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 you 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 nor 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).
• 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 support or trolley.
• Do not weld in areas where grease or paint are stored.
• 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.
• 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 in.

CEM CLASSIFIED MATERIAL

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 does not comply with IEC 61000-3-12 and is intended to be connected to private low-voltage systems interfacing with the public supply only at the medium- or high-voltage level. On a public low- voltage power grid, it is the responsibility of the installer or user of the device to ensure, by checking with the operator of the distribution network, which device can be connected. This equipment complies with the IEC 61000-3-11 standard.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 the 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.

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 cable, 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.

•  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 shoud 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.

TRANSPORT AND TRANSIT OF THE WELDING MACHINE

The machine is fitted with handle(s) to facilitate transportation. Be careful not to underestimate the machine’s weight. The handle(s) cannot be used for slinging. Do not use cables or 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. The removal of the wire reel from the machine is recommended before undertaking any lifting operation.Stray welding currents/voltages may destroy earth conductors, damage electrical equipment or cause components to warm up which may cause a fire.

•  All welding connections must be firmly secured, check regularly !
•  Check that the metal piece fixation is strong and without any electrical problems!
•  Attach or hang all the electrically conductive elements, such as the trolley and slinging equipment, in order to insulate them
•  Do not place any electrical equipment, such as drills or grinders, on top of the welding machine without insulating them!
•  Always place welding torches or electrode holders on an insulated surface when they’re not in use !

EQUIPMENT INSTALLATION

•  Put the machine on the floor (maximum incline of 10°).
•  Ensure the work area has sufficient ventilation for welding, and that there is easy access to the control panel.
•  The machine must not be used in an area with conductive metal dust.
•  The machine must be placed in a sheltered area away from rain or direct sunlight.
•  The machine protection level is IP21, which means :
•  Protection against access to dangerous parts from solid bodies of a ≥12.5mm diameter and,
•  Protection against vertically falling drops.
• 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 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.

SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE)
Set the voltage output and the wire speed according to the thickness of the weld piece, following the instructions/recommendations printed on the side of the machine. The EASYMIG can weld Steel wire 0.6/0.8mm, and Stainless Steel of 0.8mm. The machine is fitted with Ø 0.8mm Steel or Stainless Steel rollers. The contact tube, the groove of the roller and the sleeve of the torch are all compatible with 0.8mm wire. Should you wish to weld 0,6 wire, use a torch of a maximum of 3m long. The contact tip must be changed (fig IV-D) as well as the wire feeder’s roller must be replaced by an optional reference (042339 / 039483) with a 0.6 diameter groove. In this case, the position in such a way to observe 0.6. For use with Steel, the gas requirement is argon + CO2. (Ar+CO2). The proportion of CO2 required will vary depending on the use. For Stainless Steel, use the combination of 2% CO2 For specific gas requirements, please contact your gas distributor. The gas flow in steel is between 8 and 12 Litres/minute depending on the environment. Maximum gas pressure: 0.5 MPa (5 bars).

SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE)
Set the voltage output and the wire speed according to the thickness of the weld piece, following the instructions/recommendations printed on the side of the machine. The EASYMIG 140 and 150 can be equipped to weld with aluminum wire Ø 0,8 or 1,0 (fig II-B). The Easy Mig 110 and 130 are delivered equipped for welding Aluminium of Ø 0.8mm (Occasional and non-intensive). In this case the wire used should be stiff to facilitate wire feeding. For use with aluminum, the gas requirement is pure argon (Ar). For the specific gas requirements please contact your distributor. The gas flow in Aluminium is between 20 and 30 Litres/minute depending on the environment, and the experience of the welder. Maximum gas pressure: 0.5 MPa (5 bars). Below are the differences between welding with Steel and Aluminium :

•  Specific rollers are needed for welding with Aluminium.
•  Adjust the pressure of the drive rolls to prevent the wire from being crushed.
•  Only use a capillary tube for welding with Steel or Stainless Steel.
•  Use a special Aluminium Torch with a Teflon sheath to reduce friction.
• DO NOT cut the sheath close to the joint, it is used to guide the wire from the rollers.
•  Contact Tube: Use a special aluminum contact tube specific to the diameter of wire being used.

GASLESS WIRE WELDING
Set the voltage output and the wire speed according to the thickness of the weld piece, following the instructions/recommendations printed on the side of the machine.
The EASYMIG can weld gasless wire up to 0.9mm, if the polarity is reversed respecting a maximum pressure of 5Nm. For parameters of use, please refer to the instructions indicated on page 67. Welding gasless wire with a standard nozzle can lead to overheating and deterioration of the torch. It is recommended to use a “No Gas” nozzle (ref. 041868), or remove the genuine nozzle

ELECTRODE WELDING

• The reverse polarity cable must be disconnected in MMA (stick welding) mode in order to connect the electrode holder and earth clamp. Connect the electrode holder and earth clamp as indicated on the electrode packaging.
•  Respect the basic rules of welding.
•  This device has 1 feature specific to Inverter machines :
•  Anti-Sticking: Enables easy removal of the electrode from the metal. The anti-sticking feature, after its start, requires approximately a 3 seconds delay before resuming normal welding operations.

SETTINGS PANEL

Advice
The wire speed adjustment is often determined « by the noise »: the arc must be stable and have a low crackling. If the speed is too low, the arc is not continuous. If the speed is too high, the arc crackles and the wire pushes back the torch.

PROCESS OF REELS AND TORCHES ASSEMBLY

•  Remove the contact tube and its support (fig D), and the nozzle (fig E) from the torch.

• Fig A :  Position the wire reel on the reel support :

•  Adjust the reel brake (1) to avoid reel movement tangling the wire when welding stops. Be careful not to tighten too much. EASYMIG 150: For a 200mm wire reel tighten the reel to the maximum.

• The adaptor (4) is only to be used for a 200mm reel. Fig B : The drive rollers included have 2 grooves (0,8 and 0,9). For 0.8mm steel wire, use the V-shaped groove. For flux cored wire, remove and reverse the roller to use the 0.9mm groove.

• For 0.8mm aluminum wire, remove and replace the roll with a model specifically designed for aluminum with a U-shaped groove (not included).
  Fig C : To select the adjustment of the drive rollers.

•  Loosen the drive roller knob (3) as far as possible and insert the wire, tighten the knob again slightly.

•  Start the motor by pressing the trigger of the torch.

•  Tighten the knob whilst pressing the trigger until the wire starts to move.
  Nb: When welding with Aluminium, use the minimum possible pressure to avoid crushing the wire

•  Leave about 5cm of wire out of the torch, then put the contact tube (fig. D), and the nozzle (fig. E) adapted to the wire to be used at the extremity.

GAS COUPLING

•  Connect a pressure regulator to the gas bottle. Connect the welding machine (fig. F) using the pipes supplied, and place the two clamps to avoid leakages.
•  Set the gas flow by adjusting the dial located on the pressure regulator.
• NB : to help facilitate the adjustment of the gas flow, operate the drive rollers by pressing the trigger of the torch (ensure that the drive roller is completely loose so the wire is not fed through).
  This procedure does not apply to «Gasless» welding mode.

DUTY CYCLE & WELDING ENVIRONMENT IN USE

• The machine has a “constant output” (constant voltage) in MIG/MAG mode; and a “dropping output” (constant current) in MMA mode. The duty cycles following the standard EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below:
