INDIVIDUAL PROTECTIONS AND OTHERS

Arc welding can be dangerous and can cause serious and even fatal injuries. Welding exposes the user to dangerous heat, arc rays, electromagnetic fields, noise, gas fumes, and electrical shocks. People wearing pacemakers are advised to consult with their doctor before using this device.

To protect oneself as well as others, ensure the following safety precautions are taken:

• In order to protect yourself from burns and radiation, wear clothing without cuffs. These clothes must be insulated, dry, fireproof and 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. Do not operate whilst wearing contact lenses.

• It may be necessary to install fireproof welding curtains to protect the area against arc rays, weld spatters 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 authorised noise limit (the same applies to any person in the welding area).

• Stay away from moving parts (e.g. engine, fan…) with hands, hair, clothes, etc.
  Never remove the safety covers from the cooling unit when the machine is plugged in – The manufacturer is not responsible for any accident or injury that happens as a result of not following these safety precautions.

• The pieces that have just been welded are hot and may cause burns when manipulated. During maintenance work on the torch or the electrode holder, you should make sure it’s cold enough and wait at least 10 minutes before any intervention. The cooling unit must be on when using a water-cooled torch in order to ensure that the liquid does not cause any burns. ALWAYS ensure the working area is left as safe and secure as possible to prevent damage or accidents.

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 a support or trolley. Do not weld in areas where grease or paint is stored.

FIRE AND EXPLOSIONS 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 toward the device itself, the power supply or any flammable materials.

GAS BOTTLE
Gas leaking from the cylinder can lead to suffocation if present in high concentrations around the work area.

Transport must be done safely: Cylinders closed and product off. Always keep cylinders in an upright position securely chained to a fixed support or trolley. Close the bottle after any welding operation. Be wary of temperature changes or exposure to sunlight. Cylinders should be located away from areas where they may be struck or subjected to physical damage. Always keep gas bottles at a safe distance from arc welding or cutting operations, and any source of heat, sparks or flames. Be careful when opening the valve on the gas bottle, it is necessary to remove the tip of the valve and make sure the gas meets your welding requirements.

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.

EMC CLASSIFICATION
These Class A devices are not intended to be used on a residential site where the electric current is supplied by the public network, with a low-voltage power supply. There may be potential difficulties in ensuring electromagnetic compatibility on these sites, because of the interferences, as well as radio frequencies.

This equipment complies with the IEC 61000-3-12 standard.

ELECTROMAGNETIC INTERFERENCES
The electric currents flowing through a conductor cause electrical and magnetic fields (EMF). The welding current generates an EMF field around the welding circuit and the welding equipment.

The EMF fields may disrupt some medical implants, such as pacemakers. Protection measures should be taken for people wearing medical implants. For example, access restrictions for passers-by or an individual risk evaluation for the welders.

All welders should take the following precautions in order to minimize exposure to electromagnetic fields (EMF) generated by the welding circuit:

• position the welding cables together – if possible, attach them;
• keep your head and torso as far as possible from the welding circuit;
• never enroll the cables around your body;
• never position your body between the welding cables. Hold both welding cables on the same side of your body;
• connect the earth clamp as close as possible to the area being welded;
• do not work too close to, do not lean, and do not sit on the welding machine
• do not weld when you’re carrying the welding machine or its wire feeder.

People wearing pacemakers are advised to consult their doctor before using this device. Exposure to electromagnetic fields while welding may have other health effects which are not yet known.

RECOMMENDATIONS TO ASSESS THE WELDING 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
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. 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 suplly 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 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 risk of 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.

TRANSPORT AND TRANSIT OF THE WELDING MACHINE
The machine is fitted with a handle to facilitate transportation. Be careful not to underestimate the machine’s weight. The handle cannot be used for slinging. Do not use cables or a torch to move the machine. The welding equipment must be moved in an upright position. Do not place/carry the unit over people or objects. Never lift the machine while there is a gas cylinder on the support shelf. A clear path is available when moving the item.

EQUIPMENT INSTALLATION

• Put the machine on the floor (maximum incline of 10°.)
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine protection level is IP23, which means:
  • Protection against access to dangerous parts from solid bodies of a ≥12.5mm diameter and,
  • Protection against the rain inclined at 60% towards the vertical.

These devices can be used outside in accordance with the IP23 protection index.

The power cables, extensions, and welding cables must be fully uncoiled to prevent overheating. The manufacturer does not incur any responsibility 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 qualified person. Annual maintenance is recommended.
• Ensure the machine is unplugged from the mains, and wait for two minutes before carrying out the maintenance work. DANGER High Voltage and Currents inside the machine.
• 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 qualified 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 qualified person.
• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
• Do not use this equipment to thaw pipes, to charge batteries, or to start any engine.

INSTALLATION PRODUCT OPERATION

Only qualified personnel authorized by the manufacturer should perform the installation of the welding equipment. During setup, the operator must ensure that the machine is disconnected from the mains. Connecting generators in series or in parallel is forbidden. It is recommended to use the welding cables supplied with the unit in order to obtain the optimum product settings.

EQUIPMENT DESCRIPTION

POWER SWITCH
The PROGYS FLEX 280A CEL is supplied without a plug and equipped with «Flexible voltage» technology and as such needs to be connected to an electrical earthed installation supplying between 110V and 480V single-phase or three-phase current (50-60Hz). This machine must only be used with a three- phase electricity supply system with four wires and one earthed neutral.

Connection schematic

WARNING! If connected via a single-phase plug, the unused wire must be insulated to make sure it never makes contact with the other ones.

The absorbed effective current (I1eff) is displayed on the machine, for optimal use. Check that the power supply used and its protection (fuse and/or circuit breaker) are compatible with the current required by the machine. In some countries, it may be necessary to change the plug to allow the use at maximum settings. The user has to make sure that the plug can be reached. The devices turn into protection mode if the power supply tension is below or above 15%. When this is the case, the screen displays an error code.

• Turn the main switch (5) to the «I» position to turn the machine on and to «0» to turn it off. The device is switched on by pressing the « » button. Attention! Never disconnect the power supply when the welding electrical distribution is in operation.

Fan:

• In MMA mode, the fan is always running.
• In TIG mode, the fan works only during welding, then stops after the machine has cooled down.

COATED ELECTRODE WELDING (MMA)

CONNECTIONS AND RECOMMENDATIONS

• Connect the cables, electrode holder, and earth clamp to the connectors,
• Follow the welding polarities and power recommendations indicated on the electrodes boxes,
• Remove the electrode from the electrode holder when the machine is not in use.
• The machine has 3 features exclusive to Inverters:
  • The Hot Start creates an overcurrent at the beginning of the welding.
  • The Arc Force creates an overcurrent that prevents the electrode from sticking to the weld pool.
  • The Anti-Sticking technology makes it easier to unstick the electrode from the metal.

MMA WELDING PROCESSES

MMA STANDARD
The MMA STANDARD mode is recommended for most applications. It can weld any type of electrode: rutile, basic, cellulosic… and on any materials: steel, stainless steel, cast iron.

Activating the MMA mode and setting the intensity:

• Select the MMA mode (2) using the switch (5).
• MMA blinks for 1 second every 5 seconds (display (1)).
• Set the desired intensity using the keys (4).
• The machine is ready to operate.

To set the Hot Start, follow these steps:

Recommendations:

• Low Hot start, for thin sheets
• High Hot start for difficult-to-weld metals (dirty or oxydised)

When the machine is in MMA Standard mode:

• Press shortly the switch (5).
• «HS» (Hot Start) blinks and a number is displayed. (display (1)).
• Set the desired percentage using the keys (4).
• The machine is ready to operate.

To set the Arc Force, follow these steps:

Advice:

The Arc Force is manually adjustable from 0 to 90% or a choice of the electrode is possible (Rutile, Basic or Cellulosic) by continuing the adjustment beyond 90%.

• Low Arc Force, for rutile and stainless steel electrodes
• High Arc Force, for basic, cast-iron, and cellulosic electrodes

When the machine is in MMA pulse mode:
