6. Eloigner les materiaux inflammables ou les recouvrir afin de prevenir tout risque d’incendie du aux etincelles. 7. Quand on ne soude pas, poser la pince a une endroit isole de la masse. Un court-circuit accidental peut provoquer un echauffement et un risque d’incendie. 8. S’assurer que la masse est connectee le plus pres possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres endroits eloignes de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de lev- age, cables de grue, ou autres circuits. Cela peut provoquer des risques d’incendie ou d’echauffement des chaines et des cables jusqu’a ce qu’ils se rompent. 9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particulierement important pour le soudage de toles galvanisees plombees, ou cadmiees ou tout autre metal qui produit des fumees toxiques. 10. Ne pas souder en presence de vapeurs de chlore provenant d’operations de degraissage, nettoyage ou pistolage. La chaleur ou les rayons de l’arc peuvent reagir avec les vapeurs du solvant pour produire du phosgene (gas fortement toxique) ou autres produits irritants. 11.

PRECAUTIONS DE SURETE POUR LES MACHINES A SOUDER A TRANSFORMATEUR ET A REDRESSEUR 1. Relier a la terre le chassis du poste conformement au code de l’electricite et aux recommendations du fabricant. Le dispositif de montage ou la piece a souder doit etre branche a une bonne mise a la terre. 2. Autant que possible, I’installation et l’entretien du poste seront effectues par un electricien qualifie. 3. Avant de faires des travaux a l’interieur de poste, la debranch- er a l’interrupteur a la boite de fusibles. 4. Garder tous les couvercles et dispositifs de surete a leur place. Mar. ‘93 v v SAFETY Electromagnetic Compatibility (EMC) Conformance Products displaying the CE mark are in conformity with European Community Council Directive of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (89/336/EEC). It was manufactured in conformity with a national standard that implements a harmonized standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment. It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use. Introduction All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions are received by other equipment, electrical interference may result. Electrical emissions may affect many kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions may be required when a welding power source is used in a domestic establishment. 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 of 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 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 addition...
