Potential hazards during
electric arc welding
There are a series of potential
hazards that can occur during
electric arc welding. It is there-
fore 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
device from the mains voltage
immediately.
If electrical contact voltages
occur, switch off the device
immediately and 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 (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 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 electric arc also emits UV
radiation. Without suitable
protection the invisible ultravi-
olet radiation can cause very
painful conjunctivitis which
is not apparent until several
hours later. Furthermore, UV
