• Create a natural or artificial ventilation system in the work area.
• Use a suitable fume extraction system where welding and cutting works are being carried out. If necessary, install a system that can expel fumes and gases accumulated in the entire workshop. Use a suitable filtration system to avoid polluting the environment during discharge.
• If you are working in narrow and confined spaces or if you are welding lead, beryllium, cadmium, zinc, coated or painted materials, use masks that provide fresh air in addition to the above precautions.
• If the gas tanks are grouped in a separate zone, ensure that they are well ventilated, keep the main valves closed when gas cylinders are not in use, pay attention to possible gas leaks.
• Shielding gases such as argon are denser than air and can be inhaled instead of air if used in confined spaces. This is dangerous for your health as well.
• Do not perform welding operations in the presence of chlorinated hydrocarbon vapors released during lubrication or painting operations.
---|---

ArcLight May Damage Your Eyes and Skin

• Use a suitable protective mask and glass filter (4 to 13 according to EN 379) suitable for that to protect your eyes and face.
• Protect other naked parts of your body (arms, neck, ears, etc.) with suitable protective clothing from these rays.
• Enclose your work area with flame-resistant folding screens and hang warning signs at eye level so that people around you will not sustain injuries from arc rays and hot metals.
• This machine is not used for heating of icebound pipes. This operation performed with the welding machine causes an explosion, fire or damage to your installation.

Sparks and Spattering Particles  May Get Into Eyes and Cause Damage

• Performing works such as welding, surface grinding, and brushing cause sparks and metal particles to splatter. Wear approved protective work goggles which have edge  guards under the welding masks to prevent sustaining possible injuries

Hot Parts May Cause
Severe Burns

• Do not touch the hot parts with bare hands.
• Wait until the time required for the machine to cool down before working on its parts.
• If you need to hold hot parts, use suitable tools, welding gloves with high-level thermal insulation and fire-resistant clothes.

Noise May Cause

• The noise generated by some equipment and operations may damage your hearing ability.
• Wear approved personal ear protective equipment if the noise level is high.

Welding Wires Can Cause Injuries

• Do not point the torch towards any part of the body, other persons, or any metal while unwrapping the welding wire.
• When welding wire is run manually from the roller, especially in thin diameters the wire can slip out of your hand, like a spring or can cause damage to you or other people around, therefore you must protect your eyes and face while working on this.

Welding Operations
May Cause Fire and Explosion

• Never perform welding work in places near flammable materials. There may be fire or explosions.
• Before starting the welding work, remove these materials from the environment or cover them with protective covers to prevent combustions and flaring.
• National and international special rules apply in these areas.

| • Do not apply welding or cutting operations into completely closed tanks or pipes.
• Before welding to tanks and closed containers, open them, completely empty them, and clean them.
Pay the greatest attention possible to the welding operations you will perform in such places.
• Do not weld in tanks and pipes which might have previously contained substances that may cause explosions, fires or other reactions.
• Welding equipment heats up. For this reason, do not place it on surfaces that could easily burn or be damaged!
---|---
| • Welding sparks can cause a fire. For this reason, keep materials such as fire extinguishers tubes, water, and sand in easily accessible places.
• Use holding valves, gas regulators, and valves on flammable, explosive and compressed gas circuits.
Make sure that they are periodically inspected and pay attention that they run reliably.
---|---

Maintenance Work
Performed by Unauthorized
Persons To Machines and Apparatus May Cause Injuries

• Electrical equipment should not be repaired by unauthorized persons. Errors that occurred if failed to do so may result in serious injury or death when using the equipment.
• The gas circuit elements operate under pressure; explosions may occur as a result of services provided by unauthorized persons, and users may sustain serious injuries.
• It is recommended to perform technical maintenance of the machine and its auxiliary units at least once a year.

Welding In Small Sized and Confined Spaces

• In small-sized and confined spaces, absolutely make sure to perform welding and cutting operations, accompanied by another person.
• Avoid performing welding and cutting operations in such enclosed areas as much as possible.

Failure To Take
Precautions During
Transport May Cause
Accidents

• Take all necessary precautions when moving the machine. The areas where the machine is to be transported, the parts to be used in transportation and the physical conditions and health of the person carrying out the transportation works should be suitable for the transportation process.
• Some machines are extremely heavy; therefore, make sure that the necessary environmental safety measures are taken when changing their places.
• If the welding machine is to be used on a platform, it must be checked that this platform has suitable load-bearing limits.
• If it is to be transported by means of a haulage vehicle (transport trolley, forklift, etc.), make sure of the durableness of the vehicle, and the connection points (carrying suspenders, straps, bolts, nuts, wheels, etc.) that connect the machine to this vehicle.
• If the machine will be carried manually, make sure the durability of the machine apparatuses (carrying suspenders, straps, etc.) and connections.
• Observe the International Labor Organization’s rules on carriage weights and the transport regulations in force in your country in order to ensure the necessary transport conditions.
• Always use handles or carrying rings when relocating the power-supply sources.
• Never pull from torches, cables, or hoses. Be absolutely sure to carry gas cylinders separately.
• Remove all interconnections before transporting the welding and cutting equipment, each being separate, lift and transport small ones using their handles, and the big ones from their handling rings or by using appropriate haulage equipment, such as forklifts.

Falling Parts May Cause Injuries
Improper positioning of the power-supply sources or other equipment can cause serious injury to persons and physical damage to other objects.

• Place your machine on the floor and platforms with a maximum tilt of 10° so that it does not fall or tip over. Choose places that do not interfere with the flow of materials, where there is no risk of tripping over cables and hoses; yet, large, easily ventilatable, dust-free areas.
• To prevent gas cylinders from tipping over, on machines with a gas platform suitable for the tanks, fix the tanks onto the platform; in stationary usage applications, fix them to the wall with a chain in a way that they would not tip over for sure.
• Allow operators to easily access settings and connections on the machine.

Excessive Use Of The Machine Causes Overheating

• This device is in group 2, class A in EMC tests according to TS EN 55011 standard.

• This class A device is not intended for use in residential areas where electrical power is supplied from a low-voltage power supply. There may be potential difficulties in providing electromagnetic compatibility due to radio frequency interference transmitted and emitted in such places.
  This device is not compliant with IEC 61000 -3-12. In case if it is desired to be connected to the low voltage network used in the home, the installer to make the electrical connection or the person who will use the machine must be aware that the machine has been connected in such a manner; in this case the responsibility belongs to the user.

• Make sure that the work area complies with electromagnetic compatibility (EMC). Electromagnetic interferences during welding or cutting operations may cause undesired effects on your electronic devices and network, and the effects of these interferences that may occur during these operations are under the responsibility of the user.

• If there is any interference, to ensure compliance; extra measures may be taken, such as the use of short cables, use of shielded (armored) cables, transportation of the welding machine to another location, removal of cables from the affected device, and/or area, use of filters or taking the work area under protection in terms of EMC.

• To avoid possible EMC damage, make sure to perform your welding operations as far away from your sensitive electronic devices as possible (100m).

• Ensure that your welding and/or cutting machine has been installed and situated in its place according to the user manual.

Evaluation Of Electromagnetic
According to article 5.2 of IEC 60974-9;
Suitability Of The Work Area

Before installing the welding and cutting equipment, the person in charge of the operation and/or the user must conduct an inspection of possible electromagnetic interference in the environment. The aspects indicated below has to be taken into consideration;
a) Other supply cables, control cables, signal and telephone cables, above and below the welding machine and its equipment,
b) Radio and television transmitters and receivers,
c) Computer and other control hardware,
d) Critical safety equipment, e.g. protection of industrial equipment,
e) Medical apparatus for people in the vicinity, e.g. pacemakers and hearing aids,
f) Equipment used for measuring or calibration,
g) Immunity of other equipment in the environment. The user must ensure that the other equipment in use in the environment is compatible. This may require additional protection measures.
h) Considering the time during which the welding operations or other activities take place during the day, the boundaries of the investigation area can be expanded according to the size of the building, the structure of the building, and other activities that are being performed in the building.
In addition to the evaluation of the field, evaluation of device installations may also be necessary for solving the interfering effect.
In case if deemed necessary, on-site measurements can also be used to confirm the efficiency of mitigation measures. (Source: IEC 60974-9).

Electromagnetic Interference
Reduction Methods

• The appliance must be connected to the electricity supply in the recommended manner by a competent person. If interference occurs, additional measures may be applied, such as filtering the network. The supply of the fixed-mounted arc welding equipment must be made in a metal tube or with an equivalent shielded cable. The housing of the power supply must be connected and good electrical contact between these two structures has to be provided.
• The recommended routine maintenance of the appliance must be carried out. All covers on the body of the machine must be closed and/or locked when the device is in use. Any changes, other than the standard settings without the written approval of the manufacturer, cannot be modified on the appliance. Otherwise, the user is responsible for any consequences that may possibly occur.
• Welding cables should be kept as short as possible. They must move along the floor of the work area, in a side-by-side manner. Welding cables should not be wound in any way.
• A magnetic field is generated on the machine during welding. This may cause the machine to pull metal parts onto itself. To avoid this attraction, make sure that the metal materials are at a safe distance or fixed. The operator must be insulated from all these interconnected metal materials.
• In cases where the workpiece cannot be connected to the ground due to electrical safety, or because of its size and position (for example, in building marine vessel bodies or in steel construction manufacturing), a connection between the workpiece and the grounding may reduce emissions in some cases, it should be kept in mind that grounding of the workpiece may cause users to sustain injuries or other electrical equipment in the environment to break down. In cases where necessary, the workpiece and the grounding connection can be made as a direct connection, but in some countries where a direct connection is not permissible, the connection can be established using appropriate capacity elements in accordance with local regulations and ordinances.
• Screening and shielding of other devices and cables in the work area can prevent aliasing effects. Screening of the entire welding area can be evaluated for some specific applications.

Arc Welding May Cause Electromagnetic Field (EMF)

The electrical current passing through any conductor generates zonal electric and magnetic fields (EMF).
All welders must follow the following procedures to minimize the risk of exposure to EMF from the welding circuit;

• In the name of reducing the magnetic field, the welding cables must be assembled and secured as far as possible with the joining materials (tape, cable ties etc.).
• The welder’s/worker’s body and head should be kept as far away from the welding machine and cables as possible,
• Welding and electric cables should not be wrapped around the body of the machine in any way,
•  The body of the machine should not get caught between the welding cables. The source cables must be kept away from the body of the machine, both being placed side by  side,
•  The return cable must be connected to the workpiece as close as possible to the welded area,
• The welding machine should not rest against the power unit, ensconce on it and not work too close to it,
•  Welding work should not be performed when carrying the welding wire supply unit or welding power unit.

EMF may also disrupt the operation of medical implants (materials placed inside the body), such as pacemakers. Protective measures should be taken for people who carry medical implants. For example, access limitations may be imposed for passers-by, or individual risk assessments may be conducted for welders. Risk assessment should be conducted and recommendations should be made by a medical professional for users who carry medical implants.

Protection

• Do not expose the machine to rain, prevent the machine from splashing water or pressurized steam.

Energy Efficiency

• Choose the welding method and welding machine for the welding work you are to perform.
• Select the welding current and/or voltage to match the material and thickness you are going to weld.
•  If you have to wait for a long time before you start your welding work, turn off the machine after the fan has cooled it down. Our machines (our products) with smart fan control will turn off on their own.

Waste Procedure

• This device is not domestic waste. It must be directed to recycling within the framework of the
  European Union directive and national laws.

• Obtain information from your dealer and authorized persons about the waste management of your used machines.
