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
EN
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
Danger from
toxic gases and
vapours
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.
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.
7
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).
Danger from flying sparks
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.
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.
Risks from mains
current and welding current
8
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 wirespool, 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 touch the electrode when the power source is switched on.
Double the open circuit voltage of a power source can occur between the welding electrodes of two power sources. 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.
EN
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, appoint a second person to switch off the main switch at
the right moment.
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
- Irreparable 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.
9
Position the device with sufficient insulation against electrically conductive environments,
e.g. Insulation against conductive floor or insulation to conductive racks.
If 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.
EMC Device Classifications
EMC measures In certain cases, even though a device complies with the standard limit values for emis-
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.
sions, 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
- Power, 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 correct mains connection, addi-
tional measures are necessary (e.g. use a suitable line filter).
2. Welding power leads
- must be kept as short as possible
- must run 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. Shielding, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
10
EMF measures Electromagnetic fields may pose as yet unknown risks to health:
- effects on the health of others in the vicinity, e.g. wearers of pacemakers and hearing aids
- wearers of pacemakers must seek advice from their doctor before approaching the
device or any welding that is in progress
- for safety reasons, keep distances between the welding cables and the welder's
head/torso as large as possible
- do not carry welding cables and hosepacks over the shoulders or wind them around
any part of the body
Specific hazards Keep hands, hair, clothing and tools away from moving parts. For example:
- Fans
- Cogs
- Rollers
- Shafts
- Wirespools 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.
EN
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 away from the body (devices with wire-feed
unit) 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.
Power sources for work in areas with increased electric risk (e.g. near boilers) must carry
the "Safety" sign. However, the power source 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 and/or ropes onto all suspension points provided on the load-carrying
equipment.
- Chains and ropes must be at the smallest angle possible to the vertical.
- Remove gas cylinder and wire-feed unit (MIG/MAG and TIG devices).
11
If the wire-feed unit is attached to a crane holder during welding, always use a suitable,
insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).
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 accessories (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.
Requirement for
the shielding gas
Danger from
shielding gas cylinders
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.
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.
12
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.
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.

(3) Wire retract button
For retracting the wire electrode with no accompanying flow of gas or current
The wire electrode can be retracted using one of two methods:
Method 1
Retracting the wire electrode using the preset wire retract speed:
Press and hold "Wire retract" button
- The wire electrode will be retracted 1 mm (0.039 in.) after the wire retract
button is pressed
- After a short pause, the wirefeeder continues to retract the wire electrode. If
the wire retract button remains pressed, the speed will increase every
second at a rate of 10 m/min (393.70 ipm) until the preset wire retract speed
is reached
Method 2
Retracting the wire electrode in 1 mm increments (0.039 in. increments) – always
press the wire retract button for less than one second (tap)
NOTE!
Do not allow long lengths of wire electrode to be retracted, as the wire electrode is
not wound onto the wirespool or the welding wire drum when retracted.
24
NOTE!
If there was a ground earth connection with the contact tip before the wire retract
button was pressed, the wire electrode will be retracted when the button is
pressed until it is short-circuit-free - it retracts by no more 10 mm (0.39 in.) with
each press of the button.
If the wire electrode still needs to be retracted, press the wire retract button again.
(4) Wire threading button
For threading the wire electrode into the torch hosepack with no accompanying
flow of gas or current
Wire threading can be performed using one of two methods:
Method 1
Retracting the wire electrode using the preset feeder inching speed:
Press and hold "Wire threading" button
- The wire electrode will be threaded 1 mm (0.039 in.) after the wire threading
button is pressed
- After a short pause, the wirefeeder continues to thread the wire electrode. If
the wire threading button remains pressed, the speed will increase every
second at a rate of 10 m/min (393.70 ipm) until the preset feeder inching
speed is reached
- If the wire electrode comes into contact with a ground earth connection, the
wirefeeding will be stopped and the wire electrode will be retracted again by
1 mm (0.039 in.)
EN
Method 2
Threading the wire electrode in 1 mm increments (0.039 in. increments) – always
press the wire threading button for less than one second (tap)
If the wire electrode comes into contact with a ground earth connection, the
wirefeeding will be stopped and the wire electrode will be retracted again by
1 mm (0.039 in.).
NOTE!
If there was a ground earth connection with the contact tip before the wire threading button was pressed, the wire electrode will be retracted when the button is
pressed until it is short-circuit-free – it retracts by no more than 10 mm (0.39 in.)
with each press of the button.
If there is still a ground earth connection with the contact tip after 10 mm (0.39 in.) of wire
retraction, pressing the wire threading button again will cause the wire electrode to be
retracted again by a maximum of 10 mm (0.39 in.). The process will be repeated until
there is no longer a ground earth connection with the contact tip.

WARNING!
An electric shock can be fatal.
If the power source is connected to the mains supply while the work described below is
being carried out, there is a high risk of very serious injury and damage. Only carry out
the work described below when:
the power source mains switch is in the "O" position
▶
the power source is unplugged from the mains
▶
General The feed rollers are not installed in the device when it is first delivered.
In order to achieve optimum wire electrode feed, the feed rollers must be suitable for the
diameter and alloy of the wire being welded.
NOTE!
Risk from inadequate feed rollers.
This can result in poor weld properties.
Only use feed rollers that match the wire electrode.
▶
An overview of the feed rollers available and their possible areas of use can be found in
the Spare Parts Lists.

Feeding in the wire electrode
Insulated routing
of wire electrode
to wirefeeder
WARNING!
Risk of serious injury and 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:
- a non-insulated, exposed length of wire electrode coming into contact with a conductive object during the welding process
- missing insulation between the wire electrode and the earthed enclosure of a robot
cell
- chafed wirefeeding hoses, exposing the wire electrode
To avoid earth contact or short-circuit:
- Use wirefeeding hoses for insulated routing of wire electrode to wirefeeder
- To prevent chafing, do not route the wirefeeding hoses over sharp edges
- Use hose holders or hose protectors where necessary
- Coupling pieces and hoods for welding wire drums are recommended to ensure safe
transport of the wire electrode
Safety

CAUTION!
Risk of damage to wirefeeding hose and welding torch from sharp end of wire
electrode.
Deburr the end of the wire electrode well before feeding in.
CAUTION!
Risk of injury from springiness of spooled wire electrode.
When inserting the wire electrode into the wirefeeding hose, hold the end of the wire
electrode firmly to avoid injuries caused by the wire springing back.
