Laser welding is a powerful industrial process, and safety is paramount. The Sidanus Light is built with a Class 1 laser enclosure, meaning it is safe for operation in standard environments without exposing operators to laser radiation — but proper usage, training, and awareness remain essential.
Here’s how to ensure safe daily use of the system:
Laser Safety Classification
- Class 1 (Fully Enclosed):
The system’s design prevents any accidental exposure to laser radiation during normal use. Internal interlocks prevent laser activation if panels are open or improperly sealed.
Personal Protective Equipment (PPE)
- While the Sidanus Light is enclosed, use of laser-rated safety glasses (wavelength 1064 nm) is advised during setup or service with open panels.
- Gloves and protective clothing may be required when handling sharp, hot, or heavy workpieces.
Workspace Safety Requirements
- Ensure that the system is installed in a ventilated, dry, and stable area with proper clearance on all sides.
- The floor must be level to support accurate motion of the XY table and C-axis.
- Avoid stacking materials around the enclosure that could block access or cooling airflow.
Electrical & Cooling System Safety
- Power supply should be 3-phase 380V, grounded properly.
- Only trained personnel should access internal components or electrical cabinets.
- Use only approved coolant fluids in the cooling system to prevent corrosion or leaks.
Software & Control Warnings
- The Sigomatic interface is equipped with real-time alerts for:
- Overheating
- Water level drop
- Lamp fault
- Interlock failures
- Never bypass safety interlocks or override alarms.
Emergency Procedures
- An emergency stop button is located on the front control panel. All motors and laser output halt instantly when pressed.
- Keep a Class C fire extinguisher nearby for electrical incidents.
- Ensure all staff are briefed on emergency shutdown and evacuation procedures.
Training & Access Control
- Only trained personnel should operate or maintain the machine.
- Use login access levels on the Sigomatic interface to restrict advanced settings to supervisors or engineers.
- Display safety signage around the unit to maintain operator awareness.
Safety Summary
While Sidanus Light is designed for maximum safety with its enclosed Class 1 architecture, proper training, routine checks, and workspace discipline ensure the system runs safely for years to come.
