11.5 Danger from shielding-gas cylinder
Shielding-gas cylinders contain pressurized gas and may explode if they are dam-
aged. As shielding-gas cylinders are an integral part of the overall welding outfit,
they also have to be treated with great care.
Protect shielding-gas cylinders containing compressed gas from excessive heat,
mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding-gas cylinders in the vertical and fasten them in such away that
they cannot fall over (i.e. as shown in the instruction manual).
Keep shielding-gas cylinders well away from welding circuits (and, indeed, from
any other electrical circuits).
Never hang a welding torch on a shielding-gas cylinder.
Never touch a shielding-gas cylinder with a welding electrode.
accessories.
11.6 EMC and safety inspection
Apart from the instructions given in this operating manual, the general safety standards, in particular the
rules for prevention of accidents must be observed. The rules contain additional information's about the pre-
vention of radiation, smoke, combustion, electric shock, fire and explosion.
The rules are:
BGV A3 (electrical installations and operating supplies) and
BGR 500 chap. 2-26 (welding, cutting and related working processes).
Furthermore, we point out that in some operative ranges where, despite the observance of radiation limits,
this welding unit can cause electromagnetic interferences which are the responsibility of the user.
This means that in the domain of hospitals, for instance, the function of electromedical units, data-processing
equipment and the like (ECG, PC etc.) may be impaired.
Before putting the welding unit into service, please make sure to inform the authorities in charge of the above
mentioned equipment.
If you wish to use the cutting unit in domestic areas, special precautions have to be taken as well.
Adequate assistance in assessing the operative range and minimizing electromagnetic interferences (e.g.
use of screening lines) may be obtained from the Electromagnetic Compatibility Standards for Arc Welding
Systems.
EN 60 974-10 (Electromagnetic compatibility EMC)
Safety inspection:
The owner/operator is obliged to have a safety inspection performed on the
machine at least once every 12 months.
Observe the relevant national and international standards and directives in
connection with the safety inspection.
More detailed information on safety inspections and calibration is available
from your regional or national service centre, who will be pleased to provide
you with copies of the necessary documents upon request
e.g.: EN 60974-4 (Safety, maintenance and inspection of arc welding equipment in use)
