Danger due to welding sparks
Welding sparks can cause an explosion or fire. Keep
flammable materials away from welding. Do not weld
next to flammable materials. Welding sparks can cause
fires. Keep a fire extinguisher nearby and an observer
who can use it immediately. Do not weld on drums or
any closed containers.
Safety instructions specific to welding masks
• Always make sure that the welding mask is func-
tioning properly by using a bright light source (e.g.
lighter) before starting welding work.
• Welding spatter can damage the protective panel.
Replace damaged or scratched protective panels
immediately.
• Replace damaged or heavily soiled or splattered
components immediately.
• The device must only be operated by people over
the age of 16.
• Familiarise yourself with the safety instructions for
welding. Also observe the safety instructions for
your welding device.
• Always put on the welding mask when welding. Fail-
ure to do so may result in serious retinal injuries.
• Always wear protective clothing when welding.
• Never use the welding mask without a protective
panel.
• Replace the protective panel in good time for good
visibility and fatigue-free working.
Environment with increased electrical hazards
When welding in environments with increased electri-
cal hazards, the following safety instructions must be
observed.
Environments with increased electrical hazards can be
found, for example:
• At workplaces where the range of movement is re-
stricted so that the welder works in an enforced pos-
ture (e.g. kneeling, sitting, lying down) and touches
electrically conductive parts;
• At workplaces which are wholly or partially bounded
by electrically conductive parts and where there is
a high risk of avoidable or accidental contact by the
welder;
• In wet, humid or hot workplaces where humidity or
perspiration significantly reduces the resistance of
human skin and the insulating properties or protec-
tive equipment.
A metal ladder or scaffolding can also create an envi-
ronment with increased electrical hazards.
In such environments, use insulated pads and shims.
Also, gauntlet-style gloves and headgear made of
leather or other insulating material should be worn to
insulate the body from earth. The welding power source
must be located outside the work area or electrically
conductive surfaces and out of reach of the welder.
Additional protection against shock from mains current
in the event of a fault may be provided by the use of a
residual current circuit breaker operating at a leakage
current not exceeding 30 mA and supplying all mains
operated equipment in the vicinity. The fault-circuit in-
terrupter must be suitable for all types of current.
Means for rapid electrical disconnection of the welding
current source or welding current circuit (e.g. emergen-
cy stop device) shall within easy reach. When welding
equipment is used in electrically hazardous conditions,
the output voltage of the welding equipment shall not
exceed 113 V (peak value) under no-load conditions.
This welding equipment may be used in these cases
because of the output voltage.
Welding in confined spaces
When welding in confined spaces, there may be a risk
of toxic gases (danger of suffocation). Welding may
only be carried out in confined spaces if instructed per-
sons who can intervene if necessary, are in the imme-
diate vicinity. Here, an assessment by an expert must
be carried out before the welding process begins to de-
termine which steps are necessary to ensure the safety
of the work and which precautionary measures should
be taken during the actual welding process.
Summation of open circuit voltages
If more than one welding power source is in operation
at the same time, their open-circuit voltages can add
up and lead to an increased electrical hazard. Welding
power sources must be connected in such a way that
this hazard is minimised. The individual welding power
sources, with their separate controls and connections,
must be clearly marked to indicate what belongs to
which welding circuit.
Use of shoulder slings
Welding shall not be carried out while the welding pow-
er source is worn, e.g. with a shoulder sling.
This is to prevent:
• The risk of losing balance when pulling connected
cables or hoses.
