Facula: Positive and negative defocus from 0.1~3.0mm
Attention: This option is locked. Please adjust facula by turning the grey knob on the other end
of laser cavity.
2-5 Control Panel
Precautions:
Please read instructions carefully before starting up the Laser Welding Machine.
Operation instructions
The two Select buttons are used for selecting the menu on the screen; the change of the
parameters is controlled by the Adjust button on the panel. When the cursor is moved to the
corresponding place, the related button can be pressed to set the required parameters.
Width:
It displays the pulse width of the laser discharging per millisecond, minimum value 0.1 and
maximum value 20. The wider the pulse width is, if the working voltage is the same, the
higher output energy of laser will be. Press the Up/Down key on the control panel for one
time, the pulse width of laser discharging will be increased or decreased by 0.1 millisecond.
Frequency:
It displays the frequency of laser discharging, with the unit of HZ. The higher the frequency is,
more times laser will shoot in unit time. Press the Up/Down key on the control panel for one
time, the pulse width of laser discharging will be increased or decreased by 1HZ.
Light shielding:
When the pedal switch is closed and the word “laser” is displayed in the screen, the liquid
crystal light valve can shield the flashing light. Under non-
work conditions, the word “laser”
won’t be displayed.
Working current:
It displays the discharging current for the laser. When the pulse width is identical, the higher
the working voltage is, the higher laser output energy will be. Press the Up/Down key on the
control panel for one time, the discharging current for the laser can be increased or
decreased by 1A, ranging from
50
—600A.
