1.INTRODUCTION

Dear Consumer, ALFA IN a.s. thank you for purchasing our product, and

we hope you will be satisfied with our machine.

The welding machine may only be operated by trained persons within the

technical provisions. ALFA IN a.s. will not accept liability for damage

caused by improper use. Please read these operating instructions

carefully before putting the machine into operation.

The machines meet the requirements corresponding to the CE mark.

Use only original spare parts for maintenance and repairs. Our service

department is, of course, at your disposal.

If the machine is marked with the following mark

on the nameplate

or the control panel, it can be used for welding in areas with an increased

risk of electric shock.

The ALFIN 300 AC/DC is an inverter welding current generator that welds

in the following methods:

TIG AC

TIG DC

MMA

We reserve the right to make modifications and changes in case of printing

errors, changes in technical parameters, accessories, etc., without prior

notice. These changes may not be reflected in the instructions for use in

paper or electronic form.

2. WORK SAFETY

PERSONAL PROTECTION

1. For safety reasons, protective gloves must be worn when welding.

These gloves protect you from electric shock (circuit voltage when idle).

They also protect you from heat radiation and splashing hot metal

droplets.

2. Wear sturdy, insulated footwear. Open shoes are not suitable as hot

metal droplets can cause burns.

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

wear a good-quality welding hood with the protective filter intact.

4. Persons near the welding area must also be informed of the danger and

provided with protective equipment.

5. A sufficient supply of fresh air must be ensured when welding,

especially in small spaces, as welding produces harmful fumes.

6. Do not conduct welding near gas, oil, fuel, etc. tanks (even empty

ones), as there is a risk of explosion.

7. Special regulations apply in areas with explosion hazards.

8. Welded joints that are subjected to high stress must meet special safety

requirements. This applies in particular to rails, pressure vessels, etc.

These joints may only be made by qualified welders with the necessary

authorization.

9. Notice

Persons with implanted pacemakers must not work with the machines

or move close to them! There is a risk of impairing the function of the

pacemaker!

10. Stop welding immediately if the main cable is damaged. Do not touch

this cable. Pull it out of the socket.

SAFETY REGULATIONS

1. Before beginning any welding work, it is essential to become familiar

with the welding machine and the safety regulations for metal welding

and arc welding that are currently in effect in your country.

2. The CO2 bottle of mixed gases must be handled following the

regulations for working with pressure vessels.

3. The welder must use protective equipment.

4. When handling the machine using the lifting device, hang the machine

on all the suspension eyes (not standard equipment, not possible on

all ALFA IN machines). Other attachment methods are not permitted.

5. Before any intervention in the electrical part, removal of the cover or

cleaning, the device must be disconnected from the mains.

3.OPERATING CONDITIONS

1. Commissioning of the instrument may only be carried out by trained

personnel and only within the technical provisions. The manufacturer is

not liable for damage caused by improper use and operation. Only use

original ALFA IN spare parts for maintenance and repair.

2. The equipment complies with IEC 61000-3-12.

3. The welding machine is tested according to the IP23S degree of

protection standard, which protects against solid bodies with a diameter

greater than 12 mm and protection against water ingress falling in a

vertical to oblique direction up to a slope of 60°.

4. Operating ambient temperature between -10 and +40 °C.

5. Relative humidity below 90% at +20 °C.

6. Up to 3000 m altitude.

7. The machine must be positioned so cooling air can enter and exit

unhindered through the air slots. No electronic components are located

in the cooling duct area, but care must be taken to ensure no metallic

waste is drawn into the machine (e.g. during machining).

8. It is essential to conduct a regular inspection on the welding machine

every 6 to 12 months, as per the regulations for the revision of electrical

equipment in your country and the rules for welding and safety

provisions for metal arc welding. It is recommended that an authorized

employee perform the inspection.

9. All interventions in the electrical equipment and repairs (removal of the

mains plug, replacement of fuses) may only be carried out by an

authorized person.

10. The relevant mains voltage and power supply must correspond to

the mains plug.

NoticeIf the machine has been moved from an area with a low

temperature to a significantly warmer environment, condensation may

occur, especially inside the welder. This will reduce the electrical strength

and increase the risk of electrical flashover on voltage-stressed parts,

seriously damaging the machine. If this situation occurs, leaving the

welder at rest for about 1 hour is necessary until the temperature has

equilibrated with the environment. This will stop any condensation. Only

after this time has elapsed can the welder be connected to the mains and

started.

11. The machine must be protected from:

a. Moisture and rain - it must not be operated in the rain!

b. Mechanical damage

c. Draughts and possible ventilation of adjacent machines

6/41

ALFA IN a.s. © www.alfain.eu

d. Excessive overloading – exceeding technical parameters

e. Rough handling

12. The handling handle on machines with wheeled chassis is designed

for travelling only and not for lifting the machine.

13. Use only the designated transport equipment to transport the welder.

Do not use a forklift or single crate to move.

14. The stability of the machine is guaranteed up to an inclination of 10°

if the following conditions are met:

a. The machine must be secured against spontaneous movement,

b. The feed unit must not be mounted on the generator,

c. A gas cylinder with a maximum height of 0.9 m may be placed

on the platform and properly anchored.

15. The extension cables must not have conductors with cross-sections

smaller than 3x2.5 mm2 for single-phase machines. The machine may

be operated on a single-phase power generator of 6 kVA

(1x230V/50Hz) or more, with a voltage stabilization of ± 10%.

Generators with lower power can damage the machine.

NoticeDue to the installed capacity's size, the distribution

companies' approval may be required to connect the equipment to the

public distribution network.

ELECTROMAGNETIC COMPATIBILITY

Welding equipment is primarily designed for industrial environments in

terms of EMI. It complies with EN 60974-10 class A requirements and is

not intended for use in residential areas where the public low-voltage

supply network supplies electricity. There may be potential problems with

ensuring electromagnetic compatibility in these areas caused by line-

propagated and radiated interference.

During operation, the equipment may be a source of interference.

NoticeThe user is advised that he is responsible for any interference

from welding.
