• Arc welding creates sparks, melted metal parts and smoke, therefore observe the following: Remove all flammable substances and/or materials from the workplace.

• Make sure that there is a sufficient air supply available.

• Do not weld on containers, vessels or pipes that have contained flammable liquids or gases. Avoid direct contact with the welding circuit. The off-load voltage arising between the electrode holder and the earthing clamp can be dangerous.

• Do not store or use the device in a damp or wet environment or in the rain

• Protect your eyes with specially designed protective glass (DIN grade 9-10). Use gloves and dry protective clothing that is free from oil and grease so that the skin is not exposed to the ultraviolet rays from the arc.

• Do not use the welding machine to thaw pipes. Note!

• The light rays from the arc can damage the eyes and cause burns to the skin.

• Arc welding creates sparks and droplets of melted metal, the welded work piece begins to smoulder and remains very hot for a relatively long time.

• Arc welding releases vapours that are potentially harmful. Any electric shock can be potentially fatal.

• Do not come within 15 m of the arc.

• Protect yourself (and bystanders) in the vicinity from the potentially hazardous effects of the electric arc.

• Warning: Depending on the conditions of the mains power connection at the welding machine connection point, this can lead to disturbances in the mains for other consumers. Attention! Overloaded mains supplies and circuits can cause disturbances for other consumers while welding. In case of doubt, the electricity supplier is to be consulted.

5. Safety information

m WARNING! Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Always observe m ATTENTION! Only use the device as per its suitability, which is listed in these instructions. Improper handling of this system can be dangerous for persons, animals and property. The system user is responsible for their own safety and that of other persons:

• Always read these usage instructions and observe the regulations.

• Repairs and/or maintenance work may only be carried out by qualified persons.

• Only the welding cables included in the scope of delivery or accessories recommended by the manufacturer may be used.

• Ensure that the device is looked after appropriately

• The device must not be constrained or stood directly against the wall during its functional life so that sufficient air can always be taken in through the opening slits. Make sure that the device is connected properly to the mains. Avoid any tensile stress on the mains cable. Unplug the device before setting it up in another location.

• Pay attention to the condition of the welding cable, the electrode holder and the earth clamp, wear on the insulation or on the parts carrying the electrical power can lead to a hazardous situation and reduce the quality of the welding work.www.scheppach.com

• Wear full body protection.

• It must be ensured that the protective conductor in electrical systems or devices can be destroyed by the welding current in the event of negligence, e.g. the earth clamp is placed on the welding machine housing which is connected to the protective conductor of the electrical system. The welding work is carried out on a machine with a protective conductor connection. It is therefore possible to weld to the machine without having to attach the earth clamp to it. In this case, the welding current flows from the earth clamp to the machine via the protective conductor. The high welding current can cause melting through of the protective conductor.

• The fusing of the supply lines to the mains sockets must correspond to the regulations. Only fuses and automatic devices corresponding to the cable cross-section may be used in accordance with these regulations. Over-fusing can cause a line fire or fire damage to the building.

• Do not use the welding device in the rain.

• Do not use the welding device in a humid environment.

• 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. 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.

• Work on the mains voltage side, e.g. on cables, connectors, sockets, etc., may only be carried out by a specialist. This applies in particular when creating intermediate cables.

• In the event of an accident, disconnect the welding power source from the mains immediately.

• If electrical contact voltages occur, switch off the device immediately and have it checked by a specialist.

• Always ensure that the electrical contacts on the welding current side are good.

• Always wear insulated gloves on both hands when welding. These protect rays electric shocks (off-load voltage of the welding current circuit), harmful rays (heat and UV rays) and smouldering metal and slag splashes.

• Wear sturdy, insulated footwear; the shoes should also insulate when wet. Low shoes are not suitable as smouldering metal drops that fall cause burns.

• Wear suitable clothing, no synthetic clothing.

• Do not look into the arc with unprotected eyes, only use a welding shield with protective glass in accordance with DIN. The arc also emits UV rays in addition to light and heat rays which cause glare and burns. These invisible ultraviolet rays cause very painful conjunctivitis that is only noticeable a few hours later if the protection is insufficient. Furthermore, UV rays cause harmful, sunburn-like effects to unprotected parts of the body.

• Also, persons in the vicinity of the electric arc must be advised of the hazard and equipped with the necessary protective equipment. Protective partitions or walls may have to be erected.

• When welding, especially in small rooms, ensure that there is a sufficient supply of fresh air as smoke and harmful gases form.

• Welding work may not be carried out on containers in which gases, fuels, mineral oils or the like are stored, even if they have been empty for a long period as there is a risk of explosion due to residues.

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

• Welded joints that are exposed to high stresses and must meet safety requirements may only be carried out by specially trained and certified welders. Examples are: Pressure vessels, rails, trailer couplings, etc.

• Arc rays can damage the eyes and the skin. Wear a hat and safety goggles.

• Wear hearing protection and shirts with high, closed collars.

• Wear welding helmets and ensure that the filter settings are appropriate.www.scheppach.com

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 residual current circuit breaker shall be suitable for all types of current. Means for rapid electrical disconnection of the welding current source or welding current circuit (e.g. emergency 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 persons who can intervene if necessary, are in the immediate vicinity. Here, an assessment by an expert must be carried out before the welding process begins to determine 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 power source is worn, e.g. with a shoulder sling. This is to prevent:

• The risk of losing balance when pulling connected cables or hoses.

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

• Always make sure that the welding mask is functioning 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 may only be operated by persons who are aged 16 and above.

• 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. Failure 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 electrical 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 restricted so that the welder works in an enforced posture (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 protective equipment. A metal ladder or scaffolding can also create an environment with increased electrical hazards. 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.www.scheppach.com

• 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.

• Equipment and installations at risk from disruptive radiation should be removed from the welding area if possible or shielded.

• Using an electromagnetic lter that reduces electromagnetic interference. General safety measures The user is responsible for installing and using the device properly in accordance with the instructions of the manufacturer. If electromagnetic interference is identified, it is the responsibility of the user to eliminate it using the technical aids mentioned above under point “Important note on the power connection”. Warning! This power tool generates an electromagnetic field during operation. This field can impair active or passive medical implants under certain conditions. 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. Protective clothing

• During the work, the welder must be protected against rays and burns by clothing over their entire body and face protection.

• Gauntlets made of a suitable material (leather) must be worn on both hands. They must be in perfect condition.

• Suitable aprons must be worn to protect clothing from flying sparks and burns. If the type of work requires it, e.g. overhead welding, an overall and, if necessary, head protection must be worn.

• The protective clothing and all accessories used must correspond to the “Personal Protective Equipment” directive. Protection from rays and burns

• Advise of the danger to the eyes with a note saying “Caution, do not look into the flames!” at the place of work. Workplaces must be shielded as much as possible so that persons in the vicinity are protected. Unauthorised persons must be kept away from the welding work

• The walls should not be light-coloured or glossy in the immediate vicinity of fixed workplaces. Windows must not allow rays through and be secured against the reflection of rays at least up to head height, e.g. using a suitable coat of paint. EMC equipment classification ACHTUNG! This class A device is not intended for use in residential environments 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 limits in accordance with the standard, arc welding equipment may still cause electromagnetic interference in sensitive systems and devices. The user is responsible for interference caused by the arc during welding and the user must take appropriate protective measures. The user must pay particular attention to the following:

• Mains, control, signal and telecommunication lines

• Computers and other microprocessor-controlled

• Television, radio and other playback equipment

• Electronic and electrical safety deviceswww.scheppach.com

• 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

• Once the arc is lit, the device feeds wire into the weld pool. If the spot is large enough, guide the burner slowly along the desired edge. The distance between the burner nozzle and the workpiece should be kept as short as possible (never larger than 10 mm). If necessary, swing the burner nozzle slightly in order to enlarge the weld pool a little.

• For those with little experience, the initial difficulty lies in creating a stable electric arc.

• The optimum setting of the welding current and wire feed rate is made automatically by the device.

• The penetration depth should be as deep as possible but the weld pool should not drop through the workpiece.

• The slag should only be removed from the seam once it has cooled. If continuing with an interrupted weld seam, the slag should first be removed from the point of attachment. The electric arc is struck in the weld groove, guided to the connection point, properly melted there and then continued along the weld seam.

• Attention! Always used tongs to move hot, welded workpieces. Ensure that the burner is always set down on an insulated surface after welding. Always switch the welding machine off and pull out the plug after the welding work is complete and during breaks. Overheating protection The welding machine is equipped with overheating protection which protects the welding transformer from overheating. If the overheating protection reacts, the indicator lamp (2) lights up on your device. Allow the welding machine to cool down for a while. Replacing the mains connection cable Danger! If the power cord of this device is damaged, it must be replaced by the manufacturer, their service department or a similarly qualified person to avoid dangers.

10. Electrical connection
