Portable Laser Spot Welding Machine – Main Interface
Main Interface Overview
Welding Number: Indicates the currently selected program number. Users can configure and store parameters for different welding processes. The system supports up to 19 custom program libraries.
Laser Power: Sets the laser output power for the current program, adjustable from 10% to 100%.
Frequency: Configures the pulse frequency of the current program, such as the number of laser pulses emitted per second.
Pulse Time: Defines the pulse duration of the current program, controlling the laser emission time under single-point energy output.
Modulation Frequency: Adjustable from 1 to 20,000 Hz, used to set the base frequency of the PWM modulation signal.
Duty Cycle: Provides stepless adjustment from 1% to 100%, enabling precise control of the modulation duty cycle for laser power.
Parameter Setting Interface
Front Shutter: Configures pre-lasing safety shielding (requires interlock with laser shutter). This function is inactive in this series and requires no user configuration.
Rear Shutter: Configures post-lasing safety shielding (requires interlock with laser shutter). This function is inactive in this series and requires no user configuration.
Open Air: Sets the delay time (ms) between the trigger signal and the actual laser output, with protective gas pre-flow to ensure adequate weld zone coverage.
Off Gas: Sets the duration (ms) for protective gas to remain activated after laser cessation, ensuring sufficient protection of the solidified weld.
Language: Switches interface language (Options: Simplified Chinese/English/Other).
Shutter: Enables or disables the optical safety shutter interlock function.
Air Valve: Manually activates or deactivates the protective gas supply.
