from flying sparks, welding fumes hazardous to health, noise exposure, pos-
sible hazard due to grid current or welding current, etc.)
-Provide suitable protective equipment or
-Construct suitable protective walls and curtains.
Danger from tox-
ic gases and va-
pors
The fumes produced during welding contain toxic gases and vapors.
Welding fumes contain substances that cause cancer, as stated in monograph
118 from the International Agency for Research on Cancer.
9
EN-US

Use at-source extraction source and a room extraction system.
If possible, use a welding torch with an integrated extraction device.
Keep your head out of the welding fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
-Do not breathe them in.
-Extract them from the work area using appropriate equipment.
Ensure that there is a sufficient supply of fresh air. Ensure that there is a ventila-
tion flow rate of at least 20 m³ per hour.
Use a welding helmet with air supply if there is insufficient ventilation.
If there is uncertainty as to whether the extraction capacity is sufficient, com-
pare the measured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding
fumes are:
-The metals used for the workpiece
-Electrodes
-Coatings
-Cleaning agents, degreasers, and the like
-The welding process used
Consult the corresponding material safety data sheets and manufacturer's in-
structions for the components listed above.
Recommendations for exposure scenarios, risk management measures and
identifying working conditions can be found on the European Welding Associ-
ation website under Health & Safety (https://european-welding.org).
Keep flammable vapors (such as solvent vapors) out of the arc radiation range.
When no welding is taking place, close the valve of the shielding gas cylinder or
the main gas supply.
Danger from Fly-
ing Sparks
Flying sparks can cause fires and explosions.
Never undertake welding near flammable materials.
Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the
arc or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through
small cracks and openings. Take appropriate measures to ensure that there is no
risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed
tanks, drums, or pipes if these have not been prepared in accordance with cor-
responding national and international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and
the like are/were stored. Residues pose a risk of explosion.
Risks from grid
current and
welding current
An electric shock can be fatal.
Do not touch voltage-carrying parts inside or outside the device.
10

During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the
feed rollers, as well as all pieces of metal that are in contact with the welding
wire, are live.
Always place the wirefeeder on a sufficiently insulated base or use a suitable in-
sulating wirefeeder holder.
Ensure suitable personal protection with dry temporary backing or cover with
sufficient insulation against the ground potential. The temporary backing or cov-
er must completely cover the entire area between the body and the ground po-
tential.
All cables and leads must be secured, undamaged, insulated, and adequately di-
mensioned. Replace loose connections and scorched, damaged, or inadequately
dimensioned cables and leads immediately.
Before every use, check power connections for secure fit by hand.
In the case of power cables with bayonet connectors, turn the power cable by at
least 180° around the longitudinal axis and pretension.
Do not wrap cables or leads around your body or parts of the body.
Concerning the electrode (rod electrode, tungsten electrode, welding wire, etc.)
-Never immerse it in liquids to cool it
-Never touch it when the power source is switched on.
The open circuit voltage of a welding system may double, for example, between
the electrodes of two welding systems. Touching the potentials of both elec-
trodes at the same time may be life-threatening in some cases.
Have the grid and device supply lead regularly inspected by an electrician to en-
sure that the ground conductor is functioning properly.
Protection class I devices require a grid with a ground conductor and a connector
system with ground conductor contact for proper operation.
Operation of the device on a grid without a ground conductor and on a socket
without a ground conductor contact is only permitted if all national regulations
for protective separation are observed.
Otherwise, this is considered gross negligence. The manufacturer accepts no li-
ability for any damage resulting from improper use.
Use suitable equipment to ensure that the workpiece is sufficiently grounded if
necessary.
Switch off unused devices.
When working at elevated heights, wear a safety harness to prevent falls.
Before working on the device, switch off the device and remove the grid plug.
Secure the device to prevent the grid plug from being connected and switched
on again by applying a clearly legible and understandable warning sign.
After opening the device:
-Discharge all electrically charged components
-Ensure that all components are disconnected from the power supply.
If work is needed on voltage-carrying parts, bring in a second person who will
switch off the main switch at the correct time.
11
EN-US

Stray welding
currents
If the following instructions are not observed, stray welding currents may occur,
which pose a risk of the following:
-Fire
-Overheating of parts connected to the workpiece
-Irreparable damage to ground conductors
-Damage to the device and other electrical equipment
Ensure that the workpiece clamp is securely connected to the workpiece.
Secure the workpiece clamp as close to the spot to be welded as possible.
Position the device with sufficient insulation against electrically conductive envir-
onments, e.g., insulation against electrically conductive floors or electrically con-
ductive mounts.
Observe the following when using power distribution boards, twin-head mounts,
etc.: Even the electrode of the welding torch/electrode holder not in use carries
electric potential. Ensure that there is sufficient insulation when the unused
welding torch/electrode holder is stored.
In automated MIG/MAG applications, only guide the wire electrode from the
welding wire drum, large spool, or wirespool to the wirefeeder with insulation.
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 grid.
EMC device classification as per the rating plate or technical data.
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 operating company is obliged to take appropriate ac-
tion to rectify the situation.
Test and assess the immunity of equipment in the vicinity of the device in ac-
cordance with national and international provisions. Examples of interference-
prone equipment that could be affected by the device:
-Safety devices
-Grid power lines, signal lines, and data transfer lines
-IT and telecommunications equipment
-Devices for measuring and calibrating
Supporting measures to avoid EMC problems:
1.Grid power supply
-If electromagnetic interference occurs despite a grid connection that
complies with regulations, take additional measures (e.g., use a suitable
grid filter).
2.Welding power-leads
-Keep them as short as possible
-Route them close together (also to avoid EMF problems)
-Route them far from other lines
12

3.Equipotential bonding
4.Workpiece grounding
-If necessary, establish grounding using suitable capacitors.
5.Shield, if necessary
-Shield other devices in the vicinity
-Shield the entire welding installation
EMF measures Electromagnetic fields may cause health problems that are not yet known:
-Effects on the health of persons close by, e.g., those with pacemakers and
hearing aids
-Persons with pacemakers must seek advice from their doctor before staying
in the immediate vicinity of the device and the welding process
-Keep distances between welding power-leads and the head/torso of the
welder as great as possible for safety reasons
-Do not carry welding power-leads and hosepacks over your shoulder or wrap
them around your body or body parts
Particular haz-
ard areas
Keep hands, hair, loose clothing, and tools away from moving parts, such as:
-Fans
-Gears
-Rollers
-Shafts
-Wirespools and welding wires
Do not reach into rotating gears of the wire drive or into rotating drive parts.
Covers and side panels must only be opened/removed during maintenance and
repair work.
During operation
-Ensure that all covers are closed, and all side parts have been mounted prop-
erly.
-Keep all covers and side parts closed.
The protrusion of welding wire from the welding torch represents a high risk of
injury (cuts to the hand, facial and eye injuries, etc.).
Therefore, always hold the welding torch away from the body (devices with
wirefeeder) and use suitable protective goggles.
Do not touch the workpiece during or after welding – risk of burns.
Slag may fly off cooling workpieces. Therefore, also wear regulation-compliant
protective equipment when reworking workpieces and ensure that other persons
are sufficiently protected.
Leave the welding torch and other parts with a high operating temperature to
cool before working on them.
Special regulations apply in areas at risk of fire or explosion
– follow the appropriate national and international regulations.
Power sources for work in areas with increased electrical hazard (e.g., boilers)
must be labeled with the symbol (Safety). However, the power source may not be
located in such areas.
Risk of scalding due to leaking coolant. Switch off the cooling unit before discon-
necting connections for the coolant supply or return.
13
EN-US

When handling coolant, observe the information on the coolant safety data
sheet. The coolant safety data sheet can be obtained from your service center or
via the manufacturer's website.
Only use suitable load-carrying equipment from the manufacturer to transport
devices by crane.
-Attach chains or ropes to all designated attachments of the suitable load-
carrying equipment.
-Chains or ropes must be the smallest angle possible from vertical.
-Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).
In the event of crane attachment of the wirefeeder during welding, always use a
suitable, insulating wirefeeder hoisting attachment (MIG/MAG and TIG devices).
If the device is equipped with a carrier belt or handle, then this is used exclus-
ively for transport by hand. The carrier belt is not suitable for transport by crane,
counterbalanced lift truck, or other mechanical lifting tools.
All lifting equipment (belts, buckles, chains, etc.), which is used in association
with the device or its components, must be checked regularly (e.g., for mechanic-
al damage, corrosion, or changes due to other environmental influences).
The test interval and scope must at least comply with the respective valid nation-
al standards and guidelines.
There is a risk of colorless, odorless shielding gas escaping without notice if an
adapter is used for the shielding gas connection. Use suitable Teflon tape to seal
the thread of the shielding gas connection adapter on the device side before in-
stallation.
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.
Danger from
Shielding Gas
Cylinders
Shielding gas cylinders contain compressed gas and may explode if damaged.
Shielding gas cylinders are an integral part of the welding equipment, so they
must be handled very carefully.
Protect shielding gas cylinders with compressed gas from excessive heat, mech-
anical impact, slag, open flames, sparks, and arcs.
Mount the shielding gas cylinders vertically and secure them in accordance with
instructions so they cannot fall over.
Keep shielding gas cylinders away from 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 weld on a compressed shielding gas cylinder.
Always use suitable shielding gas cylinders for the application in question and the
correct matching accessories (controller, hoses, and fittings, etc.) Only use
shielding gas cylinders and accessories that are in good condition.
14

If a valve on a shielding gas cylinder is open, turn your face away from the outlet.
When no welding is taking place, close the valve of the shielding gas cylinder.
Leave the cap on the valve of the shielding gas cylinder when the cylinder is not
connected.
Follow the manufacturer's instructions and applicable national and international
provisions for shielding gas cylinders and accessories.
Danger Posed by
