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 setting of the required working pressure of the gas and display of the
pressure value on the display. The proportional valve allows you to precisely set
the required pressure or gas flow and allows high accuracy and stability of
cutting. The machine is equipped with the ecological function "fan on emand". If
cooling is not required, the machine automatically shuts off the fan.
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 appropriate training.
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 six months by an authorized worker according to ČSN 331500
and ČSN 050630.
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
2. Welding gloves

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 very short 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 and other compounds, some of which are harmful to 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.

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.

5. REQUIREMENTS FOR SOURCE OF COMPRESSED AIR
1. Delivered air pressure must be max. 8,5 bar and min. 6,5 bar.
2. Air consumption minimal 240 l/min.
3. Compressed air for the plasma must be clean and dry.
4. Pressure dew point +3 °C.
5. Maximum oil content 0.1 mg/m3.
6. Maximal size of solid particles 15 microns.
7. The minimal size of an air tank is 100 l.
8. No additional oiling if the pressure air is permitted. That could damage the
plasma machine and the cutting torch.
Note Some compressors have a built-in compressed air lubricator
at the outlet. The plasma cutter must never be connected to this output!
This would contaminate the entire pneumatic system and damage the
Torch.
CONNECTION TO CENTRAL DISTRIBUTION
1. Before connecting, determine the working pressure in the system and the
extent of its fluctuations
2. When cutting, the working pressure must be in the range of 5.0 - 6.0 bar.
To achieve maximum cutting power, we recommend that the pressure
does not fall below 5.5 bar (for gouging 4,8 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 the compressed air filtration and
condensate trap.
5. Make sure the system is not centrally lubricated.
6. Insert an additional filter and separator at the connection point as close as
