• Arc welding generates sparks, molten metal par- ticles and smoke, so the following is required: Re- move all inflammable substances and/or materials from the working area.

• Ensure that there is adequate ventilation.

• Do not weld on tanks, vessels or pipes that have contained inflammable liquids or gases. Avoid all direct contact with the welding circuit; the idling voltage between the electrode tongs and the earth terminal may be dangerous.

• Do not store or use the appliance in wet or damp conditions or in the rain.

• Protect your eyes with specially designed goggles (DIN Grad 9-10). Wear gloves and dry safety cloth- ing that are not contaminated by any oil or grease to ensure that your skin is not exposed to ultraviolet radiation from the arc.

• Do not use this welder to defrost pipes Remember!

• The radiation from the arc can damage your eyes and cause burns on skin.

• Arc welding generates sparks and droplets of molten metal; the welded workpiece may start to glow and will remain very hot for a relatively long period of time.

• Arc welding releases vapors that may be harmful. Every electric shock is potentially fatal.

• Do not approach the arc within a radius of 15 m un- protected.

• Protect yourself (and others around you) against the possible hazardous effects of the arc.

• Warning: Depending on the mains connection con- ditions at the connection point of the welding set, other consumers connected to the mains may suffer faults. Attention! If the supply mains and circuits are overloaded, other consumers may suffer interference during the welding work. If you have any doubts, contact your electricity supply company. Sources of danger during arc welding Arc welding results in a number of sources of danger. It is therefore particularly important for the welder to comply with the following rules so as not to place him- self or others in danger and to avoid endangering peo- ple and equipment. The device may only be operated by qualied or in- structed personnel. This includes persons who, due to their technical training, experience and knowledge of the relevant facilities, are able to assess the work assigned to them and recognize possible dangers or persons who are responsible for the assigned work and have been instructed about possible dangers due to careless behaviour. Please observe that our equipment was not designed with the intention of use for commercial or industrial purposes. We assume no guarantee if the equipment is used in commercial or industrial applications, or for equivalent work.

m WARNING! Read all safety warnings, instruc- tions, illustrations and specications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, re and/or se- rious injury. Please note m ATTENTION Use this equipment only for the purpose for which it is designed, as described in these instructions. Handling this system incorrectly may be hazardous for persons, animals and property. The user of this system is responsible for his/her own safety and for the safety of others:

• Read these operating instructions and follow all the regulations.

• Repairs and/or maintenance work must be left strict- ly to qualified personnel.

• Only the welding cables supplied with the equipment and the accessories recommended by the manufac- turer are allowed to be used.

• Ensure that the appliance is looked after properly.

• To ensure that sufficient air can be drawn in through the ventilation slits, the appliance should not be con- stricted or placed next to a wall while it is operating. Make sure that the appliance is correctly connected to the mains supply. Do not subject the mains lead to any tensile stress. Unplug the appliance before you change its position.

• Check the condition of the welding cables, the elec- trode tongs and the earth terminals; wear on the insulation and the live parts may result in danger- ous conditions and reduce the quality of the welding work.www.scheppach.com

• Arc beams can damage your eyes and injure your skin. Wear a helmet and safety goggles.

• Wear hearing protection and high, closed shirt col- lars.

• Wear welding safety helmets and make sure you use the appropriate filter settings.

• It must be noted that the protective conductor in electrical systems of appliances may be destroyed by the welding current in the event of negligence, for example if the earth terminal is placed on the welding set casing to which the protective conductor of the electrical system is connected. The welding work is completed on a machine with a protective conductor connection. It is therefore possible to weld on the machine without having connected the earth terminal to it. In this case the welding current will flow from the earth terminal through the protec- tive conductor to the machine. The high welding current may cause the protective conductor to melt.

• The fuses on the supply cables to the mains sock- ets must comply with the relevant regulations. To comply with these regulations, only fuses or circuit breakers suitable for the cross-section of the cables may be used. The use of too high a fuse may result in the cable burning and fire damage to the building.

• Do not use the welding device in the rain.

• Do not use the welding device in a humid environ- ment.

• Only set up the welding device on a flat surface.

• The output is rated at an ambient temperature of 20°C. The welding time may be reduced at higher temperatures. Danger due to 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 electrode with bare hands. Do not wear wet or damaged gloves. Protect yourself from electric shock by insulating against the workpiece. Do not open the housing of the device. Danger due to welding fumes Inhalation of welding fumes can be hazardous to health. Do not hold your head in the fumes. Use equipment in open areas. Use ventilation to remove the smoke.

• Have all work on the mains voltage system, for ex- ample on cables, plugs, sockets, etc., performed only by trained electricians. This particularly applies to configuring intermediate cables.

• If an accident occurs, disconnect the welding power source from the mains immediately.

• If electric touch voltages occur, switch off the weld- ing set immediately and have it checked by an ex- pert.

• Always check for good electrical contacts on the welding current side.

• Wear insulating gloves on both hands for welding. These offer protection from electric shocks (idling voltage in the welding circuit), harmful radiation (Heat and UV radiation) and from glowing metal and slag spatter.

• Wear firm, insulated footwear. Your shoes should also protect you in wet conditions. Open toe foot- wear is not suitable since falling droplets of glowing metal will cause burns.

• Wear suitable clothing, do not wear synthetic clothes.

• Do not look into the arc with unprotected eyes, use only a welding safety shield with the proper safety glass in compliance with DIN standards. In addition to light and heat, which may cause dazzling and burns, the arc also gives off UV radiation. Without proper protection, this invisible ultraviolet radiation causes very painful conjunctivitis, which will only be noticeable several hours later. In addi- tion, UV radiation will cause sunburn-type symp- toms on unprotected parts of the body.

• Personnel or assistants in the vicinity of the arc must also be notified of the dangers and provided with the required protection; if necessary install safety walls.

• Ensure adequate ventilation for welding, particularly in small rooms since the process causes smoke and harmful gases.

• Do not carry out any welding work on tanks that have been used to store gases, fuels, mineral oil or the like, even if they have been empty for a lengthy pe- riod of time, since any residue will result in a danger of explosion.

• Special regulations apply in areas where there is a potential risk of fire and/or explosion.

• Welds that are exposed to large stresses and must comply with safety requirements may only be com- pleted by specially trained and approved welders. Examples of such welds include pressure vessels, rails, trailer hitches, etc.www.scheppach.com

In such environments, use insulated pads and shims. Also, gauntlet-style gloves and headgear made of leather or other insulating material should be worn to insulate the body from earth. The welding power source must be located outside the work area or electrically conductive surfaces and out of reach of the welder. Additional protection against shock from mains current in the event of a fault may be provided by the use of a residual current circuit breaker operating at a leakage current not exceeding 30 mA and supplying all mains operated equipment in the vicinity. The fault-circuit in- terrupter must be suitable for all types of current. Means for rapid electrical disconnection of the welding current source or welding current circuit (e.g. emergen- cy stop device) shall within easy reach. When welding equipment is used in electrically hazardous conditions, the output voltage of the welding equipment shall not exceed 113 V (peak value) under no-load conditions. This welding equipment may be used in these cases because of the output voltage. Welding in confined spaces When welding in confined spaces, there may be a risk of toxic gases (danger of suffocation). Welding may only be carried out in confined spaces if instructed per- sons who can intervene if necessary, are in the imme- diate vicinity. Here, an assessment by an expert must be carried out before the welding process begins to de- termine which steps are necessary to ensure the safety of the work and which precautionary measures should be taken during the actual welding process. Summation of open circuit voltages If more than one welding power source is in operation at the same time, their open-circuit voltages can add up and lead to an increased electrical hazard. Welding power sources must be connected in such a way that this hazard is minimised. The individual welding power sources, with their separate controls and connections, must be clearly marked to indicate what belongs to which welding circuit. Use of shoulder slings Welding shall not be carried out while the welding pow- er source is worn, e.g. with a shoulder sling. This is to prevent:

• The risk of losing balance when pulling connected cables or hoses. Danger due to welding sparks Welding sparks can cause an explosion or fire. Keep flammable materials away from welding. Do not weld next to flammable materials. Welding sparks can cause fires. Keep a fire extinguisher nearby and an observer who can use it immediately. Do not weld on drums or any closed containers. Safety instructions specific to welding masks

• Always make sure that the welding mask is func- tioning properly by using a bright light source (e.g. lighter) before starting welding work.

• Welding spatter can damage the protective panel. Replace damaged or scratched protective panels immediately.

• Replace damaged or heavily soiled or splattered components immediately.

• The device must only be operated by people over the age of 16.

• Familiarise yourself with the safety instructions for welding. Also observe the safety instructions for your welding device.

• Always put on the welding mask when welding. Fail- ure to do so may result in serious retinal injuries.

• Always wear protective clothing when welding.

• Never use the welding mask without a protective panel.

• Replace the protective panel in good time for good visibility and fatigue-free working. Environment with increased electrical hazards When welding in environments with increased electri- cal hazards, the following safety instructions must be observed. Environments with increased electrical hazards can be found, for example:

• At workplaces where the range of movement is re- stricted so that the welder works in an enforced pos- ture (e.g. kneeling, sitting, lying down) and touches electrically conductive parts;

• At workplaces which are wholly or partially bounded by electrically conductive parts and where there is a high risk of avoidable or accidental contact by the welder;

• In wet, humid or hot workplaces where humidity or perspiration significantly reduces the resistance of human skin and the insulating properties or protec- tive equipment. A metal ladder or scaffolding can also create an envi- ronment with increased electrical hazards.www.scheppach.com

The user must pay particular attention to the following:

• Mains, control, signal and telecommunication lines

• Computers and other microprocessor-controlled devices

• Television, radio and other playback equipment

• Electronic and electrical safety devices

• Persons with pacemakers or hearing aids

• Measuring and calibration equipment

• Immunity of other equipment in the vicinity

• The time of day when the welding work is carried out. In order to reduce possible interference radiation, it is recommended:

• Set up and operate the welding device properly to minimise possible disruptive emissions.

• Maintain the welding device regularly and keep it in good condition.

• Welding cables should be fully unwound and run parallel to the oor insofar as possible

• Devices and systems that are compromised by the interference radiation must be removed from the welding area or shielded.

• Using an electromagnetic lter that reduces electro- magnetic interference. General safety information It is the user’s responsibility to install and use the equipment properly in accordance with the instruc- tions issued by the manufacturer. If electromagnetic interference is noticed, it is the user’s responsibility to eliminate said interference with the technical devices mentioned in the section “Important information about the power connection”. Reduction of emissions Main current supply The welder must be connected to the main current sup- ply in accordance with the instructions issued by the manufacturer. If interference occurs, it may be neces- sary to introduce additional measures, e.g. fitting a fil- ter to the main current supply (see above in the section “Important information about the power connection”). The welding cables should be kept as short as pos- sible. Warning! This power tool generates an electromag- netic field during operation. This field can impair active or passive medical implants under certain conditions.

• The increased risk of electric shock due to the weld- er coming into contact with earth when using a Class I welding power source whose housing is earthed by its protective earth conductor. Safety clothing

• While working, the welder must protect his entire body from radiation and burns by wearing suitable clothing and a face guard.

• Slip-on gloves made of a suitable material (leather) must be worn on both hands. They must be in per- fect condition.

• Suitable aprons must be worn to protect clothing from sparks and burns. A safety suit and, if neces- sary, head protection must be worn if required by the type of work in question, e.g. overhead welding.

• The protective clothing used as well as all accesso- ries must be in compliance with the “Personal safety equipment” EU Directive. Protection from radiation and burns

• Provide information about the risk to eyes at the working site in the form of a poster with the wording “Caution – do not look at the flames”. Workplaces are to be screened off wherever possible so that personnel in the vicinity are protected. Unauthorized persons are to be kept away from the welding work.

• The walls in the immediate vicinity of stationary workplaces should not have a light color or a sheen. Windows up to head height are to be protected against radiation passing through them or reflecting off them, for example by coating them with a suitable paint. EMV device classification ATTENTION! This class A device is not intended for use in residential environ- ments in which the power supply comes from a public low-voltage supply system. It can be di󰀩cult to ensure electromagnetic compatibility in these areas, both due to conducted and radiated high-frequency interferences. Even if the welding device complies with the emission limit values of the standard, arc welding devices can still result in electromagnetic interferences in sensitive systems and devices. The user is responsible for inter- ference caused by the arc during welding and the user must take appropriate protective measures.www.scheppach.com

equipment Fitting the carrying strap (Fig. B) Attach the carrying strap (11) as shown in Fig. B. Installing the welding shield (Fig. C + D)

• Install the handle (14) on the welding shield (13) as shown in Fig. D.

• Install the protective glass (15) on the welding shield (13) as shown in Fig. D.

• Then fold the three sides of the welding shield. The two sides each connect to the top with two press studs. Before starting the equipment Connecting to the mains power supply Before you connect the power cable (8) to the mains power supply, make sure that the data on the rating plate is the same as that for your mains supply. Connect the machine to a properly installed protec- tive contact socket, with at least 16A circuit breaker. Danger! The mains plug may only be replaced by a qualified electrician. Connecting the welding cable (Fig. E) Danger! Always make sure the device is unplugged before carrying out any connection work on the weld- ing cable (9+10)! Connect the welding cable as shown in Fig. E. To do so, connect the two connectors on the electrode holder (9) and the ground terminal (10) to the corre- sponding quick-lock couplings (6/7) and lock the con- nectors in place by turning them in a clockwise direc- tion. The cable with the electrode holder (9) is normally con- nected to the positive pole (6) and the cable with the ground terminal (10) to the negative pole (7). Welding preparations Connect the earth terminal (10) direct to the part to be welded or to the support on which the part is resting. Ensure that the earth terminal is in direct contact with the part to be welded. You should therefore avoid coat- ed surfaces and/or insulated materials. The electrode holder cable has a special clamp at one end, which is used to secure the electrode. In order to prevent the risk of serious or deadly injuries, we recommend that persons with medical implants consult with their physician and the manufacturer of the medical implant prior to operating the power tool.

• If possible, keep the packaging until the expiry of the warranty period. ATTENTION The device and the packaging are not children‘s toys! Do not let children play with plastic bags, films or small parts! There is a danger of choking or suffocating!www.scheppach.com

As soon as the arc has ignited, attempt to keep it a distance from the workpiece equivalent to the diameter of the electrode. This distance should be kept as constant as possible during the welding process. The angle of the electrode in the direction in which you are working should be 20/30°. Always use tongs to remove spent electrodes and to move parts that you have just welded. Please note that the electrode holder (9) must always be put down so that it is insulated after you have completed the welding work. Do not remove the slag until the weld has cooled. If you want to continue a weld after an interruption, the slag from your initial attempt must first be removed. Overheating guard The welding set is fitted with an overheating guard that protects the welding transformer from overheating. If the overheating guard trips, the control lamp (5) on your set will be lit. Allow the welding set to cool for a time. Replacing the power cable Danger! If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel to avoid danger.

10. Electrical connection

The customer‘s mains connection as well as the extension cable used must also comply with these regulations. Damaged electrical connection cable The insulation on electrical connection cables is of- ten damaged. This may have the following causes:

• Passage points, where connection cables are passed through windows or doors.

• Kinks where the connection cable has been improp- erly fastened or routed.

• Places where the connection cables have been cut due to being driven over.

• Insulation damage due to being ripped out of the wall outlet.

• Cracks due to the insulation ageing. Such damaged electrical connection cables must not be used and are life-threatening due to the insulation damage. The welding safety shield must be used at all times for welding. It protects your eyes from the radiation emit- ted by the arc and nevertheless enables you to watch the welding process.

9. Initial operation

Switching ON/OFF (Fig. A) Switch on the machine by moving the On/Off switch (1) to the “I” position. The indicator lamp for operation (4) then comes on. Switch off the machine by moving the On/Off switch (1) to the “0” position. The indicator lamp for operation (4) then goes out. Welding (Fig. A + E) Connect all the electrical connections for the power supply and for the welding current circuit. Most coated electrodes are connected to the positive pole. Howev- er, some types of electrode have to be connected to the negative pole. Ensure that you observe the information supplied by the manufacturer in relation to the type of electrode and correct polarity. Fit the welding cables (9/10) to the quick-lock couplings (6/7) accordingly. Then fasten the unsheathed end of the electrode in the electrode holder (9) and connect the ground terminal (10) to the part you wish to weld. Ensure that a good electric contact is made. Switch on the device and set the welding current, depending on the electrode used, using the potentiometer (2). Hold the safety shield in front of your face and rub the tip of the electrode on the part you wish to weld as if you were striking a match. This is the best method of ig- niting an arc. Check that you have the correct electrode and current strength on a test part. Note: See the following table for information on the welding current to be used, depending on the electrode diameter. Electrode (Ø mm): Welding current (A)
