If you need assistance with aligning your laser machine, this article will guide you through the process using the Wattsan 6040 LT. Proper alignment ensures optimal performance, improving precision and efficiency in cutting and engraving.
Setting the controller
Before beginning the alignment process, you must configure the controller. Navigate to the “Menu” and select “Functions Setup.” Then, choose “Laser” followed by “Laser Time.” Set the duration to 80+ seconds and press “Right.” This adjustment enables the laser to pulse with short-term radiation. Next, on the corresponding control panel, set the power between 20% and 25%, and you are ready to begin alignment.
Aligning the first mirror
To start, apply two to three layers of masking tape over the window in front of the first mirror. Using a single layer may cause the tape to catch fire. Press the “Pulse” button to emit a short burst of laser radiation. Observe the imprint on the tape—your goal is to adjust the mirror’s position so that the entire laser beam strikes the window.
Aligning the second mirror
Apply masking tape to the second mirror and move the laser head closer to the first mirror. Press “Pulse,” then move the laser head to the opposite side and pulse again. If the two laser marks do not align, use the three adjustment screws on the mount. Each screw alters the mirror’s angle in a specific plane. Gently turn the appropriate screw and pulse again to see the changes. Continue adjusting until the laser spots align when the laser head is moved across its range.
Aligning the third mirror
The third mirror is crucial, as the laser beam must strike the center of the window to ensure maximum efficiency. Misalignment at this stage can lead to defects in cutting, reduced power, and uneven or burned edges. Apply masking tape, pulse the laser, and move the laser head to the opposite side for another pulse. If the beam is hitting at an angle, adjust the mirror or reposition the laser tube. Moving the laser tube slightly alters the beam’s trajectory, allowing for fine-tuning.
Adjusting the focusing lens
The final step is aligning the third mirror with the focusing lens. Apply adhesive tape to the nozzle, pulse the laser, and examine the imprint. The goal is to ensure the laser beam passes precisely through the center of the mark. The imprint should be a small, round dot—any oval or curved shape indicates misalignment.

Finalizing the alignment
To verify alignment, place a piece of plywood under the laser head and set the focal distance. Increase the power to 60%–70% and press “Pulse.” If the alignment is correct, the imprint will be clean and precise. Once confirmed, secure all screws by holding them in place while tightening the securing nuts with a spanner. Avoid over-tightening, as this could damage the screws. Finally, perform one last check to ensure everything is properly aligned.
Conclusion
A well-aligned laser machine guarantees consistent cutting quality across the entire working area. By carefully following these steps, you can maintain precision, efficiency, and optimal performance in your laser operations. Regularly checking alignment and making minor adjustments when necessary will help extend the lifespan of your equipment and improve overall productivity.
