1.INTRODUCTION

Dear consumer,

ALFA IN a.s. Thank you for purchasing our product and we believe that you will

be satisfied with our machine.

The SVAROG 85 PLASMA CNC machine is designed for cutting metals on the

basis of modern technology of material cutting by means of a thin jet of plasma

gas. This technology has several advantages over other methods

1. High cutting speed

2. Quality cut with a minimum area of the changed material structure

3. Smaller thermal deformations of the cut material

4. Possibility of cutting carbon and high-alloy, stainless steels and non-

ferrous metals

5. The method does not require any special gases

6. Lower costs

SVAROG 85 PLASMA CNC is equipped with a proportional valve that allows

precise automatic and synergic settings of the required working pressure of the

cutting gas (according to the cutting mode and the cutting current). As well the

manual settings of the cutting gas pressure can be adjusted right from the control

panel.

The machine is equipped with the ecological function "fan on demand". If cooling

is not required, the machine automatically shuts off the fan.

The CNC models support the cutting arc remote control of the CNC table

controllers.

SVAROG 85 PLASMA CNC is designed for high-quality cutting of materials up

to 30 mm thick mild steel. Productive cutting of carbon steel can be to a

thickness of 20 mm. At lower demands on the quality of the cut can be cut

through (separate) the material thickness to 35 mm. Maximal piercing is 25 mm

(mild steel). For more data see TECHNICAL DATA.

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

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

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

2.SAFETY

General requirements

1. The machine may only be operated by a worker who is thoroughly familiar

with the issue of plasma cutting and who has received appropriatetraining.

2. Disconnect the device from the mains before any work on the electrical

part, removal of the cover or cleaning.

3. For the cutting machine, it is necessary to perform a periodic inspection

once every 6/12 months by an authorized employee –see paragraph

Maintenance.

4. For safety reasons, protective gloves must be worn when plasma cutting

These gloves protect you from heat radiation and splashes of hot metal.

5. Wear solid insulated shoes. Open shoes are not suitable as drops of hot

metal can cause burns.

6. Do not look into the cutting arc without face and eye protection. Always

use a high-quality welding helmet with an intact protective filter.

7. Persons in the vicinity of the cutting site must also be informed of the

danger and must be provided with protective equipment.

8. When cutting, especially in small spaces, a sufficient supply of fresh air

must be ensured, as harmful fumes are produced during cutting.

9. Do not perform cutting work on gas, oil, fuel, etc. tanks (even empty ones)

as there is a risk of explosion.

10. Special regulations apply in potentially explosive atmospheres.

Protective equipment

1. Welding helmet with filter shade at least 10

Note

The machine torch cannot be used for versions without CNC!

Note

1. It is forbidden to operate a machine with damaged insulation of the

cutting torch or supply cable.

2. Never operate the machine taken down or damaged covers.

3. In addition to the risk of injury, the cooling efficiency decreases and the

level of interference increases.

4. It is forbidden to operate the machine in wet environments and outdoors

in rain or snow.

5. Ensure proper grounding clamping pliers, which also reduces the risk of

electric shock.

6. Use prescribed protective utilities, keep them dry.

7. Plasma arc cutting produces intense electric and magnetic emissions

that may interfere with the proper function of cardiac pacemakers,

hearing aids, or other electronic health equipment. Persons who work

near plasma arc cutting applications should consult their medical health

professional and the manufacturer of the health equipment to determine

whether a hazard exists.

8. The cutting and pilot arc is a source of very intense light and especially

ultraviolet radiation. This radiation can significantly damage the eyesight

in a veryshort time and,with prolonged exposure, causes redness to burns

of uncovered parts of the skin.

9. Use a welding helmet equipped with an intact filter with a degree of

protection of min. 10.

10. The risk of burns arises when cutting from flying hot metal particles,

plasma arc and hot cut material. A thin beam of red-hot plasma (4th state

of matter) reaches up to 10,000 ° C in its core!

11. Never point the torch at the eyes, body or other person during

ignition.

12. Always wear good quality and undamaged welding gloves, apron

and welding clothing, including closed shoes and headgear.

13. During cutting, a large amount of gaseous emissions and dust

particles is formed from the material being cut.

14. High temperatures lead to chemical reactions and the formation of

various oxides andothercompounds, some of which are harmfulto health.

15. Particularly hazardous fumes are produced when cutting material

containing lead, beryllium, cadmium (cadmium-plated parts) and painted

materials.

16. Ultraviolet radiation and high temperatures also produce significant

amounts of ozone and nitrogen oxides.

6/32

ALFA IN a.s ©www.alfain.eu

17. Exceeding the concentration of these gases above the values given

by hygienic standards can cause damage to health, especially with

prolonged exposure.

18. Workplaces must be well ventilated and equipped with an effective

extraction system.

19. In addition, a breathing mask must be used when cutting material

where particularly hazardous fumes are generated.

20. During its operation, the machine produces noise, the level of which

reaches the value of 80-85 dB.

21. We recommend using hearing protection for longer work.

Pressure air source requirements

The supply air pressure must not exceed 8.5 bar and must not be less than 6.5

bar. The operating pressure and air consumption for the prescribed torch are

given in chapter Chyba! Nenalezen zdroj odkazů..

For reliable operation of the plasma cutter and quality cuts, we recommend the

following recommendations when selecting the appropriate type of compressor:

1. The compressor must be able to deliver a minimum of 295/370 litres/min

of compressed air permanently. This parameter is referred to in the

catalogues as the so-called "compressed air capacity“.

NoticeNot to be confused with „suctioned quantity"!

2. The aerator must be equipped with a drain valve.

3. It is essentialthat the compressor is equippedwith acompressed air cooler

or a sufficiently large air receiver. Otherwise, heated air enters the

distribution system and may contain significant amounts of water that

cannot be captured in the separators. As the air cools after it passes

through the ducts, it may reach the dew point, causing water droplets to

be expelled, which may be after the separator. The optimum size of the

airbox is at least 100 litres.

4. An efficient filter with sufficient capacity, an oil and condensate separator

or a pressure regulator must be installed at the outlet if the compressor

operating pressure is higher than 8.5 bar. These elements must be rated

for a flow rate of at least 370 l/min so as not to cause a drop in outlet

pressure during cutting.

5. The inside of the airbox should be coated against corrosion.

10/32

6. The compressor intake should be fitted with an efficient intake air filter,

especially for mobile compressors when operating in dusty environments.

CautionSome compressors have a built-in pressure air mixer at the

outlet. Under no circumstances must the plasma cutter be connected to

this outlet! This would contaminate the entire pneumatic system and could

damage the torch.

Connection to the central air distribution system

1. Before connecting, determine the working pressure in the system and the

extent of its fluctuation.

2. During cutting, the working pressure must be between 5.0 and 6.0 bar. To

achieve maximum cutting performance, we recommend that the pressure

does not drop below 5.5 bar.

3. Check the performance and technical condition of the central

compressor(s). The same requirements as above apply here.

4. Check the design and condition of pressure air filtration and condensate

trapping.

5. Ensure that the system is not centrally lubricated.

6. Include an additional filter and separator at the connection point closest to

the cutter. This is particularly important for older pipes made of

conventional steel pipes where the inner walls may be badly corroded. A

filter and separator is essential for systems with long ducts that pass

through cold environments where the compressed air may cool to the dew

point, causing condensation of water droplets.
