MagicWave 2500 / 3000 TransTig 2500 / 3000TIG & MMA weldingGENERAL REMARKSQuiet, tough, stableTIG welders can raise a heartfelt cheer! Specially for them, Fronius has developed a series of machinesthat make their every wish come true: MagicWave 2500/3000 for DC and AC, and TransTig 2500/3000for DC. Active Wave and digitisation are the key technologies underlying this machine concept.These power sources are up-to-the-minute characters that are a pleasure to work with, in every way: Ever-so discreet, with a super-quiet yet highly stable arc. Extremely straightforward to use - in fact, almostself-explanatory. Tough, powerful and totally digitised. What is more, every single one of them is a member of a complete, totally co-ordinated welding system, all of whose components perfectly complement one another. All in all, the upshot is the sort of welding results which up to now you could only dream of.UTILISATIONFlexible and versatileOne of the many things that make the new MagicWave and TransTig machines such a pleasure to work withis the fact that they are designed for both field and production use. They can cope with the toughest conditions imaginable, putting out up to 250/300 A of power.In terms of materials, these welding systems are very suitable for aluminium and its alloys, but also forlow and high-alloy steels and non-ferrous metals, of course. Thanks to their great versatility, the MagicWave 2500/3000 and TransTig 2500/3000 are used right across the entire spectrum of industry – from the construction of chemical plant, tanks and containersto mechanical and plant engineering, pipeline construction, automotive and railway engineering and aerospace, and taking in all site-erection, maintenance and repair firms. Delivering just as perfect results when used for robot welding as in manual welding.Welding made easyECONOMYA pleasing side-effectThis series of TIG machines is a fine example of just how efficient modern welding systems can be. Their efficiency begins with the high-grade componentrythat is used for all Fronius machines. Special mention should also be made of their high degree of power efficiency, extremely low open-circuit power, automatic cooling-unit cut-out (which has a direct and measurable impact on the current consumption), and of course the automatic cap-shaping function, which reduces the working times needed by the welder. All in all, these features result in outstandingly long operational life,a small number of wearing parts, and lower labour costs. And thus in a welding system that is highly cost-effective in every way.TIG robot welding system with integral cold-wire-feeder unit.WELDING PROPERTIESSimply perfectThe ignition plays a vital rôle in TIG welding. On each of the machines, ignition is possible either with or without touchdown. In non-contact ignition, the arc starts immediately with a high-voltage impulse, ensuring perfect ignition right from the first push of the button – even when you’re using extra-long hosepacks. Touchdown ignition is especially valuable in sensitive areas of application. And the important thing here is to make sure that there are no tungsten inclusions. The digital process control takes good care of this, perfectly controlling the entire sequence.Active Wave ensures peace and quietActive Wave makes TIG AC welding a much quieter business: The integrated digital signal processor always computes – in real time – the waveform that will permit the highest possible arc stability with the lowest possible noise-emission levels. Measurement of these noise levels clearly shows that with Active Wave, even when the machine is delivering 300 A of power, the dbA value is still below 80 dbA.TAC: Spot-by-spot tack weldingBefore you can weld, you have to tack. With TAC, one spot is all it takes – because the pulsed arc sets the two weld-pools in motion, making them “jump together”, in next to no time, to make one single weld-pool. This works fast, and is a lot easier than the old method. The TAC function is also very useful when light-gauge sheets are being welded without filler metal, as here too, the pulsed arc helps the weld-pools to merge more thoroughly.Real skill becomes apparent at the endAt the end of the weld, there are two main things to watch out for: The first of these is the end crater. This has to be filled, at a lower amperage. The power sources take care of this, with the end-crater and downslope functions. The second thing is the gas post-flow, to make sure that the electrode and the weld-pool do not oxidise. In the past, the gas post-flow had to be set manually. On the digital machines, the ideal post-flow time is computed automatically.The way welding ought to be60 120 180 240 300 ANoise volume from conventional inverters Reduced noise volume from Active WaveFor sensitive areas of application: Touchdown ignitiondbA 90807060Simultaneous welding on both sidesWhen joining plates, you normally have to weld a root pass first. This then has to be ground and back-welded –a time-consuming procedure which you can speed up by welding from both sides simultaneously. In “both-sides-simultaneously” TIG-AC welding, both arcs have to be synchronised. This is taken care of by the digital MagicWave power sources.Aluminium is differentAluminium always needs special treatment. So Fronius have made sure that it gets it. For example, in TIG AC welding, aluminium is normally not welded with a pointed electrode tip, but with a shaped cap at the tip of the electrode. On fillet welds, this leads to inadequate root fusion. The MagicWave machines use a pointed electrode with a much smaller shaped cap. This results in perfect root fusion.The cap is shaped automatically, by the way, which means huge time-savings. All you need to do is clamp the pointed electrode into the electrode holder and pre-select the cap diameter, and the arc then immediately forms the shape and size of cap that you want. Another interesting function enables you to make variable adjustments to the AC waveform, giving the welder reliable weld-pool control even at high amperages.SAFETYGreen lights all roundAs anybody at all familiar with Fronius machines will know, their safety features are second to none. This, in itself, is a minimum requirement that every appliance has to fulfil. Every power source comes with the CE mark and with the S mark – permitting welding in confined spaces in conditions of enhanced electrical hazard, also when AC welding, of course. What is more, each of the power sources amply fulfils the requirements of IEC “Degree of protection IP 23”, meaning that it is safely protected from dirt and water, for use in the field. The integral fan is thermostat-controlled and so only runs when it is needed. This reduces dirt collection and prolongs the service life of the power source. At Fronius, though, safety starts even sooner: in the development stage. The MagicWave and TransTig machines were designed from the ground up to be so robust and compact that they can take just about anything in their stride.Cap diameter: 3.2 mm Base metal: AIMg3Sheet thickness: 5 mm Welding amperage: 185 A Welding voltage: 15.6 V AC balance: 0Cap diameter: 1 mm Base metal: AIMg3Sheet thickness: 5 mm Welding amperage: 185 A Welding voltage: 15.6 VAC balance: -5HANDLINGSmall on size, big on quality – the ideal welding torch for this power classOf all the components of the welding system that execute a work function, the welding torch is the most important. You can have the world’s most advanced power source and its very best welder – but if the hosepack is under constant strain, it will still spoil the welding result. Fronius is well aware of this, too. Which is why it is continually developing and improving its welding torches – for instance by adding the water-cooled TIG-welding torch TTW 2500, for the power class up to 250 A.Its ergonomically designed handle-shell is smaller and so fits even better in the welder’s hand - in fact, it can even be held like a pencil. The up/down rockers are easy to actuate while wearing gloves. The handle-shell also integrates a perfect anti-kink feature: The hosepack flexes more quickly, resulting in more precise torch guidance. Importantly for uninterrupted water cooling, the hosepack itself cannot be endlesslyAnything elsewe can do for you?The water-cooled TIG welding torch TTW 2500, with integral up/down rockers.Thanks to its ergonomically shaped handle-shell, the welding torch fits superbly well in the welder’s hand. The perfectly integrated anti-kink device enables the torch to be guided with great precision, even when the hosepack is bent.rotated. A final, economic, argument is that the wearing parts from other Fronius welding torches are all compatible with the TTW 2500.For the power class up to 300 A, other Fronius welding torches can be used as well, of course. Mention should also be made of the TIG welding torch with its integral cold-wire feeder unit for manual and automated cold-wire applications.Perfect interplayFronius is a system supplier. Each member of the system is designed to “fit in” optimally with all the others, in perfect harmony. The system takes in everything from the power source to remote-control units, cooling units, trolleys and a wide range of different robot interfaces, as well as complete welding-data documentation and visualisation.Digital weld-process regulation and controlEnergy-saving inverter technologyGenerator-compatibleThermostat-controlled fan / overtemperature protectionEarth leakage monitoringContinuous welding-current adjustment from torchRemote-controllableSwitchover facility between touchdown and HF ignitionAutomatic gas post-flow (dep. on welding current)Gas-test functionAutomatic cooling-unit cut-outAnti-stick functionFreely selectable parameters on the welding torchJob modeAutomatic cap-shaping functionPolarity reversalRPI ignitionKeylock switchRobot interface, analogue / digitalCold-wire controlOperating modes2-step mode / 4-step modeTAC (programmed tack-welding)AC / DCSpecial 4-step modeTIG pulsed-arcSpot weldingDigital indication ofPlain-text displayRun-statusOperating modeParametersWelding voltage, welding amperage (actual value)Service codesJob numberAdjustable parametersWelding amperageElectrode diameterGas pre-flow time / gas post-flow timeCrater-fill current / start-arcUpslope / downslopeHot-Start / arc-force dynamicAC balance / AC frequency / AC waveformAll plain to seeThe machines in this series are available in threedifferent versions – Standard, Job and Comfort, eachwith differing functions. “Job”, for instance, lets youwork in job mode and allows cold-wire control andautomated applications.The “Comfort” model also includes a number of extraplus-points, such as the plain-text display. This isunique, in terms of both handling guidance and user-friendliness, and ranks at the very forefront of moderntechnology. It functions extremely simply and “tells itlike it is”, in plain text. That means no abbreviations,no numerical codes, just straight-to-the-pointannouncements like “Main current”, “Lowered current”or “Electrode diameter”. The additional parameters canbe set very conveniently using a navigation menu. Theplain-text display is easy to read and absolutely self-explanatory, meaning that anyone can learn to use itstraight away.

If required, use a speaker stand∙If required, use sound absorbing materials around the room∙Place the speaker facing towards the listener to minimize the distance and reflections from the walls and get the best stereo image5.2 Setting up Mid/Near-Field InstallationMid-field or near-field installation is usually directed towards a specific listener orlisteners in a specific location of the room. To maximize your listening experience:1. Make sure that the speakers are set at head height (whether you will be usingthe speakers sitting down or standing up).Figure 2: setting the Dolev 8 at head height6 Dolev 8 - Installing the Speaker2. Position the speaker at an angle so that together with the listener, anequilateral triangle is created.3. Try to keep the speakers at a distance of about 50cm from the walls4. Try to keep a distance of about 1.5 to 2 meters between the speakers.Figure 3: Dolev 8 Optimum positioningiNote that even though the illustration in Figure 3 shows twospeakers each Dolev 8 package includes one speaker.5.3 Setting up Far-Field InstallationFar-field positioning is suitable for a large amount of listeners (unlike the near-fieldpositioning where the speakers are directed at a specific listener). To maximize thelistening experience:1. Make sure that the speakers are facing the center of the room.2. Make sure that both speakers are placed along the same wall in the room(not facing each other).3. Aim to achieve the largest sweet spot.For optimum results we recommend that you either experiment and locate thesweet spot by trial-and-error or alternatively, consult an acoustic engineer.Dolev 8 - Installing the Speaker 75.4 Installing the SpeakerTo install the speaker, do the following:1.
