INDIVIDUAL PROTECTION & OTHERS

Arc welding can be dangerous and can cause serious injury or even death. Welding exposes the user to dangerous heat, arc rays, electromagnetic elds, risk of electric shock, noise and gas fumes. People wearing pacemakers are advised to consult a doctor before using the welding machine. To protect oneself as well as others, ensure the following safety precautions are taken: In order to protect you from burns and radiations, wear clothing without turn-up or cu󰀨s. These clothes must be insulating, dry, reproof, in good condition and cover the whole body. Wear protective gloves which guarantee electrical and thermal insulation. Use su󰀩cient welding protective gear for the whole body: hood, gloves, jacket, trousers... (varies depending on the application/ operation). Protect the eyes during cleaning operations. Contact lenses are prohibited during use. It may be necessary to install reproof welding curtains to protect the area against arc rays, weld spatter and sparks. Inform the people around the working area to never look at the arc nor the molten metal, and to wear protective clothes. 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). Keep hands, hair and clothes away from moving parts such as fans, and engines. Never remove the safety covers from the cooling unit when the machine is plugged in. The manufacturer is not liable for any injury or damage due to non-compliance with the safety precautions. Parts that have just been welded will be hot and may cause burns when touched. During maintenance work on the torch or the electrode holder, you should make sure that temperature is cold enough and wait at least 10 minutes before any intervention. When using a water-cooled torch, make sure that the cooling unit is switched on to avoid any burns that could potentially be caused by the liquid. It is important to secure the working area before leaving it to ensure protection of the goods and the safety of people.

WELDING FUMES AND GAS

Fumes, gas and dust produced during welding are hazardous to health. It is mandatory to ensure adequate ventilation and/ or extraction to keep fumes and gas away from the work area. Using an air fed welding helmet is recommended in case of insu󰀩cient ventilation in the workplace. Check that the air supply is suitable by referring to the recommended safety regulations. Precautions must be taken when welding in small areas, and the operator will need supervision from a safe distance. Welding specic pieces of metal containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user will also need to remove the grease from the workpiece before welding.22 User manual

Translation of the original instructions Gas cylinders must be stored in an open or ventilated area. They must be stored vertically and held by a support or trolley to limit the risk of fall. Do not weld in areas where grease or paint are stored.

FIRE AND EXPLOSION RISKS

Protect the entire welding area. Flammable materials must be moved to a minimum safe distance of 11 meters. A re extinguisher must be readily available near the welding operations. Be careful of spatter and sparks, even through cracks. If not careful then this could potentially lead to a re or an explosion. Keep people, ammable materials/objects and containers that are under pressure at a safe distance. Welding in closed containers or pipes should be avoided and , if they are opened, they must be emptied of any ammable or explosive material (oil, fuel, gas ...). Grinding operations should not be carried out close to the power supply or any ammable materials. GAS CYLINERS Gas leaking from the cylinders can lead to su󰀨ocation if present in high concentration around the work area (ventilation required). Transport must be done safely: cylinders closed and the welding current source switched o󰀨. They must be stored vertically and held by a support to limit the risk of falling. Close the cylinder between two uses. Beware of temperature variations and sun exposure. The cylinder must not be in contact with a ame, electric arc, torch, earth clamp or all other sources of heat. Always keep gas cylinders away from electrical circuits, and therefore never weld a cylinder under pressure. Be careful when opening the valve on the gas bottle, it is necessary to remove the tip of the valve and to ensure that the gas meets your welding requirements. ELECTRICAL SAFETY The electrical mains used must have an earth terminal. Use the recommended fuse size. An electric shock could cause serious injuries or potentially even 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 the earth clamp at the same time. Damaged cables and torches must be changed by a qualied technician. Make sure that the cable cross section is adequate with the usage (extensions and welding cables). Always wear dry clothes which are in good condition in order to be isolated from the welding circuit. Wear insulating shoes, regardless of the workplace/environment in which you work in. EMC CLASSIFICATION This Class A machine is not intended to be used on a residential site where the electric current is supplied by the domestic low- voltage power grid. There may be potential di󰀩culties in ensuring electromagnetic compatibility at these sites, due to conducted interferences as well as radiation. Provided that the impedance of the low-voltage public electrical network at the common coupling point is less than Zmax = 0.282 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 netwtork operator if necessary, that the network impedance complies with the impedance restrictions. This equipment complies with the IEC 61000-3-12 standard. ELECTROMAGNETIC INTERFERENCES The electric current owing through any conductor causes electrical and magnetic elds (EMF). The welding current generates an EMF around the welding circuit and the welding equipment. The EMF electromagnetic elds can interfere with certain medical implants, such as pacemakers. Protective measures must be taken for people having medical implants. For example, by restricting access to passers-by or conducting an individual risk evaluation for the welders. All welders should use the following procedures to minimise exposure to electromagnetic elds from the welding circuit:

• position the welding cables together - secure them with a clamp, if possible;

• position your torso and head as far as possible from the welding circuit

• never wrap the cables around the body.

• do not position the body between the welding cables. Hold both welding cables on the same side of the body;EN

Translation of the original instructions

• connect the earth clamp as close as possible to the area being cut;

• do not work next to the welding power source, do not sit or lean on it.

• do not weld when transporting the welding current source or the wire feeder. People wearing pacemakers are advised to consult their doctor before using this device. Exposure to electromagnetic elds while welding may have other health e󰀨ects which are not yet identied. RECOMMENDATIONS FOR EVALUATING THE WELDING AREA AND INSTALLATION General points The user is responsible for the installation and use of the arc welding equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected, the user is responsible for resolving the situation with the manufacturer’s technical assistance. In some cases, this corrective action may be as simple as earthing the welding circuit. In other cases, it may be necessary to build an electromagnetic shield around the welding power source and around the entire piece by tting input lters. In all cases, electromagnetic interferences must be reduced until they are no longer an issue. 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. The following should be taken into account: a) the presence (above, below and next to the arc welding machine) of other power cables, remote cables and telephone cables; b) Radio/TV transmitters and receptors; c) computers and other control equipment; d) safety-critical equipment, e.g. protection of industrial equipment; e) the health of neighbouring persons, e.g. use of pacemakers or hearing aids; f) the equipment used for calibration or measurement; g) the immunity of other materials in the environment. The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This may require additional protective measures; h) the time of day during the welding or other activities have to be performed. The dimension of the cutting area that has to be considered depends on the size and shape of the building and the type of work undertaken. The area taken into consideration might go beyond the limits of the installations. Welding area assessment Besides the welding area assessment, 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 specied in Article 10 of CISPR 11. In situ measurements can also be used to conrm the e󰀨ectiveness 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 in accordance with the manufacturer’s recommendation. In case of interferences, it may be necessary to take additional precautions such as the ltering of the power supply network. Consideration should be given to shielding the power supply cable in a metal conduit or equivalent of permanently installed arc welding equipment. It is necessary to ensure the electrical continuity of the frame along its entire length. The shielding should be connected to the welding current source to ensure a good electrical contact between the conduit and the casing of the welding current source. b. Maintenance of arc welding equipment: The arc welding machine should be subject to a routine maintenance check according to the recommendations of the manufacturer. 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 modied in any way, except for the changes and settings outlined in the manufacturer’s instructions. The spark gap of the arc starts and arc stabilization devices must be adjusted and maintained according to manufacturer’s recommendations.c. c. Welding cables: Welding cables: Cables must be as short as possible, close to each other and close to the ground, if not on the ground. d. Equipotential bonding: Consideration should be given to bond 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. f. Protection and shielding: The selective protection and shielding of other cables and devices in the area can reduce perturbation issues. The protection of the entire welding area can be considered for specic situations. TRANSPORT AND TRANSIT OF THE WELDING MACHINE The machine is equipped with a handle to easy transportation. Be careful not to underestimate the weight of the machine. The handle cannot be used to hang or attach the machine on something else. 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. The transport rules applying to each item are di󰀨erent. Do not place/carry the unit over people or objects.24 User manual

CONNECTION TO A GENERATOR

This equipment may operate with generators provided that the auxiliary power meets the following requirements: - The voltage must be alternating, adjusted as specied and with a peak voltage of less than 400 V, - The frequency must be between 50 and 60 Hz. It is imperative to check these requirements as many generators generate high voltage peaks that can damage the machine.

USE OF EXTENSION LEADS

All extension cables must have an adequate size and section, relative to the machine’s voltage. Use an extension lead that complies with national safety regulations. Voltage input Length and thickness of the extension lead <45 m <100 m 230 V 2.5 mm² 2.5 mm² GAS CONNECTION This equipment is equipped with two connections. A cylinder connector for the gas inlet into the station, and a torch gas connector for the gas outlet at the end of the torch. We recommend that you use the adaptors supplied with your set to ensure an optimal connection. LIQUID COOLING

MAX MIN The tank of the cooling unit must be lled to the recommended MAX level of the gauge on the back of the cooling unit, but never below the MIN level, unless a warning message is displayed. Use a coolant with low electrical conductivity, anti-corrosion and anti-freeze specic to welding machines (recommended coolant ref 052246). To obtain the best cooling performance from this unit, distilled or demineralised water should be used. Please note that water can only be used in ambient temperatures above 5°C. The use of other coolants, and in particular standard automotive coolant, can lead to the accumulation of solid deposits in the cooling circuit through electrolysis, thus degrading the cooling, and even blocking the circuit. This recommended MAX level is essential to optimise the operating factors of the associated water-cooled torch. Any damage to the machine caused by the use of a coolant other than the recommended type or distilled or demineralised water will not be considered under the warranty.

1.) NEVER USE the cooling unit WITHOUT COOLANT when the pump is running. Respect the minimum coolant level. Failure to do so may result in permanent damage to the cooling system’s pump. 2.) Ensure that the cooling unit is switched o󰀨 before disconnecting the liquid-cooled torch’s inlet and/or outlet pipes. Coolant is hazardous and irritates eyes, mucous membranes and skin. The hot liquid can cause burns. 3.) Hot liquid burn hazard. Never drain the cooling unit after use. The liquid inside will be boiling, wait for it to cool down before draining. The cooling unit must be switched o󰀨 (OFF) to use an air-cooled TIG torch. For further instructions on how to do this, see page 33. ACTIVATION OF THE VRD FUNCTION (VOLTAGE REDUCTION DEVICE) This device protects the welder. The welding current is delivered only when the electrode is in contact with the part (low resistance). As soon as the electrode is removed, the VRD function lowers the voltage to a very low value. The VRD function is disabled as standard. However, this can be activated by means of an ON/OFF switch on the power source control board. To access it, follow the steps below:

1. DISCONNECT THE PRODUCT FROM THE POWER SUPPLY BEFORE HANDLING.

2. Remove the screws to take the power source cover o󰀨.

3. Locate the switch on the main board (circled in the diagram below).

4. Turn the switch located on this control card ON.

5. The VRD function is activated.

6. Screw the power source cover back on.

7. On the interface (HMI), the VRD function LED is lit.

To deactivate the VRD function, simply turn the switch located on the control board back to OFF. The VRD LED on the HMI is turned o󰀨.26 User manual

CONNECTIONS AND RECOMMENDATIONS

• Connect the electrode holder and earth clamp to the corresponding sockets.

• Ensure that the welding polarities and intensities indicated on the electrode packaging are observed.

• Remove the electrode from the electrode holder when the machine is not in use.

CHOICE OF COATED ELECTRODES

• Rutile electrode: very easy to use in all positions with DC current

• Basic electrode: used in all CC positions, it is suitable for safety work due to its increased mechanical properties. MMA STANDARD This standard MMA welding mode is suitable for most applications. It allows welding with all types of coated electrodes, rutile, basic and on all mate- rials: steel, stainless steel and cast iron. MMA Standard The grey areas are not useful for this mode. Designation Setting Description & advice Percentage of Hot Start 0 - 100 % The Hot Start is an overcurrent during priming to prevent the wire from sticking to the part to be welded. It is set in Intensity and Time. Welding current 10 - 200 A The welding current is adjusted according to the type of electrode chosen (refer to the electrode packaging). Arc Force -10 / +10 The Arc Force is an overcurrent delivered when the electrode or drop comes into contact with the solder bath in order to avoid sticking.EN

Translation of the original instructions Pulse MMA 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 di󰀩cult «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 is set, it is possible to press and release again the «F(Hz)» button to re-link the main incremental encoder to the current setting or to wait 2 seconds.

• StandardThe TIG DC Standard welding process allows high quality welding on most ferrous materials such as steel, stainless steel, but also copper and its alloys, titanium. The many possibilities of current and gas management allow you to perfectly control your welding operation, from priming to nal cooling of your welding rod. TIG DC Standard The grey areas are not useful for this mode. 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 keeping the machine cool. Example : The welding current I is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A. F(Hz) is set to 2 Hz, the signal period will be 1/2Hz = 500 ms. Every 250ms, a 100A pulse then a 50A pulse will succeed each other. Pulse TIG DC The grey areas are not useful for this mode. Recommendations: Choice of frequency:

• If welding with manual ller metal, then F(Hz) synchronised to the ller metal action,

• If thin without ller (< 0.8 mm), F(Hz) >> 10Hz 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.

SAVE AND LOAD WELDING SETTINGS

The current settings are automatically saved and loaded at start up. In addition to the current settings, it is possible to save and recall so-called «JOB» congurations. The « JOB « button is used to save, recall or delete a conguration. 50 Jobs can be stored per welding process. Job creation - Adjust all desired welding parameters, - Press and hold the «JOB» button for more than 3 seconds, - « IN » appears on the display, - Select a job number using the incremental encoder. Only numbers that are not already associated with a previously saved job can be selected and are indicated on the display, - Once the job number is chosen, press the «JOB» button to validate and save it under the selected number, - The job number is then displayed, indicating that the job has been saved. The number display continues to ash until another button or the torch trigger is activated. Note: If all numbers are already assigned to saved jobs, the HMI displays «Full». Job recall Apart from not being in the process of welding, the job recall does not require any particular initial condition: - Press the «JOB» button briey (not exceeding 2 seconds), - « OUT » appears on the HMI display, - With the incremental encoder, select a job number. Only the numbers associated with existing jobs appear on the display If no job is stored, the HMI displays «- - - -». - Once the job number is selected, press the «JOB» button to conrm the conguration. The job number then ickers on the display, indicating that the job was loaded. The number continues to icker until another parameter is changed or until the torch trigger is pressed to start the welding cycle. Job deletion - Press the «JOB» button briey (not exceeding 2 seconds), - « OUT » appears on the HMI display, - With the incremental encoder, select a job number. Only numbers associated with existing jobs can be displayed, - Press the « JOB » button 3 consecutive times. The selected job is now deleted and the power source displays the welding current again.34 User manual

Secondary button >0.5s<0.5s<0.5sT1 - The main button is pressed, the cycle starts from the PreGas and stops in the I_Start phase.T2 - The main button is released, the cycle continues in UpSlope and in welding.LOG: this operating mode is used in the welding phase:- A short press of the main button (<0.5s) switches the current from I welding to I cold and vice versa.- the secondary button is kept pressed, the current switches from I welding to I cold.the secondary button is released, the current switches from I cold to I welding.T3 – A long press on the main button (>0.5s), the cycle switches to DownSlope and stops in the I_Stop phase.T4 - The main button is released, the cycle ends with PostGas. For this mode it may be convenient to use the dual button torch option or dual button with potentiometer. 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. The potentiometer of the torch, where avai- lable, can control of the welding current from 50% to 100% of the value displayed.
