ENGLISH
Long-term inhalation of welding gases may be
28
harmful to your health. Work with an exhaust system
or in well ventilated spaces. Avoid direct inhalation
of gases.
Contact with the hose bundle nozzle and the material
being processed may cause burns. Special welding
gloves to be worn at all times.
Let the hose bundle nozzle and the material being
processed cool down after being operated.
Long-term working with the appliance may damage
hearing. Hearing protection to be used at all times.
Welder may only be used on a flat surface and with a
properly secured gas bottle.
Make sure the welding smoke is exhausted or the
place of welding ventilated well.
Hot slag and sparks may cause fire or explosion. Never
use the appliance in a flammable environment.
Wood, sawdust, „varnishes", petrol, kerosine, natural
gas, acetylene, propane and similar flammable mate-
rials must be removed from the place of work and the
surrounding area or protected against sparks flying
away. To extinguish fire, a suitable fire extinguisher
must be made ready nearby.
No welding or cutting on closed vessels and pipes.
No welding or cutting on vessels and pipes if they are
open, containing materials able to explode due to
heat or moisture or able to cause other dangerous re-
actions. Never use the welder to defrost frozen pipes.
The gas bottle must necessarily be secured against
falling.The welder must never be lifted together
with the gas bottle. Special regulations apply to the
transport of gas bottles.
Handling of gas bottles
Make sure the gas bottles are used and stored in
rooms with sufficient air inlet and outlet.
A leaking gas bottle may reduce the share of oxygen
in the inhaled air and therefore represent a risk of
suffocation. Before use, make sure the gas bottle
contains gas designed for the work being done.
Gas bottles must always be safely fixed in a vertical
position on a wall support or on a specially manufac-
tured gas bottle cart.
The bottle with shielding gas and the fixed adjust-
ment gas current equipment must not be moved. The
gas bottle valve must be closed during transport.
Close the gas bottle valve after use.
Instructions for the installation and opera-
tion of an arc welding device to prevent
possible electromagnetic interference:
As the manufacturer, we recommend that the
following assessments and measures be carried
out by a qualified electrician.
General
The user is responsible for setting up and
operating the arc welding machines/cutting
equipment in accordance with the manufactur-
er's instructions. If electromagnetic interference
is detected, it is the responsibility of the user of
the arc welding machines/cutting equipment to
find a solution with the technical assistance of
the manufacturer. In some cases, the measure
needed may simply consist of earthing the
welding circuit (see note). In other cases, it may
include complete electromagnetic shielding of
the power source of the arc welding machine/
cutting equipment and the workpiece, com-
bined with input filters. In all cases, electromag-
netic interference must be reduced until it no
longer causes any disturbance.
Note
The approach taken to earthing the welding
circuit depends on the local safety regulations.
Changing the earthing to improve electromag-
netic compatibility may increase the risk of
accidents or damage to equipment
Assessing the surroundings
Before setting up the arc welding machines
and/or cutting equipment, the user must assess
possible electromagnetic problems in the sur-
roundings.
When doing so, the following factors must be
taken into account:
a) other mains cables, control cables, signal and
telecommunication cables above, below and
next to the arc welding machines and/or cutting
equipment;
b) Audio and television broadcast transmitters
and receivers;
c) Computers and other control devices;
d) Safety equipment, e.g. protection for com-
mercial facilities;
e) the health of persons nearby, e.g. those using
pacemakers and hearing aids;
f) Calibration and measurement equipment;
g) the resistance of other equipment in the
vicinity to interference. The user must ensure
that
other equipment used in the environment is
suitable for such a purpose. This may require
additional protective measures;
h) the time of day during which the welding, cut-
ting, or other activities must be carried out.
