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 105 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 105 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 105 PLASMA CNC is designed for high-quality cutting of materials
up to 40 mm thick mild steel. Productive cutting of carbon steel can be to a
thickness of 32 mm. At lower demands on the quality of the cut can be cut
through (separate) the material thickness to 50 mm. Maximal piercing is 22 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.

SYSTÉM SV-FIT
The SV-FIT system allows great variability when using different ends of welding
torches or allows to extend the torch length from the standard 9 m or 12 m using
Cable koax. extension # 7088.
Pic. 4 SV-FIT system
VITALITY OF CONSUMABLE PARTS
The need to change consumables on your torch depends on the thickness of the
material being cut, the length of the cut, the air quality (presence of moisture, oil
and dirt), the way the cut is started (side or puncture), the appropriate piercing
height, cutting mode (solid or perforated).

15/30
ALFA IN a.s © www.alfain.eu
In general, the current set of consumables lasts an average of 1 to 3 hours of
cutting (ignited arc). Under normal conditions, the nozzle wears first when cutting
by hand, the electrode lasts about half as long as once.
When replacing o-ring 5790, lubricate the o-ring area with lubricant 7101.
HOW TO CHOOSE THE RIGHT CONSUMABLE PARTS
Torch SVH-105 use the same consumables that are protected, so the nozzles
can be pulled over the cut material.
For the best cut quality, it is necessary to use suitable sets of consumable
parts. The individual assemblies by power and type, including order numbers,
are listed in the table below.

8. FIRST STEPS
Commissioning of the machine must be in accordance with the technical data
and operating conditions.
Note This equipment must only be used by qualified personnel.
1. Before beginning work is necessary to connect the machine to the mains.
2. Check completeness of the mounted cutting torch.
3. Fit the burner and secure the burner well by turning the nut clockwise.
4. Connect the compressed air on connector A7 on the rear wall of the
machine.
5. Connect the compressed air on connector A6 on the rear wall of the
machine.
6. SVAROG 105 PLASMA has a pressure regulator A5 on the rear panel.
7. Set the pressure with the regulator on the rear panel of the machine to 5.5
bar.
8. After turning on the ON / OFF switch A8 the display will illuminate
9. Connect the work lead cable to the material being cut and to the
connector A1.
10. Check up the input air pressure (min 5,0 bar, max 8,5 bar) and make
a regulation if necessary.
11. Set potentiometer to the cutting power you need.
12. Fit the torch to the appropriate nozzle diameter according to the
selected cutting current.
13. Press the trigger on the cutting torch, the pre gas will flow for 1 s.
14. The pilot arc will start.
15. Shift the torch with the pilot arc close to the material, the pilot arc
will change to cutting arc automatically. If you do not start cutting within
2 s, the arc will snuff off. If the torch delays during the cutting from the
material, the arc will snuff off. In case that the machine is in mode
Cutting material with gaps – switch A5 position , cutting arc will
change to pilot arc and if you do not start cutting within 2 s, this arc will
snuff off.
16. To finish the cutting process, release the torch trigger.
REQUIREMENTS FOR SOURCE OF COMPRESSED AIR
1. Delivered air pressure must be max. 8,5 bar and min. 5,0 bar.
2. Air consumption minimal 320 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.

18/30
ALFA IN a.s © www.alfain.eu
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
burner.
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.
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
possible to the cutter. This is especially important for older distribution
systems made of conventional steel pipes, where the inner walls can be
considerably corroded. It is necessary to use a filter with a sludge trap in
systems with long distributions that pass through a cold environment,
where compressed air can cool to the dew point and thus condense water
droplets.
BALANCE AIR FILTER FOR SVAROG 105 PLASMA
In order to achieve high cutting quality and to avoid serious faults on the torch,
it is strongly recommended that a filter be always included in the inlet - Fig. 4.
Pos. Code Description
25 5304 Filter - set AT 1000 k SVAROG PLASMA

Pic. 5 Air filter
9. CUTTING
1. The burning time of the pilot arc must be limited to the time necessary. The
team wear of the nozzle and electrode is reduced. Frequent idling starts
that the nozzle and electrode are loaded and the pilot arc resistance ballast
could be played.
2. After cutting, never switch off the machine with the main switch, but always
let the so-called torch cooling cycle run. Perform an immediate shutdown
only in an emergency.
3. Compressed air has a decisive influence on the quality of the cut, the
service life of the nozzles, electrodes and the entire burner. Make sure that
the pressure value is set correctly: the optimum value is 5.5 bar,
fluctuations in the range of 5.0 - 6.0 bar are permissible. The air must be
free of mechanical impurities, oil and water condensate. These
contaminants reduce the quality of the cut, cause instability and the arc to
go out, and can damage the torch. The compressed air source must
therefore be equipped with efficient filtration and a reliable oil and water
condensate separator. The use of a filter and separator built into the
SVAROG 105 PLASMA as the only stage of air conditioning is completely
insufficient. In cases where the compressor sucks in high-humidity air,
which results in the need for frequent desilting of the pressure vessel, it is
necessary to include another effective sludge trap as the 3rd stage in the
supply. The collected condensate must be drained daily from all sludge
traps and compressor pressure vessel. Pay attention to a good el. contact
of earthing pliers and material.
The nozzle and electrode must be inspected and replaced in a timely

20/30
ALFA IN a.s © www.alfain.eu
manner. The service life of these parts is only a few hours of cutting time and
is strongly dependent on following the correct principles when cutting.
Notice
1. When the air pressure is low, control indicator E13 on the control panel
lights up and further operation is blocked.
2. If the machine overheats during cutting, error message E02 on the control
panel will illuminate and its further operation will be blocked.
3. Disconnect the machine from the mains before replacing the burner parts.
4. Disconnect the machine from the mains before carrying out any work
inside the machine.
5. The machine is adapted for use with Plasma Torch SVH-125. In this
combination, it forms a safe system in accordance with ČSN EN 60974-7,
Article 10.1.4. The use of any other type and design of burner must be
consulted with ALFA IN a.s.
6. SVAROG 105 PLASMA must not be connected directly to a pressure
source higher than 8.5 bar or to cylinders! Connection to such sources is
only possible via a suitable pressure reducing valve, which is tested for the
corresponding inlet pressure and flow.
7. Incomplete trapping of condensate will cause its condensation in the
burner nozzle area and will prevent the pilot arc from igniting.
THE MOST COMMON MISTAKES IN MACHINE CUTTING
Insufficient penetration of the cut, when cutting there is an excessive
amount of sparks on the upper side of the sheet. Possible causes:
1. The sheet has a dirty surface from rust or paint.
2. Consumables are worn. For optimal machine cutting, replace electrodes
and nozzles at the same time.
3. High cutting speed.
4. Current is set too low.
5. Large material thickness and improperly selected value of cutting current
and nozzle diameter.
Bad el. contact between the grounding clamp and the material.
The pilot arc will run, but there will be no ignition
1. There is poor electrical contact between the cut sheet and the ground
clamp.
2. Torch cutting height too high.
The cutting arc is unstable, goes out and „shoots“
1. Worn nozzle or electrode, replace both.
2. High air pressure.
3. Polluted air.
4. Uncaptured water condensate.
