WARNING: none of the machines described in this
manual is equipped with a lifting device.
WARNING !
SAFETY OF PLASMA CUTTING SYSTEM.
- Only the type of torch and its relative connection to
the power source indicated in
DATA" ensure the efficacy of the safety measures
adopted by the manufacturer (interblocking system).
- DO NOT USE torches and relative consumables
different from original ones.
- DO NOT TRY TO FIT torches for cutting or welding
procedures to this power source, if they are not
described in these instructions.
- IF THESE RULES ARE NOT OBSERVED serious
dangers may occur both to the user and to the
machine.

3. INSTALLATION
ASSEMBLING OF SEPARATE PARTS:
Unpack the Plasma 40HF and assemble the different
parts: see picture of the compressed air connection.
COMPRESSED AIR CONNECTION
Arrange a compressed air distribution line having the
following minimum features:
Air pressure 4.5 bars; capacity 170 L/min.
WARNING !
Air with considerable quantities of humidity or oil
may cause an excessive wear of the parts or even
damage the torch.
If there are any doubts about the quality of
compressed air available, we advise to use an air dryer,
to be installed above the entry filter.
Connect, by means of a flexible piping, the compressed
Class I
air line to the machine, using one of the connectors
IP 23
included to be set on the entry air filter, which is on the
H
rear of the machine.

WARNING !
Do not exceed maximum entry pressure of 8 bars.

MAINS CONNECTION
5.2
- The machine may be connected to a line-neuter
system by means of a "PE" protection earth
20
connector. Check that the plug terminal is connected
to the distribution ground .
- Connect the mains cable terminals to a normalized
370
plug (1PH + PE) of the same capacity.

CONNECTION TO GROUND CABLE
Connect the work cable clamp to the piece to be cut or
to the metallic workbench.Take following precautions:
- VERIFY THAT THERE IS A GOOD ELECTRIC
CONTACT PARTICULARLY IF
OXIDATED COATED SHEETS ARE CUT.
- MAKE GROUND CONNECTION AS CLOSE AS
POSSIBLE TO CUTTING AREA.
- THE USE OF METALLIC STRUCTURES WHICH
ARE NOT PART OF THE WORKPIECE, SUCH AS
THE RETURN CABLE OF THE CUTTING
CURRENT, MAY ENDANGER THE SAFETY
SYSTEM AND GIVE POOR CUTTING RESULT S.
- DO NOT MAKE A GROUND CONNECTION ON
THE PIECE WHICH HAS TO BE REMOVED.
CONNECTION OF PLASMA CUTTING TORCH.
Torch insert male connector of the torch into
centralized connector on the front panel of the
machine, take care that polarization key matches.
Screw the ring nut tightly clockwise to ensure air flow
without leaks.
WARNING !
Before starting with cutting operations verify that the
parts are properly assembled by inspecting the head
of the torch as shown on paragraph "TORCH
MAINTENANCE".
