PROTECTION OF THE INDIVIDUALS

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. Ensure ear protection is worn by the operator if the work exceeds the authorised noise limit (the same applies to any person in the welding area). Stay away from moving parts (e.g. engine, fan...) with hands, hair, clothes etc... Never remove the safety covers from the cooling unit when the machine is plugged in - The manufacturer is not responsible for any accident or injury that happens as a result of not following these safety precautions. 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. Do not weld in areas where grease or paint are stored.16

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 lead to suocation 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 wary of temperature changes or exposure to 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 ames. 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 or deadly accidents. 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 TIG 300 DC do 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 TIG 220 DC complies with the IEC 61000-3-12 standard. This equipment TIG 220 DC complies with IEC 61000-3-11 if the power supply network’s impedance at the electrical installation’s connection point is inferior to the network’s maximum admissible impendance Zmax = 0.29 Ohms. ELECTROMAGNETIC INTERFERENCES The electric currents owing through a conductor cause electrical and magnetic elds (EMF). The welding current generates an EMF eld around the welding circuit and the welding equipment. The EMF elds may disrupt some medical implants, such as pacemakers. Protection measures should be taken for people wearing medical implants. For example, access restrictions for passers-by or an individual risk evaluation for the welders. All welders should take the following precautions in order to minimise exposure to the electromagnetic elds (EMF) generated by the welding circuit::

• position the welding cables together – if possible, attach them;

• keep your head and torso as far as possible from the welding circuit;

• never enroll the cables around your body;

• never position your body between the welding cables. Hold both welding cables on the same side of your body;

• connect the earth clamp as close as possible to the area being welded;

• do not work too close to, do not lean and do not sit on the welding machine

• do not weld when you’re carrying the welding machine or its wire feeder.17

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. RECOMMANDATIONS 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 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 ground. 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 - due to 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 equipment. 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 WELDING MACHINE The machine is tted with handle to facilitate transportation. Be careful not to underestimate the machine’s weight. The handle(s) cannot be used for slinging. Do not use the cables or torch to move the machine. The welding equipment must be moved in an upright position. Never lift the machine while there is a gas cylinder on the support shelf. A clear path is available when moving the item. Do not place/carry the unit over people or objects.18

• Ensure the work area has sucient ventillation for welding, and that there is easy access to the control panel.

• The machine must not be used in an area with conductive metal dusts.

• The machine must be placed in a sheltered area away from rain or direct sunlight.

• The machine protection level is IP21, which means : - Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and, - Protection against vertically falling drops.

• The machine protection level is IP23, which means : - Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and, - Protection against the rain inclined at 60% towards the vertical. These devices can be used outside in accordance with the IP23 protection index. The power cables, extensions and welding cables must be fully uncoiled to prevent overheating. The manufacturer does not incur any responsability regarding damages to both objects and persons that result from an incorrect and/or dangerous use of the machine . MAINTENANCE / RECOMMENDATIONS

• Maintenance should only be carried out by a qualied person. Annual maintenance is recommended.

• Ensure the machine is unplugged from the mains, and wait for two minutes before carrying out maintenance work. DANGER High Voltage and Currents inside the machine.

• Remove the casing 2 or 3 times a year to remove any excess dust. Take this opportunity to have the electrical connections checked by a qualied person, with an insulated tool.

• Regularly check the condition of the power supply cable. If the power cable is damaged, it must be replaced by the manufacturer, its after sales service or an equally qualied person.

• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.

• Do not use this equipment to thaw pipes, to charge batteries, or to start any engine.

INSTALLATION – PRODUCT OPERATION

Only qualied personnel authorized by the manufacturer should perform the installation of the welding equipment. During set up, the operator must ensure that the machine is unplugged. Connecting generators in a series or a parallel circuit is forbidden. HARDWARE DESCRIPTION (FIG-1) These TIGs are inverter welding power sources for direct current (DC) refractory electrode welding (TIG) and shielded metal arc welding (MMA). The TIG process requires gas shielding (Argon). The MMA process can weld any type of electrode: rutile, basic, stainless steel and cast iron. These TIGs can be equipped with a manual remote control (ref. 045675) or a foot pedal (ref. 045682). The TIG 300 DC can be equipped with an automatic command (CONNECT-5).

• The TIG 300 DC is supplied with a 5-pole (3P+N+PE) 400V 16A three-phase plug of type EN 60309-1 and is supplied from a 400V (50 - 60 Hz) three-phase electrical installation WITH earth. This equipment must only be used on a three-phase four-wire power system with the neutral connected to earth. The TIG 220 DC is delivered with a single-phase 3-pole (P+N+PE) 230V 16A CEE17 plug, is equipped with a «Flexible Voltage» system and is supplied on an electrical installation with earth between 110V and 240V (50 - 60 Hz). The eective absorbed current (I1e) is indicated on the welding current source and for the maximum operating conditions. Check that the power supply and its protection (fuse and/or circuit breaker) are compatible with the current required in use. In some countries, it may be necessary to change the plug to allow use at maximum conditions. The user must ensure that the plug is accessible.

• The welding current source goes into protection if the supply voltage is less than or greater than 15% of the specied voltage(s) (a fault code will appear on the keyboard display).

• The TIG 300 DC is switched on by turning the on/o switch (7) to position I, conversely, it is switched o by turning to position O. The TIG 220 DC is switched on by pressing the standby button. Caution! Never switch o the power supply when the welding current source is under load.

• Fan behaviour: In MMA mode, the fan runs continuously. In TIG mode, the fan runs only during the welding phase and then stops after cooling

• Warning: Increasing the length of the torch or return cables beyond the maximum length specied by the manufacturer will increase the risk of electric shock.19

The machine can work with generators as logn as the auxiliary power matches these requirements : - The voltage must be AC, always superior to 400Vac ±15%, and the peak voltage below 700V, - The frequency must be between 50 and 60 Hz. It is imperative to check these requirements as several generators generate high voltage peaks that can damage these machines.

USE WITH EXTENSION CABLES

All extension cables must have an adequate size and section, relative to the machine’s voltage . Use an extension that complies with national safety regulations.

• TIG DC This welding mode in direct current (DC) is designed for ferrous metal such as steel, stainless steel or even copper and its alloys.
• TIG DC Pulsed This pulse welding mode chains high current pulses (I, welding pulse) then low current pulses (I_cold, pulses to cool the piece). This pulse mode allows to assemble pieces while limiting high temperatures.Example : The I welding current is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A. F(Hz) is set to 10Hz, the signal period will be 1/10Hz = 100ms. Every 100ms, a 100A pulse then a 50A pulse will succeeed each other.The choice of frequency - If welding with TIG electrodes, then F(Hz) synchronised to the gesture,- If thin plate without TIG electrodes (< 8/10 mm), F(Hz) >> 10Hz- If special metal requiring a welding pool sweep for degasing, then F(Hz) >> 100Hz• Tack weld feature SPOTTIG SPOTThe grey areas are not useful for this mode.• TIG DC - Advanced menuThe Start and Stop stages of the welding cycle can be set.
