ANOMALIES, CAUSES, REMÈDES

CONDITIONS DE GARANTIE

These instructions must be read and fully understood before use. Do not carry out any alterations or maintenance work that is not directly specified in this manual.

The manufacturer shall not be liable for any damage to persons or property resulting from use not in accordance with the instructions in this manual. In the event of any problems or uncertainty, please consult a person qualified to deal with the unit correctly. Read the welding machine's instruction manual before using the wire feeder.

ENVIRONMENT

This equipment should only be used for welding operations performed within the limits indicated on the information panel and/or in this manual. These safety guidelines must be observed. In the event of improper or dangerous use, the manufacturer cannot be held responsible.

The equipment must be operated and stored in a location that is free of dust, acid, flammable gases or any other corrosive substances. Operate the machine in an open, or well-ventilated area.

Temperature range: Use between -10 and +40°C (+14 and +104°F). Store between -20 and +55°C (-4 and 131°F). Air humidity: Lower than or equal to 50% at 40°C (104°F). Lower than or equal to 90% at 20°C (68°F). Altitude: Up to 1,000 m above sea level (3280 feet).

PROTECTING YOURSELF AND OTHERS

Arc welding can be dangerous and cause serious injury or death.

Welding exposes people to a dangerous source of heat, light radiation from the arc, electromagnetic fields (caution to those using pacemakers) and risk of electrocution, as well as noise and fumes.

To protect yourself and others, please observe the following safety instructions:

To protect yourself from burns and radiation, wear clothing that does not have turn-ups, that is insulating, dry, flame-retardant and in good condition, and that covers the whole body.

Wear protective gloves which provide electrical and thermal insulation.

Use welding protection and/or a welding helmet with a sufficient level of protection (depending on the specific use). Protect your eyes during cleaning procedures. Contact lenses are strictly prohibited. It may be necessary to section off the welding area with fireproof curtains to protect the area from arc radiation and hot spatter. Inform people in the welding area not to stare at the arc rays or molten parts and to wear appropriate clothing for protection.

Wear noise-cancelling 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 protective covers from the cooling unit while the welding power source is switched on, the manufacturer cannot be held responsible in the event of an incident.

Newly welded parts are hot and can cause burns when handled. When maintenance work is carried out on the torch or electrode holder, ensure that it is sufficiently cold by waiting at least 10 minutes before carrying out any work. The cooling unit must be switched on when using a water-cooled torch to ensure that the liquid cannot cause burns.

It is important to ensure that the work area is safe before leaving it, to help protect both people and property.

WELDING FUMES AND GAS

The fumes, gases and dusts emitted by welding are harmful to health. Sufficient ventilation must be provided and an additional air supply may be required. An air-fed mask could be a solution in situations where there is inadequate ventilation. Check the extraction system performance against the relevant safety standards.

Caution: Welding in confined spaces requires safety monitoring from a safe distance. In addition, welding certain materials containing lead, cadmium, zinc or mercury, or even beryllium, can be particularly harmful, so degrease the parts before welding them.

Cylinders should be stored in open or well-ventilated areas. They should be stored in an upright position and kept on a stand or trolley. Welding should not be carried out near grease or paint.

RISK OF FIRES AND EXPLOSIONS

Fully shield the welding area, flammable materials should be kept at least 11 metres away.

Fire-fighting equipment should be kept close to wherever the welding activities are being undertaken.

Beware of hot material, spatter or sparks being projected, even through cracks, as these can be a source of fire or explosion.

Keep people, flammable objects and pressurised containers at a safe distance.

Welding in closed containers or tubes is to be avoided. If the containers or tubes are open, they must be emptied of all flammable or explosive materials (oil, fuel, gas residues, etc.).

Grinding work must not be directed towards the source of the welding current or towards any flammable materials.

GAS CYLINDERS

Gas escaping from cylinders can cause suffocation if there is too high a concentration of it in the welding area (ensure good ventilation).

The machine must be transported in complete safety: gas cylinders must be closed and the welding power source turned off. They should be stored upright and supported to limit the risk of falling.

Close the cylinder between uses. Beware of temperature variations and exposure to the sun.

The cylinder must not come into contact with flames, arcs, torches, earth clamps or any other sources of heat or ignition.

Be sure to keep it away from electrical and welding circuits. Never weld a pressurised cylinder.

When opening the cylinder valve, keep your head away from the valve and ensure that the gas being used is suitable for the welding process.

ELECTRICAL SAFETY

The electrical network used must be earthed. Use the recommended fuse size from the rating plate.

An electric shock, whether direct or indirect, can cause serious injury or death.

Never touch live parts connected to the live current, either inside or outside the power source casing unit (torches, clamps, cables, electrodes), as these items 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 the electrode holder and the earth clamp at the same time.

If cables or torches are damaged, they should be replaced by qualified and authorised personnel. Measure the cable cross-section according to the intended application. Always use dry and in-tact clothing to insulate yourself from the welding circuit. Always wear insulated footwear, in all working environments.

INSTALLATION OF THE REEL AND LOADING OF THE WIRE

Isolate the welder from the welding voltage!

Not all the different parts involved in the welding current can be protected against direct human contact. The welder must therefore avoid the risks by following the relevant safety regulations. Even contact with low current may take the operator by surprise and cause an accident..

- Make sure any protective clothing worn is dry and in good condition (rubber sole shoes / leather welding gloves without staples or rivets).

- Avoid direct contact with uninsulated sockets or plugs

- Always place the welding torch or electrode holder on an insulated support.

Risk of burning at the welding power connection!

If the connectors are not safely locked in place, the connectors and the cables can become hot and cause burns!

- Check the welding connectors daily and lock them in place if needed by turning them to the right.

Risk of electrocution!

If the weld is performed using different processes while the torch and the electrode holder are connected to material, a no-load voltage or welding voltage is applied to the circuits.

- Always isolate the torch and electrode holder when starting work, and during any stoppages/interruptions.

ELECTRO-MAGNETIC EMISSIONS

An electric current passing through any conductor produces localised electric and magnetic fields (EMF). The welding current produces an electromagnetic field around the welding circuit and the welding equipment.

Electromagnetic fields (EMFs) can interfere with some medical devices; pacemakers for example. Protective measures must be taken for people with medical implants. For example, restricted access for passers-by or an individual risk assessment for welders.

All welders should use the following guidelines to minimise exposure to the welding circuit's electromagnetic fields:

• position the welding cables together - securing them with a clamp if possible;
• position yourself (head and body) as far away from the welding circuit as possible;
• never wrap the welding cables around your body;
• do not position yourself in between the welding cables. Keep both welding cables on the same side of the body;
• connect the return cable to the workpiece, as close as possible to the welding area;
• do not work next to, sit on, or lean against the source of the welding current;
• do not weld while the current source or wire feeder is being carried.

Pacemaker users should consult a doctor before using this equipment.

Exposure to electromagnetic fields during welding may have other health effects that are not yet known.

TRANSPORT AND TRANSIT OF THE WIRE FEEDER

The wire feeder is equipped with a top handle for carrying by hand. Be careful not to underestimate the weight of the unit. The handle cannot be used to hang or attach the machine on something else.

Never lift the machine while there is a gas bottle on the support shelf. Their transportation requirements are different.

Do not carry the unit over people or objects.

The removal of the wire reel from the machine is recommended before undertaking any lifting operation.

SETTING UP THE EQUIPMENT

• Put the wire feeder on a floor with a maximum incline of 10^ .
• The product should be protected from driving rain and not be exposed to direct sunlight.
• The unit has an IP23 protection rating which means:
• the dangerous parts of the machine are protected against entry by objects greater than 12.5 mm and,
• protected against rain directed at a 60% angle from vertical.
  The equipment can be used outside in accordance with the IP23 protection certification.

The manufacturer assumes no responsibility for damage to persons or objects caused by improper and dangerous use of this equipment.

Power, extension and welding cables must be completely uncoiled in order to avoid overheating.

MAINTENANCE / RECOMMENDATIONS

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

• Ensure the wire feeder is disconnected from the welding machine, and wait for two minutes before carrying out maintenance work.

• Regularly remove the cover and blow out any dust. Take this opportunity to have the electrical connections checked by a qualified person, using an insulated tool.

• Regularly check the condition of the connection cable between the wire feeder and the machine. If found damaged, the interconnection cable must be replaced.

Warning! If handling equipment other than that recommended by the manufacturer is used during welding, provide insulation between the wire feeder casing and the handling equipment.

- The wire feeder must only be used with all hatches closed.

INSTALLATION - USING THE PRODUCT

Only experienced personnel, authorised by the manufacturer, may carry out the set-up of the machine. During set-up, ensure that the power source is unplugged from the mains. It is recommended to use the welding cables supplied with the unit in order to obtain the best possible product performance.

To install the wire, follow the steps below:

• Loosen the knob as far as it will go and lower it.
• Insert the wire, then close the winding motor and tighten the knob as indicated.
• Activate the motor on the trigger on the torch or on the manual wire inching button (III-7).

Notes:

• A liner that is too narrow can lead to feed issues and cause the motor to overheat.
• The torch connection must also be properly tightened to prevent it from overheating.
• Check that neither the wire nor the spool touches the mechanics of the unit, otherwise there is a risk of short-circuit.

RISK OF INJURY FROM MOVING COMPONENTS

Wire feeders have moving parts that can catch hands, hair, clothing or tools, and cause injury.

• Do not touch rotating, moving or driving parts of the machine.
• Ensure that the housing doors or protective covers remain closed during operation.
• Do not wear gloves when threading the filler wire or changing the wire spool.

SEMI-AUTOMATIC STEEL/STAINLESS STEEL WELDING (MAG MODE)

This machine can weld steel and stainless steel wire from ∅ 0.8 to 1.6 mm (I-A). The unit is supplied with ∅ 1.0/1.2 rollers for steel or stainless steel as standard. The contact tip, the grooved roller, and the torch liner are designed for this application.

For use on steel, a specific welding gas (Ar+CO2) is required. The amount of CO2 may vary depending on the type of gas used. For stainless steel, use a 2% CO2 mixture. When welding with pure CO2, it is necessary to connect a gas pre-heater to the gas cylinder. It is also possible to use a standard preheating module (36V) which can be connected to the 36V power socket located in the power source (available separately), located behind the side door. Please note that this 36V DC power supply is also compatible with 36V AC preheaters. If you have specific gas requirements, please contact your gas distributor. The gas flow rate for steel is between 8 and 15 litres per minute depending on the environment. To check the gas flow on the manometer without unspooling the filler wire, press and hold the button (III-7). This check should be done periodically to ensure the best possible welding performance.

SEMI-AUTOMATIC ALUMINIUM WELDING (MIG MODE)

The unit can weld aluminium wire from ∅ 0.8 to 1.6mm (I-B).

For use with aluminium, pure argon gas (Ar) is required. When it comes to choosing your gas, ask a gas distributor for advice. The gas flow rate for aluminium is between 15 and 20 l/min depending on the surrounding environment and the welder's experience.

The differences between steel and aluminium applications are as follows:

• Use specific rollers for aluminium welding.
• Apply minimum pressure to the rollers on the wire feed motor to avoid compressing the wire.
• Only use the capillary tube (for guiding the wire between the feed rollers and the EURO connector) for steel/stainless steel welding (I-B)
• Use a dedicated aluminium torch. This aluminium torch has a teflon liner to reduce friction. DO NOT cut away the coating at the tip of the connector! This coating is used to guide the wire from the rollers.
• Contact tips: use a SPECIAL aluminium contact tip that matches the wire diameter.

GASLESS SEMI-AUTOMATIC WELDING WITH FLUX-CORED WIRE

The equipment can weld gasless flux-cored wire from ∅ 0.9 to 1.6 mm. The original rollers must be replaced by specific gasless wire rollers (available as an optional extra). Welding flux-cored wire with a standard nozzle can lead to overheating and damage to the torch. Remove the original nozzle from your MIG-MAG torch. Gasless MIG/MAG welding generally requires negative polarity. In this situation, it is necessary to use an optional polarity reversal cable. See the power source manual for connection instructions.

*Les facteurs de marche sont réalisés selon la norme EN80974-1 à 40°C et sur un cycle de 10 min. Lors d'utilisation intensive (supérieur au facteur de marche) la protection thermique peut s'enciencher, dans ce cas, l'arc sé étent et le témoin) s'allume. Laissez l'appareil alimenté pour permettre son réfroidissement jusqu'à annulation de la protection. Pour ne pas endommager le dévidor, le facteur de marche de la source de courant de soudage doit toujours être inférieur a celui indiqué sur le dévidor.
*The duty cycles are measured according to standard EN80974-1 à 40°C and on a 10 min cycle. While under intensive use (> to duty cycle) the thermal protection can turn on, in that case, the arc switches off and the indicator switches on. Keep the machine's power supply on to enable cooling until thermal protection cancellation. To prevent damage to the wire feeder, the duty cycle of the welding current source should always be lower than that indicated on the wire feeder.
* Einschaltdauer gemäß EN60974-1 (10 Minuten - 40°C). Bei sehr intensivem Gebrauch (>Einschaltdauer); kann der Thermoschutz ausgelöst werden. In diesem Fall wird der Lichtbogen abgeschaltet und die entsprechende Warnung > erscheint auf der Anzeige. Das Gerät zum Abkühlen nicht ausschalten und laufen lassen bis das Gerät wieder bereit ist. Um die Drahtvorschübeinheit nicht zu beschädigen, muss die Einschaltdauer der Schweißstromquelle immer kleiner sein als die auf der Drahtvorschübeinheit angegebene Einschaltdauer.
Los ciclos de trabajo están realizados en acuerdo con la norma EN60974-1 a 40°C y sobre un ciclo de diez minutos. Durante un uso intensivo (superior al ciclo de trabajo), se puede activar la protección térmica. En este caso, el arcó se apaga y el indicador ¡se encende. Deje el aparato conectado para permitir que se entfite hasta que se anule la protección. Para evitar danos en el devanador, el ciclo de trabajo de la fuente de corriente de soldacura debe ser siempre inferior al indicado en el devanador.
