PROTECTION OF THE INDIVIDUALS

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 the other, ensure the following safety precautions are taken:

• In order to protect you from burns and radiations, 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 clothes.
• 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).
• 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 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…).mGrinding operations should not be directed towards 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

• 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.
• Provided that the impedance of the low-voltage public electrical network at the common coupling point is less than Zmax = 0.404 Ohms, this equipment complies with IEC 61000-3-11 and can be connected to public low-voltage electrical mains. It is the responsibility of the installer or user of the equipment to ensure, in consultation with the distribution network operator if necessary, that the network impedance complies with the impedance restrictions.
• 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.

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 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.

RECOMMANDATIONS 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
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:

• a) 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.
• b) television transmitters and receivers ;
• c) computers and other hardware;
• d) critical safety equipment such as industrial machine protections;
• e) the health and safety of the people in the area such as people with pacemakers or hearing aids;
• f) calibration and measuring equipment
• g) The isolation of the equipment from other machinery. The user will have to make sure that the devices and equipment’s that are in the same room are compatible with each other. This may require extra precautions;
• h) 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 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

• a. 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.
• b. 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.
• c. Welding cables: Cables must be as short as possible, close to each other and close to the ground, if not on the ground.
• d. 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.
• e. 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.
• f. 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 the cables or torch to move the machine. The welding equipment must be moved in an upright position.
Never lift the machine while there is a gas cylinder on the support shelf. A clear path is available when moving the item. Do not place/carry the unit over people or objects.

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 dusts.
•  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 welding current source to defrost pipes, recharge batteries/accumulators or start motors.

INSTALLATION – PRODUCT OPERATION
Only qualified personnel authorized by the manufacturer should perform the installation of the welding equipment. During the installation, the operator must ensure that the machine is disconnected from the mains. Connecting generators in serial 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.

Note: the sub-process selected by default at machine startup corresponds to the last sub-process used before the last sleep or shutdown.

**| Main incremental encoder**

As default, the incremental encoder allows the adjustment of the welding current.. It is also used to set the values of other para- meters which are then selected via the associated keys. Once the parameter setting has been completed, it is possible to press the key of the parameter that has just been set again so that the incremental encoder is again linked to the current setting. It is also possible to press another key related to another parameter to adjust it. If no action is performed on the HMI for 2 seconds, the incremental encoder is again linked to the welding current setting.

| « Pre-Gas « button

The Pre-Gas adjustment is done by pressing and releasing the Pre-Gas button and then activating the main incremental encoder. Pre-Gas value increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting has been made, it is possible to press and release the Pre-Gas button again to re-link the main incremental encoder to the current setting or to wait for 2 seconds. The setting step is 0.1 sec. The minimum value is 0 sec. and the maxi- mum value is 25 sec.

| « Post-Gas « button

The Post-Gas adjustment is done by pressing and releasing the Post-Gas button and then activating the main incremental encoder. Post-Gas value increases when the incremental encoder is operated clockwise and decreases when it is operated anti- clockwise. Once the setting has been made, it is possible to re-press and release the Pre-Gas pushbutton to re-link the main incremental encoder to the current setting or to wait 2 seconds. The setting step is 0.1 sec. The minimum value is 0 sec. and the maximum value is 25 sec. The default value is 6sec.

| «Up Slop» or current control button

The current ramp-up setting is done by pressing and releasing the current ramp-up button and then by activating the main incremental encoder. Current ramp-up value increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting has been made, it is possible to press and release the current ramp-up button again to re- link the main incremental encoder to the current setting or to wait for 2 seconds. The setting step is 0.1 sec. The minimum value is 0 sec. and the maximum value is 25 sec. The default value is 0sec. In MMA mode, the Hotstart is adjustable between 0 and 100% of the welding current in 5% steps. The default value is 40%.

| Potentiometer for setting the fading or «Downslope».

The «Downslope» potentiometer is used to adjust the value of the current fading (clockwise increment and counterclockwise decrement). The value is visible on the 7-segment display and remains displayed for 2 seconds if an action on the potentiometer is performed. The minimum value is 0 sec. and the maximum value is 20 sec.

| Cold current control button

When one of the 2 processes «TIG HF» or «TIG LIFT» is selected, the cold current setting button is used to adjust the cold current value only in the «PULSE» configuration. The value can be adjusted between 20% and 80% of the welding current. The incremental step is 1%. The default value is 30%.

In MMA mode, the Arc Force is indexed from -10 to +10 (-10 = no Arc Force / -9 to +10 = Arc Force setting possible). The default index value is 0.

WELDING WITH RUBBERED ELECTRODE (MMA MODE)

CONNECTIONS AND RECOMMENDATIONS

• Connect the cables, electrode holder and earth clamp in the connectors,
• Respect the welding polarities and intensities indicated on the electrodes boxes,
• Remove the electrode from the electrode holder when the machine is not in use.

The grey areas are not useful for this mode.

Adjustable values| 0 – 100%| -10 / +10 (indexé)

MMA Pulse
This MMA Pulse welding mode is suitable for applications in the vertical up position (PF). The pulse mode keeps the weld pool cold and eases the transfer of matter. Without the pulse mode, vertical-up welding requires a difficult «Christmas tree» shape triangular movement. With the MMA Pulsed mode, this movement is no longer required and a simple straight up movement is enough (depending on the thickness of the workpiece). If you wish to widen your weld pool, a simple lateral movement is enough (similar to standard welding). This process allows greater control during vertical-up welding. The pulse frequency is adjusted by pressing and releasing the «F(Hz)» button and then activating the main incremental encoder. Frequency value increases when the incremental encoder is operated clockwise and decreases when it is operated anti- clockwise. Once the setting has been made, it is possible to re-press and release the «F(Hz)» button to re-link the main incremental encoder to the current setting or to wait 2 seconds. This frequency ranges from 0.4Hz to 20Hz in Pulse MMA. The incrementation step depends on the frequency range:

MMA – Advanced menu
Anti sticking can be turned on or off, Hofstra time can be set in MMA and cold current settings in Pulse MMA.

• These advanced settings can be accessed by pressing the during 3 seconds until SET and UP are displayed.
• Once the button is released , use the knob to select «SET» from the dropdown menu and confirm by pressing the button.

TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG MODE)

CONNECTIONS AND RECOMMENDATIONS
Connect the earth clamp to the positive connector (+). Connect the torch to the negative plug (–), the trigger cable and the gas hose.
Ensure that the torch is equipped and ready to weld and that the consumables (Vise grip, ceramic gas nozzle, collet and collet body) are not worned out.

TIG WELDING PROCESSES

• TIG DC
  This welding mode in direct current (DC) is designed for ferrous metal such as steel, stainless steel or even copper and its alloys.

• TIG DC Pulse
  This pulsed current welding mode is a combination of high current pulses (I, welding pulse) and low current pulses (I_Cold, part cooling pulse). This pulse mode allows to assemble pieces while while keeping the machine cooler. The I welding current is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A. F(Hz) is set to 10Hz, the signal period will be 1/10Hz = 100ms. Every 100ms, a 100A pulse then a 50A pulse will succeed each other.

The choice of frequency

• If welding with manual filler metal, then F(Hz) synchronized to the gesture,
• If thin plate without TIG electrodes (< 8/10 mm), F(Hz) >> 10Hz

The pulse frequency is set by pressing and releasing the «F(Hz)» button and then actuating the main incremental encoder. Frequency value increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting has been made, it is possible to re- press and release the «F(Hz)» button to re-link the main incremental encoder to the frequency setting or to wait 2 seconds. This frequency ranges from 0.1Hz to 100Hz in Pulse TIG. The incrementation step depends on the frequency range:

• SPOT tacking
  The « SPOT» mode allows the pre-assembly of parts by tacking. The tacking time adjustment allows a better reproducibility and the realization of non-oxidized tack. As default, when the « SPOT « mode is selected, the start and the end of the welding is done at the trigger. However, the « F(Hz) « button and the main encoder allow the user to refine this time. The time in this «SPOT» tacking mode is adjustable from 0 sec. to 60 sec. in steps of 0.1 sec. The ignition is then done with the trigger. To return to an undefined tacking time, simply select «0.0s» as the default value.

• TIG DC – Advanced menu
  It is possible to set the Start and Stop stages of the welding cycle.

• These advanced settings can be accessed by pressing the during 3 seconds until SET and UP are displayed.

• Once the button is released, use the knob to select «SET» from the dropdown menu and confirm by pressing the button.

The knob enables access to these settings :

(access only by TIG DC Pulse)

| 20% – 80% (50% by default)

The setting to modify can be selected by pressing the button. Once the modification is set with the main knob (I), it can be confirmed by pressing the button. The advanced settings menu can be exited with «ESC».

CHOICE OF THE  IGNITION TYPE
TIG HF: non-contact high-frequency ignition
TIG LIFT : Arcing by contact (for environments where HF is not desirable).

1. Place the torch in the welding position above the part (distance of about 2-3 mm between the electrode tip and the part).

2.  Press the torch trigger (the arc starts without contact using High Frequency impulsions).

3.  The initial welding current circulates, the welding carries on according to the welding cycle.

4. Position the torch nozzle and electrode tip on the part and press the torch button.

5.  Tilt the torch until a distance of about 2-3 mm separates the tip of the electrode from the part. The arc starts.

6. Put the position back into position to start the welding cycle.

Warning: Increasing the length of the torch or earth return cables beyond the maximum length specified by the manufacturer will increase the risk of electric shock.

COMPATIBLE TORCHES

TORCHES TRIGGER BEHAVIOUR
For the 1 button torch, the button is called the «main button».
For the 2 buttons torch, the first button is called «main button» and the second button is called «secondary button».

• T1 – The main button is pressed, the welding cycle starts (Pre Gas,  IStart, Up Slope and welding).

• T2 – The main button is released, the welding cycle is stopped (Down Slope, I Stop, Post Gas). For the double button torch and in 2T mode only, the secondary button works like the main button.

• T1 – The main button is pressed, the cycle starts at Pre Gas and stops in the I Start phase.

• T2 – The main button is released, the cycle continues in Up Slope and in welding.

• T3 – The main button is pressed, the cycle switches to Down Slope and stops in I_ Stop.

• T4 – The main button is released, the cycle ends with Post Gas. For the dual-button torch, the secondary button is inactive.

• T1 – The main button is pressed, the cycle starts at Pre Gas and stops in the I_ Start phase.

• T2 – The main button is released, the cycle continues in Up Slope and in welding.
  LOG: this mode is used during welding:

• A brief press of the main button (<0.5s), the current switches from I welding current to I cold and vice versa.

•  the secondary button is kept pressed, the welding current switches from I welding current to I cold

•  the secondary button is kept released, the welding current switched from I cold to I welding current.

• T3 – A long press on the main button (>0.5s), the cycle swicthes to DownSlope and stops in the I_Stop phase.

• T4 – The main button is released, the cycle ends with PostGas.

For the dual button torches the «up» trigger keeps the same function as the single button or trigger torch. The «down» button can, when pressed, switch to the cold current.
