 Figure 3.1-1, the front page of the control panel

① This interface can see the current process parameters (this page can not be
modified process) and real-time alarm information.
② The default is ON, the red light is LINE by default, and the welding mode is
continuous. When the enabling is turned off, the enabling signal will not be sent to the
laser and can be used to test the outlet function. Close the red light indicator, the
motor stops swinging, and the red light is a point to adjust the center position. The
welding mode is divided into continuous and spot welding. When the spot welding is
selected, the spot welding type needs to be set on the setting page.
③ The safety lock is divided into gray and green. When the metal clip is
clamped on the processing piece and the copper nozzle of the gun contacts the
processing piece, the 5 and 6 feet of the signal interface 1 are connected, and the
safety lock indicator is displayed as green. At this time, the light can be realized
according to the trigger.
④ Click on the upper right corner to switch to the cleaning mode.

The current process page provides 10 process items for users to save
parameters. The definition and scope of process parameters are described below:
 Figure 3.1-2 Control panel process page

click the box (red) to modify, click OK, and then save in the quick process,

click import (modify-save-import).

② The scan speed range is 2-6000mm / S, and the scan width range is 0 ^ 6mm. The
scan speed is limited by the scan width, which is: 10 scan speed / (scan width * 2)
1000 If the limit is exceeded, it automatically becomes the limit value. When the
scan width is set to 0, it does not scan (ie, a point light source)
(The most commonly used scanning speed: 300mm / S, width of 2.5-4mm).

③ The peak power should be less than or equal to the laser power of the parameter
page (if the laser power is 1000W, this value is not higher than 1000).

④ Duty cycle range 0 to 100 (default 100, usually not changed).

⑤ The pulse frequency range is recommended from 5-5000Hz (default 2000,

usually no modification).

⑥ Click the HELP button on the top right to get more relevant parameter
explanations.
⑦ After modifying the parameters, you can see whether the import is successful on
the home page

⑧ Reference process, can be used in the small program process reference

matters need attention:
① Some lasers cannot emit light with less than 10% power. When the peak
power of the process page is less than 10% of the maximum power of the laser on the
set page, all output signals are normal, but they may not emit light.
② The duty cycle is 100%, usually does not need to change, when the pulse
frequency does not work. If you need to use it, please adjust it according to the actual
requirements. Example: Peak power of 300W, duty cycle of 50%, and pulse frequency
of 1000Hz. At this time, the light cycle is 1mS,0.5mS to 300W light, 0.5 mS does not
light, the cycle, the air at the welding burst, abnormal sound is normal phenomenon.
The actual situation is based to the laser parameters.

⑤ communication status
 "Communication status" indicates the communication between the touch
screen and the motherboard. If not synchronized, check the screen cable.
"Anti-shake" is used to deal with poor contact with safe locks, which
range from 0 to 300 ms. Click "Device authorization box" to set the
parameter range on the password page as shown in Figure 3.9. The password
is "ffffffaa300" where "ffffffaa" indicates the lock anti-shake parameter
and cannot be changed. "300" means 300ms. The effect is that when the
trigger signal is normal and the disconnection time of the safety lock
signal is <300ms. Material welding used to deal with poor surface
performance and unstable conductivity (e. g. rust) is usually set to 0.

anti-shake password
"Motor driver temperature" and "protective mirror temperature" represent
the measured real-time temperature of the two parts. "Motor driver
temperature" affects the motor swing performance of the environment. If
the environment is poor, it will lead to the abnormal temperature increase,
affect the laser scanning speed, and then lead to the decrease of weld
quality. The lens temperature reflects the working state of the lens to
help determine whether the lens is damaged.
