Ensuring Operator Safety with Every Weld – Guidelines for Using Simass Responsibly
Although the Simass Base Unit itself does not emit laser radiation, it forms the structural foundation for laser welding systems and often supports high-power laser heads, automation modules, and moving parts. Therefore, observing strict safety practices around Simass is essential to ensure operator well-being, equipment longevity, and compliance with international safety standards.
Here’s how to ensure safe daily use of the system:
Laser Safety Classification
Simass itself is non-emissive but is commonly used in Class 1 and Class 4 laser environments. The safety level of the overall welding setup depends on the connected laser head and whether safety enclosures or interlocks are in place.
- Recommended: Operate Simass within a Class 1 safety enclosure for maximum protection.
- Minimum Requirement: Ensure line-of-sight is shielded when used with open (Class 4) laser configurations.
Personal Protective Equipment (PPE)
- While sigma laser’s welding systems are 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.
| Task | Recommended PPE |
|---|---|
| Routine operation | No PPE required under closed housing |
| Maintenance (open casing) | Laser safety goggles (1064 nm rated) |
| Welding setup adjustments | Safety gloves, protective sleeves |
| Handling heavy components | Safety shoes, cut-resistant gloves |
| Optical cleaning or inspection | Anti-static gloves and lens-safe cloths |
Workspace Safety Requirements
- Ensure that the system is installed in a ventilated, dry, and stable area with proper clearance on all sides.
Install on a level, vibration-free surface to ensure axis stability.
- Avoid stacking materials around the enclosure that could block access or cooling airflow.
Avoid clutter around the system to allow proper access to emergency stop and power cut-off.
Ensure all users are aware of the Class 1 safety zone boundaries.
Place proper safety signage indicating laser equipment in use.
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.
Use only Sigma-certified coolant; regularly check coolant levels and look for leaks.
Never run the laser if coolant is low or the system indicates temperature warnings.
Keep all power cables secured and free from obstruction or wear.
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.
Power Cutoff: Located on the back panel — disconnects the full system from power.
In case of accidental exposure or incident, stop operation immediately and report to safety supervisor.
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.
