• 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 (13) for wear and tear,
cracks or exposed cable pieces. Replace or repair
them prior to using the device. A badly worn sleeve
(16) contributes to the reduction of speed, voltage
and unclean separation.
An indication of a badly worn sleeve (16) is an ex-
tended or oversized nozzle opening. The external
electrode (18) must not be recessed by more than
3.2 mm. Replace it if it is more worn than the spec-
ified dimension.
• If the protective cap is difficult to tighten, check the
thread.
10. Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions.
The customer's mains connection as well as the ex-
tension cable used must also comply with these reg-
ulations.
Damaged electrical connection cable
The insulation on electrical connection cables is of-
ten damaged.
This may have the following causes:
• Passage points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been improp-
erly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Make sure that the connection cable does
not hang on the power network during the inspection.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables with the same marking.
32 | GB
The printing of the type designation on the connection
cable is mandatory.
11. Cleaning
• Switch off the main power supply and the main
switch of the device prior to carrying out mainte-
nance or repair work on the plasma cutter.
• Regularly clean the outside of the plasma cutter and
its accessories. Use compressed air, cotton waste
or a brush to remove dirt and dust.
• In case of a defect or a necessary replacement of
equipment parts, please contact the appropriate
qualified personnel.
12. Transport
Switch off the device before transporting it.
Lift the plasma cutter using the carrying handle (1).
13. Storage
Store the device and its accessories in a dark, dry and
frost-proof place that is inaccessible to children. The
optimum storage temperature is between 5 and 30˚C.
Cover the electrical tool in order to protect it from
dust and moisture. Store the operating manual with
the electrical tool.
14. Maintenance
m ATTENTION!
Pull out the power plug before carrying out any mainte-
nance work on the equipment.
• The parts displayed in Figure 7 are the electrode
(18), the diffuser (17) and the nozzle (16). They can
be replaced once the ceramic cap (15) has been un-
screwed.
• The electrode (18) must be replaced if there is a cra-
ter of approximately 1.5 mm depth in the centre.
• The nozzle (16) must be placed if the central bore
is damaged or if it has expanded in comparison to a
drilling of a new nozzle. If the electrode (18) or the
nozzle (16) are replaced too late, this can result in
an overheating of the parts. This can reduce the lift
cycle of the diffuser (17).
