    1. Safety rules

    Mains connection

    Devices with a higher rating may affect the energy quality of the mains due to their current consumption.

    This may affect a number device types in terms of:
    • Connection restrictions
    • Criteria with regard to the maximum permissible mains impedance *)
    • Criteria with regard to the minimum short-circuit power requirement *)

    *) at the interface with the public grid
    see "Technical data"

    In this case, the plant operator or the person using the device should check whether the device may be connected, where appropriate by discussing the matter with the power supply company.

    IMPORTANT! Ensure that the mains connection is earthed properly

    1. Safety rules

    Protecting yourself and others

    Anyone working with the device exposes themselves to numerous risks, e.g.
    • flying sparks and hot pieces of metal
    • Arc radiation, which can damage eyes and skin
    • Hazardous electromagnetic fields, which can endanger the lives of those using cardiac pacemakers
    • Risk of electrocution from mains current and welding current
    • Greater noise pollution
    • Harmful welding fumes and gases
    Suitable protective clothing must be worn when working with the device. The protective clothing must have the following properties:
    • Flame-resistant
    • Insulating and dry
    • Covers the whole body, is undamaged and in good condition
    • Safety helmet
    • Trousers with no turn-ups
    Protective clothing refers to a variety of different items. Operators should:
    • Protect eyes and face from UV rays, heat and sparks using a protective visor and regulation filter
    • Wear regulation protective goggles with side protection behind the protective visor
    • Wear stout footwear that provides insulation even in wet conditions
    • Protect the hands with suitable gloves (electrically insulated and providing protection against heat)
    • Wear ear protection to reduce the harmful effects of noise and to prevent injury
    Keep all persons, especially children, out of the working area while any devices are in operation or welding is in progress. If, however, there are people in the vicinity:
    • Make them aware of all the dangers (risk of dazzling by the arc, injury from flying sparks, harmful welding fumes, noise, possible risks from mains current and welding current, etc.)
    • Provide suitable protective equipment
    • Alternatively, erect suitable safety screens/curtains.
    1. Safety rules

    Noise emission values

    The device generates a maximum sound power level of <80 dB(A) (ref. 1pW) when idling and in the cooling phase following operation at the maximum permissible operating point under maximum rated load conditions according to EN 60974-1.

    It is not possible to provide a workplace-related emission value during welding (or cutting) as this is influenced by both the process and the environment. All manner of different welding parameters come into play, including the welding process (MIG/MAG, TIG welding), the type of power selected (DC or AC), the power range, the type of weld metal, the resonance characteristics of the workpiece, the workplace environment, etc.

    1. Safety rules

    Danger from toxic gases and vapours

    The fumes produced during welding contain harmful gases and vapours.

    Welding fumes contain substances that cause cancer, as stated in Monograph 118 of the International Agency for Research on Cancer.

    Use at-source extraction and a room extraction system.
    If necessary, use a welding torch with an integrated extraction device.

    Keep your face away from welding fumes and gases.

    Fumes and hazardous gases
    • must not be breathed in
    • must be extracted from the working area using appropriate methods.

    Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate of at least 20 m³ per hour at all times.

    Otherwise, a welding helmet with an air supply must be worn.

    If there is any doubt about whether the extraction capacity is sufficient, the measured toxic emission values should be compared with the permissible limit values.

    The following components are responsible, amongst other things, for the degree of toxicity of welding fumes:
    • Metals used for the workpiece
    • Electrodes
    • Coatings
    • Cleaners, degreasers, etc.
    • Welding process used

    The relevant material safety data sheets and manufacturer's specifications for the listed components should therefore be studied carefully.

    Recommendations for trade fair scenarios, risk management measures and for identifying working conditions can be found on the European Welding Association website under Health & Safety (https://european-welding.org).

    Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radiation area.

    Close the shielding gas cylinder valve or main gas supply if no welding is taking place.

    1. Safety rules

    Danger from flying sparks

    Flying sparks may cause fires or explosions.

    Never weld close to flammable materials.

    Flammable materials must be at least 11 metres (36 ft. 1.07 in.) away from the arc, or alternatively covered with an approved cover.

    A suitable, tested fire extinguisher must be available and ready for use.

    Sparks and pieces of hot metal may also get into adjacent areas through small gaps or openings. Take appropriate precautions to prevent any danger of injury or fire.

    Welding must not be performed in areas that are subject to fire or explosion or near sealed tanks, vessels or pipes unless these have been prepared in accordance with the relevant national and international standards.

    Do not carry out welding on containers that are being or have been used to store gases, propellants, mineral oils or similar products. Residues pose an explosive hazard.

    1. Safety rules

    Risks from mains current and welding current

    An electric shock is potentially life threatening and can be fatal.

    Do not touch live parts either inside or outside the device.

    During MIG/MAG welding and TIG welding, the welding wire, the wire spool, the feed rollers and all pieces of metal that are in contact with the welding wire are live.

    Always set the wirefeeder up on a sufficiently insulated surface or use a suitable, insulated wirefeeder holder.

    Make sure that you and others are protected with an adequately insulated, dry base or cover for the earth or ground potential. This base or cover must extend over the entire area between the body and the earth or ground potential.

    All cables and leads must be secured, undamaged, insulated and adequately dimensioned. Replace loose connections and scorched, damaged, or inadequately dimensioned cables and leads immediately.
    Use the handle to ensure the power connections are tight before every use.
    In the case of power cables with a bayonet connector, rotate the power cable around the longitudinal axis by at least 180° and pretension.

    Do not wrap cables or leads around the body or parts of the body.

    The electrode (rod electrode, tungsten electrode, welding wire, etc.) must
    • never be immersed in liquid for cooling
    • never be touched when the welding system is switched on.

    Double the open circuit voltage of a welding system can occur between the welding electrodes of two welding systems. Touching the potentials of both electrodes at the same time may be fatal under certain circumstances.

    Arrange for the mains cable to be checked regularly by a qualified electrician to ensure the ground conductor is functioning properly.

    Protection class I devices require a mains supply with ground conductor and a connector system with ground conductor contact for proper operation.

    Operation of the device on a mains supply without ground conductor and on a socket without ground conductor contact is only permitted if all national regulations for protective separation are observed.
    Otherwise, this is considered gross negligence. The manufacturer shall not be held liable for any damage arising from such usage.

    If necessary, provide adequate earthing for the workpiece.

    Switch off unused devices.

    Wear a safety harness if working at height.

    Before working on the device, switch it off and pull out the mains plug.

    Attach a clearly legible and easy-to-understand warning sign to the device to prevent anyone from plugging the mains plug back in and switching it on again.

    After opening the device:
    • Discharge all live components
    • Ensure that all components in the device are de-energised.

    If work on live parts is required, have a second person switch off the main switch at the right moment.

    1. Safety rules

    Meandering welding currents

    If the following instructions are ignored, meandering welding currents can develop with the following consequences:
    • Fire hazard
    • Overheating of parts connected to the workpiece
    • Damage to ground conductors
    • Damage to device and other electrical equipment

    Ensure that the workpiece is held securely by the workpiece clamp.

    Attach the workpiece clamp as close as possible to the area that is to be welded.

    Position the device with sufficient insulation against electrically conductive environments, such as insulation against conductive floor or insulation to conductive racks.

    If power distribution boards, twin-head mounts, etc., are being used, note the following: The electrode of the welding torch / electrode holder that is not used is also live. Make sure that the welding torch / electrode holder that is not used is kept sufficiently insulated.

    In the case of automated MIG/MAG applications, ensure that only an insulated wire electrode is routed from the welding wire drum, large wirefeeder spool or wirespool to the wirefeeder.

    1. Safety rules

    EMC Device Classifications

    Devices in emission class A:
    • Are only designed for use in industrial settings
    • Can cause line-bound and radiated interference in other areas
    Devices in emission class B:
    • Satisfy the emissions criteria for residential and industrial areas. This is also true for residential areas in which the energy is supplied from the public low-voltage mains.

    EMC device classification as per the rating plate or technical data.

    1. Safety rules

    EMC measures

    In certain cases, even though a device complies with the standard limit values for emissions, it may affect the application area for which it was designed (e.g. when there is sensitive equipment at the same location, or if the site where the device is installed is close to either radio or television receivers).
    If this is the case, then the operator is obliged to take appropriate action to rectify the situation.

    Check and evaluate the immunity to interference of nearby devices according to national and international regulations. Examples of equipment that may be susceptible to interference from the device include:
    • Safety devices
    • Network, signal and data transfer lines
    • IT and telecommunications devices
    • Measuring and calibrating devices
    Supporting measures for avoidance of EMC problems:
    1. Mains supply
      • If electromagnetic interference arises despite the correct mains connection, additional measures are necessary (e.g. use of a suitable line filter)
    2. Welding power-leads
      • must be kept as short as possible
      • must be laid close together (to avoid EMF problems)
      • must be kept well apart from other leads
    3. Equipotential bonding
    4. Earthing of the workpiece
      • If necessary, establish an earth connection using suitable capacitors.
    5. Shield, if necessary
      • Shield other devices nearby
      • Shield the entire welding installation
    1. Safety rules

    EMF measures

    Electromagnetic fields may pose as yet unknown risks to health:
    • Effects on the health of persons in the vicinity, e.g. those with pacemakers and hearing aids
    • Individuals with pacemakers must seek advice from their doctor before approaching the device or any welding that is in progress
    • For safety reasons, maintain as large a distance as possible between the welding power-leads and the head/torso of the welder
    • Do not carry welding power-leads and hosepacks over the shoulders or wind them around any part of the body
    1. Safety rules

    Specific hazards

    Keep hands, hair, clothing and tools away from moving parts. For example:
    • Fans
    • Cogs
    • Rollers
    • Shafts
    • Wire spools and welding wires

    Do not reach into the rotating cogs of the wire drive or into rotating drive components.

    Covers and side panels may only be opened/removed while maintenance or repair work is being carried out.

    During operation
    • Ensure that all covers are closed and all side panels are fitted properly.
    • Keep all covers and side panels closed.

    The welding wire emerging from the welding torch poses a high risk of injury (piercing of the hand, injuries to the face and eyes, etc.).
    Therefore, always keep the welding torch facing away from the body (devices with wirefeeder) and wear suitable protective goggles.

    Never touch the workpiece during or after welding - risk of burns.

    Slag can jump off cooling workpieces. The specified protective equipment must therefore also be worn when reworking workpieces, and steps must be taken to ensure that other people are also adequately protected.

    Welding torches and other parts with a high operating temperature must be allowed to cool down before handling.

    Special provisions apply in areas at risk of fire or explosion
    - observe relevant national and international regulations.

    Welding machines for work in areas with increased electrical risk (e.g. near boilers) must carry the 'Safety' sign. However, the welding machine must not be located in such areas.

    Risk of scalding from escaping coolant. Switch off cooling unit before disconnecting coolant flow or return lines.

    Observe the information on the coolant safety data sheet when handling coolant. The coolant safety data sheet may be obtained from your service centre or downloaded from the manufacturer's website.

    Use only suitable load-carrying equipment supplied by the manufacturer when transporting devices by crane.

    • Hook chains or ropes onto all suspension points provided on the suitable load-carrying equipment.
    • Chains or ropes must be at the smallest angle possible to the vertical.
    • Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).

    If the wirefeeder is attached to a crane holder during welding, always use a suitable, insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).

    Welding with the device during crane transport is only permitted if this is clearly stated in the intended use of the device.

    If the device has a carrying strap or handle, this is intended solely for carrying by hand. The carrying strap is not to be used if transporting with a crane, counterbalanced lift truck or other mechanical hoist.

    All lifting tackle (straps, handles, chains, etc.) used in connection with the device or its components must be tested regularly (e.g. for mechanical damage, corrosion or changes caused by other environmental factors).
    The testing interval and scope of testing must comply with applicable national standards and directives as a minimum.

    Odourless and colourless shielding gas may escape unnoticed if an adapter is used for the shielding gas connection. Prior to assembly, seal the device-side thread of the adapter for the shielding gas connection using suitable Teflon tape.

    1. Safety rules

    Requirement for the shielding gas

    Especially with ring lines, contaminated shielding gas can cause damage to equipment and reduce welding quality.
    Meet the following requirements regarding shielding gas quality:
    • Solid particle size < 40 µm
    • Pressure condensation point < -20 °C
    • Max. oil content < 25 mg/m³

    Use filters if necessary.

    1. Safety rules

    Danger from shielding gas cylinders

    Shielding gas cylinders contain gas under pressure and can explode if damaged. As the shielding gas cylinders are part of the welding equipment, they must be handled with the greatest of care.

    Protect shielding gas cylinders containing compressed gas from excessive heat, mechanical impact, slag, naked flames, sparks and arcs.

    Mount the shielding gas cylinders vertically and secure according to instructions to prevent them falling over.

    Keep the shielding gas cylinders well away from any welding or other electrical circuits.

    Never hang a welding torch on a shielding gas cylinder.

    Never touch a shielding gas cylinder with an electrode.

    Risk of explosion - never attempt to weld a pressurised shielding gas cylinder.

    Only use shielding gas cylinders suitable for the application in hand, along with the correct and appropriate accessories (regulator, hoses and fittings). Only use shielding gas cylinders and accessories that are in good condition.

    Turn your face to one side when opening the valve of a shielding gas cylinder.

    Close the shielding gas cylinder valve if no welding is taking place.

    If the shielding gas cylinder is not connected, leave the valve cap in place on the cylinder.

    The manufacturer's instructions must be observed as well as applicable national and international regulations for shielding gas cylinders and accessories.

    1. Safety rules

    Danger from escaping shielding gas

    Risk of suffocation from the uncontrolled escape of shielding gas

    Shielding gas is colourless and odourless and, in the event of a leak, can displace the oxygen in the ambient air.

    • Ensure an adequate supply of fresh air with a ventilation rate of at least 20 m³/hour.
    • Observe safety and maintenance instructions on the shielding gas cylinder or the main gas supply.
    • Close the shielding gas cylinder valve or main gas supply if no welding is taking place.
    • Check the shielding gas cylinder or main gas supply for uncontrolled gas leakage before every start-up.
    1. Safety rules

    Safety measures at the installation location and during transport

    A device toppling over could easily kill someone. Place the device on a solid, level surface such that it remains stable
    • The maximum permissible tilt angle is 10°.
    Special regulations apply in rooms at risk of fire or explosion
    • Observe relevant national and international regulations.

    Use internal directives and checks to ensure that the workplace environment is always clean and clearly laid out.

    Only set up and operate the device in accordance with the degree of protection shown on the rating plate.

    When setting up the device, ensure there is an all-round clearance of 0.5 m (1 ft. 7.69 in.) to ensure that cooling air can flow in and out freely.

    When transporting the device, observe the relevant national and local guidelines and accident prevention regulations. This applies especially to guidelines regarding the risks arising during transport.

    Do not lift or transport operational devices. Switch off and disconnect devices from the grid before transport or lifting.

    Before transporting the device, allow coolant to drain completely and detach the following components:
    • Wirefeeder
    • Wirespool
    • Shielding gas cylinder

    After transporting the device, the device must be visually inspected for damage before commissioning. Any damage must be repaired by trained service technicians before commissioning the device.

    1. Safety rules

    Safety measures in normal operation

    Only operate the device when all safety devices are fully functional. If the safety devices are not fully functional, there is a risk of
    • injury or death to the operator or a third party
    • damage to the device and other material assets belonging to the operator
    • inefficient operation of the device

    Any safety devices that are not functioning properly must be repaired before switching on the device.

    Never bypass or disable safety devices.

    Before switching on the device, ensure that no one is likely to be endangered.

    Check the device at least once a week for obvious damage and proper functioning of safety devices.

    Always fasten the shielding gas cylinder securely and remove it beforehand if the device is to be transported by crane.

    Only the manufacturer's original coolant is suitable for use with our devices due to its properties (electrical conductibility, anti-freeze agent, material compatibility, flammability, etc.).

    Only use suitable original coolant from the manufacturer.

    Do not mix the manufacturer's original coolant with other coolants.

    Only connect the manufacturer's system components to the cooling circuit.

    The manufacturer accepts no liability for damage resulting from use of other system components or a different coolant. In addition, all warranty claims will be forfeited.

    Cooling Liquid FCL 10/20 does not ignite. The ethanol-based coolant can ignite under certain conditions. Transport the coolant only in its original, sealed containers and keep well away from any sources of ignition.

    Used coolant must be disposed of properly in accordance with the relevant national and international regulations. The coolant safety data sheet may be obtained from your service centre or downloaded from the manufacturer's website.

    Check the coolant level before starting to weld, while the system is still cool.

    1. Safety rules

    Commissioning, maintenance and repair

    It is impossible to guarantee that bought-in parts are designed and manufactured to meet the demands made of them, or that they satisfy safety requirements.

    • Use only original spare and wearing parts (also applies to standard parts).
    • Do not carry out any modifications, alterations, etc. to the device without the manufacturer's consent.
    • Components that are not in perfect condition must be replaced immediately.
    • When ordering, please give the exact designation and part number as shown in the spare parts list, as well as the serial number of your device.

    The housing screws provide the ground conductor connection for earthing the housing parts.
    Only use original housing screws in the correct number and tightened to the specified torque.

    1. Safety rules

    Safety inspection

    The manufacturer recommends that a safety inspection of the device be performed at least once every 12 months.

    The manufacturer recommends that the welding system be calibrated during the same 12-month period.

    A safety inspection should be carried out by a qualified electrician
    • after any changes are made
    • after any additional parts are installed, or after any conversions

    Insulated routing of wire electrode to wire-feed unit

    WARNING!

    Risk of serious injury and property damage or an inferior weld as a result of earth contact or short-circuit of a non-insulated wire electrode.

    In the case of automated applications, ensure that only an insulated wire electrode is routed from the welding wire drum, large wirefeeder spool or wirespool to the wirefeeder (e.g. by using a wirefeeding hose).

    An earth contact or short-circuit can be caused by:

    • an uninsulated, exposed length of wire electrode coming into contact with an electrically conductive object during welding
    • missing insulation between the wire electrode and the earthed enclosure of a robot cell
    • chafed wirefeeding hoses, exposing the wire electrode

    Using wirefeeding hoses ensures that the wire electrode remains insulated as it is transported towards the wirefeeder. To prevent chafing, do not route the wirefeeding hoses over sharp edges. Use hose holders or hose protectors as necessary. Coupling pieces and hoods for welding wire drums also ensure safe transport of the wire electrode.
