PERSONAL PROTECTION

• Workers and their assistants must protect
themselves by wearing closed, non-fl amma-
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 (Fig. 1):
1. Gloves;
2. Apron or jacket
made of crust lea-
ther;
3. Gaiters to protect
the shoes and the
bottoms of the trou-
sers;
4. Protection shoes
with steel toes and
rubber soles;
5. Mask (please con-
sult the paragraph
on light radiations);
6. Crust leather slee-
ves to protect the
arms.
Caution: Make sure all protection
garments are in good conditions
and replace them regularly in or-
der to ensure perfect personal
protection.

LIGHT RADIATIONS

• Warning: Never stare at an electric arc wi-
thout suitable eye protection (Fig. 2).
• Users must wear fi reproof 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 procedure
and on the value of the electric arc current,
according to the values contained in Table 1
(EN 169).

• The colored fi lter (inactinic fi lter) must be
kept clean at all times. Should it break or dete-
riorate (Fig. 3), replace it with a new fi lter, with
the same degree of opacity. The colored fi lter
must be protected against impact and welding
projections by means of a transparent glass
positioned on the anterior part of the mask.
This transparent glass must be replaced whe-
never visibility is reduced during welding.

WORKING AREA

Welding or cutting operations must be carri-
ed out in a suffi ciently ventilated place, iso-
lated 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 transpa-
rent opaque screens, self-extinguishable and
in accordance with regulation EN 1598 (the
