Potential hazards during
z
electric arc welding
There are a series of potential
hazards that can occur during
electric arc welding. It is therefore
particularly important for the
welder to observe the following
rules to avoid endangering him/
herself and others and to prevent
damage to people and the
device.
Work on the voltage side,
e.g. on cables, plugs, sockets
etc., may only be carried
out by qualified electricians
according to national and local
regulations.
In the event of accidents,
disconnect the welding
devoice from the mains voltage
immediately.
If electrical contact voltages
occur, switch off the device
immediately and make sure you
have it checked by a qualified
electrician.
Always ensure good electrical
contacts on the welding current
side.
Always wear insulating gloves
on both hands during welding
work. These provide protection
from electrical shocks (open
circuit voltage of the welding
current circuit), harmful radia-
tions (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 fall-
ing incandescent metal droplets
can cause burns.
Wear suitable protective cloth-
ing, no synthetic garments.
Do not look into the electric 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 elec-
tric arc also emits UV radiation.
Without suitable protection the
invisible ultraviolet radiation
can cause very painful conjunc-
tivitis which is not apparent
until several hours later.
Furthermore, UV radiation can
cause burns with sunburn-like
effects on unprotected parts of
the body.
Any persons in the vicinity of
the electric arc or helpers must
also be informed of the dangers
and be equipped with the
necessary protective equipment.
