PROTECTING YOURSELF AND OTHERS

Arc welding can be dangerous and cause serious injury or death.

Welding exposes people to a dangerous source of heat, light radiation from the arc, electromagnetic fields (caution to those using pacemakers) and risk of electrocution, as well as noise and fumes.

To protect yourself and others, please observe the following safety instructions:

To protect yourself from burns and radiation, wear insulating, dry and fireproof clothing without lapels. Ensure the clothing is in good condition and that covers the whole body.

Wear protective gloves which provide electrical and thermal insulation.

Use welding protection and/or a welding helmet with a sufficient level of protection (depending on the specific use). Protect your eyes during cleaning procedures. Contact lenses are specifically forbidden.

It may be necessary to section off the welding area with fireproof curtains to protect the area from arc radiation and hot spatter. Inform people in the welding area not to stare at the arc rays or molten parts and to wear appropriate clothing for protection.

Wear noise protection headphones if the welding process becomes louder than the permissible limit (this is also applicable to anyone else in the welding area).

Keep hands, hair and clothing away from moving parts (the ventilation fan, for example).

Never remove the cooling unit housing protections when the welding power source is live, the manufacturer cannot be held responsible in the event of an accident.

Newly welded parts are hot and can cause burns when handled. When maintenance work is carried out on the torch or electrode holder, ensure that it is sufficiently cold by waiting at least 10 minutes before carrying out any work. The cooling unit must be switched on when using a water-cooled torch to ensure that the liquid cannot cause burns.

It is important to secure the working area before leaving it, in order to protect people and property.

WELDING FUMES AND GAS

The fumes, gases and dusts emitted by welding are harmful to health. Sufficient ventilation must be provided and an additional air supply may be required. An air-fed mask could be a solution in situations where there is inadequate ventilation.

Check the extraction system's performance against the relevant safety standards.

Caution: Welding in confined spaces requires safety monitoring from a safe distance. In addition, the welding of certain materials containing lead, cadmium, zinc, mercury or even beryllium can be particularly harmful. Remove any grease from the parts before welding.

Cylinders should be stored in open or well-ventilated areas. They should be stored in an upright position and kept on a stand or trolley.

Welding should not be carried out near grease or paint.

RISK OF FIRES AND EXPLOSIONS

Fully shield the welding area, flammable materials should be kept at least 11 metres away.

Fire fighting equipment should be kept close to wherever the welding activities are being undertaken.

Beware the expulsion of hot spatter or sparks, even through cracks, which can cause fires or explosions.

Keep people, flammable objects and pressurised containers at a safe distance.

Welding in closed containers or tubes is to be avoided. If the containers or tubes are open, they must be emptied of all flammable or explosive materials (oil, fuel, gas residues, etc.).

Grinding work must not be directed towards the source of the welding current or towards any flammable materials.

GAS CYLINDERS

Gas escaping from cylinders can cause suffocation if there is too high a concentration of it in the welding area (ensure good ventilation).

The machine must be transported in complete safety: gas cylinders must be closed and the welding power source turned off. They should be stored upright and supported to limit the risk of falling.

Close the cylinder between uses. Beware of temperature variations and exposure to the sun.

The cylinder must not come into contact with flames, arcs, torches, earth clamps or any other sources of heat or ignition.

Be sure to keep it away from electrical and welding circuits. Never weld a pressurised cylinder.

When opening the cylinder valve, keep your head away from the valve and ensure that the gas being used is suitable for the welding process.

ELECTRICAL SAFETY

The electrical network used must be earthed. Use the recommended fuse size from the rating plate.

An electric shock can be the source of a serious accident, whether directly or indirectly, or even death.

Never touch live parts connected to the live current, either inside or outside the power source casing unit (torches, clamps, cables, electrodes), as these items are connected to the welding circuit.

Before opening the welding machine's power source, disconnect it from the mains and wait two minutes to ensure that all the capacitors have fully discharged.

Do not touch the torch or the electrode holder and the earth clamp at the same time.

If the cables or torches become damaged, they must be replaced by a qualified and authorised person. Measure the cable cross-section according to the intended application. Always use dry and in-fact clothing to insulate yourself from the welding circuit. Alongside this, wear well-insulated footwear in all working environments.

EMC CLASSIFICATION

This Class A device is not intended for use in a residential environment where power is provided by the public low-voltage local supply network. Ensuring electromagnetic compatibility may be difficult at these sites due to conducted, as well as radiated, radio frequency interference.

Provided that the impedance of the public low-voltage supply network is less than Zmax = 0.29 Ohms at the common coupling point, this equipment complies with IEC 61000-3-11 and can be connected to public low-voltage electrical supply. It is the responsibility of the fitter or operator of the equipment to ensure, by consulting the electricity distribution network provider if necessary, that the network impedance complies with impedance restrictions.

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

ELECTROMAGNETIC INTERFERENCES

An electric current passing through any conductor produces localised electric and magnetic fields (EMF). The welding current produces an electromagnetic field around the welding circuit and the welding equipment.

Electromagnetic fields (EMFs) can interfere with some medical devices, for example pacemakers. Protective measures must be taken for people with medical implants. For example, restricted access for onlookers or an individual risk assessment for welders.

All welders should use the following guidelines to minimise exposure to the welding circuit's electromagnetic fields:

• position the welding cables together - securing them with a clamp if possible;
• position yourself (head and body) as far away from the welding circuit as possible,

• never wrap the welding cables around your body,

• do not position yourself between the welding cables. and keep both welding cables on your same side,

• connect the return cable to the workpiece, as close as possible to the area to be welded,
• do not work next to, sit or lean on the source of the welding current,
• do not transport the welding power source or wire feeder while welding.

Pacemaker users should consult a doctor before using this equipment.

Exposure to electromagnetic fields during welding may have other health effects that are not yet known.

RECOMMENDATIONS FOR ASSESSING THE WELDING AREA AND EQUIPMENT

General Information

It is the user's responsibility to install and use the arc welding equipment according to the manufacturer's instructions. If electromagnetic disturbances are detected, it is the user's responsibility to resolve the situation using the manufacturer's technical support. In some cases, this corrective 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 current source and around the entire workpiece by setting up input filters. In any case, electromagnetic interference should be reduced until it is no longer an inconvenience.

Assessing the welding area

Before installing arc welding equipment, the user should assess the potential electromagnetic problems in the surrounding area. The following should be taken into account:

a) the presence of power, control, signal and telephone cables above, below and next to the arc welding equipment,

b) radio and television receivers and transmitters,

c) computers and other control equipment,

d) critical safety equipment, e.g. the protection of industrial equipment,

e) the health of nearby persons, e.g. those using of pacemakers or hearing aids,

f) the equipment used for calibrating or measuring,

g) the protection of other surrounding equipment.

The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This may require further protective measures;

h) the time of day when welding or other operations are to be carried out.

The size of the surrounding area to be taken into account will depend on the building's structure and the other activities taking place there. The surrounding area may extend beyond the boundaries of the premises.

Assessment of the welding equipment

In addition to the assessment of the surrounding area, the arc welding equipment's assessment can be used to identify and resolve cases of interference. It is appropriate that the assessment of any emissions should include in situ procedures as specified in Article 10 of CISPR 11. In situ measurements can also be used to confirm the effectiveness of mitigation measures.

GUIDELINES ON HOW TO REDUCE ELECTROMAGNETIC EMISSIONS

a. The mains power grid: Arc welding equipment should be connected to the mains power grid according to the manufacturer's recommendations. If any interference occurs, it may be necessary to take additional precautionary measures such as filtering the mains power supply. Consider protecting the power cables of permanently installed arc welding equipment within a metal pipe or a similar casing. The power cable should be protected along its entire length. The shield should be connected to the welding power source to ensure that there is good electrical contact between the conduit and the welding power source enclosure.
b. The maintenance of arc welding equipment: Arc welding equipment should be subject to routine maintenance as recommended by the manufacturer. All access points, service openings and bonnets should be closed and properly locked when the arc welding equipment is in use. The arc welding equipment should not be modified in any way, except for those modifications and adjustments mentioned in the manufacturer's instructions. The spark gap of arc starters and stabilisers should be adjusted and maintained according to the manufacturer's recommendations.
c. Welding cables: Cables should be as short as possible, placed close together either near or on the ground.
d. Equipotential bonding: Consideration should be given to linking all metal objects in the surrounding area. However, metal objects connected to the workpiece increase the risk of electric shocks to the user if they touch both these metal parts and the electrode. It is necessary to insulate the operator from such metal objects.
e. Earthing the workpiece: In cases where the part to be welded is unearthed for electrical safety reasons or due to its size and location, such as ship hulls or structural steel buildings, an earthed connection can reduce emissions in some cases, although not always. Care should be taken to avoid the earthing of parts which could increase the risk of injury to users or damage to other electrical equipment. If necessary, the workpiece's connection should be earthed directly, but in some countries where a direct connection is not allowed, the connection should be made with a suitable capacitor chosen according to national regulations.
f. Protection and protective casing: The selective protection and encasing of other cables and equipment in the surrounding area may limit interference problems. The safeguarding of the entire welding area may be considered for special applications.

THE TRANSPORTING AND MOVING OF THE MACHINE'S POWER SOURCE

Do not use the cables or torch to move the welding power source. It should be moved in an upright position. Do not carry or transport the power source overhead of people or objects.

Never lift a gas cylinder and the welding power source at the same time. Their transportation requirements are different.

It is advisable to remove the wire spool before lifting or transporting the welding power source.

SETTING UP THE EQUIPMENT

• Place the welding power source on a floor with a maximum inclination of 10^ .
• Provide sufficient space to ventilate the welding power source and access the controls.
• Do not use in an area with conductive metal dust.
• The welding power source should be protected from heavy rain and not exposed to direct sunlight.
  • The machine is IP23S rated, meaning:
• its dangerous parts are protected from being entered by objects greater than 12.5 mm and,
• it is protected against rain falling at an angle of up to 60° from vertical, providing that any moving parts (fan) are stationary.
  This product can therefore be stored outdoors in accordance with the IP23 protection rating.

Stray welding currents can destroy earthing conductors, damage electrical equipment and devices and cause component parts to overheat leading to fires.

• All welding connections must be firmly secured and regularly checked!
• Make sure that the item's attachment is firm and secure, without any electrical problems!
• Join together or suspend any electrically conductive parts of the welding source such as the frame, trolley and lifting systems so that they are insulated!
• Do not place other equipment such as drills or grinding devices etc. on the welding source, trolley, or lifting systems unless they are insulated!
• Always place welding torches or electrode holders on an insulated surface when not in use!

The power cables, extensions and welding cables must be fully uncoiled to prevent overheating.

The manufacturer assumes no responsibility for damage to persons or objects caused by improper and dangerous use of this equipment.

MAINTENANCE / RECOMMENDATIONS

□ Maintenance should only be carried out by a qualified person. Annual maintenance is recommended.
☐ Switch off the power supply by pulling the plug and wait two minutes before working on the equipment.. Inside the machine, the voltages and currents are high and dangerous.

- Regularly remove the cover and blow out any dust. Take advantage of the opportunity to have the electrical connections checked with an insulated tool by a qualified professional.

Notes:

• Too narrow a sheath can lead to unreeling issues and can lead to the overheating of the motor.
• The torch connection must also be properly tightened to prevent it from overheating.
• Ensure that neither the wire, nor the reel, touches the device's mechanism, otherwise there is a danger of short-circuiting the machine.

RISK OF INJURY FROM MOVING COMPONENTS

The reels have moving parts that can trap hands, hair, clothing or tools causing injuries!

• Do not touch rotating, moving or driving parts of the machine!
• Ensure that the housing covers or protective covers remain fully closed when in operation.
• Do not wear gloves when threading the filler wire or changing the filler-wire's spool.

COOLANT PUMP PRIMING (400T-W)

When using the product for the first time, or after completely emptying the coolant tank, the following procedure must be followed to start the circulation:

• Fill the coolant reservoir to its maximum level. The tank has a 5.5 litre capacity.
• Connect the priming hose (II-ww) to the coolant outlet connector (I-14) and place the other end in an empty container (ideally a bottle).
• Turn on the power source.
• In the «System/Cooling unit» menu, press push-button no. 2 (to start the priming procedure.
• Once the pump is primed (container is filling with coolant), stop the cooling unit by pressing one of the buttons on the HMI.
• Disconnect the priming hose and return the liquid to the cooling system: the pump is now primed.

LIQUID COOLING (400T-W)

FILLING

The cooling unit tank must be filled to the MAX level indicated by the gauge on the front, and must never be allowed to fall below the MIN level. A warning message will be triggered if this occurs.

It is essential to use a specific coolant for welding machines that has low electrical conductivity as well as being anti-corrosion and anti-freeze (ref. 052246).

The use of other coolants, in particular the standard automotive coolants, can lead to the accumulation of solid deposits in the cooling system through electrolysis, thus degrading the cooling system and even clogging it entirely.

This recommended MAX level is essential for optimum performance of the liquid-cooled torch.

Any damage to the machine caused by the use of a coolant other than the recommended variety will not be covered under the warranty..

USAGE

1 NEVER USE the machine's power source WITHOUT COOLING LIQUID while the pump is running.
Meet the minimum coolant level. Failure to do so may result in permanent damage to the cooling system pump.
2. Ensure that the cooling unit is switched off before disconnecting the torch's fluid inlet and/or outlet pipes. Coolant is harmful and irritates the eyes, mucous membranes and skin. Hot liquid can cause burns.
3. Danger of burns from hot liquid. Never drain the cooling unit after use. The liquid inside the machine is boiling hot, wait for it to cool before draining.
In «AUTO» mode, the cooler pump starts running when welding is started. When welding stops, the pump continues to run for a further 10 minutes. During this time, the liquid cools the welding torch bringing it back to room temperature. Leave the power source plugged in for a few minutes after welding to allow it to cool.

In the MIG-MAG process, the cooling system is activated by default (AUTO). To use an air-cooled MIG-MAG torch, it is necessary to switch the cooling system off. Please refer to the interface manual to do this.

SEMI-AUTOMATIC STEEL/STAINLESS STEEL WELDING (MAG MODE)

This machine can weld steel and stainless steel wire from 0.6 to 1.2mm (I-A). The unit is supplied with 1.0/1.2 rollers for steel or stainless steel as standard. The contact tip, the grooved roller, and the torch sheath are designed for this application.

For operation on steel, a specific welding gas (Ar+CO2) is required. The amount of CO2 may vary depending on the type of gas used. For stainless steel, use a 2% CO2 mixture. When welding with pure CO2, it is necessary to connect a gas pre-heater to the gas cylinder. For specific gas issues, please contact your gas distributor. The gas flow rate for steel is between 8 and 15 litres per minute depending on the surroundings. To check the gas flow rate on the manometer without unwinding the welding wire, press and hold push-button n°1 and follow the procedure on the screen. This check should be done periodically to ensure the best possible welding. Refer to the HMI manual.

SEMI-AUTOMATIC ALUMINIUM WELDING (MIG MODE)

The unit can weld aluminium wire from ∅ 0.8 to 1.2mm (I-B).

For use with aluminium, pure argon gas (Ar) is required. Seek advice from a gas distributor for a wide selection of gases. The gas flow rate for aluminium is between 15 and 20 l/min depending on the surrounding environment and the welder's experience.

The differences between steel and aluminium processing are as follows:

• Use specific rollers for aluminium welding.
• Put minimum pressure on the motorised reel's pressure rollers so as not to crush the thread.
• Only use the capillary tube (for guiding the wire between the feed rollers and the EURO connector) for steel/stainless steel welding (I-B)
• Use a special aluminium torch. This aluminium torch has a Teflon coating to reduce friction. DO NOT cut away the coating at the tip of the connector! This coating is used to guide the wire from the rollers.
• Contact tips: use a SPECIAL aluminium contact tip that matches the wire's diameter.

When using red or blue sheathing (for aluminium welding), it is recommended to use the accessory 90950 (I-C). This stainless steel sheath guide improves the centering of the sheath and facilitates the flow of the wire.

SEMI-AUTOMATIC WELDING IN CUSI AND CUAL (BRAZING MODE)

The unit can weld ∅ 0.8 and 1.0 mm CuSi and CuAl wire.

In the same way as with steel, a capillary tube must be set up and a torch with a steel sheath must be used. For brazing, pure argon (Ar) should be used.

SEMI-AUTOMATIC WELDING WITH CORED WIRE

The unit can weld flux-cored wire from ∅ 0.9 to 1.6mm. The original rollers must be replaced by specific cored wire rollers (available as an optional extra). Welding flux-cored wire with a standard nozzle can lead to overheating and damage to the torch. Remove the original nozzle from your MIG-MAG torch.

CHOOSING A POLARITY

Polarity + Polarity -

Line drawing of a portable electronic device with control panel and wiring (no text or symbols)

Gas-shielded MIG/MAG welding generally requires positive polarity.

Line drawing of a mobile phone chassis with wheels and control panel (no text or symbols)

MIG/MAG welding without gas shielding (No Gas) generally requires negative polarity.

In any case, refer to the wire manufacturer's recommendations for the choice of polarity for your MIG-MAG torch.

GAS SUPPLY

• Fit a suitable pressure regulator to the gas cylinder. Connect it to the welding station with the pipe supplied. Attach the two hose clamps to prevent leaks.
• Ensure that the gas cylinder is held securely in place with a chain attached to the power source.
• Set the gas flow rate by adjusting the dial on the pressure regulator.
  NB: To adjust the gas flow rate more easily, use the rollers on the motorised spool by pulling the trigger on the torch (loosen the brake wheel on the motorised reel so that no wire is drawn in). Maximum gas pressure: 0.5 MPa (5 bar).

This procedure does not apply to welding in «No Gas» mode.

SPOT WELDING MODE

- Spot

This welding mode allows the pre-assembly of parts before welding. Spot welding can be done manually using the trigger or timed with a predefined spot welding period. Spot welding allows for better reproduction and non-oxidised weld points.

- Spot-Delay

This is a welding mode similar to Spot welding but with predefined weld and dwell times, as long as the trigger is held down. This function allows welding very thin steel or aluminium metal sheet, limiting the risk of piercing and distortion (especially for aluminium welding).

CONFIGURING THE SETTINGS

	Units
Burnback -		Feature to help prevent the wire sticking to the bead. This is timed to coincide with the wire rising from the weld pool.
Crater Filler %/s		This idling current is the next phase after the current is lowered.The intensity (% of welding current) and the time (seconds) can be programmed.
Delay s Time between the end of a point (excluding Post-Gas) and the start of a new point (including Pre-Gas).
Thickness mm		The pre-installed user settings (synergies) allow for a fully-automatic set-up. Changing the thickness setting automatically sets the appropriate wire tension and speed.
Crater-fill feature s Downslope current.
Hot Start %/s		The Hot Start is an overcurrent used at the start that prevents the wire from sticking to the workpiece. The intensity (% of welding current) and the time (seconds) can be programmed.
Current A The welding current is adjusted according to the type of wire used and the material to be welded.
I Start - Adjustment of the ignition current.
Arc length - Used to adjust the distance between the end of the wire and the weld pool (tension adjustment).
Pre-Gas s When the torch is bled and the gas shield is created before ignition.
Tack welding	s Set duration.
Post-Gas s		Duration of the gas protection after the arc is extinguished. It protects the workpiece and the electrode from oxidation.
Self-Induction Coil	-	Lessens the welding current more or less. To be set according to the welding position.
Spot welding	s Set duration.
Voltage	V Control over the cord's width.
Upslope	s Upslope current
Approach speed	-	Progressive yarn speed. Before priming, the wire moves slowly to create the first contact without jolting.
Wire speed	m/min	Amount of filler metal deposited and consequently the welding intensity and penetration.

Access to some of the welding settings depends on the selected welding process (Manual, Standard, etc.) and the selected display mode (Easy, Expert or Advanced). Refer to the HMI manual.

GAS FLOW CONTROL

To check the gas flow rate on the manometer without unwinding the welding wire, press and hold push-button n°1 and follow the procedure on the screen. This check should be done periodically to ensure the best possible welding. Refer to the HMI manual.

TIG (GTAW) WELDING MODE

INSTALLATION AND GUIDANCE

• DC TIG welding requires a protective gas shield (Argon).
• Connect the earth clamp to the positive (+) plug connector. Connect the optional TIG torch (ref. 046108) into the EURO connector of the power source and the polarity reversal cable into the negative (-) socket.
• Ensure that the torch is properly fitted and that the consumables (vice grip pliers, collet bodies, diffusers and nozzles) are not worn out.
• The choice of electrode will depend on the current of the DC TIG process.

ELECTRODE SHARPENING

For optimum results, it is advised to use an electrode sharpened in the following way:

d L

L = 3 x d for a low current. L = d for a high current

SETTINGS

- Standard

The standard DC TIG welding process allows high quality welding on most ferrous materials such as steel and stainless steel, but also copper and its alloys including titanium. The various current and gas management possibilities allow you to perfectly control your welding operation, from priming to the final cooling of your weld seam.

- Pulse

This pulsed current welding mode combines high current pulses (I = welding pulses) with low current pulses (cold I, workpiece cooling pulses). The pulsed mode allows parts to be assembled while limiting temperature rises and warping. Ideal for on site use.

Example:

The welding current (I) is set to 100 A and % (cold I) = 50%, i.e. cold current = 50% x 100 A = 50. F(Hz) is set to 10 Hz, the signal period will be 1/10 Hz = 100 ms -> a 100 A pulse every 100 ms then followed by another at 50 A.

- Spot

This welding mode allows the pre-assembly of parts before welding. Spot welding can be done manually using the trigger or timed with a predefined spot welding period. Spot welding allows for better reproduction and non-oxidised weld points.

- Spot-Pulse

This method of welding is used to pre-assemble thin sheet metal workpieces prior to the actual welding process. Spot welding can be done manually using the trigger or timed with a predefined spot welding period. Spot welding allows for better reproduction and non-oxidised weld points.

MANUAL GAS PURGE

The presence of oxygen in the torch can lead to a decrease in mechanical quality and can result in less corrosion resistance. To flush the gas from the torch, press and hold button no. 1 and follow the on-screen procedure. Refer to the HMI manual.

MMA (SMAW) WELDING MODE

INSTALLATION AND GUIDANCE

• Plug the cables, electrode holder and earth clamp into the plug connections.
• Respect the electrical polarities and the strength of the welding power indicated on the electrode boxes.
• Remove the coated electrode from the electrode holder when the welding power source is not in use.
  • The equipment is fitted with 3 inverter-specific features:
• Hot Start provides an overcurrent at the beginning of the welding process.
• Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
• The Anti-Stick technology makes it easier to unstick the electrode from the metal.

PROCESS SETTINGS

		Welding processes
Settings Settings Standard Pulsed
Electrode type	RutileBasic	√	√	The type of electrode determines the settings in order to optimise its weldability depending on the type of electrode used.
Anti-Sticking ON-OFF		√	√	The anti-stick feature is recommended to safely remove the electrode in the event of it sticking to the workpiece (the current is cut off automatically).

Access to some of the welding parameters depends on the selected display mode: Settings/Display mode: Easy or Expert. Refer to the HMI manual.

WELDING PROCESSES

- Standard

This standard MMA welding mode is suitable for most welding applications. It enables welding with all types of coated, rutile, basic and cellulosic electrodes, as well as on all materials: steel, stainless steel and cast iron.

- Pulse

The pulsed MMA welding mode is suitable for upright (PF) applications. The pulsed setting keeps the weld pool cold while promoting material transfer. Without pulsing, vertical upward welding requires a 'Christmas tree' movement, i.e. a difficult triangular movement. Thanks to Pulsed MMA welding, it is no longer necessary to perform this movement. Depending on the thickness of your workpiece, a straight upward movement should suffice. However, if you want to enlarge your weld pool, a simple sideways movement similar to downheld welding is sufficient.. In this case, you can set the frequency of your pulsed current on the display screen. This method offers greater control of the vertical welding operation.

CHOOSING COATED ELECTRODES

• Rutile electrodes: very easy to use in any position.
• Basic electrodes: it can be used in all positions and is suitable for safety work due to its increased mechanical properties.

5	150-290	200-260
6.3	200-385	220-340

ADJUSTING THE ARC FORCE

It is advisable to set the Arc Force to the middle position (0) to start welding and then adjust it according to the results obtained and individual welding preferences. Note: The adjustment range of the Arc Force is specific to the type of electrode chosen.

Traceability\*

*This feature is not activated as default. It can be activated via the online configurator, available on Planet GYS / Tools / Product configuration. To activate it, contact your distributor.

This welding management interface is designed to trace/record all the steps of the welding operation, bead by bead, during manufacturing. This qualitative approach ensures a post-production welding quality that allows the analysis, evaluation, reporting and documentation of the recorded welding parameters. This feature allows for the accurate and fast collection and storage of data required under EN ISO 3834. This data can be recovered and exported with a USB stick.

1- Start - Creation of traceability

• Customise the name of the job by pressing the thumbwheel.
• Sampling interval:
• Hold: No recording of current/voltage values (average along the wire) during welding.
• 250 ms, 500 ms, etc. : recording of current/voltage values (average along the wire) every «X» milliseconds or seconds during welding.

Press «REC» to start traceability

Traceability display

At the top left of the main screen, a red symbol is displayed to indicate that a record is being made for traceability.

Calibration

Calib. Cables

Function dedicated to the calibration of welding accessories such as MIG torch, or electrode holder and ground clamp cables. The purpose of calibration is to compensate for variations in the length of the accessories in order to match the selected voltage value. Once started, the procedure is illustrated with an animation on the screen.

Important: The cable calibration must be repeated each time the torch, harness or ground cable is changed to ensure optimal welding performance.

Gas flow control (MIG-MAG)

In the main screen, holding down on button no. 1 allows you to adjust the gas flow on the manometer without unwinding the supply wire. Once started, the procedure is illustrated with an animation on the screen. The gas flow setting should be checked periodically to ensure optimal welding.

Gas purge (TIG)

The presence of oxygen in the torch can lead to a decrease in mechanical quality and can result in less corrosion resistance. To flush the gas from the torch, press and hold button no. 1 and follow the on-screen procedure.

Wire loading (MIG-MAG)

To unwind the wire in the MIG/MAG torch without using gas, please follow the procedure below:

1- Hold the trigger down in a non-welding position.

2- When the process is shown on the display, you can release the trigger.

3- The wire starts to feed. 3m of wire feeds at a speed of 5m/min by default. You can change these values with the thumbwheel.

If you wish to exit the animation without waiting for the wire to finish feeding, press the trigger briefly.
