PROTECTION OF THE INDIVIDUALS

Arc welding can be dangerous and can cause serious injury or even death. Welding exposes the user to dangerous heat, arc rays, electromagnetic fields, the risk of electric shock, noise, and gas fumes. People wearing pacemakers are advised to consult a doctor before using the welding machine. To protect oneself as well as others, ensure the following safety precautions are taken:

• In order to protect you from burns and radiation, wear clothing without turn-ups or cuffs. These clothes must be insulating, dry, fireproof, in good condition, and cover the whole body.
• Wear protective gloves which guarantee electrical and thermal insulation.
• Use sufficient welding 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 fireproof welding curtains to protect the area against arc rays, weld spatter, and sparks. Inform the people around the working area to never look at the arc or the molten metal, and to wear protective clothing.
• Ensure ear protection is worn by the operator if the work exceeds the authorized noise limit (the same applies to any person 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 caused due to non-compliance with the safety precautions.
• Parts that have just been welded will be hot and may cause burns when touched. When servicing the torch or electrode holder, make sure that it is cold enough by waiting at least 10 minutes before doing so. 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 the protection of the goods and the safety of people.

WELDING FUMES AND GAS

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 insufficient 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 support or trolley. Do not weld in areas where grease or paint are stored

FIRE AND EXPLOSION RISKS

Protect the entire welding area. Compressed gas containers and other inflammable material must be moved to a minimum safe distance of 11 meters. A fire extinguisher must be readily available. Be careful of spatter and sparks, even through cracks. It can be the source of a fire or an explosion.
Keep people, flammable 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 inflammable or explosive materials (oil, petrol, gas…). Grinding operations should not be directed towards the device itself, the power supply or any flammable materials.

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 qualified 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.

CLASSIFICATION

This equipment is Class B. This equipment complies with the IEC 61000-3-12 standard. This equipment complies with the IEC 61000-3-11 standard.

RECOMMENDATIONS TO ASSES THE 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 fitting input filters. In all cases, electromagnetic interferences must be reduced until they are no longer bothersome.

Welding area assessment

Ce 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:

• the presence of other power cables (power supply cables, telephone cables, command cables, etc…)above, below, and on the sides of the arc welding machine.
• television transmitters and receivers
• computers and other hardware;
• critical safety equipment such as industrial machine protections;
• the health and safety of the people in the area such as people with pacemakers or hearing aids;
• calibration and measuring equipment
• The isolation of the equipment from other machinery. The user will have to make sure that the devices and equipment that are in the same room are compatible with each other. This may require extra precautions;
• 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 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.

Welding area assessment

Besides the welding area, the assessment of the arc welding systems installation itself can be used to identify and resolve cases of disturbances. The assessment of emissions must include in situ measurements as specified in Article 10 of CISPR 11: 2009. In situ measurements can also be used to confirm the effectiveness of mitigation measures.

RECOMMENDATION ON METHODS OF ELECTROMAGNETIC EMISSIONS REDUCTION

• 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 filtering of the power supply 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.
• Maintenance of the arc welding equipment: The arc welding machine should 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 modified 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.
• Welding cables: Cables must be as short as possible, close to each other, and close to the ground, if not on the ground.
• Electrical bonding : consideration should 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.
• 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.
• 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 specific situations.

TRANSPORTATION OF THE MACHINE

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