Familiarise yourself with the device, its proper use and the safety instructions using these operating instructions. The rating plate contains all technical data of this welder; please learn about the technical features of this device. Repairs and/or maintenance work must only be carried out by qualied electricians. Only use the welding cables provided in the scope of delivery. During operation, the device should not be positioned directly against the wall, covered or jammed between other devices so that sucient air can always be absorbed through the ventila- tion slats. Make sure that the device is correctly connected to the mains voltage. Avoid any form of tensile stress of the power cable. Disconnect the mains plug from the socket prior to setting up the device in another location. If the device is not in operation, always switch it o by pressing the ON/OFF switch. Place the electrode holder on an insulated surface and only remove the electrodes from the holder after allowing it to cool down for 15 minutes. Pay attention to the condition of the welding cable, torch and the earth clamps. Wear and tear of the insulation and the live parts can lead to hazards and reduce the quality of the welding work. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 9472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 9 18.10.2024 10:05:1418.10.2024 10:05:1410 GB/IE/NI/CY/MT Arc welding creates sparks, molten metal parts and smoke. Therefore ensure that: All ammable substances and/or materials are removed from the work station and its immediate surrounding. Ensure the workplace is ventilated. Do not weld on containers, vessels or tubes that contain or con- tained ammable liquids or gases. WARNING! Avoid any form of direct contact with the welding current circuit. The no-load voltage between the electrode holder and earth clamp can be dangerous, there is a risk of electric shock. Do not store the device in a damp or wet environment or in the rain. Protection rating IP21S is applicable in this case. Protect your eyes using the appropriate protective glasses (DIN level 9–10), which are fastened to the supplied welding mask. Wear gloves and dry protective clothing that are free of oil and grease to protect the skin from exposure to ultraviolet radiation of the arc. WARNING! Do not use the welding power source to defrost pipes. Please note: The light radiation emitted by the arc can damage eyes and cause burns to the skin. Arc welding creates sparks and drops of melted metal. The welded workpiece starts to glow and remains hot for a relatively long period of time. Therefore, do not touch the workpiece with bare hands. Arc welding can cause vapours to be released that may be hazardous to health. Be careful not to inhale these vapours. Protect yourself from the harmful eects of the arc and keep people that are not involved in the work away from the arc, maintaining a distance of at least 2 m. ATTENTION! During the operation of the welder, other consumers may expe- rience problems with the voltage supply depending on the net- 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 10472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 10 18.10.2024 10:05:1418.10.2024 10:05:1411GB/IE/NI/CY/MT work conditions at the connection point. In case of doubt, please contact your energy supply company. During the operation of the welder, other devices may malfunc- tion, e.g. hearing aids, cardiac pacemakers, etc. z Potential hazards during arc welding There are a series of potential hazards that can occur during arc welding. It is therefore particularly important for the welder to observe the following rules to avoid endangering him/herself and others and to prevent damage to people and the device. Work on the voltage side, e.g. on cables, plugs, sockets etc., may only be carried out by qualied electricians according to national and local regulations. In the event of accidents, disconnect the welder from the mains voltage immediately. If electrical contact voltages occur, switch o the device immedi- ately and have it checked by a qualied electrician. Always ensure good electrical contacts on the welding current side. Always wear insulating gloves on both hands during welding work. These provide protection from electrical shocks (no-load voltage of the welding current circuit), harmful radiations (heat and UV radiation) and incandescent metal and splashes of slag. Wear sturdy, insulating shoes. The shoes should also insulate when exposed to moisture. Loafers are not suitable as falling incandescent metal droplets can cause burns. Wear suitable protective clothing, no synthetic garments. Do not look into the arc without eye protection; only use a weld- ing mask with the prescribed protective glass as per DIN. In addition to light and heat radiation, which can dazzle or cause burns, the arc also emits UV radiation. Without suitable pro- tection the invisible ultraviolet radiation can cause very pain- ful conjunctivitis which is not apparent until several hours later. Furthermore, UV radiation can cause sunburn-like eects on unprotected parts of the body. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 11472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 11 18.10.2024 10:05:1418.10.2024 10:05:1412 GB/IE/NI/CY/MT Any persons in the vicinity of the arc or helpers must also be informed of the dangers and be equipped with the necessary protective equipment. If necessary, set up protective walls. Ensure an adequate supply of fresh air whilst welding, particularly in small spaces, as welding produces smoke and harmful gases. No welding work may be carried out on containers that have been used for storing gases, fuels, mineral oils or similar – even if they have been empty for a long time – as possible residues may present a risk of explosion. Special regulations apply in rooms where there is a risk of re or explosion. Welded joints that are subject to heavy stress loads and are required to comply with certain safety requirements may only be carried out by specially trained and certied welders. Examples of this are pressure vessels, running rails, tow bars, etc. ATTENTION! Always connect the earth clamp as close as possible to the point of weld to provide the shortest possible path for the welding current from the electrode to the earth terminal. Never connect the earth clamp to the housing of the welder! Never connect the earth clamp to earthed parts far away from the work- piece, e.g. a water pipe in another corner of the room. This could otherwise damage the protective bonding system of the room you are welding. Do not use the welder in a moist environment. Only place the welder on a level surface. Do not use the welder in the rain. The outlet is measured at an ambient temperature of 20 °C and welding time can be reduced in the event of higher temperatures. Risk of electric shock: Electric shock from a welding electrode can be fatal. Do not weld in rain or snow. Wear dry insulating gloves. Do not touch the electrodes with bare hands. Do not wear wet or damaged gloves. Protect yourself from electric shock with insula- tion against the workpiece. Do not open the device housing. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 12472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 12 18.10.2024 10:05:1418.10.2024 10:05:1413GB/IE/NI/CY/MT Danger from welding fumes: Inhalation of welding fumes can endanger health. Do not keep your head in the fumes. Use the equipment in open areas. Useextractors to remove the fumes. Danger from welding sparks: Welding sparks can cause an explosion or re. Keep ammable substances away from the welding location. Do not weld near ammable materials. Welding sparks can cause res. Keep a re extinguisher close by and an observer should be present to be able to use it immediately. Do not weld on drums or any other closed containers. Danger from arc beams: Arc beams can damage your eyes and injure your skin. Wear a hat and safety goggles. Wear hearing protection and high, closed shirt collars. Wear welding safety helmet and make sure you use the appropriate lter setting. Wear complete body protection. Danger from electromagnetic elds: Welding current generates electromagnetic elds. Do not use if you have a medical implant. Never wrap the welding cable around your body. Guide welding cables together. z Welding mask-specic safety instructions With the help of a bright light source (e.g. lighter) examine the proper functioning of the welding shield prior to starting with any welding work. Weld spatters can damage the protective screen. Immediately replace damaged or scratched protective screens. Immediately replace damaged or highly contaminated or splat- tered components. The device must only be operated by people aged 16 or over. Please familiarise yourself with the welding safety instructions. Also refer to the safety instructions of your welder. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 13472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 13 18.10.2024 10:05:1418.10.2024 10:05:1414 GB/IE/NI/CY/MT Always wear a welding mask while welding. If you do not do this, you could sustain severe lesions to the retina. Always wear protective clothing during welding operations. Never use the welding shield without the protective screen because this could damage the optical unit. There is a risk of damage to the eyes! Regularly replace the protective screen to ensure good visibility and fatigue-proof work. z Environment with increased electrical hazard When welding in environments with increased electrical hazard, the following safety instructions must be observed. Environments with increased electrical hazard may be encountered, for example: In workplaces where the space for movement is restricted, such that the welder is working in a forced posture (e.g.: kneeling, sitting, lying) and is touching electrically conductive parts; In workplaces which are restricted completely or in part in terms of electrical conductivity and where there is a high risk through avoidable or accidental touching by the welder; In wet, humid or hot workplaces where the air humidity or sweat signicantly reduces the resistance of human skin and the insu- lating properties or eect of protective equipment. Even a metal conductor or scaolding can create an environment with increased electrical hazard. In this type of environment, insulated mats and pads must be used. Furthermore gauntlet gloves and head protection made of leather or other insulating materials must be worn to insulate the body against Earth. The welding power source must be located outside the working area or electrically conductive surfaces and out of the welder’s reach. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 14472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 14 18.10.2024 10:05:1418.10.2024 10:05:1415GB/IE/NI/CY/MT Additional protection against a shock from the mains current in the event of a fault can be provided by using a fault-circuit inter- rupter, which is operated with a leakage current of no more than 30mA and covers all mains-powered devices in close proximity. Thefault-circuit interrupter must be suitable for all types of current. There must be means of rapid electrical isolation of the welding power source or the welding circuit (e.g. emergency stop device) which are easily accessible. When using welders under electrically dangerous conditions, the output voltage of the welder must not be greater than 113 volt when idling (peak value). Based on the output voltage this welder may be used in these conditions. z Welding in tight spaces When welding in tight spaces this may pose a hazard through toxic gases (risk of suocation). In tight spaces you may only weld if there are trained individuals in the immediate vicinity who can intervene if necessary. In this case, before starting the welding procedure, an expert must carry out an assessment in order to determine what steps are necessary, in order to guarantee safety at work and which precautionary mea- sures should be taken during the actual welding procedure. z Total of no-load voltages When more than one welding power source is operated at the same time, their no-load voltages may add up and lead to an increased electrical hazard. Welding power sources must be connected in such a way that the danger is minimised. The individual welding power sources, with their individual control units and connections, must be clearly marked, in order to be able to identify which device belongs to which welding power circuit. z Using shoulder straps Welding must not take place if the welding power source or the wire feed device is being carried e.g. with a shoulder strap. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 15472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 15 18.10.2024 10:05:1418.10.2024 10:05:1416 GB/IE/NI/CY/MT This is intended to prevent: The risk of losing your balance if the lines or hoses which are connected are pulled The increased risk of an electric shock as the welder comes into contact with the earth if he/she is using a Class I welding power source, the housing of which is earthed through its conductor. z Protective clothing At work, the welder must protect his/her whole body by using appropriate clothing and face protection against radiations and burns. The following steps must be observed: – Wear protective clothing prior to welding work. – Wear gloves. – Open windows to guarantee air supply. – Wear protective goggles. Gauntlet gloves made of a suitable material (leather) must be worn on both hands. They must be in perfect condition. A suitable apron must be worn to protect clothing from ying sparks and burns. When specic work, e.g. overhead welding, isrequired, a protective suit must be worn and, if necessary, even head protection. z Protection against rays and burns Warn of the danger to the eyes by hanging up a sign saying “Caution! Do not look into ames!” in the work area. The work- places must be shielded so that the persons in the vicinity are protected. Unauthorised persons must be kept away from weld- ing work. The walls in the immediate vicinity of xed workplaces should neither be bright coloured or shiny. Windows up to head height must be protected to prevent rays from penetrating or reecting through them, e.g. by using suitable paint. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 16472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 16 18.10.2024 10:05:1418.10.2024 10:05:1417GB/IE/NI/CY/MT z EMC Device Classication According to the standard IEC 60974-10, this is a welder in electro- magnetic compatibility Class A. Class A devices are devices that are suitable for use in all other areas except living areas and areas that are directly connected to a low-voltage supply mains that (also) supplies residential buildings. Class A devices must adhere to the Class A limit values. WARNING NOTICE: Class A devices are intended for use in an industrial environment. Due to the power-related as well as the radiated interference variables, diculties might arise in ensuring electromagnetic compatibility in other environments. Even if the device complies with the emission limit values in accor- dance with the standard, such devices can still cause electromag- netic interference in sensitive systems and devices. The user is responsible for faults caused by the arc while working, and the user must take suitable protective measures. In doing so, the user must consider the following: – network, control, signal and telecommunication lines – computers and other microprocessor-controlled devices – TVs, radios and other playback devices – electronic and electrical safety equipment – people with cardiac pacemakers or hearing aids – measurement and calibration devices – interference immunity of other equipment nearby – the time of day at which the work is being done. The following is recommended to reduce possible interference radi- ation: – equip the mains connection with a mains lter – service the device regularly and keep it in good condition – welding cables should be completely uncoiled and run as close to parallel with the oor as possible – if possible, devices and systems at risk from interference radiation should be removed from the work area or shielded. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 17472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 17 18.10.2024 10:05:1418.10.2024 10:05:1418 GB/IE/NI/CY/MT z Before commissioning Take all parts from the packaging and check whether the ux cored wire welder or parts show any damage. If this is the case, do not use the ux cored wire welder. Contact the manufacturer at the specied service address. Remove all protective lms and other transport packaging. Check whether the delivery is complete. z Assembly z Assembling the welding protection shield Insert the dark welding lens

with the writing facing up into the shield body

(see Fig. C). Thelabelling on the dark welding lens

must now be visible from the front of the protective shield. Push the handle

from the inside into the corresponding notch of the mask, until it snaps into place (see Fig. D). z Inserting the ux cored wire ATTENTION! Always unplug the mains plug from the mains socket prior to each maintenance task or preparatory work in order to prevent the risk of an electric shock, injury or dam- age. PLEASE NOTE! Dierent welding wires will be needed depending on the applica- tion. Welding wires with a diameter of 0.6–1.0 mm can be used with this device. Feed roll, welding nozzle and wire cross-section must be compatible with one another. The device is suitable for wire reels weighing up to maximum 1000 g. Unlock and open the cover of the wire feed unit

by pushing the latch up. Unlock the roller unit by pressing and turning the roller mount

and the washer o the shaft (see Fig. F). PLEASE NOTE! Make sure that the end of the wire does not come loose and cause the roll to roll out on its own. The end of the wire may not be released until during assembly. Completely unpack the ux cored wire welding spool

, so that it can unrolled without diculty. Do not release the wire end yet (see Fig. G). Place the wire reel on the shaft. Make sure that the roll unwinds on the side of the

back on and lock it by pressing and turning it clockwise (see Fig. G). Undo the adjustment screw

and swing it downwards (see Fig. H). Turn the thrust roller unit

to the side (see Fig. I). Loosen the feed roll holder

by turning it anti-clockwise and pull it forwards and o (see Fig. J). On the top of the feed roll

with the specied wire thickness of Ø 0.9mm. The wire must be positioned in the front groove! Erect the feed roll holder

again and screw in a clockwise direction. Remove the torch nozzle

by turning it anti-clockwise (see Fig. K). Unscrew the welding

away from the welder as straight as possible (place it on the oor). Take the wire end out of the edge of the spool (see Fig. L). Trim the wire end with wire scissors or a diagonal cutter in order to remove the damaged, bent ends of the wire (see Fig. L). PLEASE NOTE! The wire must be kept under tension the entire time in order to avoid a releasing and a roll out! Therefore it is recommended to carry out the work with an additional person. Push the ux cored wire through the wire feed guide

(see Fig. M). Guide the wire along the feed roll

and then push it into the wire holder

towards the feed roll

screw (see Fig. O). Set the counter pressure with the adjustment screw. The welding wire must be rmly positioned between the thrust roller and feed roll

in the upper guide without being crushed (see Fig. O). Switch on the welder on the main

switch. Press the torch button

Now the wire feed system pushes the welding wire through the cable assembly

As soon as 1 – 2 cm of the wire protrudes from the torch neck

button again (see Fig. P). Switch o the welder at the main switch. Screw the welding nozzle

back on. Make sure that the welding nozzle

matches the diam- eter of the welding wire used (see Fig. Q). When using the delivered welding wire (Ø 0.9 mm), thewelding nozzle

with the labelling 0.9 mm must be used. Screw the burner nozzle

back onto the torch neck

(see Fig. R). ATTENTION! Always unplug the mains plug from the socket prior to each mainte- nance task or preparatory work in order to prevent the risk of an electric shock, injury or damage. z Commissioning z Switching the device on and o Switch the welder on and o on the main switch

. If you do not intend to use the welder for an extended period, remove the mains plug from the power socket. This is the only way to com- pletely de-energise the device. z Setting the welding current and wire feed The control dial

on the front of the welder can be used to adjust the material thickness to be welded. Power and wire feed are controlled automatically.

The protective device interrupts the overload of the current circuit and the yellow overload protection control lamp

illuminates. Allow the device to cool down (approx. 15 minutes) for the activation of the protection device. Assoon as the yellow overload protection control lamp

goes out, the device is ready for oper- ation again. The protection of the supply lines to the mains sockets must comply with the regulations (VDE0100). Shockproof sockets must be protected to max. 16 A (fuses or circuit breaker) Theuse of higher levels of protection could result in a line re or structural re damage. Welding protection shield HEALTH HAZARD! If you do not use the welding mask, harmful UV radiation and heat emitted by the electric arc could damage your eyes. Always use the welding protection shield for welding work. z Welding ATTENTION! RISK OF BURNS! Welded workpieces are very hot and can cause burns. Always use pliers to move hot, welded workpieces. 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 20472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 20 18.10.2024 10:05:1418.10.2024 10:05:1421GB/IE/NI/CY/MT Please proceed as follows once you have electrically connected the welder: Connect the earthing cable to

the workpiece that is to be welded using the earth clamp. Please ensure good electrical conductivity. The area to be welded on the workpiece must be free of rust and paint. Select the material thickness using the control dial

Switching the device on. Hold the welding protection shield

in front of your face and guide the torch nozzle

to the position on the workpiece that is to be welded. Press the torch button

, in order to generate an arc. Once the arc is burning, the device feeds wire into the weld pool. If the welding lens is big enough, the torch

is slowly guided along the desired edge. The dis- tance between the torch nozzle and workpiece should be as small as possible (it must not be greater than 10 mm). If necessary, oscillate a little to increase the size of the weld pool. The penetration depth (corresponds to the depth of the welding seam in the material) should be as deep as possible without allowing the welding pool to fall through the workpiece. The slag can only be removed from the seam once it has cooled down. To continue welding an interrupted seam: First remove the slag at the starting point. The arc is ignited in the weld groove, guided to the connection point, melted properly and nally the weld seam is continued. CAUTION! Please note that the torch must always be placed on an insulated surface after welding. Always switch o the welder after completing welding work and during breaks and pull the mains plug from the power socket. z Creating a weld seam Forehand welding Push the torch forwards. Result: The penetration depth is lower, broader weld width, atter weld bead (visible surface of the seam) and greater fusion error tolerance. Backhand welding The torch is dragged from the weld seam (Fig. S). Result: Greater penetration depth, narrower weld width, higher weld bead and lower fusion error tolerance. Welded joints There are two-basic types of joints in welding: Butt welds (outer edge) and angle welding (inner edge and overlapping). Butt welds With butt welds of up to 2 mm material thickness, the weld edges are completely brought together. For greater thicknesses, a gap of 0.5–4 mm must be selected. The ideal gap depends on the welded material (aluminium or steel), the material composition as well as the type of welding selected. This gap should be determined by welding on a sample workpiece. Flat butt welds Welds should be made without interruption and with a sucient penetration depth. Therefore, it is extremely important to be well prepared. The quality of the weld result is aected by: the amperage, 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 21472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 21 18.10.2024 10:05:1418.10.2024 10:05:1422 GB/IE/NI/CY/MT the gap between weld edges, the inclination of the torch and the diameter of the welding wire. The steeper you hold the torch against the workpiece, the higher the penetration depth and vice versa.

To forestall or reduce deformations that can happen during the material hardening process, it is good to x the workpiece with a device. Avoid stiening the welded structure to prevent cracks in the weld. These problems can be avoided if there is a possibility of turning the workpiece so that the weld can be carried out in two passes running in opposite directions. Welds on the outer edge The preparation for this is very simple (Fig. T, U).

However, it is no longer expedient for thicker materials. In this case, it is better to prepare a joint as shown below, in which the edge of the plate is angled (Fig. V).

Fillet weld connections A llet weld is created if the workpieces are perpendicular to each other. The weld should be shaped like a triangle with sides of equal length and a slight llet (Fig. W, X). 472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 22472024_2407_Inverter-Fülldrahtschweißgerät_LB8_content.indb 22 18.10.2024 10:05:1418.10.2024 10:05:1423GB/IE/NI/CY/MT Welds on an inner edge The preparation for this weld joint is very simple and is carried out for thicknesses of 5 mm. Thedimension “d” needs to be reduced to a minimum and should always be less than 2 mm (Fig. W).

However, it is no longer expedient for thicker materials. In this case, it is better to prepare a joint as shown in Figure V, in which the edge of the plate is angled.

Overlap welds The most common preparation is that with straight weld edges. The weld can be released using a standard angle weld seam. Both workpieces must be brought as close to each other as possible, asshown in Fig. Y.
