Instructions For Electromagnetic Compatibility; Methods Of Reducing Emissions; Section 1; Introduction - EPS HPS Helios 160 Manual De Instrucciones

The following instructions should be read by all concerned before installing or using this device. In case of any doubt contact
your distributor or directly the producer to get all the informations that may be needed.
The user is responsible for installing and using the welding equipment according to the manufacturers instructions. If
electromagnetic disturbances are detected then it shall be responsibility of the user of the welding equipment to resolve the
situation with the technical assistance of the manufacturer. In some cases this remedial action may be as simple as earthing the
welding circuit. In other cases it could involve constructing an electromagnetic screen enclosing the power source and the work
complete with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where they are no
longer troublesome.
Note - The welding circuit may or may not be earthed for safety reasons. Changing the earthing arrangements should only be
authorized by a person who is competent to asses whether the changes increase the risk of injury, e.g. by allowing parallel
welding current return paths which may damage the earth circuits of other equipment.
Assessment of area
Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the
surrounding area. The following shall be taken into account:
a) Other supply cables, control cables, signaling and telephone cables above, below and adjacent to the welding equipment;
b) Radio and television transmitters and receivers;
c) Computer and other control equipment;
d) Safety critical equipment, e.g. guarding of industrial equipment;
e) The health of the people around, e.g. the use of pacemakers and hearing aids;
f) Equipment used for calibration or measurement;
g) The immunity of other equipment in the environment. The user shall ensure that other equipment being used in the
environment is compatible. This may require additional protection measures;
h) The time of the day that welding or other activities are to be carried out.
The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking
place. The surrounding area may extend beyond the boundaries of the premises.

METHODS OF REDUCING EMISSIONS

Mains supply
Welding equipment should be connected to the mains supply according to the manufacturers recommendations. If interference
occurs, it may be necessary to take additional precautions such as filtering of the mains supply. Consideration should be given
to shielding the supply cable of permanently installed welding equipment, in metallic conduit or equivalent. Shielding should be
electrically continuous throughout its length. The shielding should be connected to the welding power source so that good
electrical contact is maintained between the conduit and the welding power source enclosure.
Maintenance of the welding equipment
The welding equipment should be routinely maintained according to the manufacturers recommendations. All access and
service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding
equipment should not be modified in any way except for those changes and adjustment covered in the manufacturers
instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according to
the manufacturers recommendations.
Welding cables
The welding cables should be kept as short as possible and should be positioned close together, running at or close to the floor
level.

1.1 INTRODUCTION

Arc welding processes as developed after many years of welding experience can be used with a high degree of safety provided
that proper care and attention is given to common sense practices and to manufacturer's recommended methods.
It is therefore imperative that management and safety personnel make sure that all personnel who will operate or maintain the
welding equipment be given the opportunity to read this information.

1.2 GENERAL PRECAUTIONS

1.2.1 Prevention of burns
Sparks, slag, hot metal and radiations produced by the welding arc can be seriously damaging to the eyes and skin. As the
operator or any other person comes close to the welding area, the level of exposure increases rapidly. Proper protective clothing
and equipment must be worn by the operator and any other persons working in the vicinity of the arc. Gauntlet gloves designed
for use in welding, safety shoes, and a hat are required. Flame retardant clothing which covers all exposed areas and cuffless
trousers to prevent entry of sparks and slag are recommended. Proper safety goggles or glasses with side shields of the
