INDIVIDUAL PROTECTION & OTHERS

Cutting can be dangerous and cause severe injuries. Cutting exposes individuals to a dangerous source of heat, arc rays, electromagnetic elds (special precautions need to be taken by people that have a pacemaker), risk of electrocution, noise and gas fumes. To protect oneself as well as others, ensure the following safety precautions are taken: In order to protect you from burns and radiations, wear clothing without turn-ups or cus. These clothes must be insulating, dry, reproof, in good condition and cover the whole body. Wear protective gloves whichprovide electrical and thermal insulation. Use sucient cutting protective gear for the whole body: hood, gloves, jacket, trousers...(varies depending on the application/ operation) Protect the eyes during cleaning operations. Contact lenses are prohibited during use. It may be necessary to install reproof welding curtains in order to protect against safety hazards such as arc rays, weld spatters and sparks. Ensure that people around the cutting area do not look at the arc or the molten metal and 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 cutting area). Keep hands, hair and clothes away from moving parts such as fans, and motors. 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 caused due to non-compliance with the safety precautions. Parts that have previously been cut will be hot and may cause burns if touched. If maintenance of the torch is required, ensure that it is given sucient time to cool down by waiting at least 10 minutes. 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

The fumes, gas and dust generated by cutting are a potential health hazard. 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. When cutting in small areas, operators must be supervised from a safe distance. Cutting certain materials containing lead, cadmium, zinc, mercury or beryllium can be particularly hazardous. It is also recommended to degrease the parts before cutting them. 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 cut in areas where grease or paint are stored.19 NEOCUT 105 / 125

Protect the entire working area and ensure that ammable items are stored at a distance of at least 11 meters. Fire extinguishing equipment must be kept in close proximity when cutting materials. Be careful of weld spatter and sparks, even through cracks. If not careful then this could potentially lead to a re or an explosion. Keep people, ammable materials/objects and containers that are under pressure at a safe distance. Cutting in containers or pipes should be avoided and, if they are open, then ammable or explosive materials must be removed (oil, fuel, gas...). Grinding operations should not be carried out close to the power supply or 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. Do not touch any live part of the machine (inside or outside) when it is plugged in (Torches, cables, clamps) because they are connected to the cutting 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 technician. Make sure that the cable cross section is adequate with the usage (extensions and welding cables). Always wear clothing that is dry and in good condition in order to shield yourself from the cutting circuit. Wear insulating shoes, regardless of the workplace/environment in which you work in.

EMC MATERIAL CLASSIFICATION

This Class A machine is not intended to be used on a residential site where the electric current is supplied by the domestic low-voltage power grid. There may be potential diculties in ensuring electromagnetic compatibility at these sites, due to conducted interferences as well as radiation. 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 power grid only at the medium- or high-voltage level. If connected to a public low-voltage power grid, the installer or user of the machine has to ensure, by checking with the network operator, that the device can be connected. This equipment complies with the IEC 61000-3-11 standard. ELECTROMAGNETIC INTERFERENCES The electric current owing through any conductor causes electrical and magnetic elds (EMF). The cutting current generates an EMF around the cutting circuit and the cutting equipment. The EMF electromagnetic elds can interfere with certain medical implants, such as pacemakers. Protective measures must be taken for people having medical implants. For example, by restricting access to passers-by or conducting an individual risk evaluation for the users. All users should take the following precautions in order to minimise exposure to the electromagnetic elds (EMF) generated by the cutting circuit:

• position the cutting cables together - if possible, attach them;

• keep your head and upper body as far as possible from the cutting circuit;

• never wrap the cable around your body;

• Never position your body between the cables. Hold both cutting cables on the same side of your body;

• Connect the earth clamp as close as possible to the area being cut;

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

• do not cut when you’re carrying the machine. 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 identied. RECOMMENDATIONS FOR WELDING AREA ASSESSMENT AND CUTTING General points The user is responsible for the installation and use of the arc cutting equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected, the user is responsible for resolving the situation with the manufacturer’s technical support. In certain cases, this corrective action may be as simple as earthing the cutting circuit. In other cases, it may be necessary to construct an electromagnetic shield around the cutting power source and around the entire piece by tting input lters. In all cases, electromagnetic interferences must be reduced until they are no longer an issue.20 NEOCUT 105 / 125

Cutting area assessment Before installing the machine, the operator must evaluate the possible electromagnetic problems that may arise in the area where the installation is planned. The following elements should be considered: a) the presence (above below and next to the arc cutting machine) of other power cables, remote cables and telephone cables; b) television transmitters and receivers; c) computers and other hardware d) critical safety equipment such as industrial machine protection; 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 other pieces of equipment which are in the same area. The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This may require extra precautions; h) the time of day during the cutting or other activities have to be performed. The dimension of the cutting area that has to be considered depends on the size and shape of the building and the type of work undertaken. The area taken into consideration might go beyond the limits of the installation. Cutting installation assessment Besides the welding area, the assessment of the arc cutting system installation itself can be used to identify and resolve cases of distrubances 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.

RECOMMENDED METHODS TO REDUCE ELECTROMAGNETIC EMISSIONS

a. National power grid: the plasma cutting machine must be connected to the national power grid in accordance with the manufacturer’s recommendation. In case of interferenc, it may be necessary to take additional precautions such as the ltering of the power supply network. Consideration should be given to shield the power supply cable in a metal frame or equivalent from a permanent cutting installation. It is necessary to ensure the electrical continuity of the frame along its entire length. The frame should be connected to the cutting machine to ensure good electrical contact between the conduct and the casing of the cutting machine. b. Maintenance of the arc cutting equipment: the arc cutting machine should be subject to a routine maintenance check according to the recommendations of the manufacturer. All accesses, service doors and covers should be closed and properly locked when the arc welding equipment is on. The arc cutting 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 starts and arc stabilization devices must be adjusted and maintained according to manufacturer’s recommendations. c. Cutting cables: cables must be as short as possible, close to each other and close to the ground, if not on the ground. d. Equipotential bonding: consideration should be given to bond all metal objects in the surrounding area. However, metal objects connected to the workpiece increase the risk of electric shock if the operator touches both the metal parts and the electrode. It is necessary to insulate the operator from such metal objects. e. Earthing of the metal part to be cut : When the part is not earthed - due to electrical safety reasons or because of its size and its location (e.g. ship hulls or metallic building structures), the earthing of the part can, in some cases but 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 direct connection, it is appropriate for the connection to be made with a capacitor selected according to national regulations. f. Protection and shielding: The selective protection and shielding of other cables and devices in the area can reduce perturbation issues. The protection of the entire cutting area can be considered for specic situations. TRANSPORT AND TRANSIT OF THE CUTTING MACHINE The machine is equipped with two handles to facilitate transport, which requires two people. Be careful not to underestimate the weight of the machine. The handle cannot be used to lift the product. Do not use the cable or torch to move the machine. The cutting equipment must be moved in an upright position. Do not place/carry the unit over people or objects. EQUIPMENT INSTALLATION

• Put the machine on the oor (maximum incline of 10°)

• Provide an adequate area to ventilate the machine and access the controls.

• This equipment must be used and stored in a place protected from dust, acid, gas or any other corrosive substance. The equipment protection is rated IP23 meaning that: - sensitive parts of the equipment are protected from objects with a diam >12.5 mm and, - it is protected again rainfall with a 60° vertical incline. The equipment can be used outside in accordance with the IP23 protection certication. Power cables, extension leads and welding cables must be fully uncoiled to prevent overheating. The manufacturer does not accept any liability in relation to damages caused to objects or harm caused to persons as the result of incorrect and/or dangerous use of the machine.21 NEOCUT 105 / 125

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 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 to prevent danger.• Ensure the vents of the device are not blocked to allow adequate air circulation.• Check that the torch does not have any cracks or exposed wires.• Check that the consumables are installed properly and not worn.Air lter maintenance :Purge of the lter tank :• Unplug the air supply.• Loosen the valve in the lower part of the lter tank by turning it anticlockwise.• Push the tap upwards to drain the water from the tank.• Tighten the valve at the bottom of the lter tank by turning it clockwise.Removing the lter element :• Disconnect the air supply.• Take hold of the tank and unscrew it from the body by turning it anticlockwise.• The lter element (white) can be blown out or replaced depending on its condition.Reassembling the lter element :• Put the lter element back in the tank, check the presence of the O-ring in the upper part.• Screw the tank back onto the body by turning it clockwise.

INSTALLATION – PRODUCT OPERATION

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.

DESCRIPTION NEOCUT is a three-phase Plasma cutting & gouging machine, it will allow:- Cutting on all metal types- Gouging on all metal types- Marking on all metal typesThese 3 processes require the use of appropriate consumables as well as compressed air or nitrogen. EQUIPMENT DESCRIPTION (FIG. 1 - PAGE 2) 1- Display screen 7- Transport handles.2- Adjustment knob 8- Replacement for pneumatic connector3- Earth clamp connection socket 9- Power supply cable

• The NEOCUT 105 is supplied with a 32A plug of type EN 60309-1.

• The NEOCUT 125 is supplied without plug, it is recommended to use a 63A plug of type EN 60309-1. These current sources should only be used on a four-wire, three-phase 400V (50-60 Hz) electrical installation with a neutral connected to earth.

• The eective absorbed current (I1e) is indicated on the device, for maximum operating conditions. Check that the power supply and its protections (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 machine is designed to work on a 400V +/- 15% power supply. If the input voltage is below 340Ve or above 460Ve, the machine goes into protection and the screen displays an error code.

• Power up the machine by setting the main on / o switch (FIG 1-10) to I position, and stop it by setting it on the 0 position. Warning! Never disconnect the power supply while the machine is operating.

CONNECTION TO A GENERATOR

The machine can work with generators as long as the auxiliary power matches these requirements: - The voltage must be AC, always be greater than 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 many generators generate high voltage peaks that can damage these machines.

USE OF EXTENSION LEADS

All extension leads must have an adequate size and section, relative to the voltage of the machine. Use an extension lead that complies with national safety regulations. Voltage input Extension lead section (<45m) NEOCUT 105 400 V 4 mm² NEOCUT 125 6 mm² AIR SUPPLY The air supply can come from a compressor or high-pressure bottles. A high-pressure manometer must be used on any type of air supply and must be able to transport the gas to the plasma cutter. These machines come with an integrated air lter (5μm), but an extra ltering system can be necessary depending on the quality of the air supply (optional impurities lter, ref. 039728). If the supplied air is of low quality, the cutting speed is reduced, the cutting quality deteriorates, the maximum cutting capacity decreases and the life cycle of the consumables is reduced. For best performance, the compressed air must comply with the standard ISO8573-1, class 1.2.2. The maximum steam point must be - 40 °C. The maximum quantity of oil (aerosol, liquid and steam) must be 0.1 mg/m3. Connect the gas supply to the power source using an inert gas pipe with an internal diameter of 9.5 mm and a quick release connector. The pressure must not exceed 9 bars, or the lter tank could explode. The recommended input pressure during air circulation is 5 to 9 bars with a minimum debit of 305 L/min.

CHOICE OF CONSUMABLES

• Manual cutting with torch MT 125 (6 m : ref. 039506, 12 m : ref. 039513) :23 NEOCUT 105 / 125

In order to obtain the expected performance and to guarantee a long lifetime for the consumables, make sure the current is set in accordance with the value indicated on the consumable (e.g. 45 A = 45 amps). Adjustment is simply done using the dial on the main screen.

AIR PRESSURE ADJUSTMENT

The NEOCUT is equipped with an electronicallycontrolled pressure regulator, the pressure is adjusted via the HMI (see following pages). In order to obtain optimal performance and service life of the consumables, it is very important : - To dene the right torch length - To use the adapted mode for the chosen consumables - To use the appropriate current for the chosen consumables - Leave the pressure setting on «auto». It is recommended to check that the parameters entered on the HMI are in line with the actual conguration, especially in the case of: - Connection point or pneumatic installation changes - Torch length change - Consumable type change - Doubt. It is possible to check the pneumatic circuit using the «air test» function, this allows, among other things, to check whether the pressure supplied by the compressor is sucient (see following pages).24 NEOCUT 105 / 125

Cutting / cutting with locked triggerUse one of these two modes to perform your cutting work on solid sheet metal.Pull the trigger to create the arc, and release it to stop or «unlock» (the arc stops by itself). For long cuts it is possible to use the locked trigger mode, in which case the trigger can be released during cutting. This mode prevents fatigue and keeps your hand a little further away from the cutting area.Gouging / gouging with locked triggerUse one of these two modes to perform your gouging work.Pull the trigger to create the arc, and release it to stop or «unlock» (the arc stops by itself). For long cuts it is possible to use the locked trigger mode, in which case the trigger can be released during cutting. This mode prevents fatigue and keeps your hand a little further away from the cutting area.Cutting of perforated metal sheetsUse this mode to perform cutting work on perforated metal sheets that require repetitive cutting stops / restarts. This is a cutting mode where the arc recharges itself as long as the trigger is held down. This mode is more comfortable to use, as it avoids constant pull and release of the trigger.Marking outThis mode, compatible with all cutting consumables, operates at low current and allows surface marking of sheet metal. Particularly useful for automated cutting to record for example references, bundle numbers... this mode is also accessible with a manual torch.

At rst startup, the machine will ask you to congure the following parameters:

It is a low power arc generated between the electrode and the nozzle and it allows the arc to start on the piece of metal to be cut. 2- When the pilot-arc touches the plate, the plasma cutter detects the start. The arc then ows between the electrode and the plate, and the machine increases the current up to the value set by the operator. 3- At the end of cutting (trigger release or unblocking), the arc stops, the air continues to come out for several dozens of seconds to cool the torch and consumables down.DISPLAYED WHILE CUTTING5.0 bar 105A 105A

Pull the trigger of the torch to prime the arc until the torch has completely pass through the part.

Once the cutting has started, drag the pad slightly on the metal sheet to continue cutting. Try to maintain a regular rhythm. START CUTTING INSIDE THE METAL SHEET:

With the earth clamp attached to the metal piece, maintain the torch at an angle of roughly 30° to the piece.

Press the torch trigger to start the arc while maintaining an angle of 30° to the part. Slowly rotate the torch towards a perpendicular position (90°).

Immobilise the torch while keeping the trigger pressed. If the sparks come from below the metal piece, the arc has cut the material.

Once the cutting has started, drag the pad slightly on the metal sheet to continue cutting. Try to maintain a regular rhythm. GOUGING:

With the earth clamp fastened to the part, keep for torch at a 45° angle to the piece, while maintaining the special gouging shield roughly 2mm away from the part before starting the torch.30 NEOCUT 105 / 125

Press the torch trigger before starting the arc while maintaining it at an angle of 45° to the piece while cutting through the groove Push the plasma arc in the direction you wish to cut. The distance between the torch shield and the melted metal should be as little as possible in order to avoid premature wear of the consumables or damage to the torch. Speed Angle Torch-part distance GROOVE SHAPEYou may modify the prole of the groove by adjusting the speed, the angle or the distance of the torch on the metal piece, or the power output on the machine.
