3. SAFETY OF USE
ATTENTION! Read all safety warnings and all
instructions. Failure to follow the warnings and
0-60
instructions may result in an electric shock, fire and/
or serious injury or death.

3.1. GENERAL NOTES

• Take care of your own safety and the one of third
parties by reviewing and strictly following the
5-210
instructions, included in the operating manual of the
device.
0-20
• Only qualified and skilled personnel can be allowed
to start, operate, maintain and repair the machine.
• The machine must never be operated contrary to its
intended purpose.
3.2. PREPARATION OF WELDING WORK SITE
10-90
WELDING OPERATIONS
EXPLOSION!
• Strictly follow the occupational health and safety
regulations applicable to welding operations and
make sure to provide appropriate fire extinguishers
0,5-200
at the welding work site.
• Never carry out welding operations in flammable
10-180 places that pose the risk of material ignition.
• Never carry out welding operations in an atmosphere
YES (0-180)
containing flammable particles or vapours of
explosive substances.
YES (0,1-10)
• Remove all flammable materials within 12 meters
YES (0,01-1)
from the welding operations site and if removal is
not possible, cover the flammable materials with fire
1.6 – 5
retardant covering.
• Use safety measures against sparks and glowing
1.0 – 3.2
particles of metal.
HF • Make sure that sparks or hot metal splinters do
not penetrate through the slots or openings in the
F
coverings, shields or protective screens.
• Do not weld tanks or barrels that contain or have
≥85
contained flammable substances. Do not weld in the
0,75
vicinity of such containers and barrels.
• Do not weld pressure vessels, pipes of pressurised
IP21S
installations or pressure trays.
• Always ensure adequate ventilation.
6,4
• 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 colouring of the shield 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 operations site in order
to protect other people from the blinding light
radiation or projections.
• Always wear earplugs or another type of 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.
• Electrical arc and the working area are electrically
MAY CAUSE FIRE OR charged during the power flow.
• Input circuit and inner power circuit of the devices
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 that are
big enough as not to allow for body contact with an
object or the floor, must be placed on the floor.
• 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. Incorrect connection of 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 must not 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 fitting 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.
• The chassis ground must be mounted to the welded
element or as close to it as possible (e.g. to a work
table).
THE DEVICE CAN STILL BE UNDER VOLTAGE UPON
FEEDER DISCONNECTION!
