Arc welding and plasma cutting are processes
that can pose hazards for the operator and
persons in his vicinity. The operator and
his close surroundings are exposed, among
others, to the risk of re, explosion, electric
shock, burning, as well as the risk of getting
injured by moving parts of the device.
Once proper safety measures are provided,
electric welding and plasma cutting are
relatively safe processes. For this reason,
it is crucial to strictly follow the valid OSH
principles during welding operations.
The information provided below does not
release the operator from the obligation to
follow the OSH rules that are binding in his
plant/workplace.
1.1. GENERAL SAFETY RULES
Welding operators and persons working in the
vicinity of the welding process should be made
aware of the following hazards associated
with arc welding. They should be made aware
of protective measures as specied in relevant
international and national standards and
regulations.

components of the device.
• Power supply must never be connected
before the accessories of DINSE sockets/
connectors are properly installed in the
device.
• Use dry and undamaged welding gloves
and protective clothing, in order to
ensure proper insulation of the body. It is
forbidden to touch with a bare hand any
elements that are parts of an electric circuit.
• The operator must always make sure that
there is a good electric connection of the
return conductor to the element to be
welded. The connection should be located
as close to the welding zone as possible.
• Maintain the electrode grip, the welding
torch, the chassis ground clamp, welding
cables and the welding machine in proper
technical condition that ensures safe
operation. Damaged cable insulation
should be replaced with new insulation.
• Never dip an electrode into water, to cool
it down.
• When working above the oor level (at
a height), use a safety harness to protect
yourself against falling, in the case of
potential electric shock.
• Exercise special caution, when using the
device in small rooms or in rooms with
elevated humidity levels.
1.3. WELDING ARC RADIATION CAN BE
DANGEROUS
The arc generates:
• ultraviolet radiation (can damage skin and
eyes);
• visible light (can dazzle eyes and impair
vision);
• infrared (heat) radiation (can damage skin
and eyes).
Such radiation can be direct or reected
from surfaces such as bright metals and light
coloured objects.
1.3.1. EYE AND FACE PROTECTION
• Use welder’s helmet/shield with an
appropriate lter to protect you face
and eyes against sparks and welding arc
radiation.
• Welding helmet/shield should prevent
injuries from ying particles, e.g. slag,
fragments from grinding or wire bristles,
etc.
• Welding helmet/shield should be made in
accordance with applicable standards.
1.3.2. BODY PROTECTION
• The body should be protected by suitable
clothing in accordance with applicable
standards.
• Use appropriate protective clothing made
of durable and re-resistant material, to
ensure proper skin protection.
• The use of neck protection can be
necessary against reected radiation.
1.3.3. PROTECTION OF PERSONS IN THE
VICINITY OF AN ARC
• Protect the remaining personnel present
in the vicinity of welding works against
negative impact of arc radiation and
welding splatters. Warn them about the
hazard resulting from exposure to the
welding arc.
• In the vicinity of an arc, non-reective
curtains or screens should be used to
isolate persons from the arc radiation. A
warning, e.g. a symbol for eye protection,
should refer to the hazard of arc optical
radiation.
• Welder’s assistants should also wear
appropriate protective clothing.

1.4. VAPOURS AND GASES CAN BE
DANGEROUS
Arc welding and allied processes produce
welding fume which may pollute the
atmosphere surrounding the work. Welding
fume is a varying mixture of airborne gases and
ne particles which, if inhaled or swallowed,
constitute a health hazard.
The degree of risk is depend on:
• the composition of the fume;
• the concentration of the fume;
• the duration of exposure.
A systematic approach to the assessment of
exposure is necessary, taking into account the
particular circumstances of the operator and
the ancillary worker who can be exposed.
Welding fume may be controlled by a wide
range of measures, e.g. process modications,
engineering controls, methods of work,
personal protection and administrative action.
First it is necessary to consider whether
exposure can be prevented by eliminating the
generation of welding fume altogether. Where
this cannot be done, measures for reducing
the quantity of welding fume generated
should be investigated, after which the
control of welding fume at source should be
considered. The use of respiratory equipment
should not be contemplated until all other
possibilities have been eliminated. Normally,
respiratory protective equipment should be
used only as an interim measure. There will,
however, be circumstances where, in addition
to ventilation measures, the use of personal
protection can be necessary.
1.4.1. VAPOURS AND GASES. ADDITIONAL
PRECAUTIONS
• Welding operations can involve generation
of vapours and gases that are hazardous
to health. Inhaling the vapours should
be avoided. Keep your head away from
vapours during welding operations. Ensure
proper ventilation and/or mechanical
welding exhaust draught to keep vapours
and gases away from the breathing zone.
• When welding is carried out in a conned
space, operators should only be permitted
to weld when other persons, who have been
instructed and who are able to react in case
of an emergency, are in the immediate
vicinity.
• In closed rooms or in certain circumstances
during outdoor operations, it may be
required to use individual equipment for
the protection of the welder’s airways, e.g.
a respirator. Additional safety measures
are also required when galvanized steel is
welded.
• Welding operations must not be performed
in the vicinity of chlorinated hydrocarbons
generated during degreasing, cleaning or
spraying operations. Heat and radiation
generated by the arc may enter into a
reaction with vapours of solvents, which
may lead to the formation of phosgene – a
highly toxic gas..
• The shielding gas used during arc welding
may force the air out of a room. This may
lead to a health hazard or even death.
Proper ventilation, especially in closed
rooms, should always be provided, to
ensure appropriate amount of air that is
indispensable for safe breathing.
1.5. NOISE CAN BE HARMFUL
In the welding environment, damaging levels
of noise can exist. Continued exposure to
a high noise level on the unprotected ear is
injurious. The noise levels should be reduced
to the lowest practicable level.
High levels may be tolerated for very short
periods of time by wearing adequate ear
protection in accordance with the national or
local regulation.
4
SPARTUS Easy TIG * USER’S MANUAL
ENG

In case of doubt, checks by an expert should
be made to establish noise levels in any
particular environment, and, if these are
in excess of the prescribed limit, one of the
following alternatives may apply:
a) Insulation of the noise source as far as
possible, e.g. by tting silencers or sound
proof enclosures
b) Insulation of the operator from the noise
source
c) Effective maintenance of sound protection
devices
d) Indication as „ear protection areas” where
applicable
e) Restriction of entry to these „ear protection
areas” to authorized persons.
f) Protect your hearing with appropriate
personal protection measures, e.g. earplugs
or hearing protectors.
1.6. FIRE AND EXPLOSION
Arc welding and allied processes can cause
re and explosions and precautions should
be taken to prevent these hazards.
1.6.1. FIRE
• Before setting to perform welding
operations, ensure that elements involving
re hazard are removed from the zone
where welding operations are to be
performed. If this is impossible, protect
all ammable elements against the impact
of sparks. Remember that sparks and hot
metal may penetrate through small cracks
and openings into the adjacent area.
• Avoid welding in the vicinity of hydraulic
conduits.
• The welding arc throws sparks and splatters
out. Welders should wear clean and dry
protective clothing (staining with oil should
be avoided in particular) such as welding
gloves, welder’s apron, welder’s trousers,
welder’s boots, protective hood/cap, etc.
• When no welding operations are carried
out, make sure no part of the electrode is
in contact with the material to be welded
or chassis ground. Accidental contact may
lead to overheating and create a re hazard.
• An extinguisher should always be ready
for use and available in an easily accessible
place nearby.
• The surroundings of the work should be
observed for an adequate period after its
termination.
• „Hot spots” and their immediate
surroundings should be observed until
their temperature has dropped to normal.
1.6.2. EXPLOSION
• It is forbidden to heat up, cut or weld tanks,
barrels or containers that contained toxic
or ammable materials. For there is an
explosion hazard, even if the containers
have been emptied and cleaned.
1.6.3. USE OF CYLINDERS WITH SHIELDING
GAS
• In case compressed gases are used in the
work place, apply special safety measures
to prevent dangerous situations.
• Use gas cylinders with appropriate
shielding gas, foreseen for a particular
process. Additional equipment (pressure
regulator, hoses, connectors) should be in
good technical condition. A gas cylinder
and accessories should have the required
valid attestations and approvals for use.
• Gas cylinders should always be stored in
vertical position, xed to an undercarriage
or permanent support.
• Gas cylinders should be placed far away
from areas, where they could be exposed
to the risk of being overthrown or suffering
physical damage.
5
SPARTUS Easy TIG * USER’S MANUAL
ENG

• Ensure gas cylinders are at a safe distance
from places where electric welding or
cutting operations are to be performed,
away from other sources of heat, sparks or
ames.
• Care shall be taken to prevent gas cylinders
in the vicinity of the workpiece becoming
part of the welding circuit.
• Never allow the electrode, electrode holder
or any other live electric part to get in
contact with the gas cylinder.
• Keep your face and head away from the
cylinder valve socket when the valve is
being opened.
• Special valve shield should always be
installed during cylinder transportation or
when the cylinder is not used.
1.7. OTHER HAZARDS
Arc welding and allied processes carrying
other hazards not listed before.
1.7.1. HOT PARTS CAN CAUSE BURNS
• Never touch hot parts with bare hands.
• Before handling an element, wait until it
cools down.
• Use appropriate tools to grip and handle
hot elements and wear special welding
gloves and clothing that protects against
burns.
1.7.2. PLASMA ARC IS DANGEROUS
• Highly concentrated plasma arc poses
a hazard for health and life. It is
forbidden to aim plasma arc at people.
1.7.3. WELDING WIRE CAN CAUSE INJURIES
• Accidental pressing of the button on the
welding torch can cause welding wire to
advance in an uncontrolled manner. The
welding wire tip may be sharp.
• Never aim the burner tip of the welding
torch at your face, eyes or other people.
1.7.4. MOVING ELEMENTS CAN BE
DANGEROUS
• All protective elements and device housing
should be in place and in good technical
condition. Keep your hands, hair, clothes and
tools away from gear wheels, fans and other
moving parts during their operation.
• Do not bring your hands close to
fan motors. It is forbidden to try
to stop a fan by pressing its axle.
1.7.5. HF – HIGH FREQUENCY IGNITION MAY
CAUSE INTERFERENCE
• As welding by the TIG method or plasma
cutting involves high frequency ignition, it can
interfere with mobile phones, radio equipment,
TV equipment or improperly protected
computers and industrial robots, which leads
to total disabling of such devices.

7.7.5. COURSE OF TIG WELDING PROCESS - 4T
During TIG 4T, it is possible to preset the current value of the initial and nal current.
With this feature, you can prevent ooding at the beginning of the weld and ll the
crater formed at the end of the weld.
0Press and hold the gun switch, Electromagnetic gas valve is turned on. The
shielding gas stars to ow.
0 – 1 Pre-gas time.
1 Initiation of the welding arc.
1 – 2 The rise time of the welding current.
2 Loosen the gun switch, the output current slopes up from the start current.
2 – 3 The output current rises to the setting value (Iw or Ib), the upslope time can
be adjusted.
3 Achieving the set value of welding current.
3 – 4 Welding process. During this period, the gun switch is loosen.
4Press the torch switch again, the welding current will drop in accordance
with the selected down-slope time.
4 – 5 The output current slopes down to the crater current. The downslope time
can be adjusted.
5 Achieving the desired current end.
5 – 6 The crater current time.
6Loosen the gun switch, stop arc and keep on argon owing.
6-7 Post-gas time.
7Electromagnetic valve is closed and stop argon owing. Welding is
nished.

8. MAINTENANCE
WARNING: Before performing any maintenance or repairing of device,
disconnect welder from the power source and wait at least 5 minutes. The voltage
accumulated in capacitors should be discharged at this time to a safe level. But
even after that operation you should be careful.
Maintenance and repair work may be performed only by qualied
personnel with the appropriate permissions. Regular maintenance
provides adequate service life and trouble-free operation of the device.
Routine maintenance (Daily: before use/installation):
• Perform a visual inspection of the housing, knobs, control panel.
• Inspect (visual inspection) the power cord and power plug. Check the insulation of the
cable.
• Check the condition of welding cables and their connectors. If cable insulation is da-
maged - replace it. If connection is too loose - eliminate backlash.
• Check if cooling fan is working properly
• Make sure that all vents are not obstructed.
At least once a month:
• Regularly remove dust from inside of the machine. Use for this compressed air. The
pressure should be sufciently low so as not to damage small components inside the
machine. If in the workplace, dust levels are high. You should clean machine often.
• Perform inspection of connection of internal electrical components. If anywhere the
joints are loose, tighten them.
