Welding is now clearly faster,giving you more productivity.

The Speedadvantage

Because Speed

= Productivity

Ever since mankind exists, people are striving for improvements.For this reason, we at Lorch have been searching for genuine speed for years.

Believe us: speed is not just speed. Speeding up the welding process is only possible,if penetration and weld integrity is assured and the whole process is extremely simple touse for everyone. The best quality is what counts. Only when this is the case, can you step

ahead and enter the next level of productivity: lean-welding processeswithout time-consuming preparation work and lots of post weld reworking tasks.

Thousands of hours of hard work are worth it:Lorch made welding fast.

3 MIG-MAG process innovations help to sustain reduction of your manufacturing costs.They clearly increase your welding speeds, simplify the process considerably and enable

productivity, which has not been possible until now.

Two Lorch welding units offer you this speed and their quality is included among the bestin the world. Inside they carry the speed processes, for speeding up your manufacturing.

We call them the Masters of Speed. Units, about which welders saywith a low voice filled with pride: I am welding with a Lorch.

The Speed advantage – Process innovation 1:

And speed becomes producAdded value with eachmeter

Deeper penetration - harder, and less noisy.Only if the root is captured perfectly, will the weld seam besound and long lasting. The SpeedPulse of the S proves itsability with high quality weld seam appearance and excellentfusion characteristics, which is also ideal for aluminium.SpeedPulse is much quieter. Up to 10 dB(a) infact. Thereforereducing the strain on your ears by half and optimising yourconcentration for producing a really great welding seam.

SpeedPulse.Up to 48 % faster.The key to higher speed is toincrease the filler wire burn offperformance. Until now, one pulse

has always been one droplet. However, ourprocess specialists found ways of enlarging this drop, thus permitting a controlled, almost

constant metal flow into the weldpool. The leading droplet, which is pulsed, is always then followed bya second, controlled metal transition in spray arc form. This “gain” of material clearly shows its effect:more speed. Immediately faster when used for manual welding and outstanding in automation.30 % faster with stainless steel and up to 48 % with steel. Always giving best quality traditionallyassociated with pulse and remarkably easier to use for the operator.

SpeedPulse. Ideal especially for steel. As time is money.You weld in order to earn money and … to comply with terms. So why do you not pulse weld withsteel? Even with steel, SpeedPulse is clearly better and simpler to master. You also pulse with stainlesssteel and aluminium. Yes, you’ll agree – this is right, but with steel, pulsing is slower than MIG-MAG.That is no longer true! This is in the past. SpeedPulse is one of the best processes in the high-speedrange. More power, more speed advantage. You must try it. With total pulse quality. SpeedPulse alsofor steel. SpeedPulse for your manufacturing.

SpeedPulse. Easier welding and less reworking.The stability of the arc proves: SpeedPulse makes the handling of the weldpool easier. A pointed wire end,

allowing the arc energy to be focused directly into theseam throughout the entire current range. As is the casewith standard MIG-MAG welding filler wire spools no lon-ger need to be changed depending on material thicknessto be welded. For example you can weld 1.0 mm metalsheets with 1.2 mm filler wire and weld smoothly andwithout interruption – up to the maximum current range.SpeedPulse also makes the complete process colder. This

is highly visible by the temper colours when welding stainless steel. It is possible to weld the requiredseam faster and with less distortion. For each day this means that many more meters of weld can beachieved. Without loss of time due to changing of wires and post weld re-work – You’ve got the SpeedPulse.

For maximum MIG-MAG performance:Up to 30 % faster.The SpeedArc is considerably more focused.It has a much higher energy density thus reachinggreater arc pressure into to the weld pool.The result is impressive as it makesMIG-MAG welding up to 30 % faster.

Even 15 mm in just onelayer become possible.The SpeedArc is MIG-MAG-Max. But not onlyits speed makes it more productive.There is also the fact that components whichhad to be welded in several passes before,can now - due to the Lorch SpeedArc - be joinedin one single pass, up to 15 mm thick.This is productivity that pays off; this is valueadded welding. How the whole process works isand remains a secret of our engineers here inAuenwald, but you can be sure that it can save youa lot of money and help to get a lot of yourdelivery dates under control.

Vertical-up welders becomeVertical-up welding as easy

Vertical-up welding?Was difficult in the past.The perfect vertical-up welding seam was an“award“. The necessary triangle or Christmas treemovement of the hand was a technique only ma-stered by experts. The material must not be toocold; the root must be good and achieved withcare. With a certain reverence, these men werecalled Christmas tree welders, because there wasno other possibility to weld vertically upwards.However, this technique was almost as slow as atree itself grows, and deadline pressure often wasan own goal. So it was logical that some of ourengineers searched for a simplification.They have found it. The honor is now ours.

SpeedUp - the „simple” oneVertical welding is re-invented.The trick is the combination of two processes orbetter two arcing phases. The first one: The “hot”phase with high-energy insertion is for optimummelting of the material. Due to the perfect arcregulation you proceed from this phase withoutany transition and therefore virtually spatter-freeinto the other one: The “cold” phase, with reducedenergy insertion for an exactly dimensioned weldseam. This phase also ensures good penetrationand exact “a”-measurement dimensions.It sounds simple and it really is. Because evensemi-skilled welders master the SpeedUp processin a very short time. With excellent root penetration,they also now weld vertically upin an easy and skilful manner.

SpeedUp speeds up.If you hammer a large hole in a wall just in order to laya thin cable, you need a lot of time to plaster it up again.This was also the case for vertical welding. Until now!SpeedUp by Lorch works in a much more precise way:Like a small, exact hole in the wall which is then re-pla-stered fast as the wind, the “a”-measurement is appliedas exactly as possible on metal sheets of up to 12 mm.The concentrated SpeedUparc is practically twice asfast with steel and stainlesssteel and is made possibleby the precision and thehigh-end control techniqueof the Lorch units. ForLorch P synergic, SpeedUpis approx. 60 – 80 % faster,an enormous progress foreveryone welding every avertical seam. And for those using a Lorch S-SpeedPulseare up to 100 % faster. SpeedUp with PulseControl.

MIG-MAG vertical welding also withaluminium? And round the corner?You think that this is not possible with a conventionalMIG-MAG unit? You’re right. But the Lorch P synergicis MIG-MAG-Max, it really works with it. The weldseam is almost as perfect – as it is with TIG – also withsteel and stainless steel. In addition, the PowerMasterremote control torch and the Tiptronic memory for yourwelding jobs. Just a keypress from horizontal weld tothe vertical position and back again. No more time-con-suming running between the unit and the workpiece.This is productivity. SpeedUp your work.
