Laser Source AL

The AL laser system is the most versatile device in our product range in terms of laser source, laser power, and equipment.

Lasers of the AL series can be individually configured and perfectly matched to the tasks. These are available as flash-lamp pumped lasers with outputs between 100–300 watts or as fiber lasers with outputs of 300, 450, 600, and 900 W.

Thousands of users depend on the reliable pulse-to-pulse behavior of the flash-lamp pumped laser and the high laser power that actually gets to the workpiece.

The laser systems can be integrated into existing machinery or used in conjunction with our work benches as a flexible professional solution. (see AL-IN or AL-TW)

We also offer a wide range of processing objectives for the AL. Whether you work with standard objectives, a 90° deflection objective, or a circular welding lens: the laser beam always precisely hits the desired spot on the workpiece.

Welding wires from 0,2 – 1,6 mm can be fed automatically

Left/right pivoting beam deflection unit +/- 110 °

Magnetic holding sphere

for quick and easy placement of the workpiece. The slip-stick effect between the ball and the socket guarantees a secure hold of the workpiece in any position.

Perpendicular objective - LED ring light

The LED ring light integrated in the objective provides optimal, even, and flicker-free illumination of the workpiece in daylight quality Focusing objective f = 150 or f = 300 available and protection glass 601-0690A

Rotary axis module

For welding cylindrical parts Tiltable for horizontal to vertical rotational movement. With chuck Ø 125 mm and inside diameter 24 mm

Switchable micro welding function

The switchable micro welding function reduces the welding spot diameter to very fine <0.1 mm.

Turn and tilt objective

Our tilting objective significantly eases work in difficult workpiece positions. In the objective's full 360° rotational range, the beam can be directed continuously up to 40° from the vertical. Moving the workpiece is not required. The beam can be conveniently directed towards difficult to access locations while maintaining an ergonomic work posture. With focusing objective f = 150, LED ring light and protection glass
