Many customers who bought our laser welding machines before have feedback that they are a bit vague about the buttons and parameters on the control panel of the fiber laser welding machine.

  • For gas control, install proportional valve, effective percentage control.


  • The display of the trigger button of welding head.
  • The WELDING button is on when the trigger button pressed by user.


  • lt 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.


  • Refers to the state of the laser head motor.
