Troubleshooting

Step 1: Confirm Laser Is Enabled
Make sure the laser button is enabled and the laser ready in the control software (Red triangle should appear)
Check that wattage, frequency and pulse settings are properly set

Step 2: Check Trigger
Inspect gun head and cable for any visible damage
* Trigger is a double tap and hold*

Step 3: Verify Safety Conditions
Confirm all safety interlocks are satisfied
Make sure the machine is properly grounded
Check that no emergency stop is engaged

Step 4: Inspect Fiber Cable Connection
Ensure the fiber cable (QBH connector) is securely connected
Do not force the connection—make sure it is properly seated
Check for visible damage or debris at the connection point

Step 5: Check Lenses
Clean or replace the protective lens in the gun head. Also check the focus and collimating lens for any scratches, burn marks or debris. Replace if needed.

Step 6: Look for System Warnings or Errors
Check the display for any alarms or error messages
Resolve any active faults before attempting to fire the laser

Step 7: Test in a Safe Environment
Attempt to fire the laser on appropriate material
Ensure proper distance and positioning

Still not firing?

If the laser does not fire after completing these steps, contact support and provide machine model, serial number and the issue happening.

If your laser machine is not turning on, follow the steps below to identify the issue. Most startup problems are related to power supply, safety switches, or simple connection issues.

Step 1: Check Power Connection
Ensure the power cable is securely plugged into both the wall outlet and the machine
Verify the outlet is working (test with another device if needed)
Avoid using extension cords if possible

Step 2: Verify Main Power Switch
Confirm the main power switch is turned to the ON position
Some machines may have multiple switches (rear breaker + front panel)

Step 3: Release Emergency Stop
Check if the Emergency Stop (E-Stop) button is pressed
If pressed, twist or pull it to release

Step 4: Confirm Correct Voltage
Make sure the machine is connected to the correct voltage for your machine.
Using the wrong voltage may prevent startup or damage the unit

Step 5: Inspect Breakers and Fuses
Check your facility breaker panel for a tripped breaker
Inspect the machine’s fuse (if accessible)

Step 7: Look for Signs of Power
Do any lights, fans, or the display turn on?
No response at all: likely power supply issue
Partial power (fans/lights but no screen): possible internal or display issue

Still not turning on?

If the machine shows no signs of power after completing these steps, contact support and provide machine model, serial number and issues that is happening.

If your laser is firing but not cleaning effectively or performance seems inconsistent, follow the steps below. Most performance issues are caused by incorrect settings, lens condition, or technique.

Step 1: Check Settings
Ensure wattage is set appropriately for the material
Adjust the scan speed and the frequency in small intervals (the lower the number, the more aggressive the cleaning will be)

Step 2: Inspect the Protective Lens
A dirty or contaminated lens is one of the most common causes
Look for dust, residue, or burn marks
Clean the lens using proper materials and method

Step 3: Check Working Distance
Maintain proper distance between the laser head and surface
Too far or too close will reduce effectiveness
Keep a consistent distance while operating

Step 4: Adjust Cleaning Speed
Moving too fast will reduce cleaning power
Slow down your movement for better results
Use steady, even passes

Step 5: Confirm Material Type
Different materials require different settings
Thick coatings may require multiple passes
Some surfaces may not respond well to laser cleaning including light paint colors

Step 6: Check for Inconsistent Output
If power seems to fluctuate:
Inspect fiber cable for damage or sharp bends
Ensure all connections are secure
Check for overheating or system warnings

Still experiencing weak performance?

Contact support and provide machine model, serial number and the issue happening.
