work. These provide protection
from electrical shocks (no-load
voltage of the welding current
circuit), harmful radiations
(heat and UV radiation)
and incandescent metal and
splashes of slag.
Wear sturdy, insulating shoes.
The shoes should also insulate
when exposed to moisture.
Loafers are not suitable as
falling incandescent metal
droplets can cause burns.
Wear suitable protective cloth-
ing, no synthetic garments.
Do not look into the arc
without eye protection; only
use a welding mask with the
prescribed protective glass as
per DIN. In addition to light
and heat radiation, which can
dazzle or cause burns, the
arc also emits UV radiation.
Without suitable protection the
invisible ultraviolet radiation
can cause very painful con-
junctivitis which is not appar-
ent until several hours later.
Furthermore, UV radiation can
cause sunburn-like effects on
unprotected parts of the body.
Any persons in the vicinity of
the arc or helpers must also be
informed of the dangers and be
equipped with the necessary
protective equipment. If neces-
sary, set up protective walls.
Ensure an adequate supply
of fresh air whilst welding,
particularly in small spaces, as
it produces smoke and harmful
gases.
No welding work may be
carried out on containers that
have been used for storing
gases, fuels, mineral oils or
similar – even if they have
been empty for a long time –
as possible residues may
present a risk of explosion.
Special regulations apply in
rooms where there is a risk of
fire or explosion.
Welded joints that are subject
to heavy stress loads and are
required to comply with certain
safety requirements may only be
carried out by specially trained
and certified welders. Examples
of this are pressure vessels,
running rails, tow bars, etc.
ATTENTION!
Always connect
the earth terminal as close as
possible to the point of weld to
provide the shortest possible
path for the welding current
from the electrode to the earth
terminal. Never connect the
earth terminal to the housing of
the welder! Never connect the
