STAMOS S-MMA-120B Manual De Instrucciones página 6

• Never carry out welding operations in flammable
places that pose the risk of material ignition.
• It is prohibited to weld in the presence of an
explosive mixture of combustible gases, vapours,
mists or dust with air.
• Remove all flammable materials within 12 meters
from the welding operations site and if removal is
not possible, cover flammable materials with fire
retardant covering.
• Use safety measures against sparks and glowing
metal particles.
• Make sure that sparks or hot metal splinters do
not penetrate through the slots or openings in the
coverings, shields or protective screens.
• Do not weld tanks or barrels that contain or have
contained flammable substances. Do not weld in the
vicinity of such containers and barrels.
• Do not weld pressure vessels, pipes of pressurised
installations or pressure trays.
• Always ensure adequate ventilation.
• It is recommended to take a stable position prior to
welding.
3.3. PERSONAL PROTECTION EQUIPMENT
ELECTRIC ARC RADIATION CAN CAUSE DAMAGE TO EYES
AND SKIN!
• When welding, wear clean, oil stain free protective
clothing made of non-flammable and nonconductive
materials (leather, thick cotton), leather gloves, high
boots and protective hood.
• Before welding remove all flammable or explosive
items, such as propane butane lighters or matches.
• Use facial protection (helmet or shield) and eye
protection, with a filter featuring a shade level
matching the sight of the welder and the welding
current. The safety standards suggest colouring
No. 9 (minimum No. 8) for each current below 300
A. A lower shield colouring can be used if the arc is
covered by the workpiece.
• Always use approved safety glasses with side
protection under the helmet or any other cover.
• Use guards for the welding operation sites in order
to protect other people from the blinding light
radiation or projections.
• Always wear earplugs or another hearing protection
to protect against excessive noise and to avoid
spatter entering the ears.
• Bystanders should be warned to not look at the arc.
3.4. PROTECTION AGAINST ELECTRIC SHOCK
ELECTRIC SHOCK CAN BE LETHAL!
• The power cable must be connected to the nearest
socket and placed in a practical and secure position.
Positioning the cable negligently in the room and on
a surface which was not checked must be avoided, as
it can lead to electrocution or fire.
• Touching electrically charged elements can cause
electrocution or serious burns.
• The electrical arc and the working area are electrically
charged during the power flow.
• The device's input circuit and inner power circuit are
also under voltage charge when the power supply is
turned on.
• The elements under the voltage charge must not be
touched.
• Dry, insulated gloves without any holes and
protective clothing must be worn at all times.
• Insulation mats or other insulation layers, big enough
as not to allow for body contact with an object or the
floor, must be placed on the floor.
EN
• The electrical arc must not be touched.
• Electrical power must be shut down prior to cleaning
or electrode replacement.
• It must be checked if the earthing cable is properly
connected or the pin is correctly connected to the
earthed socket. Incorrectly connecting the earthing
can cause life or health hazard.
• The power cables must be regularly checked for
damage or lack of insulation. Damaged cables must
be replaced. Negligent insulation repair can cause
death or serious injury.
• The device must be turned off when it is not in use.
• The cable mustn't be wrapped around the body.
• A welded object must be properly grounded.
• Only equipment in good condition can be used.
• Damaged device elements must be repaired or
replaced. Safety belts must be used when working at
height.
• All fittings and safety elements must be stored in one
place.
• From the moment of turning on the release, the
handle end must be kept away from the body.
• Attach the ground cable to the part being welded or
as close to it as possible (e.g. to the work table).
• Disabling the VRD function may increase the risk of
electric shock (applies to models that have the VRD
function).
THE DEVICE CAN STILL BE UNDER VOLTAGE UPON
FEEDER DISCONNECTION!
• The voltage in the input capacitor must be checked
upon turning off the device and disconnecting it
from the power source. One must make sure that the
voltage value is equal to zero. Otherwise, the device
elements must not be touched.
3.5. GASES AND FUMES
PLEASE NOTE! GAS MAY BE LETHAL OR DANGEROUS TO
HUMAN HEALTH!
• Always keep a certain distance from the gas outlet
• When welding, ensure good ventilation. Avoid
inhaling the gas.
• Chemical substances (lubricants, solvents) must be
removed from the surfaces of welded objects as they
burn and emit toxic smokes under the influence of
temperature.
• The welding of galvanised objects is permitted only
when efficient ventilation is provided with filtration
and access to fresh air. Zinc fumes are very toxic, an
intoxication symptom is the so-called zinc fever.
3.6. SECURITY GUIDELINES FOR WORK THAT CONSTITUTES
A FIRE HAZARD
Preparation of the building and premises for work that
constitutes a fire hazard:
• removal of all flammable materials and waste from
rooms and premises where work will be carried out;
• moving any flammable objects and non-flammable
objects in flammable packages away to a safe
distance;
• materials that cannot be removed must be secured
against e.g. welding spatter by covering them with
e.g. metal sheets, drywall, etc.;
• check if materials or flammable objects
surrounding rooms require protection;
• seal with non-flammable materials any openings in
installation, ventilation, etc. located near the place of
work;

• secure electric cables, gas or installation pipes
covered with flammable insulation against welding
spatter if they are within the range of work that
constitutes a fire hazard;
• check that the planned work will not be carried
out in rooms that were painted using flammable
substances or where other flammable substances
were used on the day of planned work.
SPARKS MAY CAUSE A FIRE
Sparks produced by welding can cause fires, explosions
and burns on exposed skin. During welding, it is necessary
to wear welding gloves and protective clothing. Remove or
secure any flammable materials and substances from the
place of work. Do not weld sealed containers or tanks in
which flammable liquids were stored. Such containers or
tanks must be rinsed before welding to remove flammable
liquids. Do not weld in the vicinity of flammable gas,
vapours or liquids. Fire equipment (blankets, dry powder
extinguisher or extinguishing foam) must be placed near
the workplace in an easily visible and reachable place.
A CYLINDER MAY EXPLODE
Use only approved gas cylinders and a properly working
reducer. The cylinder should be transported, stored and
placed in a vertical position. Protect the cylinders from heat
sources, tipping over and mechanical damage. Maintain all
gas installation elements: cylinder, hose, fittings, reducer in
good condition.
WELDED MATERIALS CAN CAUSE BURNS
Never touch the welded components with parts of your
body without protection. When touching and moving
welded material, always use welding gloves and tongs.

4.3.CONNECTING THE DEVICE
4.3.1. CONNECTING THE POWER
• The connection of the device must be performer
by a qualified person. In addition, a person with
required qualifications should check if the earthing
or electrical installation with protection system is in
line with the safety regulations and if they operate
correctly.
• The device must be placed near the work station.
• Connecting excessively long conduits to the machine
must be avoided.
• One-phase welders should be connected to the
socket fitted with an earthing prong.
• Welders powered from a 3-Phase network are
delivered without a plug, the plug must be obtained
independently and installation should be assigned to
a qualified person.
PLEASE NOTE! THE DEVICE MAY ONLY BE USED
UPON CONNECTION TO AN INSTALLMENT WITH A
PROPERLY FUNCTIONING FUSE.
4.3.2. CONNECTING GAS
• Gas tanks must be placed far from the welded object
and be protected against falling.
• Gas connector of the welder must be connected with
the tank or gas installation by means of the correct
pipe and regulator with gas flow regulation.
Please note! Connection of line regulators to the
tank and the other way round is prohibited. Such a
change can result in regulator damage and serious
injuries.
• Economical gas use extends the welding time.
