Working Mode
Shenzhen Qilin Laser Application Technology Co., Ltd.
FGAP : Control of laser switch. When in normal use, turn on FGAP button to connect laser
light signal. ( Connection of laser source will be cut down after 15 minutes of no
working)
Gas : For gas control, install proportional valve, effective percentage control.
Fillings : Control of feeder feeding, switch of feeding function.
Welding: The display of the trigger button of welding head.
The WELDING button is on when the trigger button pressed by user.
Connect : It is the indicating of loop signal of head to the metal.
When the gun head touches the metal plate which with alligator clip, the CONNECT
button is on. This button is for protective of laser light. Short connection is
prohibited.
Motor : Refers to the state of the laser head motor.
The light is on when the motor is normally connected, and when the motor is not
working, the MOTOR button is off and the LCD screen of welding head shows the
alarm signal E, it means the laser light signal is locked and the triggle button of
welding is invalid.
Control Section for Screen:
Laser Control Motor Control Gas Control
1. Laser Control
Power(0-100%): Choose appropriate percentage according to different materials.
The frequency is suggested at 3000-5000hz.
Frequency (50-30000HZ)
Duty Cycle(1-100%): According to the requirements of the welding surface
2. Motor Control
Working Mode:
Frequency: Refers to the adjustable motor speed (2-46hzms), 1HZ=10 laps
Width: Wobble size,（0.2-5mm）adjustable.
Tips:
1) ● mode: refers to the state when the motor does not swing and the spot is minimal.
Strong penetration, can be used for penetration welding, overlap welding or
thick materials.
2) mode: it means to swing a motor, connect the points into a line.
Can adjust the width of the mark, concentrate the energy density, also can have
a certain penetration of the thick plate, the use of positive fillet welding.
3) mode: they are the welding of swinging 2 motors, forming the point
into different beam shapes. Can adjust the diameter. Uniform energy density, obvious
advantages of thin plate welding, the minimum 0.3mm materials, for the use of butt
welding, Yin fillet welding.

3. Gas Control
Gas advance//delay:
It is recommended to set it around 150ms to protect the welding dust from
polluting the protective lens.
Proportional valve:
when the proportional valve is connected, the gas can be controlled 100%
effectively.
Power Setting for slowly rising & falling
1. Control laser power slowly rise and fall to protect protective lens and better
welding effective.
2. Rising to full power in the time you set slowly, can be chosen from 20-400ms
3. Falling to 0 power in the time slowly, can be chosen from 0-400ms

Position Setting for Red Light
1. Adjust the Axis of X and Y motor reflecting lens to change the red light offset
position.
2. The adjustment radius of the laser center point is 5mm.
3. Make sure all motor circruit are normal before adjustment to avoid wrong
operation.
