S Speed Pulse XT
Configurable high-end pulse performance: Control, quality, and perfection.
Super-efficient. Super-variable. Super-smart.
- The perfect arc for every welding application? It’s possible with the innovative Lorch S-series Speed processes. They speed up welding task completion, improve quality and, first and foremost, low-spatter. The pre-installed synergic lines also facilitate welding work. Configure the S series precisely to your needs to ensure that your system fits perfectly into the production environment and welding task. On top of this, all S-series welding units are complemented by their intuitive operating concept that provides easy access to all setting options. n The Lorch S series is also fully Industry 4.0-capable: It allows the collection, monitoring, and comparison of all relevant welding data when combined with the simple and cost-effective Lorch Connect cloud solution. This maximises transparency, optimising manufacturing costs and increasing productivity.
Best welding properties.
- Cutting-edge processor technology ensures optimum interaction of all parameters and components involved in the welding process. Peak duty cycles and maximum productivity are achieved in the scope of this.
Extra performance by MIG-MAG Speed processes.
- All Lorch Speed processes are available for the S-Series to achieve the most diverse areas of application: The included SpeedPulse XT, TwinPuls XT, SpeedArc XT processes, and the optional SpeedUp, SpeedCold, and SpeedRoot upgrades make welding faster, improve quality, and reduce spatter in any welding job.
Future-proof
