INDIVIDUAL PROTECTION & OTHERS

Arc welding can be dangerous and can cause serious injury or even death. Welding exposes the user to dangerous heat, arc rays, electromagnetic elds, risk of electric shock, noise and gas fumes. People wearing pacemakers are advised to consult a doctor before using the welding machine. Protect yourself and others. Ensure the following safety precautions are taken: In order to protect you from burns and radiations, wear clothing without cus. These clothes must be insulating, dry, reproof, in good condition, and cover the whole body. Wear protective gloves which guarantee electrical and thermal insulation. Wear welding protective gear for the whole body: hood, gloves, jacket, trousers... (variable, depending on the application). Protect your eyes during cleaning procedures. Contact lenses are prohibited during use. It may be necessary to install reproof welding curtains to protect the area against arc rays, weld spatter and sparks. Inform people who are around the working area to never look at the arc ray or the molten metal, and to wear protective clothes. Wear ear protection if the work exceeds the authorised noise limit. The same applies to anyone in the welding area. Keep hands, hair and clothes away from moving parts such as fans, and engines. Never remove the safety covers from the cooling unit when the machine is plugged in. The manufacturer is not liable for any injury or damage due to non-compliance with the safety precautions. Parts that have just been welded will be hot and may cause burns when touched. During the maintenance of the torch, make sure that the torch has suciently cooled down and wait at least 10 minutes before any operation. When using a water- cooled torch, make sure that the cooling unit is switched on to avoid any burns that could potentially be caused by the liquid. It is important to secure the working area before leaving it to ensure protection of the goods and the safety of people.

WELDING FUMES AND GAS

Fumes, gas and dust produced during welding are hazardous to health. It is mandatory to ensure adequate ventilation and/ or extraction to keep fumes and gas away from the work area. Using an air fed welding helmet is recommended in case of insucient ventilation in the workplace. Check that the air supply is eective by referring to the recommended safety regulations. Precautions must be taken when welding in small areas, and the operator will need supervision from a safe distance. Welding specic pieces of metal containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user will also need to remove the grease from the workpiece before welding. Gas cylinders must be stored in an open or ventilated area. They must be stored vertically and held by a support or trolley to limit the risk of fall. Do not weld in areas where grease or paint are stored.12

Protect the entire welding area. Flammable materials must be moved to a minimum safe distance of 11 meters. A re extinguisher must be readily available near the welding operations. Be careful of spatter and sparks, even through cracks. It can be the source of a re or an explosion. Keep people, ammable materials/objects and containers that are under pressure at a safe distance. Welding in closed containers or pipes should be avoided and , if they are opened, they must be emptied of any ammable or explosive material (oil, fuel, gas ...). Grinding operations should not be directed towards the device itself or any ammable materials. ELECTRICAL SAFETY The electrical mains used must have an earth terminal. Use the recommended fuse size. An electric shock could cause serious injuries or potentially even deadly accidents. Never touch live parts inside and outside of the device when it is powered on (Torches, clamps, cables, electrodes) as they are connected to the welding circuit. Before opening the device, it is imperative to disconnect it from the mains and to wait for 2 minutes in order for the capacitors to release the energy. Do not touch the torch or electrode holder and the earth clamp at the same time. Be sure to change the cables and torches if they are damaged, to be performed by qualied and authorized personnel. The dimensions and rating of the accessories must be suitable. Always wear dry clothes which are in good condition in order to be isolated from the welding circuit. Always wear insulated shoes, regardless of the environment in which you work in.

TRANSPORTATION OF THE MACHINE

It is preferable to drain the cooling unit before transport. Do not place/carry the unit over people or objects. EQUIPMENT INSTALLATION Rules to follow:

The equipment can be used outside in accordance with the IP23 protection certication. The manufacturer GYS 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. A yearly maintenance is recommended.

• Ensure the machine is unplugged from the mains, and then wait 2 minutes before carrying out maintenance work. Inside, voltages and currents are high and dangerous.

• Remove regularly the casing and any excess of 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 or connection cables are damaged, they must be replaced by the manufacturer, its after sales service or an equally qualied person to prevent danger.

• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation. The cooling liquid must be changed every 12 month in order to avoid sediments which could block the torch cooling circuit. Any leak or residual uid, after use, must be handled within the appropriate purication factory. If possible, recycle the product. It is prohibited to empty the product in a river, a sceptic tank or a draining system. The diluted uid must not be emptied in the sewers, unless euthorised by the local regulations.13

Only qualied personnel authorised by the manufacturer should perform the installation of the welding equipment. During the installation, the operator must ensure that the machine is disconnected from the mains. Connecting generators in serial or in parallel is forbidden.

M6x16 (x4) M6 (x4) M6x16 (x4) M6 (x4) COOLANT Make sure that the cooling unit is turned o before disconnecting the liquid inlet and/or outlet hoses of the torch. The coolant is harmful and can irritate the eyes and skin. Hot liquid may cause burns. Risk of burns due to hot liquid Never drain the cooling unit immediately after use. The liquid contained inside is boiling, wait until it cools down before draining. FILLING max min The operator must ll the tank up to its maximum indicated on the front of the cooling unit but never under the minimum line or a warning message will be displayed on the screen. It is essential to use a specic welding coolant with low electrical conductivity, being anticor- rosive and anti-freezing (ref. 052246). The use of any other coolant (in particular the automotive standard coolant), can lead, by electrolysis eect, to the accumulation of solid deposits in the cooling system, thus damaging it and also blocking the circuit. This recommended maximum level is essential to optimise the duty cycles of the cooled torch. Any damage to the machine due to the use of a dierent coolant than the recommended type will not be covered by the guarantee. TWINCOOL CONNECTION NEOFEED 1NEOFEED 2 Follow the connection diagram shown to avoid damaging the lamp. The wire feeder number is indicated on the interface. Example: Wire feeder no.118

For the rst application, the pump start-up could be dicult and generate a defect water ow. To start it correctly, it is recommended to use the above hose and follow the instructions below to purge the system: Fill the cooling unit to its maximum level to facilitate priming. EXAGON / TITAN : - Connect the quick coupling to the cold water outlet of the unit and place the other end in an empty container (ideally a bottle) - Connect a torch to the product, then briey squeeze the trigger to start the pump - Once the pump is activated (container that lls with coolant), stop the product by turning o the main welding generator switch. - Disconnect the start pipe, put the liquid back into the cooling unit and connect the beam correctly (see user manual of the welding generator). TITANIUM / NEOPULSE / NEOFEED : - Connect the quick coupling to the cold water outlet of the unit and place the other end in an empty container (ideally a bottle) - In the « Settings/Cooling unit » menu, press the icon to start the start-up procedure. - Once the pump activated (container that lls with coolant), stop the cooling unit by pressing one of the buttons on the HMI. - Disconnect the starting pipe, put the liquid back into the cooling unit: your pump is started.

IGNITION OF THE PUMP SHAFT

Long periods without use and impurities in the coolant can cause the cooling pump to jam. Pump shaft priming procedure: 1/ Switch o the power source. 2/ Insert a at head screwdriver (Ø 9 mm max.) in the center of the pump shaft, passing through the service hole. Then turn the screwdri- ver clockwise until the pump shaft rotates smoothly again. 3/ Remove the screwdriver. 4/ Switch on the power source.
