1. Safety rules

The device generates a maximum sound power level of <80 dB(A) (ref. 1pW) when idling and in the cooling phase following operation at the maximum permissible operating point under maximum rated load conditions according to EN 60974-1.

It is not possible to provide a workplace-related emission value during welding (or cutting) as this is influenced by both the process and the environment. All manner of different welding parameters come into play, including the welding process (MIG/MAG, TIG welding), the type of power selected (DC or AC), the power range, the type of weld metal, the resonance characteristics of the workpiece, the workplace environment, etc.

1. Safety rules

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.

• 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.

• 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.

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.

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.

EMC device classification as per the rating plate or technical data.

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
   • Shield other devices nearby
   • Shield the entire welding installation

1. Safety rules

• Effects on the health of persons in the vicinity, e.g. those with pacemakers and hearing aids
• Individuals with pacemakers must seek advice from their doctor before approaching the device or any welding that is in progress
• For safety reasons, maintain as large a distance as possible between the welding power-leads and the head/torso of the welder
• Do not carry welding power-leads and hosepacks over the shoulders or wind them around any part of the body

1. Safety rules

• Fans
• Cogs
• Rollers
• Shafts
• Wire spools 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.

• 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.

Use only suitable load-carrying equipment supplied by the manufacturer when transporting devices by crane.

• Hook chains or ropes onto all suspension points provided on the suitable load-carrying equipment.
• Chains or ropes must be at the smallest angle possible to the vertical.
• Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).

If the wirefeeder is attached to a crane holder during welding, always use a suitable, insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).

Welding with the device during crane transport is only permitted if this is clearly stated in the intended use of the device.

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 tackle (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.

1. Before commissioning

1. Before commissioning

The welding system is intended exclusively for MMA welding and TIG welding in conjunction with system components from the manufacturer.
Utilisation for any other purpose, or in any other manner, shall be deemed to be not in accordance with the intended purpose.
The manufacturer shall not be held liable for any damages arising from such usage.

• Carefully reading these Operating Instructions
• Following all the instructions and safety rules in these Operating Instructions
• Performing all stipulated inspection and maintenance work

1. Before commissioning

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

Cooling air
The device must be set up in such a way that cooling air can flow freely through the slots in the front and rear panels.

Dust
Ensure that metallic dust is not sucked into the system by the fan, when carrying out grinding for example.

Outdoor operation
The device can be set up and operated outdoors in accordance with IP23 degree of protection. Avoid direct wetting (e.g. from rain).

1. Before commissioning

The welding system is generator-compatible.

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

The maximum apparent power S_1max of the welding system 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 welding system.

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.

1. MMA welding

This function is used to set the starting current.

Setting range: 1 - 200 %

Operating principle:
At the start of the welding process, the welding current is reduced (SoftStart) or increased (HotStart) for 0.5 seconds, depending on the setting.
The change is shown as a percentage from the set welding current.

The duration of the starting current can be changed in the Setup menu using the starting current duration (Hti) parameter.

Setting the starting current:

1Press the setting value button until
	the SoftStart / HotStart indicator lights up
2Turn the adjusting dial until the desired value is reached power source is ready for welding

• Ignis 150 to 160 A
• Ignis 180 to 200 A

Example of HotStart function

Features of SoftStart function:

• Reduced pore formation with certain electrode types

Features of HotStart function:

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

1. MMA welding

To obtain optimum welding results, it will sometimes be necessary to adjust the arc-force dynamic.

Setting range: 0 - 100 (corresponds to 0 - 200 A current increase)

Operating principle:
At the moment of droplet transfer or in the event of a short circuit, the amperage is briefly increased in order to obtain a stable arc.
If the rod electrode is at risk of sinking into the weld pool, this measure prevents the weld pool from solidifying, as well as preventing a prolonged short-circuit of the arc. This largely prevents the rod electrode from sticking.

Setting the arc-force dynamic:

1Press the setting value button until
	the arc-force dynamic indicator lights up
2Turn the adjusting dial until the desired correction value is reached Welding system is ready for welding

• Ignis 150 to 180 A
• Ignis 180 to 220 A

• Arc-force dynamic = 0
  • arc-force dynamic deactivated
  • soft, low-spatter arc
• Arc-force dynamic = 20
  • arc-force dynamic with 40 A current increase
  • harder, more stable arc
• Arc-force dynamic = 60, set welding current = 100 A
  • for the Ignis 150: actual increase is just 80 A as the maximum current limit is reached!
  • for Ignis 180: arc-force dynamic with 120 A current increase

1. MMA welding

Pulse welding is welding with a pulsing welding current. It is used for out-of-position welding of steel pipes or when welding thin sheets.

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

Setting range: 0.2 - 990 Hz

• A low base current I-G rises steeply to the significantly higher pulse current I-P and drops back to the base current I-G after the Duty cycle dcY time. The pulse current I-P can be set on the welding system.
• This results in an average current that is lower than the set pulse current I-P.
• During pulse welding, small sections of the welding location melt quickly and then rapidly re-solidify.

The welding system controls the Duty cycle dcY parameter and base current I-G according to the set pulse current and pulse frequency.

Pulse welding - welding current curve

• F-P: Pulse frequency (1/F-P = time interval between two pulses)
• I-P:  Pulse current
• SoftStart/HotStart

• I-G: Base current
• dcY: Duty cycle

To use pulse welding:

1Press the setting value button until
	the pulse welding indicator lights up
2Turn the adjusting dial until the desired frequency value (Hz) is reached Welding system is ready for welding

	Pull back and hold the torch trigger
	Release the torch trigger forwards
	Push forward and hold the torch trigger
	Release the torch trigger backwards

• GPo: Gas post-flow time
• I-S: Starting-current phase - the temperature is raised gently at low welding current, so that the filler metal can be positioned correctly
• I-E: Final current phase - to prevent crater cracks or cavitations
• I-1: Main current phase (welding-current phase) - uniform thermal input into the base material, whose temperature is raised by the continuous heat
• I-2:  Reduced current phase - intermediate lowering of the welding current in order to prevent any local overheating of the base material

• GPr: Gas pre-flow time
• t_up: UpSlope phase - the welding current is continually increased
  Duration = 0.5 seconds
• t_down: DownSlope phase - the welding current is continually decreased

Pulse welding is welding with a pulsing welding current. It is used for out-of-position welding of steel pipes or when welding thin sheets.

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

Setting range: 0.5 - 100 Hz

• A low base current I-G rises steeply to the significantly higher pulse current I-P and drops back to the base current I-G after the Duty cycle dcY time. The pulse current I-P can be set on the welding system.
• This results in an average current that is lower than the set pulse current I-P.
• During pulse welding, small sections of the welding location melt quickly and then rapidly re-solidify.

The welding system controls the Duty cycle dcY parameter and base current I-G according to the set pulse current and pulse frequency.

Pulse welding - welding current curve

• I-S = starting current
• I-E = final current
• F-P = pulse frequency (1/F-P = time interval between two pulses)
• I-P = pulse current

• t_up = UpSlope
• t_Down = DownSlope
• dcY = duty cycle
• I-G = base current

To use pulse welding:

1Press the setting value button until
	the pulse welding indicator lights up
2Turn the adjusting dial until the desired frequency value (Hz) is reached Welding system is ready for welding

To activate and set the tacking function, see the description Parameters for TIG welding starting on page (→).

• When a time period is specified for the tAC (tacking) setup parameter, the tacking function is assigned to all operating modes
• The basic operating sequence of each of these modes remains unchanged
• During the specified period, welding is done with a pulse current that makes the weld pool run together better when two components are being tacked.

Welding current curve

• tAC = duration of the pulse current for the tacking process
• I-E = final current
• I-S = starting current
• I-1 = main flow

• t_up = UpSlope
• t_Down = DownSlope
• I-P = pulse current
• dcY = duty cycle
• F-P = pulse frequency
• I-G = base current

The welding system controls the pulse frequency F-P, pulse current I-P, duty cycle dcY and base current I-G parameters according to the set main current I-1.

• after the end of the starting-current phase I-S
• with the UpSlope phase t_up

After the tAC time has elapsed, welding continues at a constant welding current, and any pulse parameters that may have been set are available.
