Installation and Use The user is responsible for installing and using the welding equipment according to the manufacturer s instructions If electromagnetic disturbances are detected then it shall be the 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 grounding the welding circuit see Note In other cases it could involve construction 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 according to national codes Changing the earthing arrangements should only be authorized by a person who is compe tent to access whether the changes will 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 prob lems 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 contro
