Longterm inhalation o welding gases may be
28
harmul to your health. Work with an exhaust system
or in well ventilated spaces. Avoid direct inhalation
o 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 ater 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 at surace and with a
properly secured gas bottle.
Make sure the welding smoke is exhausted or the
place o welding ventilated well.
Hot slag and sparks may cause re or explosion. Never
use the appliance in a ammable environment.
Wood, sawdust, „varnishes", petrol, kerosine, natural
gas, acetylene, propane and similar ammable mate
rials must be removed rom the place o work and the
surrounding area or protected against sparks ying
away. To extinguish re, a suitable re extinguisher
must be made ready nearby.
No welding or cutting on closed vessels and pipes.
No welding or cutting on vessels and pipes i 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 derost rozen pipes.
The gas bottle must necessarily be secured against
alling.The welder must never be lited together
with the gas bottle. Special regulations apply to the
transport o gas bottles.
Handling of gas bottles
Make sure the gas bottles are used and stored in
rooms with sufcient air inlet and outlet.
A leaking gas bottle may reduce the share o oxygen
in the inhaled air and thereore represent a risk o
suocation. Beore use, make sure the gas bottle
contains gas designed or the work being done.
Gas bottles must always be saely xed in a vertical
position on a wall support or on a specially manuac
tured gas bottle cart.
The bottle with shielding gas and the xed adjust
ment gas current equipment must not be moved. The
gas bottle valve must be closed during transport.
Close the gas bottle valve ater 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 qualied 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. I electromagnetic intererence
is detected, it is the responsibility of the user of
the arc welding machines/cutting equipment to
nd a solution with the technical assistance o
the manuacturer. 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 lters. 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 saety 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) Saety equipment, e.g. protection or com-
mercial facilities;
e) the health o 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 intererence. The user must ensure
that
other equipment used in the environment is
suitable or 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.
