INDIVIDUAL PROTECTIONS AND OTHERS

Arc welding can be dangerous and can cause serious and even fatal injuries. Welding exposes the user to dangerous heat, arc rays, electromagnetic elds, noise, gas fumes, and electrical shocks. People wearing pacemakers are advised to consult with their doctor before using this device. To protect oneself as well as the other, ensure the following safety precautions are taken: In order to protect you from burns and radiations, wear clothing without cus. These clothes must be insulated, dry, reproof and in good condition, and cover the whole body. Wear protective gloves which guarantee electrical and thermal insulation. Use sucient welding protective gear for the whole body: hood, gloves, jacket, trousers... (varies depending on the application/ operation). Protect the eyes during cleaning operations. Do not operate whilst wearing contact lenses. It may be necessary to install reproof welding curtains to protect the area against arc rays, weld spatters and sparks. Inform the people around the working area to never look at the arc nor the molten metal, and to wear protective clothes. Wear noise protection headphones if the welding process becomes louder than the permissible limit (this is also applicable to anyone else in the welding area). Keep hands, hair and clothing away from moving parts (the ventilation fan, for example). Never remove the cooling unit housing protections when the welding power source is live, the manufacturer cannot be held responsible inthe event of an accident. The pieces that have just been welded are hot and may cause burns when manipulated. During maintenance work on the torch or the electrode holder, you should make sure it’s cold enough and wait at least 10 minutes before any intervention. The cooling unit must be on when using a water cooled torch in order to ensure that the liquid does not cause any burns. ALWAYS ensure the working area is left as safe and secure as possible to prevent damage or accidents.

WELDING FUMES AND GAS

The fumes, gases and dust produced during welding are hazardous. It is mandatory to ensure adequate ventilation and/or extraction to keep fumes and gases away from the work area. An air fed helmet is recommended in cases of insucient air supply in the workplace. Check that the air intake is in compliance with safety standards. Care must be taken when welding in small areas, and the operator will need supervision from a safe distance. Welding certain pieces of metal containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user will also need to degrease the workpiece before welding. Gas cylinders must be stored in an open or ventilated area. The cylinders must be in a vertical position secured to a support or trolley.15

Do not weld in areas where grease or paint are stored.

FIRE AND EXPLOSIONS RISKS

Protect the entire welding area. Compressed gas containers and other inammable material must be moved to a minimum safe distance of 11 meters. A re extinguisher must be readily available. Be careful of spatter and sparks, even through cracks. It can be the source of a re or an explosion. Keep people, ammable objects and containers under pressure at a safe distance. Welding of sealed containers or closed pipes should not be undertaken, and if opened, the operator must remove any inammable or explosive materials (oil, petrol, gas...). Grinding operations should not be directed towards the device itself, the power supply or any ammable materials. GAS BOTTLE Gas leaking from the cylinder can create a hazard if present in high concentrations around the work area. Transport must be done safely: Cylinders closed and product o. Always keep cylinders in an upright position securely chained to a xed support or trolley. Close the bottle after any welding operation. Be careful with gas bottles placed in areas of high temperature, or in sunlight. Cylinders should be located away from areas where they may be struck or subjected to physical damage. Always keep gas bottles at a safe distance from arc welding or cutting operations, and any source of heat, sparks or ame. Be careful when opening the valve on the gas bottle, it is necessary to remove the tip of the valve and make sure the gas meets your welding requirements. ELECTRIC SAFETY The machine must be connected to an earthed electrical supply. Use the recommended fuse size. An electrical discharge can directly or indirectly cause serious accidents, if not deadly. Do not touch any live part of the machine (inside or outside) when it is plugged in (Torches, earth cable, cables, electrodes) because they are connected to the welding circuit. Before opening the device, it is imperative to disconnect it from the mains and wait 2 minutes, so that all the capacitors are discharged. Do not touch the torch or electrode holder and earth clamp at the same time. Damaged cables and torches must be changed by a qualied and skilled professional. Make sure that the cable cross section is adequate with the usage (extensions and welding cables). Always wear dry clothes in good condition, in order to be insulated from the electrical circuit. Wear insulating shoes, regardless of the environment in which you work in. EMC CLASSIFICATION These Class A devices are not intended to be used on a residential site where the electric current is supplied by the public network, with a low voltage power supply. There may be potential diculties in ensuring electromagnetic compatibility on these sites, because of the interferences, as well as radio frequencies. This equipment does not comply with IEC 61000-3-12 and is intended to be connected to private low-voltage systems interfacing with the public supply only at the medium- or high-voltage level. On a public low-voltage power grid, it is the responsibility of the installer or user of the device to ensure, by checking with the operator of the distribution network, which device can be connected. This equipment complies with the IEC 61000-3-11 standard. ELECTROMAGNETIC INTERFERENCES The electric currents owing through a conductor cause electrical and magnetic elds (EMF). All welders should use the following guidelines to minimize exposure to electromagnetic elds from the welding circuit. - Regroup the electrode cables and earth clamp. If possible, attach them with tape - Do not roll the electrode cable, torch or the earth clamp around the body. - Do not stand between the cables. If the electrode cable or torch is on the right, the work cable should also be on the right. - Connect the earth cable to the workpiece, as close as possible to the welding area. - Do not work next to the welding power source.16

People wearing pacemakers are advised to consult their doctor before using this device. Exposure to electromagnetic elds while welding may have other health eects which are not yet known. RECOMMENDATIONS TO ASSES THE AREA AND WELDING INSTALLATION Overview The user is responsible for installing and using the arc welding equipment in accordance with the manufacturer’s instructions. If electromagnetic disturbances are detected, it is be the responsibility of the user of the arc welding equipment to resolve the situation with the manufacturer’s technical assistance. In some cases, this remedial action may be as simple as earthing the welding circuit. In other cases, it may be necessary to construct an electromagnetic shield around the welding power source and around the entire piece by tting input lters. In all cases, electromagnetic interferences must be reduced until they are no longer bothersome. Welding area assessment Before installing the machine, the user must evaluate the possible electromagnetic problems that may arise in the area where the installation is planned. . In particular, it should consider the following: a) the presence of other power cables (power supply cables, telephone cables, command cable, etc...)above, below and on the sides of the arc welding machine. b) television transmitters and receivers ; c) computers and other hardware; d) critical safety equipment such as industrial machine protections; e) the health and safety of the people in the area such as people with pacemakers or hearing aids; f) calibration and measuring equipment g)The isolation of the equipment from other machinery. The user will have to make sure that the devices and equipments that are in the same room are compatible with each other. This may require extra precautions; h) make sure of the exact hour when the welding and/or other operations will take place. The surface of the area to be considered around the device depends on the the building’s structure and other activities that take place there. The area taken in consideration can be larger than the limits determined by the companies. Welding area assessment Besides the welding area, the assessment of the arc welding systems intallation itself can be used to identify and resolve cases of disturbances. The assessment of emissions must include in situ measurements as specied in Article 10 of CISPR 11. In situ measurements can also be used to conrm the eectiveness of mitigation measures. RECOMMENDATION ON METHODS OF ELECTROMAGNETIC EMISSIONS REDUCTION a. National power grid: The arc welding machine must be connected to the national power grid in accordance with the manufacturer’s recommendation. If interferences occur, it may be necessary to take additional preventive measures such as the ltering of the power suplly network. Consideration should be given to shielding the power supply cable in a metal conduit. It is necessary to ensure the shielding’s electrical continuity along the cable’s entire length. The shielding should be connected to the welding current’s source to ensure good electrical contact between the conduct and the casing of the welding current source. b. Maintenance of the arc welding equipment: The arc welding machine should be be submitted to a routine maintenance check according to the manufacturer’s recommendations. All accesses, service doors and covers should be closed and properly locked when the arc welding equipment is on.. The arc welding equipment must not be modied in any way, except for the changes and settings outlined in the manufacturer’s instructions. The spark gap of the arc start and arc stabilization devices must be adjusted and maintained according to the manufacturer’s recommendations. c. Welding cables: Cables must be as short as possible, close to each other and close to the ground, if not on the groud. d. Electrical bonding: consideration shoud be given to bonding all metal objects in the surrounding area. However, metal objects connected to the workpiece increase the riskof electric shock if the operator touches both these metal elements and the electrode. It is necessary to insulate the operator from such metal objects. e. Earthing of the welded part: When the part is not earthed because for electrical safety reasons or because of its size and its location (which is the case with ship hulls or metallic building structures), the earthing of the part can, in some cases but not systematically, reduce emissions. It is preferable to avoid the earthing of parts that could increase the risk of injury to the users or damage other electrical equipments. If necessary, it is appropriate that the earthing of the part is done directly, but in some countries that do not allow such a direct connection, it is appropriate that the connection is made with a capacitor selected according to national regulations. f. Protection and plating: The selective protection and plating of other cables and devices in the area can reduce perturbation issues. The protection of the entire welding area can be considered for specic situations.

TRANSPORT AND TRANSIT OF THE MACHINE
