SENFENG has successfully installed and provided operator training for the 4020H 20kW fiber laser cutter at a facility in the United States. The entire process was expertly managed by after-sales engineer Mr. Gao Rui, who oversaw the machine assembly, electrical setup, calibration, commissioning, and operator training. Thanks to his thorough support, the installation was completed seamlessly, and the machine is now fully operational.

Site Preparation and Foundation Work

Dec 11, 2025
The first step involved assessing the placement of the machine and addressing any site-specific requirements. Adjustments were made to the foundation to ensure the anchor bolts were properly aligned. The engineer also took the necessary steps to reconnect the system, replace several damaged graphite boards from transport, and ensure the site was fully ready for the next phase of the installation.

Mechanical Setup and Calibration

Dec 12, 2025
The cutting head was carefully installed, and the wiring was connected. Adjustments were made to the cable chains to accommodate the three gas lines. Once the electrical setup was complete, the water cooling system was fine-tuned, and the necessary components were installed, completing the mechanical setup by the end of the day.

Electrical Integration and System Setup

Dec 14-15, 2025
The machine’s electrical wiring was successfully connected, and the system integration process went smoothly. Network setup was completed, including the addition of a switch to connect the laser cutter, monitoring systems, and other peripherals. Additionally, the air filter and nitrogen fittings were installed during this phase.

Power-On, Troubleshooting, and Testing

Dec 16-18, 2025
The system was powered on for testing, and it performed well with successful test cuts on a variety of materials such as stainless steel and carbon steel. The machine was tested with different gases, including air, nitrogen, and oxygen, and the cutting parameters were fine-tuned to achieve precise cutting results. The system was calibrated to perform optimally.

Operator Training and Software Setup

Dec 19-22, 2025
Comprehensive training was provided to the customer on machine operation, software usage, and routine maintenance. The training also covered troubleshooting techniques, setup of nesting, cutting parameters, and workflow management. All settings were customized according to the customer’s needs to ensure smooth and efficient machine operation.

Final Adjustments and Completion

Dec 23-30, 2025
Final adjustments were made to optimize the machine’s performance. An electronic pressure switch was installed to monitor air pressure, and the machine was fully tested to verify that all parameters were correctly adjusted. The laser cutter delivered excellent cutting results across various materials. The customer was extremely satisfied with the machine’s performance and cutting precision.

By the end of the installation process, the machine was fully operational, and the customer was fully trained and confident in using the 4020H 20kW fiber laser cutter for their production requirements. The after-sales engineer finalized the training and the machine’s acceptance, ensuring the customer’s complete satisfaction with the installation.
