ENGLISH
Electromagnetic emissions and the radiation of electromagnetic disturbances
This welding equipment for industrial and professional use is in
conformity with the European Standard EN50199. The purpose of
this standard is to prevent the occurrence of situations where the
equipment is disturbed or is itself the source of disturbance in other
electrical equipment or appliances. The arc radiates disturbances,
and therefore, a trouble-free performance without disturbances or
disruption, requires that certain measures are taken when installing
and using the welding equipment.
The user must ensure that the
operation of the machine does not occasion disturbances of
the above mentioned nature.
The following shall be taken into account in the surrounding area:
1.
Supply and signalling cables in the welding area which are
connected to other electrical equipment.
2. Radio or television transmitters and receivers.
3. Computers and any electrical control equipment.
4. Critical safety equipment e.g. electrically or electronically con-
trolled guards or protective systems.
5. Users of pacemakers and hearing aids etc.
6. Equipment used for calibration and measurement.
7. The time of day that welding and other activities are to be
carried out.
8. The structure and use of buildings.
If the welding equipment is used in a domestic establishment it
may be necessary to take special and additional precautions in
order to prevent problems of emission (e.g. information of tem-
porary welding work).
Methods of reducing electromagnetic emissions:
1.
Avoid using equipment which is able to be disturbed.
2. Use short welding cables.
3. Place the positive and the negative cables close together.
4. Place the welding cables at or close to floor level.
5. Remove signalling cables in the welding area from the supply
cables.
6. Protect signalling cables in the welding area, e.g. with
selective screening.
7. Use separately-insulated mains supply cables for sensitive
electronic equipment.
8. Screening of the entire welding installation may be con-
sidered under special circumstances and for special applica-
tions.
WARNING
Arc welding and cutting can be dangerous to the user, people working nearby, and the surroundings if the
equipment is handled or used incorrectly. Therefore, the equipment must only be used under the strict
observance of all relevant safety instructions. In particular, your attention is drawn to the following:
Electricity
- The welding equipment must be installed according to safety regulations and by a properly trained and qualified
person.
- Avoid all contact with live components in the welding circuit and with electrodes and wires if you have bare
hands. Always use dry welding gloves without holes.
- Make sure that you are properly and safely earthed (e.g use shoes with rubber sole).
- Use a safe and stable working position (e.g. avoid any risk of accidents by falling).
- Make sure that the welding equipment is correctly maintained. In the case of damaged cables or insulation work
must be stopped immediately in order to carry out repairs.
- Repairs and maintenance of the equipment must be carried out by a properly trained and qualified person.
Light and heat emissions
- Protect the eyes as even a short-term exposure can cause lasting damage to the eyes. Use a welding helmet
with suitable radiation protection glass.
- Protect the body against the light from the arc as the skin can be damaged by welding radiation. Use protective
clothes, covering all parts of the body.
- The place of work should be screened, if possible, and other persons in the area warned against the light from
the arc.
Welding smoke and gases
- The breathing in of the smoke and gases emitted during welding is damaging to health. Make sure that any
exhaust systems are working properly and that there is sufficient ventilation.
Fire hazard
- Radiation and sparks from the arc represent a fire hazard. As a consequence, combustible materials must be
removed from the place of welding.
- Working clothing should also be secure against sparks from the arc (e.g. use a fire-resistant material and watch
out for folds and open pockets).
Noise
- The arc generates surface noise according to welding task. In some cases, use of hearing aids is necessary.
Use of the machine for other purposes than it is designed for (e.g. to unfreeze water pipes) is strongly
deprecrated. If occasion should arise this will be carried out without responsibility on our part.
