Potential hazards during
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.
z
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.
z
In the event of accidents,
disconnect the welding
devoice from the mains voltage
immediately.
z
If electrical contact voltages
occur, switch off the device
immediately and make sure you
have it checked by a qualified
electrician.
z
Always ensure good electrical
contacts on the welding current
side.
z
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.
z
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.
z
Wear suitable protective cloth-
ing, no synthetic garments.
z
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.
z
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.
