Data on noise emission values
Danger from tox­ic gases and va­pors
The device produces a maximum noise level of <80 dB(A) (ref. 1pW) when idling and in the cooling phase following operation in relation to the maximum permit­ted operating point at standard loading in accordance with EN 60974-1.
A workplace-specific emission value for welding (and cutting) cannot be spe­cified because this value depends on the welding process and the environmental conditions. It is influenced by a wide range of parameters, such as the welding process itself (MIG/MAG, TIG welding), the selected current type (direct cur­rent, alternating current), the power range, the type of weld metal, the resonance properties of the workpiece, the workplace environment, and many other factors.
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.
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 ventila­tion 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, com­pare 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 in­structions for the components listed above.
Recommendations for exposure scenarios, risk management measures and identifying working conditions can be found on the European Welding Associ­ation 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.
13
Danger from Fly­ing 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 cor­responding 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.
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 in­sulating wirefeeder holder.
Ensure suitable personal protection with dry temporary backing or cover with sufficient insulation against the ground potential. The temporary backing or cov­er must completely cover the entire area between the body and the 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. 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.
-
14
The open circuit voltage of a welding system may double, for example, between the electrodes of two welding systems. Touching the potentials of both elec­trodes at the same time may be life-threatening in some cases.
Have the grid and device supply lead regularly inspected by an electrician to en­sure 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 li­ability for any damage resulting from improper use.
Stray welding currents
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.
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
-
EN-US
EMC Device Classifications
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 envir­onments, e.g., insulation against electrically conductive floors or electrically con­ductive 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.
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 low­voltage 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
15
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 ac­tion to rectify the situation.
Test and assess the immunity of equipment in the vicinity of the device in ac­cordance with national and international provisions. Examples of interference­prone 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:
Grid power supply
1. If electromagnetic interference occurs despite a grid connection that
-
complies with regulations, take additional measures (e.g., use a suitable grid filter).
Welding power-leads
2. Keep them as short as possible
-
Route them close together (also to avoid EMF problems)
-
Route them far from other lines
-
Equipotential bonding
3.
Workpiece grounding
4. If necessary, establish grounding using suitable capacitors.
-
Shield, if necessary
5. 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 haz­ard 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.
-
16
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 discon­necting connections for the coolant supply or return.
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).
-
EN-US
Requirement for the shielding gas
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 exclus­ively 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 mechanic­al damage, corrosion, or changes due to other environmental influences). The test interval and scope must at least comply with the respective valid nation­al 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 in­stallation.
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.
17
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, mech­anical 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.
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.
Danger Posed by Shielding Gas Leak
Safety Measures at the Setup Location and During Transport
Follow the manufacturer's instructions and applicable national and international provisions for shielding gas cylinders and accessories.

OPT/i Safety Stop PL d option
IMPORTANT! The OPT/i Safety Stop PL d safety function was developed as Cat-
egory 3 according to EN ISO 13849-1:2008 + AC:2009. A two-channel feed-in of the input signal is required for this. Bridging the two-channel capability (e.g. by means of a short-circuit bracket) is not permitted and results in the loss of the PL d.
Function overview
The OPT/i Safety Stop PL d option ensures a safety stop of the PL d power source with a controlled end of welding in less than a second. Each time the power source is switched on, the Safety Stop PL d safety function performs a self-test.
IMPORTANT! This self-test must be performed at least once a year to check the function of the safety shutdown.
If the voltage drops at least one of two inputs, the Safety Stop PL d stops the current welding operation; the wirefeeder motor and the welding voltage is switched off. The power source outputs an error code. Communication via the robot interface or bus system continues. In order to restart the welding system, the voltage must be applied again. An er­ror must be acknowledged via the torch trigger, display or interface and the start of welding must be executed again.
30
A non-simultaneous shutdown of the two inputs (> 750 ms) is output by the sys­tem as a critical, non-acknowledgeable error. The power source remains permanently switched off. A reset is performed by switching the power source off/on.

TIG welding processes
EN-US
TIG Dynam­icWire
With TIG DynamicWire, the voltage between the workpiece and the welding wire is measured, allowing the wirefeeder to be actively controlled. The wire speed automatically adapts to the amperage, arc length, weld seam pro­file, or to the air gap to be bridged.
TIG DynamicWire works in Synergic operation. Current and wire speed do not have to be set separately. The wire speed can be optimized via the "TIG wire correction" process parameter.
The Welding Package TIG DynamicWire provides characteristics for the most common filler metals.

Danger of electrical current due to electrically conductive dust in the device.
This can result in severe personal injury and damage to property.
General The start-up of the power sources for TIG welding is described on the basis of a
manual, water-cooled TIG application.
WARNING!
Before starting work, switch off all devices and components involved, and disconnect them from the grid. Secure all devices and components involved so they cannot be switched back on. After opening the device, use a suitable measuring instrument to check that electrically charged components (such as capacitors) have been discharged.
WARNING!
Only operate the device if an air filter is fitted. The air filter is a very import­ant safety device for achieving IP 23 protection.

Establishing a ground earth connection to the workpiece
NOTE!
When establishing a ground earth connection, observe the following points:
Use a separate return lead cable for each power source
Keep the torch hosepack and return lead cable as close together as possible
for as long as possible Physically separate the welding circuits of individual power sources
Do not route several return lead cables in parallel;
if parallel routing cannot be avoided, keep a minimum distance of 30 cm between the welding circuits Keep the return lead cables as short as possible and use cables with a large
cross-section Do not cross over return lead cables
Avoid ferromagnetic materials between the return lead cables and the inter-
connecting hosepack Do not reel up long return lead cables - coil effect!
Route long return lead cables in loops
Do not route return lead cables in iron pipes, metal cable trays, or along steel
beams, avoid cable ducts; (routing positive cables and return lead cables together in an iron pipe does not cause any problems) If several return lead cables are being used, separate the grounding points
on the component as far as possible and do not allow crossed current paths between the individual arcs. Use compensated interconnecting hosepacks (interconnecting hosepacks
with integrated return lead cable)

The current temperature of the tungsten electrode, taking into account the
-
previous welding time and break
EN-US
Igniting the arc using high fre­quency (HF ignition)
CAUTION!
Risk of injury due to an electric shock
Although Fronius devices comply with all the relevant standards, high-frequency ignition can transmit a harmless but noticeable electric shock under certain cir­cumstances.
Use prescribed protective clothing, especially gloves!
Only use suitable, completely intact and undamaged TIG hosepacks!
Do not work in damp or wet environments!
Take special care when working on scaffolding, work platforms, in tight, diffi-
cult to access or exposed places, or when welding out-of-position!
HF ignition is activated when the "HF ignition" setup parameter is set to "on" un­der process parameters/ignition parameters. The HF ignition indicator lights up on the status bar.
Unlike contact ignition, there is no risk of contaminating the tungsten electrode and workpiece during HF ignition.
Procedure for HF ignition:
Position the gas nozzle at the igni-
1
tion point so that there is a gap of approximately 2 to 3 mm (5/64 ­1/8 in.) between the tungsten elec­trode and the workpiece. A gap ex­ists.

Igniting the arc using high-fre­quency contact (Touch-HF)
CAUTION!
Risk of injury due to an electric shock
Although Fronius devices comply with all relevant standards, the high-frequency ignition can transmit a harmless but noticeable electric shock under certain cir­cumstances.
Use prescribed protective clothing, especially gloves!
Only use suitable, completely intact and undamaged TIG hosepacks!
Do not work in damp or wet environments!
Take special care when working on scaffolds, work platforms, in forced posi-
tions, in tight, difficult to access or exposed places!
The welding process is initiated by briefly touching the workpiece with the tung­sten electrode. The high-frequency ignition is performed after the set HF ignition delay time has elapsed.

Electrode over­load
If the tungsten electrode is overloaded, this can result in material detachment on the electrode, which can cause contamination to enter the weld pool.
If the tungsten electrode is overloaded, the "Electrode overloaded" indicator lights up on the status bar of the control panel. The "Electrode overloaded" indicator depends on the set electrode diameter and the set welding current.

Ignition timeout
The power source has an ignition timeout function.
function
If the torch trigger is pressed, gas pre-flow begins immediately and the ignition procedure is then initiated. If no arc forms during one of the time periods spe­cified under the ignition parameters, the power source automatically switches off.
The setting of the "Ignition timeout" parameter is described in the Process para­meters/ignition and operating mode settings section starting on page 99.
TIG pulsing The welding current set at the start of welding may not always be ideal for the
entire welding process:
If the amperage is too low, the parent material will not be sufficiently
-
melted, If overheating occurs, there is a danger that the liquid weld pool may drip.
-
The TIG pulsing function is able to help with this (TIG welding with a pulsing welding current): A low base current (2) rises steeply to a significantly higher pulse current and falls again in line with the set duty cycle (5) to the base current (2). During TIG pulsing, small sections of the welding area are quickly melted and then allowed to quickly solidify again. During manual applications, the welding wire is applied in the maximum current phase during TIG pulsing (only possible in the low-frequency range from 0.25 - 5 Hz). Higher pulse frequencies are mostly used in automated applications and mainly serve to stabilize the arc.
TIG pulsing is used to weld steel pipes when welding out-of-position or to weld thin sheet metal.

Tacking function The tacking function is used for the TIG DC welding process.
Whenever a period of time is set for the "Tacking" (4) parameter under process parameters/TIG DC settings, the tacking function is assigned to the 2-step and 4-step modes. The sequence of operating modes remains unchanged. The Tacking (TAC) indicator lights up on the status bar:
During this time, a pulsed welding current is available, which optimizes the mer­ging of the weld pool when tacking two components.

Depending on the set tacking duration, the pulsed welding current can be stopped up to and including the final current phase (6) ("Tacking" (4) TIG DC parameter to "on").
After the tacking time has passed, further welding is carried out at a constant welding current. Set pulse parameters are available if applicable.

Synchronous welding is used for thick materials, to achieve a high deposition rate and to minimize inclusions during welding.
IMPORTANT! Due to the phasing of the input voltage, in some cases the syn­chronization of the two power sources cannot be carried out correctly. In this case, disconnect the mains plug of the power sources, turn 180°, and re­connect to the grid.

General TIG pro­cess parameters Welding start / welding end settings
Starting current time
The starting current time indicates the duration of the starting-current phase.
The setting of the Starting current time parameter also influences versions 1 - 6 of special 4-step mode (see page 72 onwards).
off / 0.01 - 30.0 s Factory setting: off
IMPORTANT! The starting current time is only valid for 2-step mode and spot welding. In 4-step mode, the duration of the starting-current phase is determ­ined by the torch trigger.
Final current time
The final current time indicates the duration of the final current phase.
The setting of the Final current time parameter also influences versions 1 - 6 of special 4-step mode (see page 72 onwards).
off / 0.01 - 30 s Factory setting: off
IMPORTANT! The final current time is only valid for 2-step mode and spot weld­ing. In 4-step mode, the duration of the final current phase is determined by the torch trigger (section "TIG operating modes").
4-mode settings
Lowering current Slope 1
The setting of the Lowering current slope 1 parameter also influences versions 1
- 6 of special 4-step mode (see page 72 onwards).
off / 0.01 - 30 s Factory setting: off
If a time value has been entered for the Lowering current Slope 1 parameter, the brief current reduction or current increase is not abrupt, but slow and adapted. This reduces negative influences on the weld and part, especially with aluminum applications.
Lowering current Slope 2
The setting of the Lowering current slope 2 parameter also influences versions 1
- 6 of special 4-step mode (see page 72 onwards).
98
off / 0.01 - 30 s Factory setting: off
If a time value has been entered for the Lowering current Slope 2 parameter, the adaptation from the lowering current to the welding current is not abrupt, but slow and adapted.
In the case of a current increase, for example, the weld pool is heated slowly and not abruptly. This facilitates outgassing of the weld pool and reduces pores dur­ing aluminum welding.

on High-frequency ignition at the start of welding is activated
off No high-frequency ignition at the start of welding. In this case, welding is started by means of contact ignition.
Touch-HF The welding process is initiated by briefly touching the workpiece with the tung­sten electrode. The high-frequency ignition is performed after the set HF ignition delay time has elapsed.
External Start with an external ignition device, e.g., plasma welding
The HF ignition indicator lights up in the status bar if HF ignition has been set to on.
CAUTION!
Risk of injury due to an electric shock
Although Fronius devices comply with all the relevant standards, high-frequency ignition can transmit a harmless but noticeable electric shock under certain cir­cumstances.
Use prescribed protective clothing, especially gloves!
Only use suitable, completely intact, and undamaged TIG hosepacks!
Do not work in damp or wet environments!
Take special care when working on scaffolding, work platforms, in tight, diffi-
cult to access or exposed places, or when welding out-of-position!

HF ignition delay time
Time after touching the workpiece with the tungsten electrode after which high­frequency ignition takes place.
0.1 - 5.0 s Factory setting: 1.0 s
Reversed polarity ignition
(only with iWave AC/DC power sources)
To ensure an optimum ignition sequence during TIG DC welding, the polarity is reversed briefly at the start of the welding process. Electrons emerge from the workpiece and hit the tungsten electrode. This results in rapid heating of the tungsten electrode - an essential prerequisite for optimum ignition properties.
off/on/auto Factory setting: off
Reversed polarity ignition is recommended for welding light-gauge sheets.

IMPORTANT! Ignition timeout is a safety function and cannot be deactivated. The ignition timeout function is described in the "TIG welding" section.
Arc break filter time
Period of time until the safety cut-out following an arc break
If no current flows during the set period of time following an arc break, the power source automatically switches off. Press any button on the control panel or the torch trigger to restart the welding process.
