Safety clothing
1. While working, the welder must protect his entire
body from radiation and burns by wearing
suitable clothing and a face guard.
2. Slip-on gloves made of a suitable material
(leather) must be worn on both hands. They
must be in perfect condition.
3. Suitable aprons must be worn to protect clothing
from sparks and burns. A safety suit and, if
necessary, head protection must be worn if
required by the type of work in question, e.g.
overhead welding.
Protection from radiation and burns
1. 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. Unauthorized persons are to be kept
away from the welding work.
2. The walls in the immediate vicinity of stationary
workplaces should not have a light color or a
sheen. Windows up to head height are to be
protected against radiation passing through them
or reflecting off them, for example by coating
them with a suitable paint.

5. Welding preparations
Connect the earth terminal (2) direct to the part to be
welded or to the support on which the part is resting.
Ensure that the earth terminal is in direct contact with
the part to be welded. You should therefore avoid
coated surfaces and/or insulated materials. The
electrode holder cable has a special clamp at one
end, which is used to secure the electrode. The
welding safety shield must be used at all times for
welding. It protects your eyes from the radiation
emitted by the arc and nevertheless enables you to
watch the welding process.
