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.


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.



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.


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.



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


EN 1090-certified

As synergetic control and automatic setting control are built in, Lorch's S3 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 series is fully customisable, allowing you to find the machine that matches your welding requirements perfectly.
