1. INTRODUCTION
Congratulations on your new ALFA IN product. We are proud to have you as our
customer and will strive to provide you with the best service and reliability in the
industry.
This Operating Manual has been designed to instruct you on the correct use and
operation of your ALFA IN product. Your satisfaction with this product and its
safe operation is our ultimate concern. Therefore please take the time to read
the entire manual, especially the safety precautions. They will help you to avoid
potential hazards that may exist when working with this product.
Read and understand this entire manual and your employer’s safety practices
before installing, operating, or servicing the equipment. While the information
contained in this manual represents the manufacturer's best judgement, the
manufacturer assumes no liability for its use.
Machine HOMER Plasmacut 39 is designed for cutting metal on the basis of
modern technology cutting material through a thin beam plasma gas.
HOMER Plasmacut 39 is designed for high-quality cutting of materials up to 10
mm thick carbon steel (for more information, see instructions below).
At lower demands on the quality of the cut can be cut through (separate) the
material thickness to 15 mm.
We reserve the law of adjustments and changes in case of printing errors,
change of technical parameters, accessories etc. without previous notice. These
changes may not be reflected in the manuals for use in paper or electronic form.

2. SAFETY INSTRUCTIONS AND WARNINGS
1. OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN
BE DANGEROUS AND HAZARDOUS TO YOURHEALTH.
2. Plasma arc cutting produces intense electric and magnetic emissions that
may interfere with the proper function of cardiac pacemakers, hearing aids,
or other electronic health equipment. Persons who work near plasma arc
cutting applications should consult their medical health professional and
the manufacturer of the health equipment to determine whether a hazard
exists.
3. Once the packing has been opened, make sure that the machine is not
damaged. If in any doubt, call the service centre.
4. This equipment must only be used by qualified personnel.
5. During installation, any electric work must only be carried out by trained
personnel.
6. The machine must be used in a dry place with good ventilation.
7. Make sure that no metal dust can be drawn in by the fan inside the
machine, as this could cause damage to the electronic circuits.
8. It is prohibited to connect more than one INVERTER generator in series or
in parallel.
9. When installing the machine, follow the local regulations on safety.
10. The position of the machine must allow easy access by the operator
to the controls and connectors.
11. When the cutting machine is operating, all its covers and doors must
be closed and well fixed.
12. Do not expose the cutting machine to direct sunlight or to heavy rain.
This equipment conforms to protection rating IP21S.
13. The operator must wear gloves, clothes, shoes, and a helmet or a
welder’s helmet, which protect and are fire-resistant in order to protect him
against electric shock, flashes and sparks from cutting.
14. The operator must protect his eyes with safety visor or mask
designed for welding, fitted with standard safety filters. He should also be
aware that during plasma cutting ULTRAVIOLET RADIATION is emitted.
Therefore it is vital that his face is also protected from radiation. Ultraviolet
rays produce the same harmful effect as sun burning on unprotected skin.
15. The operator is obliged to warn anyone near the cutting area of the
risks that cutting involves and to arrange to provide adequate protection
equipment.
16. Keep all fumes and gases from the breathing area.
17. Keep your head out of the fume plume.
18. Use an air-supplied respirator if ventilation is not adequate to remove
all fumes and gases.
19. The kinds of fumes and gases from the plasma arc depend on the
kind of metal being used, coatings on the metal, and the different

processes. You must be very careful when cutting or welding any metals
which may contain one or more of the following:
Nickel
Barium
Beryllium Lead
Cobalt Arsenic
Copper Selenium
Silver
20. Always read the Material Safety Data Sheets (MSDS) that should be
supplied with the material you are using. These MSDSs will give you the
information regarding the kind and amount of fumes and gases that may
be dangerous to your health.
21. It is very important to arrange for sufficient ventilation, especially
when cutting in enclosed spaces. We suggest using suitable fume
extractors to prevent the risk of intoxication by fumes or gas generated by
the cutting process.
22. Noise can cause permanent hearing loss. Plasma arc processes can
cause noise levels to exceed safe limits. You must protect your ears from
loud noise to prevent permanent loss of hearing.
23. To protect your hearing from loud noise, wear protective ear plugs
and/or ear muffs. Protect others in the workplace.
24. Noise levels should be measured to be sure the decibels (sound) do
not exceed safe levels.
25. The operator must ensure all flammable materials are removed from
the work area to avoid any risk of fire.
26. The operator must NEVER cut containers that have previously
contained petrol, lubricants, gas or similar flammable materials, even if the
container has been empty for a considerable time. THERE IS A VERY
HIGH RISK OF EXPLOSION.
27. The operator must be aware of all the special regulations which he
needs to conform to when cutting in enclosed spaces with a high risk of
explosion.
28. To prevent electric shock, we strongly suggest the following rules:
a) Do not work in a damp or humid environment.
b) Do not use the machine if its cables are damaged in any way.
c) Make sure that the earthing system of the electric equipment is correctly
connected and operational.
d) The operator must be insulated from the metal components connected
to the return wire.
e) The earthing of the piece being worked could increase the risk of injury
to the operator.
29. EN 60974-1 Standard: Open-circuit voltage. During the operation of
the machine, the highest voltage, with which it is possible to come into

contact, is the open-circuit voltage between the clamps. In our generator
this voltage is 260V.
30. The maximum open-circuit voltage of the plasma machines is
established by national and international standards (EN 60974-1)
depending on the type of current to be used, on its waveform and on the
hazards arising from the work place. These values are not applicable to
the strike currents and those for stabilisation of the arc that could be above
it.
31. The open-circuit voltage, for as many adjustments as possible, must
never exceed the values relating to the various cases shown in the
following table:
Case Working conditions Open-circuit voltage
1
2
3
4 Plasma cutting
32. In case 1, the dc machines with rectifier must be built in such a way
Places with increased risk of
electric shock
Places without increased risk
of electric shock
Torches held mechanically
with increased protection for
the operator
that, in case of a fault developing in the rectifier (for example open circuit,
short circuit or lack of power), the permitted values cannot be exceeded.
The plasma cutting machines of this type can be marked with the symbol:

33. Before opening the machine switch off the machine and disconnect
it from the power socket.
34. Only personnel authorised by this company can carry out
maintenance on the machine.
