HMI Operation Introduction

HMI Function Instruction

Handheld laser welding control system operating panel (“HMI” for short) adopts a 7-inch configuration TFT touch screen with beautiful interface and convenient operation. It can set laser related parameters. On the main interface, the input and output IO status, alarm information and motion state can be displayed in real time. HMI main interface is shown in the figure below:

HMI Operation Introduction

Swing start: used to enable motor swing or stop it
Safety lock: it can be started or closed by the button. When the lock is enabled, during the welding, the laser will stop when the welding head does not touch the welding material.
Laser enable: Enable the laser before press processing on the gun head.
Light on/off: it can enable or close the laser. When it is enabled, GATE signal will be closed; when it is closed, GATE signal will be opened and PWM modulating signal output will be stopped.

HMI Operation Introduction

Parameter Setting

Parameter setting includes welding parameter, system parameter and advanced parameter.
Welding parameter: used to set the parameters related to laser and gas during welding.
Version No.: Different version can set multiple sets of welding parameters.
Power: Used to set the peak power of laser during welding
PWM frequency: used to set the frequency of laser PWM modulating signal
PWM pulse width: used to set the pulse width of laser PWM modulating signal
Duty cycle: used to set duty cycle of PWM signal with the range from 1% to 100%
Swing frequency: used to set motor swing frequency
Diameter: used to set the motor swing width
Gas on delay: when starting processing, users can set gas on delay. When the external start button is pressed, after blowing delay for some time, the laser can emit light.
Gas off delay: when stopping processing, users can set gas off delay. When processing is stopped, stop the laser first. After delay for some time, stop gas blowing.

System parameter: Used to set system parameter
Alarm signal enable: when it is enabled and the alarm is generated, welding will be stopped and the laser is closed; when the alarm signal is not enabled and the alarm is generated, the welding will go on.
PWM setting method: used to select whether the pulse width is effective or the duty cycle is effective in the welding parameter.
Wire feeding time: used to set the time of automatic wire feeding, which must be less than the gas on delay time
Wire drawing time: used to set the time of automatic wire drawing
Input port status: used to set the detection logic of various input IO in accordance with the actual situation of the machine. Otherwise, alarm will be triggered.

Advanced parameter: Used to set advanced parameter
Swing type: used to set swing types
Maximum frequency: set the maximum frequency of laser PWM signal. When PWM frequency set by welding parameter exceeds the maximum frequency, the frequency will be limited to the maximum value.
Maximum diameter: used to set the maximum diameter during swing. When the diameter set by welding.
parameter exceeds the maximum diameter, the diameter will be limited to the maximum value.
Diameter compensation: when there is a nuance in the length between the set diameter and the actual.
diameter, it can be modified by this parameter. When there is no need for compensation, it is usually set as 1.
Focal length: used to set the focal length of the welding head lens, which should be in line with the actual machine parameter. Otherwise, it will make the actual diameter incorrect.
Maximum deflection angle of galvanometer: used to set the range of deflection angle of galvanometer Slow rise time: used to set the time that the laser analog voltage(0-10V) rises from 0 to the maximum power when the it is enabled.
Slow fall time: used to set the time that that laser analog voltage (0-10V) falls from the maximum power to 0 when it is stopped.
X axis offset: when there is a slight offset in the center of X axis, it can be modified by this parameter.
Y axis offset: when there is a slight offset in the center of Y axis, it can be modified by this parameter.
X axis correction coefficient: when there is a nuance in the length set by X axis and the actual length, it can be modified by this parameter. When there is no need for modification, it is usually set as 1.
Y axis correction coefficient: when there is a nuance in the length set by Y axis and the actual length, it can be modified by this parameter. When there is no need for modification, it is usually set as 1.
Straight line coefficient: it can adjust the swing speed at both ends and in the middle position when the straight line is swinging with the adjustable range from 0.01 to 1. When it is set to be 1, the speed at both ends is the same with that in the middle; when it is set to be as small as 0.01, the swing speed at both ends is quick, but slow in the middle.
