3.1. GENERAL SAFETY WARNINGS
WARNING: your safety depends on you!!!
- Follow all safety rules carefully.
- It is your duty to protect yourself and others from the
risks of welding operations.
- The operator is responsible for his own safety and
that of those in the work area. He must therefore
know all the safety rules and observe them.
Nothing can replace common sense!!!
IMPORTANT: Before operating the machine, care-
fully read the instructions contained in this man-
ual and follow them thoroughly.
The manufacturer has made every effort to design
this machine and to make it as INTRINSICALLY SAFE
as possible.
The manufacturer has also equipped the machine
with all the protective and safety devices considered
necessary. Finally, it has provided enough informa-
tion for it to be used safely and correctly.
IMPORTANT: This information must be scrupu-
lously followed.
The user may chose to appropriately add to the infor-
mation provided by the manufacturer with addition-
al processing instructions, which, obviously, do not
contradict that contained in this Instruction Manual,
in order contribute to safe machine use.
For example, you must pay close attention to the
clothing that anyone working on the machine is
wearing:
•Avoid using clothes with hooks that can remain
attached to parts of the machine;
•Avoid using ties or other fluttering clothing parts;
•Avoid wearing bulky rings or bracelets that may
get caught in parts of the machine.
Whenever necessary, further recommendations for
use will be provided in the Manual for the user re-
lated to preventive measures, personal protective
equipment, information to prevent human error and
any reasonably foreseeable prohibited behaviour.
It is, however, essential to diligently follow the follow-
ing indications:
•It is absolutely forbidden to operate the machine
automatically with the fixed and/or mobile guards
removed;
•It is strictly prohibited to disable the safety mech-
2.5. INFORMATION
ON TECHNICAL ASSISTANCE
The machines are covered by a warranty, as provided
for in the general conditions of sale.
If during the warranty period you experience a mal-
function or failure of the machine parts, which fall un-
der the cases covered by the warranty, the manufac-
turer, after the necessary machine checks, will repair
or replace defective parts.
The goods travel at the customer's risk; product dam-
age caused by transportation or unloading is not
covered by the warranty. All equipment and consum-
ables supplied with the product are also excluded
from the warranty.
It is reminded that any modifications carried out by
the user, without the express written consent of the
manufacturer, will void the warranty and free the
manufacturer from any liability for damage caused
by a defective product.
This applies in particular to alterations made to safety
devices that reduce their effectiveness.
The same considerations apply when using non-orig-
inal spare parts or those different to the ones explicit-
ly specified by the manufacturer.
For these reasons, we recommend our customers to
always contact our Customer Service.
2.6. PREPARATION BY THE CUSTOMER
Unless otherwise agreed in the contract, the follow-
ing are normally the Customer's responsibility:
•Room preparations, including any building work
and/or ducting systems required;
•Electrical supply of the equipment, in compli-
ance with the standards in force in the country
of use. Particular care must be given to the pro-
tective conductor commonly known as "earth-
ing" and to the efficiency of the circuit breaker
installed to protect the power outlet. It is the pur-
chaser's responsibility to keep the above system
adequately efficient, in compliance with current
accident prevention regulations.
•Consumables or material normally subject to
wear;
•Equipment unloading at delivery and the conse-
quent liabilities.

and body dry.
- Do not work in damp or wet environments. Do not
lean on the piece to be welded.
- If you have to work near or in an area at risk, use all
possible precautions.
- If you also feel a little electric shock, stop welding
immediately; do not use the device until the prob-
lem is identified and resolved.
- Provide an automatic wall switch, of adequate ca-
pacity and possibly in the vicinity of the machine,
to immediately cut off the device in the event of
an emergency situation.
- Frequently inspect the power cord.
- Disconnect the power cord from the mains be-
fore working on the cables or before opening the
machine.
- Do not use the machine without the protective
bulkheads.
- Always replace any damaged parts of the machine
with original materials.
- Never bypass machine safety devices.
- Make sure that the power supply line is equipped
with an efficient earth socket.
- Make sure that the work bench and the work piece
are connected to an efficient earth socket.
- Never electrically and simultaneously touch "hot"
parts of pliers connected to two welders because
the voltage between the two can be the total of
the no-load voltage of both welding machines.
- Any maintenance must be performed only by ex-
pert personnel, aware of the risks due to the volt-
ages necessary for the operation of the equipment.
B) Radiation
Ultraviolet radiation, emitted from the electric arc,
can damage the eyes and burn the skin.
Follow the instructions below:
- Wear appropriate clothing and protective masks.
- DO NOT use CONTACT LENSES!!! The intense heat
emanating from the electric arc could stick them
to the cornea.
- Use masks with lenses, with a minimum DIN 10 or
DIN 11 protection grade.
- Protect people near the welding area.
- REMEMBER: The arc can blind or damage your
eyes. The arc is dangerous up to a distance of 15
metres. Never look at the arc with the naked eye!

incandescent parts.
- Ensure that appropriate fire protection devices are
available near the work area.
- Remove flammable and combustible materials
from the work area and the surrounding area
(minimum 10 metres).
- Do not weld/cut fuel and lubricant containers,
even if empty; these must be carefully cleaned be-
fore being processing.
- Allow the piece to cool before touching it or put-
ting it in contact with combustible or flammable
materials.
- Do not work on parts with cavities containing
flammable materials.
- Do not operate in atmospheres with high concen-
trations of combustible vapours, flammable gases
or dust.
- Always check the work area thirty minutes after
the end of work to ensure that there are no fires.
- Do not keep combustible materials such as light-
ers or matches in your pocket.
F) Burns
Protect the skin against burns caused by ultraviolet
radiation emitted by the electric arc, by sparks and
slag from molten metal, using fireproof clothing,
which covers all exposed surfaces of the body.
Wear protective clothing and welder gloves, head-
gear and high shoes with safety tip. Button the shirt
collars and pocket flaps and wear trousers without
cuff to avoid the entry of sparks and slag.
Wear a mask with protective glass on the outside and
adiactinic glass filter inside. This is MANDATORY for
welding/cutting operations, in order to protect the
eyes from radiant energy and volatile metals. Replace
- Prepare the welding area so as to reduce reflection
and transmission of ultraviolet radiation: paint
walls and exposed surfaces black to reduce reflec-
tion, installing protective screens or curtains, to
reduce ultraviolet transmissions.
- Replace the mask lenses when they are damaged
or broken.
C) Welding wire
Attention: the welding wire can cause perforated
wounds.
- Do not press the button on the welding torch be-
fore carefully reading the instructions for use.
- Do not point the torch towards parts of the body,
other people or metals, when mounting the weld-
ing wire on the welding machine.
D) Explosions
- Do not weld above or near pressurised containers.
- Do not weld in an atmosphere containing explo-
sive powders, gases or vapours.
This welder uses inert gases such as CO2, ARGON, or
ARGON + CO2 mixtures to protect the arc, therefore it
is necessary to pay the utmost attention to:
1) Cylinders:
- Handle or use pressurised cylinders in accordance
with the regulations in force.
- Do not connect the cylinder directly to the ma-
chine's gas pipe, without using a pressure regulator.
- Do not use cylinders that leak or are physically
damaged.
- Do not use cylinders that are not well secured to
the welding machine or to suitable supports.
- Do not transport cylinders without the valve pro-
tection fitted.
- Do not use cylinders whose contents have not
been clearly identified.
- Do not put the cylinder in electrical contact with
the arc.
- Do not expose cylinders to excessive heat, sparks,
molten slag or flames.
- Do not tamper with the cylinder valves.
- Do not attempt to unlock blocked valves with
hammers, keys, tools or other systems.
- Never delete or alter the name, number or other
markings on the cylinders. It is illegal and dangerous.
- Do not lift the cylinders from the ground by hold-
ing them by the valve or by the cap, or by using
chains, slings or magnets.
- Do not attempt to mix any gas inside the cylinders.
- Never refill the cylinders, but have them refilled by
specialised companies.
- Do not modify or exchange the cylinder fittings.

the operation is completed and before restarting the
machine.
I) Noise
These welders do not in themselves produce any
noise exceeding 70 dB. Arc welding processes can
produce noise levels above this limit. Therefore, users
must implement the precautions required by law.
Ear plugs should be used when working overhead or
in a small space.
A rigid helmet should be used when others work in
the area above.
Welders should not use flammable hair products.
WARNINGS ABOUT ELECTROMAGNETIC COMPAT-
IBILITY
Although these welding machines have been built
according to the regulations, they can generate elec-
tromagnetic disturbances, that is disturbances to the
telecommunication systems (telephone, radio, televi-
sion) or to the control and safety systems. Read the
instructions carefully to eliminate or minimise inter-
ference.
ATTENTION: the welding machine has been de-
signed to work in an industrial environment,
therefore, to operate in domestic environments it
may be necessary to observe special precautions
in order to avoid possible electromagnetic inter-
ference.
You must install and use the welding machine accord-
ing to the manufacturer's instructions. If electromag-
netic interference is detected, countermeasures must
be taken to eliminate the problem, possibly using the
manufacturer's technical assistance. In any case, do
not modify the welding machine without the manu-
facturer's approval.
Work area control to prevent E.M. interference
Before installing the welding machine it is necessary
to check the work area to detect the existence of ser-
vices that could malfunction in the event of electro-
magnetic disturbances.
Below is a list of services to consider:
a) Power cables, control cables, transmission system
and telephone cables that pass near the welding
machine.
b) Radio or television transmitters and receivers.
c) Computer or control equipment.
d) Safety and industrial process control equipment.
e) Calibration and measurement instruments.
f) Check the level of electromagnetic immunity of
the equipment operating in the work area.
the protective glass if it is broken, pitted or spotted.
Avoid oily or greasy clothes; a spark could ignite
them. Incandescent metal parts, such as work pieces,
should always be handled with gloves.
First aid equipment and a qualified person should be
available for each shift, unless there are health facili-
ties nearby for immediate treatment of eye and skin
burns.
G) Fumes
Welding/cutting operations produce harmful fumes
and metal dust, which can damage health:
- Do not work in spaces without adequate ventila-
tion. Keep your head out of the fumes.
- In closed environments, use suitable exhaust fans.
If ventilation is not adequate, use suitable respi-
rators.
- Clean the material to be welded/cut if there are sol-
vents or halogen degreasers, which give rise to toxic
gases. During work, some chlorinated solvents can
decompose in the presence of radiation emitted by
the electric arc and produce phosgene gas.
- Do not weld/cut coated metals or those contain-
ing lead, graphite, cadmium, zinc, chromium,
mercury or beryllium, unless a suitable respirator
is available.
The electric arc generates ozone. Prolonged expo-
sure, in environments with high concentrations of
ozone, can cause headaches, irritation of the nose,
throat and eyes and severe congestion and chest
pain.
IMPORTANT: DO NOT USE OXYGEN FOR VENTILA-
TION!!!
Gas leaks must be avoided in small spaces. Large gas
leaks can dangerously change the oxygen concentra-
tion.
Do not place cylinders in small spaces.
DO NOT WELD or CUT where solvent vapours can
be drawn into the welding atmosphere or if radiant
energy can penetrate into atmospheres containing
even tiny amounts of trichloroethylene and perchlo-
rethylene.
H) Moving parts can cause damage
Moving parts, such as the fan, can cut fingers and
hands and catch clothes.
Keep all doors, covers and guards closed and securely
in place.
Protections and coverings can be removed, for possible
maintenance and checks, only by qualified personnel.
Keep hands, hair, loose clothing and tools away from
moving parts.
Refit the covers and guards and close the doors when
1.995.202 EN - Rev. 1.112
NOVATIG 325 DC - NOVATIG 505 AC/DC
G.R.W.

C) Cables
Cables must be kept as short as possible and must be
placed close to each other and passed on the floor or
as low as possible.
D) Work piece earthing
The earth connection of the work piece can reduce
electromagnetic emissions in some cases.
The operator must pay attention to avoid that the
earthing of the piece is not a source of danger for
people and damage to the equipment. Where nec-
essary, earthing must be carried out with a direct
connection between the work piece and the ground,
while in countries where this is not permitted, the
connection must be made using a capacitor in ac-
cordance with the regulations of the country.
E) Shielding
Cable and equipment shielding in the work area can
reduce interference. Shielding of the entire welding
or cutting installation can be considered for special
applications.
F) Equipotential connections
The equipotential connections of all metal compo-
nents in and near welding installations should be
considered.
In any case the metal components connected to the
piece to be welded will increase the risk for the op-
erator to receive an electric shock from the simulta-
neous contact with these metal components and the
electrode. The operator should be isolated from all
these metal components rendered equipotential.
Checks and inspections
Checks must be carried out by a qualified technician
or a qualified and authorised technician; they must
be visual and functional, with the aim of guarantee-
ing the safety of the machine.
They include:
•inspection of all supporting structures, which
must not show any signs of cracking, breakage,
damage, deformation, corrosion, wear or altera-
tion to the original characteristics;
•checking all mechanical parts;
•inspection of all the safety devices installed on the
machine;
•ll connections with pins and screws;
•inspection of the machine operations;
•inspection of the machine status;
•verification of the correct operation and efficiency
of the electrical system;
•checking the seal and efficiency of the pneumatic
and/or hydraulic system.
g) The health of people in the vicinity, for example
people who use pacemakers and earphones for
hearing.
h) The daily duration of welding operations or other
activities.
The other devices must be electromagnetically com-
patible.This operation may require additional protec-
tive measures.
The dimensions of the area to be considered depend
on the structure of the building and the type of activ-
ity in progress.
PACEMAKERS AND HEARING AIDS
Magnetic fields deriving from high currents can af-
fect the correct functioning of pacemakers and hear-
ing aids. Wearers of electronic equipment should
consult a physician before approaching arc welding
operations.
METHODS FOR REDUCING EMISSIONS
A) Power supply
The welding or cutting device must be connected to
the power supply following the manufacturer's rec-
ommendations.
When interference problems arise, it may be neces-
sary to take measures to solve the problem, such as
the addition of filters on the power supply.
In the case of permanent installation of the equip-
ment, the metal shielding of the power cables can be
taken into consideration. The shielding must be con-
nected to the welding machine so that there is good
electrical contact between it and the mantle of the
welding machine itself.
B) Welding machine maintenance
The welding machine must be periodically subjected
to maintenance, according to the manufacturer's in-
structions.
Remove dust or foreign materials every 6 months,
which may have been deposited on the transformer
or on the diodes of the rectifier unit; to do this use a
jet of dry, clean air.
The mantle and all the possible accesses inside the
welding machine must be correctly closed during
the welding and cutting operations. The welding ma-
chine must never be modified in any part except for
modifications planned and authorised by the manu-
facturer and carried out by persons authorised by the
manufacturer.
In particular, the distance of the arc from the work
piece and the stabilisation devices must be adjusted
and maintained according to the manufacturer's rec-
ommendations.
1.995.202 EN - Rev. 1.1 13
NOVATIG 325 DC - NOVATIG 505 AC/DC
G.R.W.

•In explosive, corrosive atmospheres or with a high
concentration of dust or oily substances suspend-
ed in the air;
•In atmospheres with high fire risks;
•Exposed to adverse weather conditions;
•With safety devices bypassed or out of order;
•With electrical bridges and/or other means that
exclude power/parts of the machine.
3.4. HAZARDOUS AREAS
The work area pertaining to the operator which is
substantially the entire perimeter of the machine is
considered hazardous.
It is the responsibility of the operator to keep the
work area clear of persons or objects while using the
machine and to avoid damage to persons, things or
animals.
The use of the machine near other equipment or
machines introduces additional risks. The operator is
asked to evaluate these risks in order to prevent ac-
cidents.
3.5. SAFETY DEVICES
Welding machines are equipped with safety devices
designed to prevent damage to the operator or to the
welding machine itself. A safety device is any object
or system that can reduce the risk of such damage.
Do not tamper with active safety devices or their con-
nections.
Do not operate with the welding machine without
the metal covers or with non-insulated connections.
If necessary, during installation and connection, they
must be integrated with others in order to guarantee
compliance with the laws in force.
IMPORTANT: Daily check that the safety devices
are functioning properly and efficient.
The results of these checks must be reported on a
specific sheet.
ATTENTION: If worn or faulty parts are not prompt-
ly replaced, the manufacturer cannot be held in
any way liable for the damage caused by accidents
that may result.
If faults or anomalies are detected, they must be
eliminated before the machine is put into opera-
tion, and the expert carrying out the inspection
will have to certify that the repair has been made,
thus allowing the machine to be used.
If the person performing the inspection detects haz-
ardous faults, they must promptly inform the ma-
chine manufacturer.
Place the machine out of service if operating faults
are found while performing the appropriate checks/
inspections and/or repairs. Check that no objects
are left between the moving parts after any main-
tenance work.
In order to guarantee maximum safety of the ma-
chine it is, nonetheless, PROHIBITED to:
•Tamper with any part of the machine;
•Leave moving parts unattended;
•Use the machine when not operating at full effi-
ciency;
•Modify the machine to change the originally es-
tablished use, without explicit authorisation from
the Manufacturer;
•Run moving parts with manual operations in case
of power failure.
3.2. INTENDED USE
The system should only be used for the purpose for
which it was manufactured meaning to generate an
electrical arch for MIG/MAG, TIG, MMA welding or
plasma cutting accordingly.
ATTENTION: It cannot therefore be used as a de-
vice tor thaw pipes; any improper use automati-
cally voids the warranty and excludes the man-
ufacturer from any liability in case of damage to
persons and property.
3.3. CONTRAINDICATIONS FOR USE
The machine must not be used:

Before carrying out handling and lifting, check
the position of the centre of gravity of the load;
always check the correct weight balance of the
machine when it is transported, so as to prevent
unexpected machine movements or falls. It is
recommended to always use vehicles capable of
supporting the weight and dimensions of the ma-
chine ("TECHNICAL SPECIFICATIONS" paragraph
of this manual), so as to avoid damage to the ma-
chine or to persons or things around it.
IMPORTANT: the customer is always exclusively
liable during the equipment loading and unload-
ing phases.
For transport to the final installation site, it is prefera-
ble to use a forklift or pallet truck, taking care that the
lifting forks support the entire crate.
< 25 kg
For movements within the plant, the machine may be
transported with a crane by properly harnessing it us-
ing cables with the appropriate resistance character-
istics, depending on the weight of the machine itself.
If the supply includes only the welding machine,
generally weighing less than 25 kg, the packaging
consists of a cardboard box without lifting pallets. It
can be easily lifted by two operators and taken to the
place of use.
ATTENTION: The machine must remain packed
during unloading from the means of transport
and until it is transferred to its destination.

4.7. PREPARATIONS
Installation preparations
For the installation, it is necessary to prepare a ma-
noeuvring area suited to the machine dimensions
and selected lifting means. The machine must be
positioned so that it is ideally ergonomic and pro-
vides maximum safety in the work place: leave an
area around it large enough to allow easy operations
and handling of the material to be processed and for
maintenance and adjustment operations to be car-
ried out.
Before installing the machine, check that the selected
area is suitable and has the necessary authorisations
to carry out the activity, sufficiently ventilated and il-
luminated, with a stable and levelled support surface.
For installations on a raised floor, check that the slab
can withstand the load.
Electrical system preparation
Connection to the electrical system which powers and
combines the synchronisation with other machines
should be done by specialised and qualified staff fol-
lowing the wiring diagram and arrangements set out
If only the welding ma-
chine is present, this must
be handled using the
convenient handle on the
upper part of the welding
machine itself.
ATTENTION: risk of overturning when unloading
the machine from the pallet equipped with de-
scent ramps.
ATTENTION: when carrying out unpacking op-
erations, it may be necessary to have two per-
sons equipped with suitable personal protective
equipment.
IMPORTANT: in addition to handling the machine us-
ing the special trolley, it can be lifted from the ground
after having wrapped it with lifting straps, by slinging
it from the bottom in a stable and safe way. If provid-
ed, the machine must be lifted only and exclusive-
ly by using M10 eye-bolts which are not supplied.

4.9. CONNECTIONS
Electrical connections
The machine's internal connections are carried out
by qualified personnel sent by the manufacturer. The
electrical connection between the machine panel
and the customer's power distribution supply line
must be carried out by qualified personnel from the
Customer.
IMPORTANT: The personnel qualified to carry out
the electrical connection must make sure of the
perfect efficiency of the earthing of the electrical
system and must check that the line voltage and
the frequency correspond to the data shown on
the identification plate. Incorrect supply voltages
can cause serious damage to the system.
If the system is set to operate at single-phase 230 V at
50-60 Hz, wire the end of the power cable to an EEC
plug with the same capacity as the socket on the line
switch as per the following diagram:

ficient and separate from the rest of the electrical
system of the working environment.
in Laws and/or Technical Standards currently in force
for safety in workplaces and electrical installations.
Appropriate safety devices must be provided for its
operation in line with those required in the area of
safety in the workplace.
IMPORTANT: The manufacturer cannot held li-
able for any damage to property, persons and/
or animals caused by non-compliance with this
provision.
To achieve an adequate level of safety, the electri-
cal system to which the machine is connected must
provide, at the user's full charge, an earthing system
according to the provisions of the user's country, a
circuit breaker to protect the power supply socket
with value I (current variation) not less than 30mA
and anything else for a correct execution in a work-
manlike manner, according to Laws and/or Technical
standards in matters of safety in the workplace and
electrical systems. Prepare connections for earthing

sole liability of the user and nothing can be attrib-
uted to the manufacturer for damage to proper-
ty, persons and/or animals due to poor electrical
connections.
4.8. ASSEMBLY/POSITIONING
WARNING: the assembly of any detached units
and the installation of the machine must be car-
ried out exclusively by technicians authorised by
the manufacturer.
To allow for correct operations, the machine must
always be positioned in places that comply with the
environmental conditions described in this manual.
The machine must always be positioned in a perfect-
ly levelled area; levelling can also be carried out using
any adjustment systems present on the machine.
ATTENTION: The machine must be positioned so
as not to obstruct the entry and exit of the air
from the cooling slots. REDUCED FLOW OF AIR
causes overheating and possible damage to in-
ternal parts. Keep at least 500 mm of free space
around the device.
IMPORTANT: Do not place any filtering device on
the air intake passages of this welding machine.
The warranty is void if any type of filtering device
