S3 mobile SpeedPulse XT configuration at a glance

Ready for Speed XT
You can now finish your welding jobs even faster by taking advantage of Lorch's optional speed upgrades SpeedRoot, SpeedUp and SpeedCold as well as of the standard options SpeedPulse, SpeedPulse XT, SpeedTwinPuls, TwinPuls XT, SpeedArc and SpeedArc XT.

Our Lorch S3 mobile SpeedPulse XT with trolley wheelset will meet all your mobility needs as it allows you to both carry the unit and move it on its wheels.

Dynamic control
Dynamic control allows the welder, for the first time, to variably adjust a pulse welding machine to a wide range of jobs and welding positions as well as to his personal preferences. The welder can use a controller to directly access the arc characteristic and change it from soft to hard.

Ready for Pulse
Highly developed processor technology provides for the seamless interaction of all parameters and components involved in the welding process. The results of this smooth interaction are superior duty cycle levels and maximum productivity.

The 300 to 500 ampere models included in Lorch's S SpeedPulse XT-series are powerful enough to weld materials of all levels of thickness.

Operating equally well with argon-CO₂ mixed gas and 100% CO₂, Lorch's S3 mobile SpeedPulse XT is perfectly equipped for international use.

EN 1090-certified
As synergetic control and automatic setting control are built in, Lorch's S3 mobile SpeedPulse XT is guaranteed to produce welding results that are in conformity with the EN 1090. Combine your machine with Lorch's special offer EN 1090 package, and you are ready to handle any welding task they can throw at you.

Fully customisable
Every welding machine included in Lorch's S SpeedPulse XT-series is fully customisable, allowing you to find the machine that matches your welding requirements perfectly.

SpeedPulse XT
The new Lorch process SpeedPulse XT boasts patented control technology that is combined with variable arc length control and a dynamic control, which allows for a type of pulse welding that produces highly individual results with next to no spatter.

Variable arc length adjustment
Our new variable arc length control allows you to control the pulse arc more intuitively and with greater efficiency. You can now react much more easily to arising conditions, such as changing gap dimensions or arc blow, by changing the distance between torch and workpiece.

Welding over tack welds
Welding over tack welds will succeed every time and without any jerking or annoying changes in frequency. The reduced amount of spatter cuts down the need for costly rework.

All machines of Lorch's S SpeedPulse XT-series with a power output of up to 500 amperes are also available with a compact housing. This space-saving design allows you to stow your unit under the workbench or use it as a storage surface for equipment that you can place on its top.

EN 1090-certified
The EN 1090 WPS package accompanying the Lorch S3 mobile SpeedPulse XT helps you save time and money as it eliminates the need for individual tests of your welding results. The package is comprised of welding instructions that apply to all relevant standard welding processes and have been certified by an approved and independent authority.

Data documentation
Lorch's optional Q-Data recorder allows you to keep a firm eye on the quality standards your client wants you to observe and detect and avoid any errors before they become a problem.

Remote control
Every Lorch S SpeedPulse XT-series system can be operated by remote control – either using the Lorch Powermaster torch or an external operating panel. A remote control can also be incorporated if you want to operate the machine in electrode mode.

As it comes with PushPull capability built in, the Lorch S3 mobile SpeedPulse XT expands your working radius significantly when used in combination with a PushPull torch or a Lorch NanoFeeder.

Job tool
You can use your PC to access the power source to adjust job settings and transfer them to other power sources with no effort at all.
Protection all around
The various protective mechanisms incorporated into the Lorch S3 mobile SpeedPulse XT reliably protect it against such external influences as flying sparks or dust.

The S SpeedPulse XT-series marries performance with efficiency. Slash your energy costs and produce exceptional welding results at the same time.

Quatromatic lets you save three individual parameter settings and select these in 4-step mode using the torch trigger.

Intuitive operation
The easy-to-read operating panel and the clearly structured user interface ensure that you are ready to start welding without having to make any additional preparations.

Using the TipTronic facility, you save your ideal setting for each weld so that you can effortlessly retrieve the settings one at a time using the Up-Down torch when performing recurring welding tasks.

Plug & Weld
LorchNET is the CAN bus employed by Lorch and serves as a digital hub for all Lorch components. You can start using the components right away after connecting your welding data monitor or external operating panels via a LorchNET cable.
