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.

1. Safety rules

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.

1. Safety rules

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 wire spool, 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 be touched when the welding system is switched on.

Double the open circuit voltage of a welding system can occur between the welding electrodes of two welding systems. 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, have a second person switch off the main switch at the right moment.

1. Safety rules

• 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.

1. Safety rules

• 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.

1. Safety rules

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)
2. 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
3. Equipotential bonding
4. Earthing of the workpiece
   • If necessary, establish an earth connection using suitable capacitors.
5. Shield, if necessary

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 facing 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.

Welding machines for work in areas with increased electrical risk (e.g. near boilers) must carry the 'Safety' sign. However, the welding machine 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.

2. Before installation and commissioning

• Protection against penetration by solid foreign bodies with diameters > 12.5 mm (0.49 in.)
• Protection against spraywater at any angle up to 60° to the vertical

The device can be set up and operated outdoors in accordance with degree of protection IP 23.
Avoid direct wetting (e.g. from rain).

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).

2. Before installation and commissioning

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.

1. Installation and commissioning
2. Before installation and commissioning

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.

2. TIG special functions

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.

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.

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

• 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

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.

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.

2. Manual metal arc welding, CEL welding

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.

1. Welding
2. Manual metal arc welding, CEL welding

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

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.

• 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.

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.

• 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

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.

1. Setup settings

HF ignition

on / off / Touch HF / External
Factory setting: on

on
High frequency ignition is activated when welding is started

off
No high-frequency ignition when welding is started.
In this case, welding starts with touchdown ignition.

Touch HF
The welding process is initiated by briefly touching the workpiece with the tungsten electrode. The high frequency ignition occurs after the set HF ignition delay time has elapsed.

External
Start with external ignition aid, e.g. plasma welding

The HF ignition indicator in the status bar on the display lights up as long as HF ignition has been set to On.

HF ignition delay time
Duration until the high frequency ignition takes place after touching the workpiece with the tungsten electrode.

0.1 - 5.0 s
Factory setting: 1.0 s

Reversed polarity ignition
(iWave AC/DC power sources only)

To optimise the ignition sequence in TIG DC welding, the polarity is reversed briefly when welding starts. Electrons emerge from the workpiece and strike the tungsten electrode. This results in rapid heating-up of the tungsten electrode - which in itself is an essential precondition for optimum ignition performance.

off / on
Factory setting: off

IMPORTANT! Reversed polarity ignition is not recommended when welding light-gauge sheets.

Arc break voltage
for setting a voltage value at which the welding process can be terminated by slightly raising the TIG welding torch.
The higher the break voltage, the higher the arc can be drawn.

The arc break voltage value is stored together for 2-step mode, 4-step mode and operation with a pedal remote control.
If the "Torch trigger" parameter is set to "off", the value is stored separately.
