Safety Light Emission System

This machine is equipped with a triple-layer safety system:

1. Safety Ground Lock — Laser can only emit when the welding gun physically touches the workpiece, preventing accidental firing
2. Gas Detection System — Automatically alarms if the gas cylinder is not open or gas flow is too low, protecting the torch lens
3. Double Safety — Welding gun trigger button AND laser shutter both must be active to emit light

Safety Precautions

• ⚠️ Always wear laser safety goggles during operation
• ⚠️ Never look directly at the welding gun output port
• ⚠️ Do not use in dim or dark environments
• ⚠️ Maintain optical cable bending radius greater than 200mm
• ⚠️ Handle welding torch carefully — it is a precision component
• ⚠️ When welding copper or aluminum (highly reflective materials), tilt the torch — never hold perpendicular to workpiece
• ⚠️ Ensure no one stands on the opposite side of the welding direction
• ⚠️ All repairs must be performed by qualified professionals only

Common Troubleshooting

Problem	Solution
Laser source alarm	Check red light output, chiller temperature & water flow, QBH connection
Chiller alarm	Check if chiller is on, check water level, clean filter, check for leaks
Gas pressure alarm	Check if gas valve is open, check flow rate (>10 L/min), check for leaks
No laser emission	Check alarms, check lens cleanliness, check trigger & ground lock signals, check PMW & Laser Enable voltage (24V)
Weak laser energy	Clean protective lens, readjust focus position
Protective lens frequently damaged	Ensure gas flow >10 L/min, keep torch angle <70° from workpiece — never weld at 90°
Copper tip overheating	Normal for aluminum welding; check laser centering and lens cleanliness
Indicator light flashing randomly	Check grounding, check for large electrical equipment interference nearby
