Sophisticated power pack

The tried-and-tested pulsed solid-state lasers in the TruPulse series enable short, high-energy pulses at high power. The pulse power of several kilowatts for a few milliseconds means that spot welding and seam welding are now also possible in places where other methods fail. Thermally sensitive applications in particular benefit from the advantages of pulsed solid-state lasers. With their modular layout, the lasers can be adapted to your individual manufacturing task. The TruPulse series has been technically optimized over decades, making the system highly reliable.


Individually adaptable lasers due to the broad product portfolio and the modular layout of the TruPulse

100% consistent power output

With our real time laser power control, the exact power you select is the power at the workpiece.

Accurate pulse-to-pulse stability

The laser compares the pulse shape you have chosen with the actual pulse shape in a 10 μs cycle.

Improved average power

With the burst function you can temporarily increase the average power several times over.

Integrated know-how

The WeldAssist option provides suggested values for all of the process parameters depending on the material and welding depth.

TruPulse integrated beam guidance

Due to its integrated beam guidance, the TruPulse can be perfectly adapted to your application. With up to six pluggable laser outlets and a flexibly configurable beam distribution, the laser beam can be split, switched over, disabled, and measured. In this way, it is possible to use the solid-state laser at one or more processing stations, with a time or energy split. This enables multiple welding processes to be performed at the same time or with a time delay. The modular layout enables subsequent repairs or extensions in the field.

TruPulse laser precision welding
Finely graduated

In terms of power, energy, or focusability the TruPulse series covers the full spectrum of parameters for laser precision welding. The parameters for pulse energy and pulse duration are variable – so the laser device can be accurately designed for your application and used with flexibility during operation. With a maximum pulse power of up to 10 kW, pulse durations ranging from 0.2 to 50 ms and pulse energies of up to 120 J, the TruPulse lasers are perfect for many applications – for both manual and automated tasks.

Burst function of the TruPulse
Burst function

The pulse energy and average power normally limit the pulse frequency of a laser. The burst function enables the frequency and the average power to be significantly increased for a short period at the same pulse energy level. You can therefore minimize the welding time per processing cycle and increase your productivity.

Intuitive operation as a result of the TruControl control


TruControl is the control software for your TRUMPF solid-state laser – for quick and simple operation. You can program pulse shapes individually to match your application. The laser power is controlled in real time to ensure maximum reproducibility of your process results. In order to retrace important quality data of your produced parts even years later, the optional DataStore software module records all data relevant to quality.

If external controls are present, TruControl will communicate with them via all standard interfaces. Inputs are made via the touchscreen of the operating panel or via a panel PC. You can integrate your laser into the network via Ethernet and connect multiple PCs.

With TRUMPF you have the ability to adapt your solid-state laser to your installation and operating situation with flexibility. This applies, for example, to all beam guidance components and the control. You also have several options for the cooling water supply. Interfaces for different optics are provided right from the start. To save costs, your beam source can supply several work stations at the same time. The TRUMPF Remote Service helps you to ensure your system remains available, anywhere and at any time.

Modular system of optical components
Flexible, integrated beam guidance elements

There are many options available to you for adapting the laser to your individual situation with flexibility. In addition to the laser power and pulse energy, you can also choose the number of fiber outlets up to a total of six. The laser power is regulated for each outlet. The plug & play optical laser cables can be easily connected to different work stations. This allows multiple work stations to operate simultaneously with split laser power or one after the other at full laser power. The modular layout enables field repairs to be carried out on site, as well as making the system suitable for retrofitting.

TRUMPF laser network

With the laser network, you can network one or more lasers with up to six work stations in each case. In the process, your laser either splits its power to multiple stations, or it supplies them in turns with full power. This will even enable you to combine different applications, such as welding and cutting. The overall availability of your manufacturing systems will increase as a result due to simple redundancy concepts.

Convenient and flexible control

The TruPulse can be equipped with virtually all standard fieldbus interfaces for control and actuation. The following are also available: real-time interface, parallel digital I/O, interface for process sensor systems, OPC UA software interface, and analog input boards.

The TruPulse has an interface to connect TRUMPF processing optics, such as the PFO 20.
Interface for intelligent optics

Intelligent optics can be synchronized with your laser via a dedicated interface. For example, the CFO focusing optics or PFO scanner optics can be used optimally for your purposes. You can program the processing optics easily via the laser control system. You do not need additional PCs or control systems.

Remote Services

In the event of an error, TRUMPF service experts will remotely access your laser via a secure remote connection. In many cases the error can be remedied this way, or the configuration of the laser can be modified in a way that enables you to continue manufacturing until the spare part arrives, thus minimizing idle time in production.

Flexible cooling options

For cooling of the laser you can select between water/water or water/air compressor cooling, which means that the TruPulse laser can also be used at high ambient temperatures. If you already have your own cooling circuit in place, you can use it in conjunction with a plate heat exchanger.


The WeldAssist database provides you with welding parameters for various materials and focal diameters. This makes set-up easier for frequently changing laser applications.

Due to the TRUMPF sensor systems, your production will always be effective and cost-effective. The sensor products VisionLine, CalibrationLine or integrated pyrometers ensure stable processes by monitoring all the processes in laser production, playing an important part in your process reliability. Processing continues uninterrupted during measurement – no interruptions are required, saving you valuable production time.
