1. INTRODUCTION

Dear Consumers!

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

will be satisfied with our machine.

Welding machine PEGAS 250/320 MIG SYN is IGB invertor. It is designed for

welding method MIG (Metal Inert gas) and MAG (Metal Active Gas). his is

welding in protective atmosphere. We are using inert (impassive) and active

gases during welding. hese methods are very productive and particularly

suitable for the connections of structural steels.

With welding machine PEGAS 250/320 MIG SYN it is possible to weld different

types of connections (blunt, single-sided, double-sided, fillet, lap etc.) using wire

diameter from 0,6 – 0,8 mm, or 1,0 – 1,2 mm of different metals and alloys

(carbon and alloy steels, aluminum alloys etc.).

he machine can be used for welding in areas with increased

danger of electric shock. Machines comply with the relevant requirements for CE

marking.

We reserve the law of adjustments and changes in case of printing errors,

change of technical parameters, accessories etc. without previous notice. hese

changes may not be reflected in the manuals for use in paper or electronic form.

2. SAFETY PRECAUTIONS

PERSONAL PROTECTION

1. For safety reasons, it is necessary to use welding gloves during welding.

hese gloves will protect you before intervention of electric current

(open circuit voltage). It protects you against thermal radiation and splashing

drops of hot metal too. Wear sturdy isolated shoes. Do not wear open shoes,

because drops of hot metal can cause burns.

2. Do not look into the welding arc without eye and face protection. Always use

good quality welding helmet with intact protective filter.

3. he persons appearing in the vicinity of the welding must be informed of the

danger and must be equipped with protective equipment.

4. During welding, especially in small spaces, it is necessary to ensure an

adequate supply of fresh air, because during welding, harmful fumes arise.

5. In tanks of gas, oil, fuel, etc., (even empty ones) do not make welding,

because there is a chance of explosion.

6. In areas with chance of explosion special provisions are applied.

7. Welding machines that are subjected to great exertion must comply with

specific security requirements. hese include the rail pressure of the vessel

etc. hese connections may only be carried out by competently trained

welders with the necessary permissions.

SAFETY REGULATIONS

1. Before starting work with welding machine it is necessary to get familiar with

the provisions of the ČSN 050601 and norm ČSN 050630.

2. With a bottle of CO2 or mixed gases should be handled according to the

regulations for working with pressure vessels contained in ČSN 07 83 05 and

norm ČSN 07 85 09.

3. he welder must use protective equipment.

4. Before working on the electrical part, removing the cover or cleaning it is

necessary to disconnect the device from the network.

3. OPERATING CONDITIONS

1. Putting the machine into operation can be performed only by trained

personnel and only within the technical provisions. he manufacturer is not

liable for damages resulting from improper use or handling. For maintenance

and repair, use only original spare parts from ALFA IN.

2. Device complies with IEC 61000-3-12.

3. he welding machine is tested according to the degree of protection IP 23S,

which provides protection against the intrusion of solid bodies with a diameter

greater than 12 mm and protection against ingress of water, falling on the

machine in a vertical direction or max degree of 60°.

4. he machine must be positioned so that cooling air can enter and leave

through cooling vents with no problem. It is necessary to ensure that there

are no mechanical equipment, especially metal particles (e.g. during grinding)

drawn into the machine.

5. Handling handle is intended for movement, it is not designed to lifting the

machine.

6. In case of overheating of the machine welding is automatically stopped and

this condition is signalized by pilot light.

7. All interventions in the el. equipment as well as repair (removal of the plug,

fuse replacement) should be performed by an authorized person.

8. With competent mains voltage and input must match the plug.

9. Do not use the machine for other purposes, such as defrosting pipes, starter

source, etc.

10. It is necessary for welding machine to undergo a periodic inspection every

6/12 months by an authorized officer according to ČSN 331500 and ČSN

050630– see Maintenance and service tests.

11. he welding machine is designed especially for industrial areas. In case of

using it in other areas there may exist special measures (see EN 60974-10).

12. It is necessary to protect the machine against:

a) Moisture and rain

b) Mechanical damage

c) Draft and possibly ventilation of neighboring machines

d) Excessive overloading – exceeding tech. parameters

e) Rough treatment

f) Chemically aggressive environments

ELECTROMAGNETIC COMPATIBILITY

he 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.

CHOOSING THE FEEDING ROLL

In all machines (ALFA IN MIG / MAG) rolls with two grooves are used. hese

grooves are intended for two different wire diameters (e.g. 0,8 and 1,0 mm).

Rolls for wire feed must comply with the diameter and material of the welding

wire. Only this way a smooth wire feed can be achieved. Irregularities of the wire

feed leads to a poor quality of welding and deformation of the wire.

ADJUSTING THE MACHINE FOR ANOTHER WIRE DIAMETER

In all machines ALFA IN MIG / MAG are used rolls with two grooves. hese

grooves are intended for two different wire diameters (e.g. 0,8 a 1,0 mm). Groove

can be replaced by removing the rolls and rotating them, or use a different roll

grooves with required dimensions.

1. Open the nut E1 to the right, pressure roll E2 will be opened upward
