CAUTION!
BEFORE INSTALLING, OPERATING OR CARRYING OUT MAINTENANCE ON THE
PLASMA CUTTER, READ THE CONTENTS OF THIS MANUAL CAREFULLY,
PAYING PARTICULAR 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 POSSESSION OF ONE OF THE SAFEST AND MOST TECHNOLOGICALLY
ADVANCED PLASMA CUTTER ON THE MARKET.
FOLLOW OUR SUGGESTIONS AND YOU WILL BE GUARANTEED SAFE AND PROBLEM-FREE
OPERATION.
SAFETY RULES AND GENERAL WARNINGS
INTRODUCTION
Your plasma cutting unit is tted with sophisticated safeguards which block functioning and therefore the
cutting operations until all the safety conditions are present. The plasma cutting technique requires
dangerously high voltage for pilot arc starting and during cutting, therefore the following safety rules must
be observed with great care:
ELECTRICITY
1 - Make sure that the unit is earthed and that the supply line has an adequate earth connection
2 - Make sure that the work bench has 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 cables appear damaged.
7 - Always turn the unit off before replacing the electrode, the nozzle or any other torch consumable.
8 - Always switch the unit off and remove the mains power cable from the main socket before carrying out
any maintenance inside the unit.
CAUTION:
Only qualied technicians are authorized to undertake the repair task of this
cutting equipment in case of machine fault.
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.

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:
1 - Leather gloves
2 - Leather aprons
3 - Shin guards
4 - Safety shoes
5 - Safety mask (or even better a 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:
Never, under any circumstances, look at an electric arc without eye protection.
CAUTION:
A Further hazard for eyes is the risk of splinters or particles which may be detached 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 welding screens should be installed around the welding area to protect other people,
who may be working in adjacent areas, from the radiation given out by the arc.
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, 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 phosgene gas.
FIRE HAZARDS
1 - Prevent sparks or hot scale from producing ames
2 - Remove ammable or combustible materials from cutting area.
3 - Make sure that the re-ghting equipment is located near work area.
4 - Situate the unit in a 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 they are empty.
Do not cut containers or casings which contain ammable material
Never cut in environments which are polluted by ammable gas or combustible liquid vapours
(such as petrol)

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 are, observing the
following guidelines:
1 - Make sure that there are no other power supply cables, control line, 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:
(5a) - If there is interference in the power supply line, an E.M.C lter should be inserted between the main
and the unit.
(5b) - The output cables of the unit should be shortened; these should be kept close together and stretched
along the ground.
(5c) - All the panels of the unit should be correctly closed after carrying out maintenance.
DESCRIPTION OF SAFEGUARDS
Our plasma cutting units are supplied with the following devices.
1 - Thermal protection devices which are installed at the points most subject to high temperatures such as
the power transformers and the rectifying units. A yellow light on the front panel lights up when the thermal
protection device intervenes.
2 - Electric shock protection device which prevents the operator from coming into contact with the live parts
of the torch (such as the electrode) This consists in a safety device built into the body of the torch which
breaks the main power circuit when the end part of the torch is removed to replace the electrode or the tip.
CAUTION:
Pneumatic protection device which prevents damage to the torch due to operation with little or no air supply
is not supplied on this machine. Therefore great care must be taken to ensure that the machine is always used
with the correct clean dry air pressure at 4.8 bar 90/lt per min.
