ALV 300F
A compact German-made laser welding system supporting Nd:YAG and fiber laser configurations, pulsed and CW operation, and flexible welding spot sizes.

- 120–300 W Average power
- 3–9 kW Peak pulse power
- Nd & fiber Laser options
- Pulsed / CW Operating modes
Product description
The ALV 300F is used for stainless-steel and carbon-steel fabrication, galvanized-steel and aluminum assemblies where supported by the model and process data, sheet-metal enclosures and frames, kitchen and furniture fabrication, and general engineering welding assemblies. To operate the system, inspect the laser head, cooling system, and gas supply before startup. Prepare and securely fixture the workpieces, select the welding program and required laser configuration, and set the laser power, pulse duration, frequency, and operating mode. Select the required welding spot and focal distance, then perform a test weld before starting the welding process. Monitor the weld and machine status during operation, inspect the finished weld, clean the workpiece and work area, and stop the system according to the operating procedure.
