Safety Gear: Wear protective goggles (specific to laser wavelength) and heat-resistant gloves to shield against radiation and sparks . Ventilation: Ensure adequate airflow to avoid inhaling fumes from melted materials . Material Compatibility: Verify the welder’s suitability for your metal type (e.g., stainless steel, aluminum) to prevent poor fusion or damage . Distance & Stability: Maintain a steady hand and optimal focal distance to ensure precision and avoid accidental burns . Maintenance: Regularly clean lenses and check alignment to sustain performance .
