Proper Shutdown Procedure for a Fiber Laser Welding Machine

Correct operation habits are as important as welding skills. Improper shutdown can shorten component life, damage optics, or create safety risks.

Whether using a standard unit or a laser welding machine 4 in 1, following a standardized shutdown sequence protects the laser source, cooling system, and welding head, ensuring long-term stability and consistent welding quality.

At Xianming Laser, we recommend this shutdown procedure for every laser welding machine for metal:

Step-by-Step Shutdown

Stop Laser and Reset Laser Button

Ensure the laser stops emitting and reset the button.

Prevents accidental firing, protects optics, and ensures operator safety.

Turn Off and Reset Chiller

Switch off the water chiller after the laser stops.

Prevents overheating, maintains stable temperature, and extends laser life.

Close All Gas Valves

Shut off nitrogen, argon, or air valves.

Avoids leaks, reduces waste, and protects pipelines.

Turn Off Main Power

Power down only after laser, chiller, and gas are off.

Protects electrical components and ensures safety.

Store Handheld Welding Head

Place on its bracket to protect lens, cable, and consumables.

Daily Maintenance Tips

Clean protective lenses regularly

Check water levels and filters

Inspect cables and connectors

Keep work area dust-free

Perform routine system checks

These steps help your fiber laser welding machine run efficiently and reliably.

Conclusion

Follow this sequence:

Stop laser → Turn off chiller → Close gas → Cut main power → Store welding head

A proper shutdown improves lifespan, safety, and performance. At Xianming Laser, we provide high-quality machines and technical guidance to help you get the best results every day.
