1. Clean the Equipment Surface and Work Area

Wipe the equipment casing and operating table with a dry, soft cloth to remove dust, oil, and metal debris, and prevent impurities from entering the equipment.
Clean the workbench from welding slag and spatter (use a dedicated brush or vacuum cleaner) to prevent misalignment of the workpiece and scratches on the surface.
Check the cooling system's water tank to ensure the water level is within the scale and clear. (If turbid, replace it promptly to avoid clogging the pipes.)

2. Check the condition of core components

Laser head and optical lens: Inspect the protective lens for stains, scratches, or burn marks (inspect before each use). If contaminated, gently wipe it with a special lens tissue dipped in anhydrous ethanol. If damaged, replace it immediately (the protective lens is a consumable part; regular replacement prevents laser energy loss or damage to the focusing lens).
Fiber optic connector: Check the connection between the optical fiber, laser generator, and laser head for looseness and ensure the connector surface is clean. If dust is present, wipe it with a dedicated cleaner to prevent unstable laser transmission. Moving Parts: Check the robotic arm and worktable rails for foreign objects and ensure smooth manual movement. If any jamming occurs, clean the rails and add lubricant (avoid using regular motor oil to prevent corrosion).

3. Parameter and Safety Check
Before starting the machine, verify that the laser power, welding speed, and other parameter settings are appropriate for the day's work to avoid equipment overload caused by incorrect parameters.

Check the sensitivity of the emergency stop button and safety door interlock (the laser will only fire after the safety door is closed to ensure safe operation), and ensure that the cooling fan is operating properly.
