The application focus of our TruPulse lasers is spot and seam welding. Especially for components where heat input, and thus process time, must be low, “cold welding” with TruPulse lasers has a lot of advantages. Materials with high melting points can be welded just as well as materials with high heat conductivity. When cutting metal, TruPulse lasers produce fine contours.

Finely tuned

Several kilowatts of pulse power for a few milliseconds make welding and cutting possible where other methods fail. Whether power, energy or focusability – the TruPulse series includes the entire parameter range for welding and cutting.
Maximum pulse powers of up to 10 kW, pulse durations from 0.2 ms to 50 ms, and maximum pulse energies of up to 120 J make them useful for many purposes – both in manual and automated operation.


Beam generation, beam guidance, power supply, cooling and control are all modular in design. Everything is thought out to the last detail. A laser can serve up to six processing stations. The laser beam is divided or a time offset is used to guide it to the workpiece. In the TruPulse lasers up to 150 W, you can also choose whether your TruPulse laser will be air- or water-cooled.

Best results

The clocked power supply is highly dynamic. It permits an extremely short pulse rise time, and together with the fast real-time power control it permits high pulse-to-pulse stability (deviation < ±0.3% at 10 ms pulse duration). Thus your processing results are consistent at all times.
The pulse frequency of a laser is normally limited by the pulse energy and average power. With the Power Regulated Burst, the average power can also temporarily be exceeded by a factor of several times, reducing the welding time in one processing cycle to a minimum. Long Pulse Welding also opens up new possibilities. With a single laser pulse, you can produce a welding seam by moving the workpiece or the laser beam quickly.


An optional application wizard in the form of a database supports you in determining the optimum welding parameters for your application. If you need to satisfy strict quality requirements in the components you are processing by laser, Quality Data Store helps you record, evaluate and track the relevant laser parameters.
