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 320 and 400 AC DC PULSE weld by those methods:

1. TIG (PULSE) DC (Lift arc or High Frequency ignition)

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

3. MMA DC coated electrodes

4. MMA AC coated electrodes

PEGAS 320 and 400 AC DC PULSE have these special functions for effective

use: Pre gas and Post gas of protective gas, Up slope and Down slope, Starting

current and Final current, HF ignition, 2T and 4T mode, Aluminum cleaning level,

Pulsed mode, AC balance and Up-down control from the torch.

For MMA method are these machines equipped with functions Hot Start, Arc

Force and Antistick.

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

PERSONAL PROTECTION

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

These 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. The 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. These include the rail pressure of the

vessel etc. These connections may only be carried out by competently

trained welders with the necessary permissions.

SAFETY REGUALTIONS

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.

3. The 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 CONTROLS

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

personnel and only within the technical provisions. The 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. The 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. The 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. 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.

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

fuse replacement) should be performed by an authorized person.

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

8. It is necessary to protect the machine against:

a. Moisture and rain

b. Chemically aggressive environments

c. Mechanical damage

d. Draft and possibly ventilation of neighboring machines

e. Excessive overloading – exceeding tech. parameters

f. Rough treatment

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.
