2. SAFETY INSTRUCTIONS AND WARNINGS
1. OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN
BE DANGEROUS AND HAZARDOUS TO YOURHEALTH.
2. 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.
3. Once the packing has been opened, make sure that the machine is not
damaged. If in any doubt, call the service centre.
4. This equipment must only be used by qualified personnel.
5. During installation, any electric work must only be carried out by trained
personnel.
6. The machine must be used in a dry place with good ventilation.
7. Make sure that no metal dust can be drawn in by the fan inside the
machine, as this could cause damage to the electronic circuits.
8. It is prohibited to connect more than one INVERTER generator in series or
in parallel.
9. When installing the machine, follow the local regulations on safety.
10. The position of the machine must allow easy access by the operator to
the controls and connectors.
11. When the cutting machine is operating, all its covers and doors must be
closed and well fixed.
12. Do not expose the cutting machine to direct sunlight or to heavy rain.
This equipment conforms to protection rating IP23S.
13. The operator must wear gloves, clothes, shoes, and a helmet or a
welder’s helmet, which protect and are fire-resistant in order to protect him
against electric shock, flashes and sparks from cutting.
14. The operator must protect his eyes with safety visor or mask designed for
welding, fitted with standard safety filters. He should also be aware that
during plasma cutting ULTRAVIOLET RADIATION is emitted. Therefore it is
vital that his face is also protected from radiation. Ultraviolet rays produce
the same harmful effect as sun burning on unprotected skin.
15. The operator is obliged to warn anyone near the cutting area of the risks
that cutting involves and to arrange to provide adequate protection
equipment.
16. Keep all fumes and gases from the breathing area.
17. Keep your head out of the fume plume.
18. Use an air-supplied respirator if ventilation is not adequate to remove all
fumes and gases.
19. The kinds of fumes and gases from the plasma arc depend on the kind of
metal being used, coatings on the metal, and the different processes. You
must be very careful when cutting or welding any metals which may contain

5/20
Linde AG, Linde Gas Deutschland ©
one or more of the following:
Antimony
Chromium
Mercury
Nickel
Cobalt
Arsenic
Barium
Copper
Selenium
Beryllium
Lead
Silver
Cadmium
Manganese
Vanadium
20. Always read the Material Safety Data Sheets (MSDS) that should be
supplied with the material you are using. These MSDSs will give you the
information regarding the kind and amount of fumes and gases that may be
dangerous to your health.
21. It is very important to arrange for sufficient ventilation, especially when
cutting in enclosed spaces. We suggest using suitable fume extractors to
prevent the risk of intoxication by fumes or gas generated by the cutting
process.
22. Noise can cause permanent hearing loss. Plasma arc processes can
cause noise levels to exceed safe limits. You must protect your ears from
loud noise to prevent permanent loss of hearing.
23. To protect your hearing from loud noise, wear protective ear plugs and/or
ear muffs. Protect others in the workplace.
24. Noise levels should be measured to be sure the decibels (sound) do not
exceed safe levels.
25. The operator must ensure all flammable materials are removed from the
work area to avoid any risk of fire.
26. The operator must NEVER cut containers that have previously contained
petrol, lubricants, gas or similar flammable materials, even if the container
has been empty for a considerable time. THERE IS A VERY HIGH RISK OF
EXPLOSION.
27. The operator must be aware of all the special regulations which he needs
to conform to when cutting in enclosed spaces with a high risk of explosion.
28. To prevent electric shock, we strongly suggest the following rules:
Do not work in a damp or humid environment.
Do not use the machine if its cables are damaged in any way.
Make sure that the earthing system of the electric equipment is
correctly connected and operational.
The operator must be insulated from the metal components
connected to the return wire.
The earthing of the piece being worked could increase the risk of
injury to the operator.
29. EN 60974-1 Standard: Open-circuit voltage. During the operation of the
machine, the highest voltage, with which it is possible to come into contact,
is the open-circuit voltage between the clamps. In our generator this voltage
is 380V.
30. The maximum open-circuit voltage of the plasma machines is established

6/20
Linde AG, Linde Gas Deutschland ©
by national and international standards (EN 60974-1) depending on the type
of current to be used, on its waveform and on the hazards arising from the
work place. These values are not applicable to the strike currents and those
for stabilisation of the arc that could be above it.
31. The open-circuit voltage, for as many adjustments as possible, must
never exceed the values relating to the various cases shown in the following

2.2 COMMENTS ON CONSUMABLES
2.2.1 Shield cups –Retaining cups
PARKER SCP 60
1. You can choose from two shield cups. Both have 6 holes for the
compressed air.
2. For longer life particularly when cutting at 40 A we suggest to use nozzle
SCP2530-6L.
ABICUT45
1. You can choose from two shield cups. They differ in the number of holes for
compressed air ( 4 respectively 6 holes). It is appropriate to use shield cup
748.0052.2 (35 A) for lower power, cut would be better.
2. For maximum performance it is necessary to use shield cup 748.0043.2
(45A) with six holes for air.
2.2.2 Long electrode and a long cutting tip
1. The combination of Long electrode and Long cutting tip is aimed for cutting
in angles or in spaces where standard electrode cannot reach.
2. It is possible to drag the Long cutting tip directly on the cutting material up to
thickness of 5.8 mm without the guiding spring. The Lifetime of the cutting
tip and the electrode is reduced by 30% - 50%.
2.2.3 Standard electrode and standard cutting tips

14/20
Linde AG, Linde Gas Deutschland ©
PARKER SCP 60
1. For smaller cutting thickness (carbon steel) up to 4 mm it is better to use
Cutting Tip SCP2520-06, Ø 0.65 (10-20A) in combination with electrode
SCP2504.
2. For cutting thicknesses from 4 to 6mm use Cutting Tip SCP2520-08, Ø
0.8 (20-30A). For cutting thicknesses from 6 to 8 mm use Cutting Tip
SCP2522-09, Ø 0.9 (30-40A).For cutting thicknesses over 8 mm use
Cutting Tip SCP2524-10, Ø 1,0 (40-50A).
ABICUT45
1. It is possible to drag the standard cutting tip directly on the cutting material
up to thickness of 10 mm without the guiding spring. The Lifetime of the
cutting tip and the electrode is reduced by 30% - 50%.
2. It is better to use standard cutting tip 748.0034.10 0. (Cutting Tip 0,65
Standard ABI25/45) in combination with standard electrode 748.0032.10 for
smaller cut thickness. Cut is narrower, better.
3. GETTING STARTED
3.1 FIRST STEPS
NOTEThis equipment must only be used by qualified personnel.
1. Before beginning work is necessary to connect the machine to the mains. (1
x 110-230 V, 50/60 Hz).
2. Check completeness of the mounted cutting torch.
3. Connect the compressed air quick connector to the connector on the rear
wall of the machine.
4. Connect the mains plug to the mains.
5. After turning the power switch pos. 10 the LED “ON” pos. 1 must illuminate.
6. Connect the work lead cable to the material being cut.
7. Check the input pressure. The max. input pressure is 7,5 bar, the minimal
input pressure is 4 bar.
8. Set potentiometer pos 3to the cutting power you need.
9. Fit the torch with appropriate type of cutting tip electrode and shield cup
according to the selected cutting current.

15/20
Linde AG, Linde Gas Deutschland ©
3.2 REQUIREMENTS FOR SOURCE OF COMPRESSED AIR
1. Delivered air pressure must be max. 7,5 bar and min. 4 bar.
2. Air consumption 119 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 50 l
8. No additional oiling if the pressure air is permitted. That could damage
the plasma machine and the cutting torch.
3.3 OPTIONAL AIR FILTERS
To achieve high quality cutting and to avoid serious disturbances to the torch it
is highly advised to include the air filter.

3.4 CUTTING
1. Press the torch trigger. The pilot arc will ignite. Then you have to
immediately attach the torch to the cut material. At this point begins to burn
the main arc between the torch and the material.
2. Move the torch with a constant speed. Cutting speeds vary according to
torch output amperage, the type of material being cut, and operator skill.
3. Output current setting or cutting speeds may be reduced to allow slower
cutting when following a line, or using a template or cutting guide while still
producing cuts of excellent quality
4. To achieve a good cutting quality make sure the distance between the tip
and the material is about 2 mm. The Standoff Guide ABI25/45 pos 22
located at the end of the plasma torch guarantees the distance .At a greater
distance decreases cutting power and the arc may go off. With too small
distance the torch parts will be worn off faster.
5. Plasma cutting may be done in all possible positions (vertically, horizontally,
overhead, vertical ascending and descending), but as far as possible
choose primarily horizontal cut. In other positions the operator is
increasingly threatened by flying drops of molten material.
6. We recommend starting cutting at the edge of the material. If needed to
start from the centre of the material, or to cut hole into the material, slightly
tilt the torch head and gradually it straighten into a vertical position so the
spraying material would not damage the cutting tip (see Figure 6). This
workflow must always be followed, if the thickness of material is above
above 3 mm.
7. In case of cutting in the corner or around the corner (see Figure 7), use the
long electrode and cutting tip (pos. 17 and 20). The cutting power while

17/20
Linde AG, Linde Gas Deutschland ©
using the Long cutting tip is decreased.
Fig. 6 Fig. 7
3.5 IMPORTANT RULES
1. The pilot arc burning time should be limited only to the time necessary. It
lowers the wear of the cutting tips and electrodes.
2. Never turn off the main switch immediately after finishing cutting but always
leave time to run cooling cycle to cool down the torch. Immediate turn-off
only in case of emergency.
3. Ensure a good el. Contact of the work lead clamps and cutting material.
4. Check and timely exchange cutting tips and the electrodes. Lifetime of these
parts is only a few hours of cutting time and is highly dependent on
compliance with the principles of good cutting.
5. Disconnect the machine from the mains before replacing the torch
consumable parts.
6. Unplug the machine from the mains before any intervention inside the
machine.
7. Ryval 40 PLASMA PFC is adapted for use with torch ABICUT 45. This
combination comply with EN 60974-7 Article 10.1.4. Using any other type
and design of a torch must be approved by Linde AG, Linde Gas
Deutschland.
8. Imperfect capture of condensate would cause its elimination in the area of
the cutting tip and it would prevent ignition of the pilot arc.
3.6 SOURCES OF POOR QUALITY CUTS
3.6.1 Shallow penetration of the cut
1. The cutting speed is too high. Make sure the slope of the cutting arc does
not exceed about 15 °(see Figure 8).
2. High wear of the cutting tip or electrode (see Figure 9)
3. Too large thickness of material and not adequately chosen value of current
and diameter of the cutting tip.
4. Bad contact between the work lead clamps and material.
3.6.2 Cutting arc is unstable, goes off and "shoots"
1. Worn out cutting tip or electrode
2. High pressure

18/20
Linde AG, Linde Gas Deutschland ©
3. Impurities in the pressure air
4. not captured water condensate
3.6.3 Conical cut
1. If there is a false cut (see Figure 10) turn off the machine, release the shield
cup and rotate the cutting tip about 1/4 and again try to cut.
2. Damaged cutting tip and electrode
3. The position of the torch is not perpendicular to the material
4. Too large distance form the cutting tip to the material.

Fig. 8 Fig. 9 Fig. 10
4. MAINTENANCE
1. A great care should be taken to the cutting torch. The molten material
sprays while cutting. This sputter contaminates the interior space of the
torch. The worn parts (consumables) of a plasma torch should be regularly
maintained and timely exchanged. Regularly check the condition of diffuser
channels (see diagram of the torch). If contaminated, you must clean it with
a pressure air or to replace the diffuser. Poor state of the diffuser has a
negative impact on the quality of cutting and causes very strong interference
that may cause the collapse of the machine control electronics or influence
the surrounding devices. If the cable bundle of the torch is worn out it must
be replaced immediately - danger of electrical shock.
