Chapter VII Introduction to HMI Operation
7.1 Introduction to HMI function
As for the handheld laser welding system operation panel (hereinafter referred to
as "HMI"), the 7cun configuration TFT touch screen is used, with beautiful interface
and convenient operation. The laser-related parameters can be set, respectively and
the real-time display of input/output IO state, alarm information and running state can
be realized on the main interface.
Refer to the following figure for the HMI main interface.

Enabling the
safety lock
[Swing Disabling]: The galvanometer motor swing is enabled or disabled by the
button.
[Enabling of Safety Lock]: The safety lock can be enabled or disabled by the
button. When the safety lock is enabled, the emission of laser will stop if the plumb
joint fails to touch the welding material at the moment of welding.
[Disabling of Automatic Wire Feed]: Whether automatic wire feed is performed
at the moment of welding can be controlled by the button. Automatic wire feed will
arise only when the laser emission is allowed
[Forbidding Laser Emission]: Emission of laser can be allowed or forbidden by
