persons nearby during welding, you must
-draw their attention to all the dangers (risk of being dazzled by the arc or
injured by flying sparks, harmful welding fumes, high noise immission
levels, possible hazards from mains or welding current ...)
-provide them with suitable protective equipment and/or
-erect suitable protective partitions or curtains.
Information on
noise emission
values
Hazards from
noxious gases
and vapours
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.
The fumes given off during welding contain gases and vapors that are
harmful to health.
Welding fumes contain substances which may cause birth defects and
cancers.
Keep your head away from discharges of welding fumes and gases.
Do not inhale any fumes or noxious gases that are given off.
Extract all fumes and gases away from the workplace, using suitable
means.
ud_fr_st_sv_00467 022013
Ensure a sufficient supply of fresh air.
Where insufficient ventilation is available, use a respirator mask with an
independent air supply.
If you are not sure whether your fume-extraction system is sufficiently
powerful, compare the measured pollutant emission values with the
permitted threshold limit values.
Close the shielding gas cylinder valve or central gas supply if no welding is
taking place.
IV
Hazards from
noxious gases
and vapours
(continued)
The harmfulness of the welding fumes will depend on e.g. the following
components:
-the metals used in and for the workpiece
-the electrodes
-coatings
-cleaning and degreasing agents and the like
Hazards from
flying sparks
For this reason, pay attention to the relevant Materials Safety Data Sheets
and the information given by the manufacturer regarding the components
listed above.
Keep all flammable vapors (e.g. from solvents) well away from the arc
radiation.
Flying sparks can cause fires and explosions!
Never perform welding anywhere near combustible materials.
Combustible materials must be at least 11 meters (36 ft. 1.07 in.) away from
the arc, or else must be covered over with approved coverings.
Have a suitable, approved fire extinguisher at the ready.
Sparks and hot metal particles may also get into surrounding areas through
small cracks and openings. Take suitable measures here to ensure that
there is no risk of injury or fire.
Do not perform welding in locations that are at risk from fire and/or
explosion, or in enclosed tanks, barrels or pipes, unless these latter have
been prepared for welding in accordance with the relevant national and
international standards.
EN
Hazards from
mains and welding current
Welding must NEVER be performed on containers that have had gases,
fuels, mineral oils etc. stored in them. Even small traces of these
substances left in the containers are a major explosion hazard.
An electric shock is potentially life-threatening, and can be fatal.
Do not touch any live parts, either inside or outside the machine.
In MIG/MAG and TIG welding, the welding wire, the wire spool, the drive
rollers and all metal parts having contact with the welding wire are also live.
Always place the wirefeeder on an adequately insulated floor or base, or
else use a suitable insulating wirefeeder holder.
Ensure sufficient protection for yourself and for other people by means of a
dry base or cover that provides adequate insulation against the ground/
frame potential. The base or cover must completely cover the entire area
between your body and the ground/frame potential.
All cables and other leads must be firmly attached, undamaged, properly
insulated and adequately dimensioned. Immediately replace any loose
connections, scorched, damaged or underdimensioned cables or other
leads.
V
ud_fr_st_sv_00467 022013
Hazards from
mains and welding current
(continued)
Do not loop any cables or other leads around your body or any part of your
body.
Never immerse the welding electrode (rod electrode, tungsten electrode,
welding wire, ...) in liquid in order to cool it, and never touch it when the
power source is ON.
Twice the open-circuit voltage of one single welding machine may occur
between the welding electrodes of two welding machines. Touching the
potentials of both electrodes simultaneously may be fatal.
Have the mains and the machine supply leads checked regularly by a
qualified electrician to ensure that the PE (protective earth) conductor is
functioning correctly.
Only run the machine on a mains network with a PE conductor, and plugged
into a power outlet socket with a protective-conductor contact.
If the machine is run on a mains network without a PE conductor and
plugged into a power outlet socket without a protective-conductor contact,
this counts as gross negligence and the manufacturer shall not be liable for
any resulting damage.
Wherever necessary, use suitable measures to ensure that the workpiece is
sufficiently grounded (earthed).
Stray welding
currents
Switch off any appliances that are not in use.
Wear a safety harness if working at height.
Before doing any work on the machine, switch it off and unplug it from the
mains.
Put up a clearly legible and easy-to-understand warning sign to stop
anybody inadvertently plugging the machine back into the mains and
switching it back on again.
After opening up the machine:
-discharge any components that may be storing an electrical charge
-ensure that all machine components are electrically dead.
If work needs to be performed on any live parts, there must be a second
person on hand to immediately switch off the machine at the main switch in
an emergency.
If the following instructions are ignored, stray welding currents may occur.
These can cause:
-fires
-overheating of components that are connected to the workpiece
-destruction of PE conductors
-damage to the machine and other electrical equipment
ud_fr_st_sv_00467 022013
Ensure that the workpiece clamp is tightly connected to the workpiece.
Attach the workpiece clamp as close as possible to the area to be welded.
On electrically conductive floors, the machine must be set up in such a way
that it is sufficiently insulated from the floor.
VI
Stray welding
currents
(continued)
When using current supply distributors, twin head wire feeder fixtures etc.,
please note the following: The electrode on the unused welding torch/
welding tongs is also current carrying. Please ensure that there is sufficient
insulating storage for the unused welding torch/tongs.
In the case of automated MIG/MAG applications, ensure that only insulated
filler wire is routed from the welding wire drum, large wirefeeder spool or
wirespool to the wirefeeder.
EN
EMC device
classifications
Devices with emission class A:
-are only designed for use in an industrial setting
-can cause conducted and emitted interference in other areas.
Devices with emission class B:
-satisfy the emissions criteria for residential and industrial areas. This
also applies to residential areas in which power is supplied from the
public low-voltage grid.
EMC device classification as per the rating plate or technical specifications
EMC measuresIn 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.
Examine and evaluate any possible electromagnetic problems that may
occur on equipment in the vicinity, and the degree of immunity of this
equipment, in accordance with national and international regulations:
-safety features
-mains, signal and data-transmission leads
-IT and telecoms equipment
-measurement and calibration devices
Ancillary measures for preventing EMC problems:
a) Mains supply
-If electromagnetic interference still occurs, despite the fact that the
mains connection is in accordance with the regulations, take additional
measures (e.g. use a suitable mains filter).
b) Welding cables
-Keep these as short as possible
-Arrange them so that they run close together (to prevent EMI problems
as well)
-Lay them well away from other leads.
c) Equipotential bonding
d) Workpiece grounding (earthing)
-where necessary, run the connection to ground (earth) via suitable
capacitors.
e) Shielding, where necessary
-Shield other equipment in the vicinity
-Shield the entire welding installation.
VII
ud_fr_st_sv_00467 022013
EMI Precautions
Electromagnetic fields may cause as yet unknown damage to health.
-Effects on the health of persons in the vicinity, e.g. users of heart pacemakers and hearing aids
-Users of heart pacemakers must take medical advice before going
anywhere near welding equipment or welding workplaces
-Keep as much space as possible between welding cables and head/
body of welder for safety reasons
-Do not carrywelding cables and hose pack over shoulder and do not
loop around body or or any part of body
Particular danger
spots
Keep your hands, hair, clothing and tools well away from all moving parts,
e.g.:
-fans
-toothed wheels, rollers, shafts
-wire-spools and welding wires
Do not put your fingers anywhere near the rotating toothed wheels of the
wirefeed drive.
Covers and sideguards may only be opened or removed for as long as is
absolutely necessary to carry out maintenance and repair work.
While the machine is in use:
-ensure that all the covers are closed and that all the sideguards are
properly mounted ...
-... and that all covers and sideguards are kept closed.
When the welding wire emerges from the torch, there is a high risk of injury
(the wire may pierce the welder’s hand, injure his face and eyes ...).
For this reason, when feeder-inching etc., always hold the torch so that it is
pointing away from your body (machines with wirefeeder) and wear suitable
protective goggles.
Do not touch the workpiece during and after welding - risk of injury from
burning!
Slag may suddenly “jump” off workpieces as they cool. For this reason,
continue to wear the regulation protective gear, and to ensure that other
persons are suitably protected, when doing post-weld finishing on
workpieces.
Allow welding torches - and other items of equipment that are used at high
operating temperatures - to cool down before doing any work on them.
Special regulations apply to rooms at risk from fire and/or explosion.
Observe all relevant national and international regulations.
Power sources for use in spaces with increased electrical danger (e.g.
boilers) must be identified by the (for “safety”) mark.
However, the power source should not be in such rooms.
ud_fr_st_sv_00467 022013
VIII
Particular danger
spots
(continued)
Risk of scalding from accidental discharge of hot coolant. Before unplugging
the connectors for coolant forward flow and return flow, switch off the cooling unit.
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.
When hoisting the machines by crane, only use suitable manufacturersupplied lifting devices.
-Attach the chains and/or ropes to all the hoisting points provided on the
suitable lifting device.
-The chains and/or ropes must be at an angle which is as close to the
vertical as possible.
-Remove the gas cylinder and the wirefeed unit (from MIG/MAG and TIG
units).
When hoisting the wirefeed unit by crane during welding, always use a
suitable, insulating suspension arrangement (MIG/MAG and TIG units).
If a machine is fitted with a carrying strap or carrying handle, remember that
this strap is ONLY to be used for lifting and carrying the machine by hand.
The carrying strap is NOT suitable for transporting the machine by crane,
fork-lift truck or by any other mechanical hoisting device.
EN
Factors affecting
welding results

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.
Danger of colourless and odourless inert gas escaping unnoticed, when
using an adapter for the inert gas protection. Seal the adapter thread for the
inert gas connection using Teflon tape before assembly.
The following requirements with regard to shielding gas quality must be met
if the welding system is to operate in a correct and safe manner:
-Size of solid matter particles <40µm
-Pressure dew point <-20°C
-Max. oil content <25mg/m³
Filters must be used if necessary.
NOTE! There is an increased risk of soiling if ring mains are being
used
IX
ud_fr_st_sv_00467 022013
Danger from
shielding-gas
cylinders
Shielding-gas cylinders contain pressurized gas and may explode if they are
damaged. As shielding-gas cylinders are an integral part of the overall
welding outfit, they also have to be treated with great care.
Protect shielding-gas cylinders containing compressed gas from excessive
heat, mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding-gas cylinders in the vertical and fasten them in such a
way that they cannot fall over (i.e. as shown in the instruction manual).
Keep shielding-gas cylinders well away from welding circuits (and, indeed,
from any other electrical circuits).
Never hang a welding torch on a shielding-gas cylinder.
Never touch a shielding-gas cylinder with a welding electrode.
Explosion hazard - never perform welding on a pressurized shielding-gas
cylinder.
Use only shielding-gas cylinders that are suitable for the application in
question, together with matching, suitable accessories (pressure regulators,
hoses and fittings, ...). Only use shielding-gas cylinders and accessories
that are in good condition.
Safety precautions at the installation site and
when being
transported
When opening the valve of a shielding-gas cylinder, always turn your face
away from the outlet nozzle.
Close the shielding-gas cylinder valve when no welding is being carried out.
When the shielding-gas cylinder is not connected up, leave the cap in place
on the shielding-gas cylinder valve.
Observe the manufacturer’s instructions and all relevant national and
international rules applying to shielding-gas cylinders and accessories.
A machine that topples over can easily kill someone! For this reason, always
place the machine on an even, firm floor in such a way that it stands firmly.
-An angle of inclination of up to 10° is permissible.
Special regulations apply to rooms at risk from fire and/or explosion.
Observe all relevant national and international regulations.
