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.
• The increased risk of electric shock due to the weld-
er coming into contact with earth when using a Class
I welding power source whose housing is earthed by
its protective earth conductor.
Protective clothing
• During the work, the welder must be protected
against rays and burns by clothing over their entire
body and face protection.
• Gauntlets made of a suitable material (leather) must
be worn on both hands. They must be in perfect con-
dition.
• Suitable aprons must be worn to protect clothing
from flying sparks and burns. If the type of work re-
quires it, e.g. overhead welding, an overall and, if
necessary, head protection must be worn.
• The protective clothing and all accessories used
must correspond to the "Personal Protective Equip-
ment" directive.
Protection from rays and burns
• Advise of the danger to the eyes with a note saying "Cau-
tion, do not look into the flames!" at the place of work.
Workplaces must be shielded as much as possible so
that persons in the vicinity are protected. Unauthorised
persons must be kept away from the welding work
• The walls should not be light-coloured or glossy in
the immediate vicinity of fixed workplaces. Windows
must not allow rays through and be secured against
the reflection of rays at least up to head height, e.g.
using a suitable coat of paint.
EMC equipment classification
ply system. It can be difficult to ensure electromagnet-
ic compatibility in these areas, both due to conducted
and radiated high-frequency interferences.
Even if the welding device complies with the emission
limits in accordance with the standard, arc welding
equipment may still cause electromagnetic interfer-
ence in sensitive 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 following:
• 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 radiation,
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.
• Equipment and installations at risk from disruptive
radiation should be removed from the welding area
if possible or shielded.
