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 depen- ding 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 manufac- turer 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 mainte- nance 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.12

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.

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 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.13

This equipment complies with the IEC 61000-3-12 standard. This equipment 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 = 0.281 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. 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 ASSESS THE WELDING 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.14

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(s) 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. Do not place/carry the unit over people or objects. Never lift the machine while there is a gas cylinder on the support shelf. A clear path is available when moving the item. EQUIPMENT INSTALLATION

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. It is recommended to use the welding cables supplied with the unit in order to obtain the optimum product settings. HARDWARE DESCRIPTION These welding are, Inverter, portable welder, for covered electrode and TIG Lift in DC. It allows welding with rutiles, basic, stainless steel. In TIG, it allows to weld most of metals except aluminium and alloys. It is protected for a use on electric generators (Alim 110V-240 V AC).

POWER SUPPLY – START UP

• These machine are delivered with a 230V socket /16A plug type EEC7/7. The GYSMI E200 FV integrate a « Flexible Voltage » system. It has to be on a power supply variable between 110V and 240V (50 – 60 Hz) WITH earth. The absorbed eective current (I1e) is shown on the machine, for maximal using conditions. Check that the power supply and its protection (fuse and/or circuit-breaker) is compatible with the necessary current during use. In some countries, the change of plug can be necessary to allow a use at maximal conditions. The welder must be installed so that the main plug is accessible.

• The start-up is done by pressing « » The device turns into protection mode if the supply voltage is over 265V for the single-phase products (the sсreen dis- plays ). Normal operation will resume when the voltage has returned to its nominal range.

CONNECTION ON A GENERATOR

The machine can work with generators as long as the auxiliary power matches these requirements : - The voltage must be AC, always set as specied, and the peak voltage below 400V, - 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. MMA WELDING (ELECTRODE)

CONNECTIONS AND RECOMMENDATIONS

• Connect the cables, electrode holder and earth clamp to the connectors,

• Follow the welding polarities and power recommendations indicated on the electrodes boxes,

• Remove the electrode from the electrode holder when the machine is not in use.

• The machine has 3 features exclusive to Inverters: - The Hot Start creates an overcurrent at the beginning of the welding. - The Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool. - The Anti-Sticking technology makes it easier to unstick the electrode from the metal.

• MMA STANDARD The MMA STANDARD mode is recommended for most applications. It can weld any type of electrode: rutile, basic, cel- lulosic... and on any materials: steel, stainless steel, cast iron.16

When the machine is in MMA Standard mode:• Press shortly the switch (5).• «HS» (Hot Start) blinks and a number is displayed.(display (1)).• Set the desired percentage using the keys (4).• The machine is ready to operate.• MMA PULSEThe MMA Pulsed mode is recommended for vertical-up welding (PF) The pulse mode keeps the weld pool cold and eases the transfer of matter. Without the pulse mode, vertical-up welding requires a dicult «Christmas tree» triangular movement. With the MMA Pulsed mode, this movement is no longer required and a simple straight up movement is enough (depending on the thickness of the workpiece). If you wish to widen your weld pool, a simple lateral movement is enough (similar to normal welding). In this case the pulse current frequency can be adjusted on the display. This process allows greater control during ver- tical-up welding.Activating the MMA Pulsed mode and setting the current: PULSE When the machine is in MMA Standard mode:• Press the switch (5) for 3 seconds.• «PLS» (Pulsed) blinks and a number is displayed(display (1)).• Set the desired current using the keys (4).• The machine is ready to operate.17
