Closed Laser Welding Device ALW
The ALW is a comfortable, ergonomic, and compact seated workstation that offers plenty of legroom, and which can be adjusted to the height of the operator via
the height-adjustable foot plate. The observation lens offers a variable viewing angle from 10° – 50°, thus ensuring
comfortable working. The closed, laser-proof housing makes the ALW a laser-protected workplace that can be used in a
normal production environment without additional safety precautions.
Easy to Use
The laser system is easy to operate. In addition to configuring via the display, the laser parameters can be adjusted
via the patented multifunction footswitch or adapted accordingly during welding.
The large doors of the ALW can be opened wide. This facilitates easy loading.
The ALW in a few words:
- Robust housing, also well suited for automatic, programmed laser welding
- Ergonomic seated workstation for fatigue-free working
- Closed system, thus usable in any room
- Precision joystick for optimal work results
- All-in-one system (table, laser, extraction, safety)
- Plenty of space inside and wide opening doors
- Easy to operate
Precise Movement System
A large and stable work plate holds workpieces weighing up to 350/400 kg and ensures their precise positioning.
The joystick for movements along the X, Y, Z, and R axes reacts very accurately. All axes directly follow the joystick movement.
Movements are made
- manually by joystick,
- semi-automatically,
- or in automatic mode (ALW 200/300) programmed with the WINLaserNC software.
The ALW 200/300 enables programmed series production and welding on materials that are difficult to process, such as aluminum, precious metals,
titanium, or sensitive alloys. It can be used for welding wires from 0.2 to 0.8 mm. Automatic wire feeding (LAFet) can be installed. Included in the scope of delivery of
the ALW200/300 is the Ergotubus, which ensures the ergonomic alignment of the microscope. This system allows you to work pulsed at up to 100 Hz under visual control.

ALFT-HDMI camera system
For displaying the welding process on an external monitor The camera system is specially made for ALPHA LASER systems and is mounted below the laser's microscope attachment. Includes power supply, HDMI cable, and laser connection cable. HDMI recorder for recording not included in scope of delivery.
Ergo wedge 5°-25°
Enables tilting of the binocular for ergonomic working
Halogen bulb (flexible)
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 (only ALW 200/300)
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
Turn and tilt objective (only ALW 200/300)
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
