PERSONAL PROTECTION

• Workers and their assistants must protect
themselves by wearing closed, non-flamma-
ble protection coveralls, without pockets or
rolled sleeves or legs. Any residue of oil or
grease must be cleaned from the garments
before wearing them. Only wear CE marked
garments suitable for arc welding and cutting
(Fig. 1):
1. Gloves;
2. Apron or jacket made of crust leather;
3. Gaiters to protect the shoes and the bottoms
of the trousers;
4. Protection shoes with steel toes and rubber soles;
5. Mask (please consult the paragraph on light
radiations);
6. Crust leather sleeves to protect the arms.
Figure 1
Caution: Make sure all protection gar-
ments are in good conditions and replace
them regularly in order to ensure perfect
personal protection.

LIGHT RADIATIONS

Warning: Never stare at an electric arc wi-
thout suitable eye protection (Fig. 2).
Figure 2
According to the requirements in 2006/25/
EC Directive and EN 12198 Standard, the
equipment is a category 2. It makes com-

pulsory the adoption of Personal Protective
(EN 12198)
Equipment (PPE) having filter with a pro-
tection degree up to a maximum of 15, as
required by EN169 Standard.
• Users must wear fireproof helmet or mask,
designed in such a manner as to offer protec-
tion to the neck and face (including the sides)
against the light of the electric arc (glare from
the visible light and infrared and ultraviolet
radiations). The helmet or the mask must be
equipped with a protector whose degree of
opacity will depend on the welding or cutting
procedure and on the value of the electric arc
current, according to the values contained in
Table 1 (EN 169).

Table 1
• The colored filter (inactinic filter) must be kept
clean at all times. Should it break or dete-
riorate (Fig. 3), replace it with a new filter,
with the same degree of opacity. The colored
filter must be protected against impact and
welding or cutting projections by means of a
transparent glass positioned on the anterior
part of the mask. This transparent glass must
be replaced whenever visibility is reduced du-
ring welding.

WORKING AREA

Welding or cutting operations must be carried out
in a sufficiently ventilated place, isolated from other
working areas. If this is not possible, anyone near
the person operating the welding machine and
their assistants must be protected by curtains and
