Product description
The ALFlak 900 F is specified 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. For operation, inspect the laser head, lens cooling system, and gas supply before startup. Prepare and securely fixture the workpieces, select the welding program and required process parameters, and set the laser power, operating mode, pulse duration, and other applicable parameters. Check the focus and nozzle position and perform a test weld before starting the welding process. Monitor the weld and machine status during operation, inspect the finished weld, clean the work area, and shut down the system according to the operating procedure.
