpiece. This
reduces the quantity of material that is blown
back into the tip. This makes it possible to
penetrate thicker material strengths. Distance
cutting should be used if penetration or
furrow work is carried out. Furthermore, the
“distance” working technique can be used
when you need to cut sheet metal to
minimise the risk of material splashing back
which could damage the tip.
Perforation
To drill through place the tip approx.
3.2 mm above the workpiece. Hold the
plasma burner at a slight
8
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 arch 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. If the protective cap is difficult to
tighten, check the thread.
