CAUTION!
BEFORE INSTALLING, OPERATING OR CARRYING OUT MAINTENANCE ON THE
PLASMA CUTTER, READ THE CONTENTS OF THIS MANUAL CAREFULLY, PAYING PAR-
TICULAR ATTENTION TO THE SAFETY RULES.
In the event of these instructions not being clear, please contact your supplier.
CONGRATULATIONS ON YOUR NEW PURCHASE!
YOU ARE NOW IN THE POSSESSION OF ONE OF THE SAFESTAND MOST TECHNOLOGI-
CALLYADVANCED PLASMA CUTTERS ON THE MARKET.
FOLLOW OUR SUGGESTIONS AND YOU WILL BE GUARANTEED SAFE AND PROBLEM-
FREE OPERATION.
Your plasma cutting unit is ¿tted with sophisticated safeguards which block
functioningandthereforethecuttingoperationsuntilallthesafetyconditions
arepresent.Theplasma cutting technique requiresdangerouslyhighvoltage
for pilot arc starting and during cutting, therefore the following safety rules
must be observed with great care.
ELECTRICITY
1-Makesurethat the unit is earthed and that thesupplylinehasanadequate
earth connection.
2-Make sure that the work bench has a satisfactory earth connection.
3-Avoid contact between the metal bars being cut and bare skin or damp
clothes.
4-Do not lean on the piece being cut or hold it in your hands.
5-Do not carry out cutting operations in damp environments or on wet surfaces.
6-Do not use the unit if the torch or cables appear damaged.
7-Always turn the unit off before replacing the electrode, the nozzle or the spreader tip of the torch.
8-Always switch the unit off and remove the power cable from the mains socket before carrying out
any maintenance inside the unit.
EYE AND BODY PROTECTION
One of the hazards during the cutting process is the emission of electromagnetic waves due to the
electric arc. The length of these waves ranges from infrared to ultraviolet. If these rays hit the eyes,
they can cause various complaints such as conjunctivitis, burns to the retina, deterioration of sight,
etc. Moreover a high concentration of ultraviolet rays can burn the skin. It is, therefore, extremely
important that the operator uses adequate safety equipment and clothing, such as:
SAFETY RULES AND GENERAL WARNINGS
INTRODUCTION
CAUTION!
Repairs, maintenance and operation of the unit should be carried out by trained personnel
who are aware of the risks caused by the high voltage needed to operate the plasma cutting
unit. The operator should work in compliance with current standards and abide by all safety
regulations.
CAUTION!
If during the cutting operation a slight electric shock is felt, stop work immediately and do not
use the unit until the fault has been discovered and resolved.

15
1-Split or leather gloves
2-Split or leather aprons
3-Shin-guards
4-Safety shoes
5-Safety mask (or even better helmet) large enough to cover the whole
of the face, equipped with safety lenses able to ¿lter all the radiation and
reduce the intensity of the light absorbed by the eye.
CAUTION!
A further hazard for eyes is the risk of splinters or particles which may be deta-
ched during the cutting operations or during grinding,
brushing or hammering away of the scale.
Always wear goggles or protective shields with transparent lenses during
these operations to prevent splinters or other foreign bodies from entering the eye.
IMPORTANT:safety screensshouldbe installed around the cutting area toprotect other people, who
may be working in adjacent areas, from the radiation given out by the arc.
FIRE HAZARDS
1-Prevent sparks or hot scale from producing Àames
2-Remove inÀammable or combustible materials from the cutting area.
3-Make sure that ¿re-¿ghting equipment is located near the work area.
4-Situate the unit in an area where the air can be sucked in and exhausted from the grilles on the panel
CAUTION!
Do not cut fuel or lubricant containers even if these are empty.
Do not cut containers or casings which contain inÀammable material.
Never cut in environments which are polluted by inÀammable gas or combustible liquid va-
pours (such as petrol).
CUTTING FUMES AND GASES
Harmful fumes and metallic powders are produced during the cutting operation. Metals which are
painted or coated or which contain mercury, cadmium, zinc, lead and graphite may produce harmful
concentrations of toxic fumes during cutting.
To protect the operator or other persons from exposure to possible toxic fumes, fume respirators
should be worn and work areas should be adequately ventilated.
When working in enclosed environments, suction units should be ¿tted below the cutting area.
CAUTION!
When halogenated solvents or degreasing agents are present, the material to be cut should
be cleaned properly to prevent the formation of toxic gases. Some chlorinated solvents may
decompose in the presence of the radiation given out by the arc and may generate phosge-
ne gas.
CAUTION!
Never, under any circumstances, look at an electric arc without eye protection.

16
NOISE
Noise is generated during the cutting process. The noise level depends on the cutting parameters used.
CAUTION!
Noise can damage hearing
Wear adequate hearing protection.
BURNS
The operator should be adequately protected during cutting operations. This should be routine practice.
CAUTION!
Do not point the torch jet at people or foreign bodies.
EMC
Before installing the plasma cutting unit, carry out an inspection of the surrounding area, observing
the following guidelines:
1-Make sure that there are no other power supply cables, control lines, telephone leads or other
equipment near the unit.
2-Make sure that there are no radio receivers or television appliances.
3-Make sure there are no computers or other control systems.
4-Make sure that there is no-one with a pacemaker or hearing aid in the area around the unit.
5-Check the immunity of any other equipment operating in the same environment. In certain cases
additional protective measures may be required.
Interference can be reduced in the following ways:
1-If there is interference in the power supply line, an E.M.C. ¿lter should be inserted between the
mains and the unit.
2-Theoutputcablesoftheunitshould be shortened; these should be kept close together and stretched
along the ground.
3-All the panels of the unit should be correctly closed after carrying out maintenance.
GENERAL INFORMATION
PLASMA ARC AND BASIC PRINCIPLES FOR THE PERFORMANCE OF PLASMA CUTTING
¥Plasma is a gas that is heated to an extremely high temperature and ionised so that it becomes
a conductor of electricity.
¥This cutting procedure utilises the plasma to transfer the electric arc to the metal workpiece,
which is melted by the heatand then separated.
¥The torch uses compressed air from a single source, for both the plasma and cooling and pro-
tective gas.
¥The start of the cycle is determided by an arc, called the pilot arc, which is struck between the
mobile electode(negative polarity) ab dthe torch nozzle (positive polarity) due to the short circuit
between these two elements.
¥When the torch is brought into direct contact with the workpiece to be cut (connetcted to the
positive polarity of the power source) the pilot arc is transfered between the electrode and the
workpiece itself thus striking a plasma arc, also called cutting arc.
¥The duration of the pilot arc is set in the fatcory at 3 seconds; if the transfer has not been made
within this time, the cycle is automatically stopped except for the cooling air which is kept on.

17
A source of clean, dry air or nitrogen must be supplied to your plasma cutting unit. The supply pres-
sure must be between 72.5 and 150 psi (5 and10.3 bar). The Àow rate is approximately 3.5 cu.ft./
min. (100L/min.). Failure to observe these precautions could result in excessive operating tempera-
tures or damage to the torch.
An air regulator is included with the unit with optimum pressure setting set to 65 PSI, 4.5 Bar.
Note: the regulator should never be set above 6 bar.
MANUAL PURGE
Oil in the air is a severe problem and must be avoided.
The unit is also equipped with an air ¿lter which captures
water and oil vapor.
Model 30A - 40A: The vapor collected can be drained
out turning the drain knob located on the air ¿lter. Three
Position Drain knob, select the desired position:
1. Open
2. Open when no air pressure, closed when air pressu-
re. The drain knob should not be left in this position
during cutting operations.
3. Closed
Model 45A: water contained in the ¿lter glass can be drained by pushing upward the drain connector.
Note: The unit will not operate if the input air pressure is below 55 PSI, 3.8 Bar.
POWER SUPPLY CONNECTION
Themachine must be connectedtoaLine-Neutral system witha“PE”protected grounding wire. Check
that the relevant socket terminal is actually connected to the distribution system grounding.
CONNECTION TO GROUND CABLE
Connect the dinse plug to the socket and the work cable clamp to the piece to be cut or to the metallic
workbench. Take following precautions:
¥Verify that there is a good electrical contact particularly if insulated or oxidated coated sheets
are cut.
¥Make ground connections as close as possible to the cutting area. The use of the metallic struc-
tures which are not part of the workpiece, such as the return cable of the cutting current, may
endanger the safety system and give poor cutting results.
¥Do not make a ground connection on the piece which has to be removed.
WARNING!: Before starting the cutting operations verify that the parts are properly assembled
by inspecting the head of the torch as shown on paragraph “Torch Maintenance”
LOCATION AND HANDLING OF THE POWER SOURCE
¥Choose location verifying that there is a good air Àow and no dust, smoke or gas is present.
¥Make sure that obstacles do not prevent the cooling air Àow out of front and rear openings of
the machine.
¥Arrange an open space of at least 5m around the machine.
¥In the case the machine has to be moved, always disconnect the plug from the outlet and gather
the cables and pipes so as not to damage them.

CUTTING OPERATION
PRELIMINARIES
WARNING: unplug the unit from the power supply before assemble or disassemble piled parts,
single parts, parts of the torch, torch assemblies or cables.
¥Check and follow instructions as foreseen in the paragraphs “Safety and Installation” of the
present instructions manual.
PARTS OF THE TORCH
¥Check the torch for proper assembly. Install proper torch parts for the desired application (refer
to Section called Torch Consumable Parts Selection). NOTE: The power supply will not opera-
te unless the torch shield cup is fully seated against the PIP (Parts in Place) pins in the torch
head.
INPUT POWER
¥Check the power source for proper input voltage.
¥Make sure the power source meets circuit protection and wiring requirements.
¥Plug unit in and close main disconnect switch to supply primary power to the system.
GROUND CABLE
¥Check for a solid ground cable connection to the workpiece.
AUTOMATIC PURGE SYSTEM
30A - 40A model
¥Place the ON/OFF switch to the ON position. The ON light will Àicker momentarily as the system
powers up and then stays on.Activate the torch button to initiate gas purge (pre-Àow) to remove
any condensation that may have accumulated in the torch and leads while the system was shut
down. When the gas purge is complete, pilot arc will be initiated.
45A model
¥Place the ON/OFF switch to the ON position.Activate the torch button to initiate gas purge (pre-
Àow) to remove any condensation that may have accumulated in the torch and leads while the
system was shut down. When the gas purge is complete, pilot arc will be initiated. To cool torch
handle or to further remove condensation in the torch and leads push the torch gas purge button
on the front panel of the unit.
WARNING
Do not initiate pilot arc during adjustment.
CHECKING AIR QUALITY
¥To check air quality, deactivate the torch (post-Àow) and place ¿lter lens in front of the torch.Any
oil or moisture in the air will be visible on the lens. DO NOT initiate pilot arc while checking air
quality.

CUTTING
A. Cutting with a Hand Torch
¥Thetorchcanbecomfortablyheldinonehandorsteadiedwith two hands. Choose the technique
that feels most comfortable and allows good control and movement. Position the index ¿nger or
thumb to press the control switch on the torch handle.
¥For edge starts, hold the torch perpendicular to the workpiece with the front of the tip on the
edge of the workpiece at the point where the cut is to start. - Fig.A. For piercing, angle the torch
slightly to direct sparks away from the torch until the pierce is complete. Fig. B
Fig. A Fig. B
¥For drag cuts keep the torch in contact with the workpiece. For standoff cutting, hold the torch
2-3 mm from the work.
¥With the torch in starting position, press the control switch. After an initial gas purge (pre-air),
the pilot arc will come on and remain on for 3 seconds until the cutting arc starts.
¥Once on, the main arc remains on as long as
thecontrolswitch is held down, unless thetorch
is withdrawn from the work or torch motion is
too slow. Keep moving while cutting. Cut at a
steady speed without pausing. Maintain the
cutting speed so that the arc lag is about 30°
behind the travel direction. Fig. C
If the cutting arc is interrupted, and the torch
triggerisstill pressed, the pilot arc comes back
on automatically for 3 seconds.
¥To shut off the torch simply release the control switch. When the switch is released a post-Àow
will occur. If the torch trigger is pressed during the post-Àow, the pilot arc will restart.
B. Piercing with a Hand Torch
Note: Recommended maximum piercing capacity is 2mm. If necessary to make a cut on a
metal sheet with a tickness more than 2mm without an edge start, make a hole ø 6mm at
least using an electric drill to start cutting.
¥When piercing with a hand torch, tip the torch
slightly so that blowback particles blow away
from the torch tip (and operator) rather than
directly back into it. Fig. B
¥Completethepierce offthe cutting line and then
continue the cut onto the line. Hold the torch
perpendicular to the workpiece after the cut is
complete. Fig. D
¥Clean spatter and scale from the shield cup and the tip as soon as possible. Spraying or dipping
the shieldcup in anti-spatter compound will minimize the amount of scale which adheres to it.
C. Grates Cutting
To cut grates it is suggestable to set cutting current between 20 - 34A.

TORCH
Periodically, according to its use or to cutting faults verify wear of the parts connected to plasma arc:
Shield Cup:
Unscrew manually from head of the torch. Clean throughly abd replace if damaged (burns, distortions or
cracks). Verify integrity of superior metal sector (actuator torch safety).
Tip:
Check wear of plasma arc hole and of inner and outer surfaces. If the hole is widened compared to its
original width or if it is damaged, replace tip. If surfaces are particularly oxidated clean them with extra
¿ne abrasive paper.
Air Distribution Ring:
Verify the are no burns or cracks or that airÀow holes are not obstructed. If damaged, replace immediately.
Electrode:
Replace electrode when crater settling on emitting surface is about 2mm.
WARNING!
¥Before making any operation to the torch let it cool at least all along the “postgas” period.
¥Except for particular cases it is advisable to replace electrode and tipAT THE SAME TIME.
¥Respect assembly order of torch parts (reserved compared to disassemblage).
¥Be carefull that distributing is assembled properly.
¥Reassemble shield cup screwing tightly and manually.
¥Never assemble shield cup without having assembled electrode distributing ring and tip befo-
rehand.
