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 IP23S.
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

5/21
ALFA IN a.s ©www.alfain.eu3
one or more of the following:
Antimony
Chromium
Mercury
Nickel
Cobalt
Arsenic
Barium
Copper
Selenium
Beryllium
Lead
Silver
Cadmium
Manganese
Vanadium
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 350V.
30. The maximum open-circuit voltage of the plasma machines is established
by national and international standards (EN 60974-1) depending on the type

6/21
ALFA IN a.s ©www.alfain.eu3
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
Places with increased risk of
electric shock
DC current: 113V

32. In case 1, the dc machines with rectifier must be built in such a way 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:
S
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.

7. GETTING STARTED
7.1 FIRST STEPS
NOTEThis equipment must only be used by qualified personnel.
1. Before beginning work is necessary to connect the machine to the mains.
2. Check completeness of the mounted cutting torch.
3. See the picture below. Connect the torch to the connector. By means of the
thorn (part of the delivery) press the safety pin. Turn the nut of the
connecter clock wise and tight it properly.
4. Connect the compressed air on connector A14 on the rear wall of the
machine.
5. Connect the mains plug to the mains socket.
6. After turning on the ON/OFF switch A15 the display A4 will illuminate.
7. Keep the switch A1 pressed in the position and set the air pressure
by means of regulator A13 and manometer A12 to 6 bars.
8. Connect the work lead cable to the material being cut and to the
connector A11.
9. Check up the input air pressure (min 5 bar, max 8,5 bar) and make a

15/21
ALFA IN a.s ©www.alfain.eu3
regulation if necessary.
10. Set potentiometer A3 to the cutting power you need.
11. Fit the torch with appropriate type of cutting tip electrode and shield
cup according to the selected cutting current.
12. Press the trigger on the cutting torch, the pre gas will flow for 1 s.
13. The pilot arc will start.
14. Shift the torch with the pilot arc close to the material, the pilot arc will
change to cutting arc automatically. If you do not start cutting within 2 s, the
arc will snuff off. When you move the torch away from the material the
cutting arc would change into the pilot arc. In case the cutting process would
not start within 2 s, the arc would extinguish. It is possible to release the
torch trigger in the 4 stoke mode .
15. To finish the cutting the 2 stroke mode release the torch trigger. In
the 4 stroke mode press the torch trigger
7.2 REQUIREMENTS FOR SOURCE OF COMPRESSED AIR
1. Delivered air pressure must be max. 8,5 bar and min. 5 bar.
2. Air consumption minimal 220 l/min
3. Compressed air for the plasma must be clean and dry.
4. Pressure dew point +3 ° C
5. Maximum oil content 0.1 mg/m3
6. Maximal size of solid particles 15 microns
7. The minimal size of an air tank is 50 l
8. No additional oiling if the pressure air is permitted. That could damage
the plasma machine and the cutting torch.
7.3 CONNECTION TO THE CENTRAL AIR DISTRIBUTION
1. Before connection find out the working pressure in the system and range
of its fluctuation.
2. Check out the model and technical state of the filter system and
condensate trap.
3. Make sure the piping is not oiled.
4. Install an additional filter and moisture trap as close to the cutting
machines as possible.
7.4 OPTIONAL AIR FILTERS
To achieve high quality cutting and to avoid serious disturbances to the torch it
is highly advised to include the air filter.

7.5 CUTTING
1. Press the torch trigger. The pilot arc will ignite. Then you have to
immediately attach the torch to the cut material. At this point begins to burn
the main arc between the torch and the material.
2. Move the torch with a constant speed. Cutting speeds vary according to
torch output amperage, the type of material being cut, and operator skill.
3. Output current setting or cutting speeds may be reduced to allow slower
cutting when following a line, or using a template or cutting guide while still
producing cuts of excellent quality
4. To achieve a good cutting quality make sure the distance between the tip
and the material is about 3,5 mm. The Spacer Spring 5391 located at the
end of the plasma torch guarantees the distance (or Spacer for contact
cutting 5396). At a greater distance decreases cutting power and the arc
may go off. With too small distance the torch parts will be worn off faster.
5. Plasma cutting may be done in all possible positions (vertically, horizontally,
overhead, vertical ascending and descending), but as far as possible
choose primarily horizontal cut. In other positions the operator is
increasingly threatened by flying drops of molten material.

17/21
ALFA IN a.s ©www.alfain.eu3
6. We recommend starting cutting at the edge of the material. If needed to
start from the centre of the material, or to cut hole into the material, slightly
tilt the torch head and gradually it straighten into a vertical position so the
spraying material would not damage the cutting tip (see Figure 5). This
workflow must always be followed, if the thickness of material is above
above 3 mm.
7. In case of cutting in the corner or around the corner (see Figure 6), use the
long electrode and cutting tip. The cutting power while using the Long
cutting tip is decreased.
Fig. 5 Fig. 6
7.6 IMPORTANT RULES
1. The pilot arc burning time should be limited only to the time necessary. It
lowers the wear of the cutting tips and electrodes.
2. Never turn off the main switch immediately after finishing cutting but always
leave time to run cooling cycle to cool down the torch. Immediate turn-off
only in case of emergency.
3. The biggest influence on the cut quality, durability of the nozzles, electrodes
and the whole torch has compressed air. Ensure correct setting of pressure:
The pressure during cutting must not fall below 3.5 bar. The air must not
contain mechanical impurities, oil and water condensate. These
contaminants reduce the quality of the cut, causing instability and
extinguishing the arc, and can damage the torch. A source of pressurized
air must therefore be provided with an effective and reliable filtration, oil
separator and water condensate trap. Using filters and separators built on
PEGAS 160 PLASMA as the sole treatment stage air is totally inadequate.
In cases where the compressor sucks air of high humidity, resulting in the
need for frequent draining of the pressure tank, it is necessary to include in
the inlet one more effective as a dirt separator third stage. The captured
condensate must be discharged every day, and all tailing and pressure
vessels compressor. Ensure a good el. contact of the work lead clamps
and cutting material.
4. Check and timely exchange cutting tips and the electrodes. Lifetime of these
parts is only a few hours of cutting time and is highly dependent on
compliance with the principles of good cutting.

18/21
ALFA IN a.s ©www.alfain.eu3
NOTE
5. At low air pressure (below 3,5 bar) LED A8 lights on the control panel and
hang further action.
6. If the machine gets overheated during cutting, the LED on the control panel
A7 lights and hangs other activities of the machine.
7. Disconnect the machine from the mains before replacing the torch
consumable parts.
8. Unplug the machine from the mains before any intervention inside the
machine.
9. PEGAS 160 PLASMA may not be directly connected to the pressure of
higher than 8.5 Mpa or to pressurized cylinders! Connection to such
resources is only possible through a suitable pressure reducing valve, which
is tested on the corresponding input pressure and flow.
10. Imperfect capture of condensate would cause its elimination in the area
of the cutting tip and it would prevent ignition of the pilot arc.
7.7 SOURCES OF POOR QUALITY CUTS
7.7.1 Shallow penetration of the cut
1. The cutting speed is too high. Make sure the slope of the cutting arc does
not exceed about 15 °(see Figure 7).
2. High wear of the cutting tip or electrode (see Figure 8)
3. Too large thickness of material and not adequately chosen value of current
and diameter of the cutting tip.
4. Bad contact between the work lead clamps and material.
7.7.2 Cutting arc is unstable, goes off and "shoots"
1. Worn out cutting tip or electrode
2. High pressure
3. Impurities in the pressure air
4. Not captured water condensate
7.7.3 Conical cut
1. If there is a false cut (see Figure 9) turn off the machine, release the shield
cup and rotate the cutting tip about 1/4 and again try to cut.

8. MAINTENANCE
1. A great care should be taken to the cutting torch. The molten material
sprays while cutting. This sputter contaminates the interior space of the
torch. The worn parts (consumables) of a plasma torch should be regularly
maintained and timely exchanged. Regularly check the condition of diffuser
channels (see diagram of the torch). If contaminated, you must clean it with
a pressure air or to replace the diffuser. Poor state of the diffuser has a
negative impact on the quality of cutting and causes very strong interference
that may cause the collapse of the machine control electronics or influence
the surrounding devices. If the cable bundle of the torch is worn out it must
be replaced immediately - danger of electrical shock.
2. Disconnect the PEGAS from the mains supply voltage before
disassembling.
3. Maintaining the pneumatic system consists of regular draining of the
condensate traps, at least once a day. Furthermore, visually check the level
of pollution of the air filter and if necessary, disassemble and cleaned the
filter.
4. Setting the operating pressure - while cutting the pressure must not fall
below 0.35 MPa. Setpoint is carried out by the control head on the pressure
regulator. Head must first be unlocked by pulling upward, to set the desired
pressure and pushing again downwards to secure. If the machine does not
consume any air, a slight increase in pressure (about 0,05MPa) appears. It
is therefore necessary to check the pressure during cutting.
5. The power generator must be periodically cleaned by compressed air
(according to the degree of dust inside the generator).
NOTE: Beware of the risk of damage to the electronic components by direct
action of compressed air from a small distance.
6. Troubleshooting and repairing of PEGAS equipment should only be carried
out only by suitably qualified or competent person.
7. A ‘competent person’ must be a person who has acquired through training,
qualification or experience, or a combination of them, the knowledge and

skills enabling that person to safely carry out a risk assessment and repairs
to the electrical equipment in question.
8. The person carrying out the servicing needs and repairs must know what to
look at, what to look for and what to do.
