1. INTRODUCTION

Dear consumer,

Company ALFA IN a.s. thanks you for buying our product and believe that you

will be satisfied with our machine.

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.

PEGAS 350 AC/DC PULSE welds by those methods:

. TIG DC (Lift arc or High Frequency ignition)

2. TIG AC (Lift arc or High Frequency ignition)

3. MMA DC coated electrodes up to 4,0 mm

4. MMA AC coated electrodes up to 4,0 mm

Welding machine may be operated only by trained persons and only in the

technical provisions. Company ALFA IN a.s. accept no responsibility for damage

caused by improper use. Before commissioning please read carefully this

manual.

The machine complies with the appropriate CE mark.

For maintenance and repairs, use only original spare parts. There is of course a

complex of our services.

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 PRECAUTIONS

. 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 inventer 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.

0. Do not expose the welding machine to direct sunlight or to heavy rain. This

equipment conforms to protection rating IP23S.

. During welding, the welding cables must be located near or at ground level.

They should be as short as possible.

2. 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.

3. 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.

4. 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.

5. 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.

6. The operator must ensure all flammable materials are removed from the

work area to avoid any risk of fire.

7. 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.

8. 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.

9. To prevent electric shock, we strongly suggest the following rules:

5/20

ALFA IN a.s. © www.alfain.eu

a. Do not work in a damp or humid environment.

b. Do not use the welding 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.

EN 60974- 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.

The maximum open-circuit voltage of the welding machines is established by

national and international standards (EN 60974- ) 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.

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

Places with increased risk of

electric shock

DC current: 3V

peak value

AC current: 68V

peak value and

48V effective

2 Places without increased risk

of electric shock

DC current: 3V

peak value

AC current: 3V

peak value and

80V effective

Torches held mechanically

with increased protection for

the operator

DC current: 4 V

peak value

AC current: 4 V

peak value and

00V effective

In case , 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.

20. Before opening the machine switch off the machine and disconnect it from

the power socket.

2 . Only personnel authorised by this company can carry out maintenance on

the machine.

NOTE:

Device complies with IEC 6 000-3- 2 with following conditions:

Short-circuit power Ssc of network in place at an interface between the user's

supply and the public network (PCC) must be least 358 kW.

User is obliged to consult with the electricity supplier if the impedance of the

network at this point is that required short-circuit capacity Zmax = 45 mΩ and

whether the device can be connected with a public low-voltage network.

On the nameplate are the following symbols: .

ELECTROMAGNETIC COMPATIBILITY

The welding device is in terms of interference designed primarily for industrial

areas. It meets the requirements of EN 60974- 0 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.
