At a glance:


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

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.

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 Speed XT:

You will now achieve even greater welding speeds - whether you choose our optional Lorch Speed upgrades SpeedUp,
SpeedCold, SpeedPulse, SpeedPulse XT, TwinPuls XT, and SpeedRoot or apply our standard processes SpeedArc, SpeedArc
XT or TwinPuls.


Operating equally well with argon-CO₂ mixed gas and 100% CO₂, Lorch's S5 Pulse XT is perfectly equipped for international

EN 1090-certified:

As synergetic control and automatic setting control are built in, Lorch's S5 Pulse 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-series is fully customisable, allowing you to find the machine that matches
your welding requirements perfectly.



All machines of Lorch's S-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 S5 Pulse 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.

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.

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-series system can be operated by remote control. Remote control can be exercised 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.

Case variants:

Welders opting for the Lorch S-series can select from three different case variants (300 mm wire reels). All of them are
optimally tuned to the conditions present at their location of use: the workshop case for standard applications, the
protective tool case with separate wire feeder cover for increased mobility, and the exceptionally compact dockyard wire
feeder for perfect accessibility.


Every S-series system is fully customisable. This also holds true for the selection of the wire feeder systems. When ordering
your machine, you can choose between a compact or wire feeder system and a dual wire feeder variant.


As it comes with PushPull capability built in, the Lorch S5 Pulse 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 S5 Pulse XT reliably protect it against such external
influences as flying sparks or dust.


The S-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.
