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.

• 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.

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.

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.

• 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.

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.

• 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.

• 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.

• Are only designed for use in industrial settings
• Can cause line-bound and radiated interference in other areas

• 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.

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.

• Safety devices
• Network, signal and data transfer lines
• IT and telecommunications devices
• Measuring and calibrating devices

1. Mains supply
   • If electromagnetic interference arises despite the correct mains connection, additional measures are necessary (e.g. use of a suitable line filter)

1. 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

1. Equipotential bonding

1. Earthing of the workpiece
   • If necessary, establish an earth connection using suitable capacitors.

1. Shield, if necessary

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.

• 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 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.

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.

• 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.

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.

Risk of suffocation from the uncontrolled escape of shielding gas

The venting duct is a very important safety device. When choosing the installation location, ensure that the cooling air can enter and exit unhindered through the air ducts on the front and back of the device. Electroconductive metallic dust must not be allowed to get sucked directly into the device (e.g. from grinding work).

The devices are designed for the mains voltage specified on the rating plate. If your version of the appliance does not come with mains cables and plugs ready-fitted, these must be fitted in accordance with national regulations and standards. For details of fuse protection of the mains lead, please see the technical data.

The power source is generator-compatible.

In order to dimension the required generator output, the maximum apparent power S_1max of the power source is required.

The maximum apparent power S_1max of the power source can be calculated as follows:
S_1max = I_1max x U₁

See device rating plate or technical data for I_1max and U₁ values

The generator apparent power S_GEN needed is calculated using the following rule of thumb:
S_GEN = S_1max x 1.35

A smaller generator may be used when not welding at full power.

IMPORTANT! The generator apparent power S_GEN must always be higher than the maximum apparent power S_1max of the power source.

When using single-phase devices with a 3-phase generator, note that the specified generator apparent power is often only available as a whole across all three phases of the generator. If necessary, obtain further information on the single-phase power of the generator from the generator manufacturer.

• Welding: Pull back and hold the torch trigger
• End of welding: Release the torch trigger

2-step mode

• Start of welding with starting current I_S: Pull back and hold the torch trigger
• Welding with main current I₁: Release the torch trigger
• Lowering to final current I_E: Pull back and hold the torch trigger
• End of welding: Release the torch trigger

4-step mode

*) Intermediate lowering

Intermediate lowering during the main current phase reduces the welding current to the specified reduced current I-2 .

• To activate intermediate lowering, push forward and hold the torch trigger
• To revert to the main current, release the torch trigger

Briefly pull back the torch trigger to start intermediate lowering to the specified reduced current I₂. Briefly pull back the torch trigger a second time, to restore the main current I₁.

Special 4-step mode: Variant 1

Variant 1 of the special 4-step mode is activated with the following parameter setting:

• Starting current time = off
• Final current time = off
• Reduced current slope 1 = off
• Reduced current slope 2 = off

• I2 via torch trigger = on
• Reduced current button function = I2

• Push forward and hold the torch trigger: the welding current continuously drops at the set reduced current slope 1 value until it reaches the specified reduced current I₂. It remains at the reduced current value I₂ until the torch trigger is released.
• When the torch trigger is released: the welding current rises at the specified reduced current slope 2 value until it reaches the main current value I₁.

Special 4-step mode: Variant 2

Variant 2 of the special 4-step mode is activated with the following parameter setting:

• Starting current time = off
• Final current time = off
• Reduced current slope 1 = on
• Reduced current slope 2 = on

• I2 via torch trigger = off
• Reduced current button function = I2

In variant 3, push forward and hold the torch trigger to start intermediate lowering of the welding current. Release the torch trigger to resume the main current I₁.

When the torch trigger is pulled back, welding ends immediately without DownSlope and final current.

Special 4-step mode: Variant 3

Variant 3 of the special 4-step mode is activated with the following parameter setting:

• Starting current time = off
• Final current time = 0.01 s
• Reduced current slope 1 = off
• Reduced current slope 2 = off

• I2 via torch trigger = off
• Reduced current button function = I2

• Welding start-up and welding: briefly pull back and release the torch trigger - the welding current will rise at the specified UpSlope value from the starting current I_S until it reaches the main current value I₁.
• Push forward and hold the torch trigger for intermediate lowering
• Release the torch trigger to resume the main current I₁
• End of welding: briefly pull back and release the torch trigger

Special 4-step mode: Variant 4

Variant 4 of the special 4-step mode is activated with the following parameter setting:

• Starting current time = on
• Final current time = on
• Reduced current slope 1 = off
• Reduced current slope 2 = off

• I2 via torch trigger = off
• Reduced current button function = I2

• The longer the torch trigger is held in the forward position during welding, the more the welding current increases (up to the maximum).
• The welding current remains constant when the torch trigger is released.
• The longer the torch trigger is pushed forward again, the more the welding current decreases.

Special 4-step mode: Variant 5

Variant 5 of the special 4-step mode is activated with the following parameter setting:

• Starting current time = off
• Final current time = off
• Reduced current slope 1 = off
• Reduced current slope 2 = off

• I2 via torch trigger = off or on
• Reduced current button function = I1

• Welding start-up with starting current I_S and UpSlope: Pull back and hold the torch trigger
• Intermediate lowering to I₂ and changing from I₂ back to the main current I₁: briefly press (< 0.5 s) and release the torch trigger
• End the welding process: press the torch trigger for longer (> 0.5 s) and release.

The process is automatically ended after the DownSlope phase and the final current phase.

If the torch trigger is pressed briefly (< 0.5 s) and released during either the DownSlope phase or the final current phase, then an UpSlope will take effect until it reaches the main current and the welding process will continue.

Special 4-step mode: Variant 6

Variant 6 of the special 4-step mode is activated with the following parameter setting:

• Starting current time = off
• Final current time = on
• Reduced current slope 1 = off
• Reduced current slope 2 = off

• I2 via torch trigger = on
• Reduced current button function = I2

When the spot welding operating mode is selected, the symbol for spot welding appears on the status indicator next to the welding process symbol:

• Welding: briefly pull back the torch trigger
  The welding time corresponds to the value set for the spot welding time setup parameter.
• To end the welding process prematurely: pull the torch trigger back again

HF ignition is activated when a time value has been set for the ignition timeout setup parameter in the HF menu.
The HF ignition indicator lights up in the status bar on the control panel.

Unlike touchdown ignition, HF ignition eliminates the risk of contamination of the tungsten electrode and the workpiece.

Procedure for HF ignition:

1Place the gas nozzle down on the ignition location, ensuring there is a gap of approx. 2 to 3 mm (5/64 to 1/8 in.) between the tungsten electrode and the workpiece Gap exists.

2Increase the tilt angle of the welding torch and actuate the torch trigger according to the mode you have selected

The arc ignites without the electrode touching down on the workpiece.

3Tilt the welding torch back into the normal position

4Carry out welding

If the ignition timeout setup parameter is set to off, HF ignition is deactivated. The welding arc is ignited by touching the workpiece with the tungsten electrode.

Procedure for igniting the arc using touchdown ignition:

1Place the gas nozzle down on the ignition location, ensuring there is a gap of approx. 2 to 3 mm (5/64 to 1/8 in.) between the tungsten electrode and the workpiece Gap exists

2Actuate the torch trigger

shielding gas flows

3Gradually tilt the welding torch up until the tungsten electrode touches the workpiece

4Raise the welding torch and rotate it into its normal position

The arc ignites.

5Carry out welding

If the tungsten electrode is overloaded, material can detach from the electrode that then contaminates the weld pool.

If the tungsten electrode is overloaded, the "Electrode overload" indicator in the status bar of the control panel lights up.
The "Electrode overload" indicator depends on the electrode diameter and welding current that have been set.

The power source has an ignition timeout function.

Once the torch trigger is pressed, gas pre-flow begins immediately. Ignition then begins. If an arc does not appear within the time specified in the Setup menu, the power source cuts out automatically.

The settings for the parameter Ignition timeout are described in the section "The HF menu" from page (→) onwards.

The settings for the parameter Ignition timeout are described in the section "The HF menu" from page (→) onwards.

The welding current set at the start of welding is not always ideal for the welding process as a whole:

• if the amperage is too low, the base material will not melt sufficiently
• if overheating occurs, the liquid weld pool may drip

The TIG pulsing function (TIG welding with pulsing welding current) offers a remedy:
a low base current (2) rises steeply to the significantly higher pulse current and, depending on the set duty cycle (5), drops back to the base current (2).
In TIG pulsing, small sections of the welding location melt quickly and then solidify again quickly.
In manual applications using TIG pulsing, the welding wire is applied in the maximum current phase (only possible in the low frequency range: 0.25 - 5 Hz). Higher pulse frequencies are mainly used in automatic mode to stabilise the arc.

TIG pulsing is used for out-of-position welding of steel pipes or when welding thin sheets.

Mode of operation of TIG pulsing when TIG DC welding is selected:

The tacking function is available for the TIG DC welding process.

When a time period is specified for the tacking setup parameter (4), the tacking function is assigned to 2-step mode and 4-step mode. The operating sequence of the modes remains unchanged.
The tacking (TAC) indicator lights up in the status bar on the display:

During this period, there is a pulsed welding current that makes the weld pool run together better when two parts are being tacked.

Mode of operation of tacking function for TIG DC welding:

Tacking function - welding current curve

Legend:

• after the end of the starting-current phase (2) 
• with the UpSlope phase (3)

Depending on what tacking period has been set, the pulsed welding current may continue up to and including the final current phase (6) (tacking setup parameter (4) set to "on").

After the tacking time has elapsed, welding continues at a constant welding current, and any pulsing parameters that may have been set continue to be available.

The CycleTIG stitch welding process is available for the TIG DC welding process.
The welding result is influenced and controlled by different parameter combinations.

The main advantages of CycleTIG are easy control of the weld pool, targeted heat input and fewer temper colours.

CycleTIG variations

CycleTIG + low base current

• For out-of-position welding, edge applications and orbital welding
• Well suited to joins on heavy/light-gauge sheets
• Excellent weld characteristics
• HF ignition only at welding start
• Long electrode service life
• Good control of the weld pool
• Targeted heat input

CycleTIG + reversed polarity ignition = on + base current = off

• For repair work (e.g. edge applications)
• Targeted heat input
• Biggest advantage in combination with the HF ignition ignition setting = Touch HF
• HF ignition at every cycle (!)
• Very short electrode service life (!)

Recommendation: iWave AC/DC with the reversed polarity ignition ignition setting = auto

CycleTIG + tacking

• For tacking light-gauge sheets, orbital applications and for joins on heavy and light-gauge sheets
• HF ignition only at welding start
• Long electrode service life
• Good control of the weld pool
• Targeted heat input

CycleTIG + pulse
CycleTIG can be used individually with all pulse settings. This allows pulsing in both the high power and low power phases.

• For tacking light-gauge sheets and for cladding applications
• For joins on heavy/light-gauge sheets
• HF ignition only at welding start
• Long electrode service life
• Good control of the weld pool
• Targeted heat input
• Excellent seam appearance
• Individual pulse settings possible
• More parameters to set

IMPORTANT! Observe the instructions on the packaging of the rod electrode when selecting the appropriate type of current and for correctly connecting the electrode cable and grounding cable.

Setting range: 0 - 100% (of main current)
Factory setting: 20

0 ... soft and low-spatter arc
100 ... harder and more stable arc

Functional principle:
At the instant of droplet transfer or in the event of a short circuit, there is a momentary rise in amperage. In order to obtain a stable arc, the welding current is temporarily increased. If the rod electrode threatens to sink into the weld pool, this measure prevents the weld pool solidifying, as well as preventing more prolonged short circuiting of the arc. This largely prevents the rod electrode from sticking.

Advantages

• Improved ignition properties, even when using electrodes with poor ignition properties
• Better fusion of the base material in the start-up phase, meaning fewer cold-shut defects
• Largely prevents slag inclusions

Example with a starting current > 100% (HotStart)

(1)	Starting current time 0-2 s, factory setting 0.5 s
(2)	Starting current 0-200%, factory setting 150%
(3)	Main current = pre-set welding current I1

Mode of operation
during the specified starting current time (1), the welding current I₁ (3) is increased to the starting current (2).

The starting current time is set in the Setup menu.

A starting current < 100% (SoftStart) is intended for basic electrodes. Ignition takes place at a low welding current. Once the arc is stable, the welding current continues to rise until it reaches the welding current command value.

Example with a starting current < 100% (SoftStart)

Benefits:

• Improved ignition properties for electrodes that ignite at low welding currents
• Largely prevents slag inclusions
• Reduces welding spatter
  

(1)	Starting current
(2)	Starting current time
(3)	Main current

The starting current time is set in the rod electrodes menu.

As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will tend to stick. This may also cause the rod electrode to burn out.

Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode begins to stick, the power source immediately switches the welding current off. After the rod electrode has been detached from the workpiece, the welding process can be continued without any problems.

The anti-stick function can be activated and deactivated in the rod electrodes menu.

Starting current time
The starting current time specifies the duration of the starting-current phase .

Factory setting: off

IMPORTANT! The starting current time only applies to 2-step mode and spot welding. In 4-step mode, the duration of the starting-current phase  is controlled using the torch trigger.

Final current time
The final current time specifies the duration of the final current phase.

off / 0.01 - 30 s
Factory setting: off

IMPORTANT! The final current time only applies to 2-step mode and spot welding. In 4-step mode, the duration of the final current phase is controlled using the torch trigger (see "TIG operating modes").

Slope reduced current
To set the Slope1 reduced current and Slope2 reduced current parameters

Slope1 reduced current

off / 0.01 - 30 s
Factory setting: off

If a time value has been entered for the Slope1 reduced current parameter, the short-term current reduction or current increase is not abrupt, but rather slow and adapted to the desired current curve.
This reduces negative effects on the weld seam and component, especially for aluminium applications.

Slope2 reduced current

off / 0.01 - 30 s
Factory setting: off

If a time value has been entered for the Slope2 reduced current parameter, the adaptation of the reduced current to the welding current is not abrupt, but rather slow and adapted to the desired current curve.

For example, during a current increase, the weld pool is heated slowly, not abruptly. This allows the weld pool to outgas and reduces pores during aluminium welding.

Spot welding time

To set the Slope1 reduced current and Slope2 reduced current parameters

Slope1 reduced current

off / 0.01 - 30 s
Factory setting: off

If a time value has been entered for the Slope1 reduced current parameter, the short-term current reduction or current increase is not abrupt, but rather slow and adapted to the desired current curve.
This reduces negative effects on the weld seam and component, especially for aluminium applications.

Slope2 reduced current

Factory setting: off

If a time value has been entered for the Slope2 reduced current parameter, the adaptation of the reduced current to the welding current is not abrupt, but rather slow and adapted to the desired current curve.

For example, during a current increase, the weld pool is heated slowly, not abruptly. This allows the weld pool to outgas and reduces pores during aluminium welding.

For synchronous welding, the AC frequency must be set to "Syn" on both power sources.
Synchronous welding is used for thick material thicknesses to achieve a high deposition rate and to minimise inclusions during welding.

IMPORTANT! Owing to the phasing of the input voltage, in some cases the synchronisation of the two power sources cannot be carried out properly.
In this case, pull out the mains plug of the power source, turn it through 180° and plug it back in again.

To select characteristics

I-constant / 0.1 - 20.0 A/V / P-constant
Factory setting: I-constant

Adjustable characteristics

(1)	Load line for rod electrode
(2)	Load line for rod electrode where arc length is increased
(3)	Load line for rod electrode where arc length is reduced
(4)	Characteristic for parameter setting I-constant (constant welding current)
(5)	Characteristic for parameter setting 0.1 - 20.0 (drooping characteristic with adjustable slope)
(6)	Characteristic for parameter setting P-constant (constant welding power)

• If the I-constant characteristic is set, the welding current will be kept constant, irrespective of the welding voltage. This results in a vertical characteristic (4).
• The setting is particularly suitable for
  rutile electrodes,
  basic electrodes,
  gouging (set the dynamic to 100 for gouging).

• Setting 0.1 - 20.0 is used to set a drooping characteristic (5). The setting range is from 0.1 A/V (very steep) to 20 A/V (very flat).
• Setting a flat characteristic (5) is only advisable for cellulose electrodes.

• If the P-constant characteristic is set, the welding power is kept constant, irrespective of the welding voltage and welding current. This results in a hyperbolic characteristic (6).
• This setting is particularly suitable for cellulose electrodes.

Settings example: I1 = 250 A, arc-force dynamic = 50

(1)	Load line for rod electrode
(2)	Load line for rod electrode where arc length is increased
(3)	Load line for rod electrode where arc length is reduced
(4)	Characteristic for parameter setting I-constant (constant welding current)
(5)	Characteristic for parameter setting 0.1 - 20.0 (drooping characteristic with adjustable slope)
(6)	Characteristic for parameter setting P-constant (constant welding power)

The characteristics (4), (5) and (6) shown here apply when using a rod electrode whose characteristic corresponds to the load line (1) at a given arc length.

Depending on what welding current (I) has been set, the point of intersection (operating point) of characteristics (4), (5) and (6) will be displaced along the load line (1). The operating point provides information on the actual welding voltage and the actual welding current.

Where the welding current (I₁) is permanently set, the operating point may migrate along the characteristics (4), (5) and (6) depending on the welding voltage at that moment in time.

The welding voltage U is dependent upon the arc length.

If the arc length changes (e.g. in accordance with the load line (2)) the resulting operating point will be the point where the corresponding characteristic (4), (5) or (6) intersects with the load line (2).

For characteristics (5) and (6), if a constant value is set for I₁, the welding current (I) will also become smaller or larger depending on the welding voltage.

Break-voltage
Welding voltage limitation

20 - 90 V
Factory setting: 20 V

The arc length depends on the welding voltage. To end the welding process, it is usually necessary to significantly lift the rod electrode away from the workpiece. With this parameter, the welding voltage can be limited to a value that makes it possible to end the welding operation simply by slightly lifting the rod electrode.

Anti-stick

on / off
Factory setting: on

As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will tend to stick. This may also cause the rod electrode to burn out.

Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode begins to stick, the power source immediately switches the welding current off. After the rod electrode has been detached from the workpiece, the welding process can be continued without any problems.

Welding circuit resistance R [mOhm]

Measuring the welding circuit resistance "r" provides information on the overall resistance of the torch hosepack, welding torch, workpiece and grounding cable.

If an increased welding circuit resistance is detected, e.g. after changing the welding torch, this may mean that the following components are faulty:

• Torch hosepack
• Welding torch
• Grounding (earthing) connection to the workpiece
• Grounding cable

Welding circuit inductivity L [µH]

The way that the hosepack is arranged has a very significant effect on the weld properties.
Particularly with pulsed-arc welding and AC welding, a high welding circuit inductivity may occur, depending on the length of the hosepack and on the way that it is arranged. The result is that the current rise is restricted.

The weld results can be optimised by changing the arrangement of the torch hosepack.
The hosepack must be laid out as shown in the illustration.

Performing R/L alignment

Each Bluetooth user has its own MAC address. This MAC address can be used to assign the devices to specific power sources, preventing mix-ups.

The power source is able to communicate with the following devices:

• Remote control RC Panel Basic /BT
• Pedal remote control RC Pedal TIG /BT
• Welding helmet Vizor Connect /BT

An active Bluetooth connection is indicated in the status bar on the display by an illuminated Bluetooth symbol.

For safety reasons, when using Bluetooth devices of the same type, only one device can be actively connected to the power source.
It is possible to establish multiple active Bluetooth connections when using Bluetooth devices of different types.

New Bluetooth devices must always be configured in the Setup menu.

An existing, active Bluetooth connection cannot be interrupted or influenced by another Bluetooth user.

Bluetooth remote controls have priority over wired remote controls or welding torches with control functions.

If the connection between a wired or Bluetooth remote control and the power source is interrupted during the welding process, the welding process is ended.

User management consists of the following sections:

• General
• Create users and roles
• Edit user / roles, deactivate user administration

User management is advisable if several users work with the same power source.
User management works with different roles and the help of NFC keys.

Users are assigned different roles depending on their level of training or qualifications.

User management is advisable if several users work with the same power source.
User management works with different roles and the help of NFC keys.

Users are assigned different roles depending on their level of training or qualifications.

• creating roles,
• editing and managing user data,
• assigning access rights,
• updating the firmware,
• backing up data, etc.

User management
User management encompasses all users registered on the power source. Users are assigned different roles depending on their level of training or qualifications.

NFC card
An NFC card or an NFC key ring is assigned to a certain user who is registered on the power source.
NFC cards and NFC key rings will both be referred to under the general term NFC key for the purpose of these Operating Instructions.

IMPORTANT! Each user should be assigned their own NFC key.

Roles
Roles are used for managing registered users (= user management). Users' access rights and permitted activities are defined by their roles.

Two roles are predefined in the factory under Defaults / User management:

administrator
with full rights and options

The "administrator" role cannot be deleted, renamed or edited.

The "administrator" role is assigned the pre-defined "admin" user, which cannot be deleted. The "admin" user can assign names, languages, units, web passwords and NFC keys.
As soon as "admin" assigns an NFC key, user management is activated.

locked
Factory-set with access to welding processes, but not to process parameters and defaults

• cannot be deleted or renamed
• cannot be edited to approve different functions according to demand

The "locked" role cannot have any NFC keys assigned to it.

If no NFC key is assigned to the pre-defined "admin" user, every NFC key will work to lock and unlock the power source (no user management, see "Locking and unlocking the power source using the NFC key", page (→)).

Please proceed systematically when creating roles and NFC keys.

Fronius recommends creating one or two administrator keys. Without administrator rights, it may in the worst-case scenario no longer be possible to operate a power source.
