Optional extended X, Y axis electric moving plat form, suitable for use in welding areas beyond the scope of galvanometer scanning.
The galvanometer Z-axis is electrically adjusted for easy focus adjustment.
Optional CCD vision system for easy observation of welding results.
 

High-efficiency laser spot welding or sealing welding for new energy, medical devices, aerospace,auto parts, instru-

ments 3C, IT electronics, jewelry, Hardware structural parts and other products.

Suitable for welding of precision stainless steel, carbon steel sheet, copper foil, aluminum foil, gold, silver and other

metals or alloys; also can be used welding between a variety of dissimilar materials.
      This machine comes with a 7 inch industrial screen, which is connected to the host computer through the uart interface to realize equipment control and status monitoring functions.
There are 5 operation pages, namely, main interface, advanced settings page, process parameters page, machine information page and manufacturer settings page.
(1) Main interface
This page is the display page under normal working condition, which can realize the machine switch control, common process parameter setting, working status information and alarm prompting function.


(2)Process Interface
   This interface can save a variety of parameters with the process. This function is not often used, because the main interface can be used to adjust the parameters directly, the most commonly adjusted parameters are output power and swing width. This interface can be used according to the customer's habit.

 

Button Name	Functional Description

Button Name	Functional Description
maximum power	Set according to the actual laser power, this parameter has been set in the factory, no need to change.
delayed opening of the eyes	Press the torch trigger button, the delay time of the laser light, the role of this parameter is: after pressing the torch trigger button to blow first, and then light, so that the original residual in the torch stainless steel tube and welding nozzle fumes and dust discharged, so that the torch stainless steel tube and welding nozzle as far as possible to maintain a clean, to avoid dust adherence in the protective lenses, to prolong the life of the protective lenses.
off-gas delay	After releasing the trigger button of the welding torch, the protective gas delay blowing time, the role of this parameter is: after releasing the trigger button of the welding torch, the laser is turned off, but the protective gas delayed shutdown, so that the welding torch stainless steel tube and welding nozzle inside the fumes and dust discharged, so that the torch stainless steel tube and the welding nozzle inside the torch as far as possible to keep clean, to avoid the dust adherence in the protective lenses, to prolong the life of the protective lenses.
initial power	After pressing the trigger button of the welding gun, the laser power first rises to the initial power and then to the set power, so that the laser power has a slow rising process to protect the laser and prolong the life of the laser.
Power Rise Time	Time from pressing the torch trigger button until the laser power reaches the initial power.
Wire break power	The output power of the laser at the moment of releasing the trigger button of the welding gun, this power is set according to the size of the welding wire diameter, which facilitates the melting of the welding wire at the end of welding.
Power down time	Laser power from the broken wire power to 0 time, the above four parameters are mainly to realize the laser power slow rise and slow fall process, reduce laser damage, extend the life of the laser.
blackout delay	Time for light to continue to come out after releasing the torch trigger button.
filament return delay	After releasing the trigger button of the welding torch, the wire will have an action of pumping back and sending out again, mainly used for melting the welding wire.
swing center	Note that this parameter is more commonly used in everyday welding. When welding the wire needs to be located in the middle of the laser swing width, when the wire offset, you can adjust this parameter. But you need to make sure that after adjustment, observe the gun head red light has been all out of the mouth, otherwise there will be part of the laser hit the gun head copper mouth wall, resulting in copper mouth damage.
PWM frequency	This is a laser parameter and does not normally need to be adjusted.
PWM duty cycle	This is a laser parameter and does not normally need to be adjusted.
Pulse Switch Pulse Off Light	Adjustment of out-of-close time and out-of-light interval in pulse welding mode.
Pneumatic Polarity Water-cooled polarity Laser Polarity	When an alarm corresponding to the item appears, try to change the polarity, and it will usually return to normal.
save	After modifying the parameters of this interface, click Save to take effect.
