Scheppach WSE3200 Original Bedienungsanleitung Seite 23

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 cur-
rent 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 supply-
ing all mains operated equipment in the vicinity. The
fault-circuit interrupter must be suitable for all types
of current.
Means for rapid electrical disconnection of the weld-
ing current source or welding current circuit (e.g.
emergency stop device) shall within easy reach.
When welding equipment is used in electrically haz-
ardous 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
persons who can intervene if necessary, are in the
immediate vicinity. Here, an assessment by an expert
must be carried out before the welding process begins
to determine 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 opera-
tion 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
power source is worn, e.g. with a shoulder sling.
This is to prevent:
• The risk of losing balance when pulling connected
cables or hoses.
• The increased risk of electric shock due to the
welder coming into contact with earth when using
a Class I welding power source whose housing is
earthed by its protective earth conductor.
Safety clothing
• While working, the welder must protect his entire
body from radiation and burns by wearing suitable
clothing and a face guard.
• Slip-on gloves made of a suitable material (leather)
must be worn on both hands. They must be in per-
fect condition.
• Suitable aprons must be worn to protect clothing
from sparks and burns. A safety suit and, if neces-
sary, head protection must be worn if required by
the type of work in question, e.g. overhead welding.
• The protective clothing used as well as all acces-
sories must be in compliance 89/686/EWG with the
"Personal safety equipment" EU Directive.
Protection from radiation and burns
• Provide information about the risk to eyes at the
working site in the form of a poster with the wording
"Caution – do not look at the flames". Workplaces
are to be screened off wherever possible so that
personnel in the vicinity are protected. Unauthor-
ized persons are to be kept away from the welding
work.
• The walls in the immediate vicinity of station-
ary workplaces should not have a light color or a
sheen. Windows up to head height are to be pro-
tected against radiation passing through them or
reflecting off them, for example by coating them
with a suitable paint.
• Flying welding sparks can cause painful burns and
so the following instructions must be observed:
- Always wear a protective leather apron
- Always wear leather gloves
- Wear suitable headgear for overhead welding
work
- Always wear sturdy and insulated footwear
EMV device classification
It can be difficult to ensure electromagnetic compat-
ibility in these areas, both due to conducted and radi-
ated high-frequency interferences.
Even if the welding device complies with the emission
limit values of the standard, arc welding devices can
still result in electromagnetic interferences in sensi-
tive systems and devices. The user is responsible for
interference caused by the arc during welding and the
user must take appropriate protective measures.
The user must pay particular attention to the fol-
lowing:
• Mains, control, signal and telecommunication lines
• Computers and other microprocessor-controlled
devices
• Television, radio and other playback equipment
• Electronic and electrical safety devices
• Persons with pacemakers or hearing aids
• Measuring and calibration equipment
• Immunity of other equipment in the vicinity
• The time of day when the welding work is carried
out.
In order to reduce possible interference radia-
tion, it is recommended:
• Set up and operate the welding device properly to
minimise possible disruptive emissions.
• Maintain the welding device regularly and keep it in
good condition.
• Welding cables should be fully unwound and run
parallel to the floor insofar as possible

intended for use in residential environ-
ments in which the power supply comes
from a public low-voltage supply system.
