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 perating 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.
PEGAS 162 E PFC/PEGAS 202 E PFC welds by those methods
a) E – (MMA) coated electrodes up to 4,0 mm
b) TIG lift arc.
PEGAS 162 E PFC/PEGAS 202 E PFC is equipped by system of Power Factor
Correction (PFC) – which enables operating on AC power supply of 95V – 270V.
What are the ad antages of PFC solution?
1. Higher efficiency and less stress related to the circuit breaker (in other
words, circuit breaker will switch off later than the devices without PFC)
2. The machine can be connected to the mains 110 V - 230 V + -15% Small
influence of under voltage and overvoltage mains power
3. Smaller level of electromagnetic interference
4. Minimum net reactive current loading
We reserve the law of adjustments and changes in case of printing errors,
change of technical paramaters, 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. nce 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 ULTRAVI LET RADIATI N 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 F EXPL SI N.

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:
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: pen-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 58V.
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. In high electrical risk areas (in confined spaces) it is only allowed to
use machines with – sign S.
28. Before opening the machine switch off the machine and disconnect
it from the power socket.
29. nly 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.

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.
2. WARNING 
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.
4. CAUTI N 
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 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.
