2. SAFETY INSTRUCTIONS AND WARNINGS
1. Once the packing has been opened, make sure that the machine is not
damaged. If in any doubt, call the service centre.
2. This equipment must only be used by qualified personnel.
3. During installation, any electric work must only be carried out by trained
personnel.
4. The machine must be used in a dry place with good ventilation.
5. 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.
6. It is prohibited to connect more than one INVERTER generator in series or in
parallel.
7. When installing the machine, follow the local regulations on safety.
8. The position of the machine must allow easy access by the operator to the
controls and connectors.
9. When the welding machine is operating, all its covers and doors must be
closed and well fixed.
10. Do not expose the welding machine to direct sunlight or to heavy rain. This
equipment conforms to protection rating IP23S.
11. During welding, the welding cables must be located near or at ground level.
They should be as short as possible.
12. 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 welding.
13. 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
electrical welding 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.
14. The operator is obliged to warn anyone near the welding area of the risks
that welding involves and to arrange to provide adequate protection
equipment.
15. It is very important to arrange for sufficient ventilation, especially when
welding in enclosed spaces. We suggest using suitable fume extractors to
prevent the risk of intoxication by fumes or gas generated by the welding
process.
16. The operator must ensure all flammable materials are removed from the
work area to avoid any risk of fire.
17. The operator must NEVER weld 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.
18. The operator must be aware of all the special regulations which he needs
to conform to when welding in enclosed spaces with a high risk of explosion.
19. To prevent electric shock, we strongly suggest the following rules:

5 12
ALFA IN a.s. © www.alfain.eu
20. Do not work in a damp or humid environment.
21. Do not use the welding machine if its cables are damaged in any way.
22. Make sure that the earthing system of the electric equipment is correctly
connected and operational.
23. The operator must be insulated from the metal components connected to
the return wire.
24. The earthing of the piece being worked could increase the risk of injury to
the operator.
25. 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 welding clamps. In our generator this
voltage is 62 V.
26. The maximum open-circuit voltage of the welding machines is established
by national and international standards (EN 60974-1) depending on the type
of weld 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.
27. 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
peak value
AC current: 68V
peak value and
48V effective
2 Places without increased risk
of electric shock
DC current: 113V
peak value
AC current: 113V
peak value and
80V effective
3
Torches held mechanically
with increased protection for
the operator
DC current: 141V
peak value
AC current: 141V
peak value and
100V
effective
28. In case 1, the dc welding 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
welding machines of this type can be marked with the symbol:
S
29. Before opening the machine switch off the machine and disconnect it from
the power socket.
30. Only personnel authorised by this company can carry out maintenance on
the machine.
NOTE:
Device complies with IEC 61000-3-12.

ELECTROMAGNETIC COMPATIBILITY
The welding device is in terms of interference designed primarily for industrial
areas. It meets the requirements of EN 60974-10 class A and it isn’t designed
for using in residential areas, where the electrical energy is supplied by public
low-voltage power supply network. It can be here potential problems with
ensuring of electromagnetic compatibility in this areas, due to interference
caused by power lines as well as the radiated interference. During operation, the
device may be the source of interference.
Caution
We warn users, that they are responsible for possible interference from
welding.

The machine is equipped with a 16 A plug for connection to a single phase
supply 1 x 230 V, the corresponding data for this 16 A plug (Duty Cycle = DC)
are in the table above without brackets.
In order to fully use the technical capabilities of the machine, the machine must
be connected to the industrial single phase networks with a blue plug 32 A with
the maximum permissible fuse of 25 A. The corresponding data for such a 32 A
plug are stated in the table above in brackets.
Another option is to connect the machine to the three-phase mains 3x400 230V
TN-S (CS). The condition is to use a 5 pin 32 A plugs for the supply cable and
connection to the phase voltage. Black (brown) wire connected to one phase
(e.g. L1), the blue wire to the neutral wire (N) and green-yellow wire to the
grounded conductor "PE". In this case, it is possible to connect the machine to
a three-phase socket, which may be protected by fuse max. 25 A.
Attention! Do not connect to the interconnected voltage (delta voltage) (between
2 phases)!
Replacement of the plug may only be performed by ALFA IN authorized service
personnel.

7. ROUTINE MAINTENANCE & INSPECTION
1. The only routine maintenance required for the PEGAS range of machines is
a thorough cleaning and inspection, with the frequency depending on the
usage and the operating environment.
 WARNING 
2. Disconnect the PEGAS from the mains supply voltage before disassembling.
3. Special maintenance is not necessary for the control unit parts in the Welder.
If these parts are damaged for any reason, replacement is recommended.
CAUTION 
4. Do not blow air into the welder during cleaning. Blowing air into the welder
can cause metal particles to interfere with sensitive electronic components
and cause damage to the welder.
5. To clean the welder, disconnect it from the mains supply voltage then open
the enclosure and use a vacuum cleaner to remove any accumulated dirt and

11 12
ALFA IN a.s. © www.alfain.eu
dust. The welder should also be wiped clean. If necessary, solvents that are
recommended for cleaning electrical apparatus may be used.
6. Troubleshooting and repairing of PEGAS welding 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.
