Page 6: Safety Instructions
Safety Instructions Explanation of DANGER! Safety Instruc- tions Indicates an immediate danger. ▶ Death or serious injury may result if appropriate precautions are not taken. WARNING! Indicates a possibly dangerous situation. ▶ Death or serious injury may result if appropriate precautions are not taken. CAUTION! Indicates a situation where damage or injury could occur. -
Page 7: Intended Use
Your personal safety is at stake! Intended Use The LaserHybrid head is to be used exclusively for its intended purpose. The LaserHybrid head is intended exclusively for LaserHybrid welding of aluminum, CrNi and steel materials. Any other use does not constitute proper use. The manufacturer is not responsible for any damage resulting from improper use. -
Page 8: Personal Protective Equipment
Personal Protect- Please take the following precautions for your own personal safety: ive Equipment Persons present in the sealed cell for the LaserHybrid process must wear rigid, wet-insulating footwear protect hands with appropriate gloves (featuring electrical insulation and thermal protection) protect their eyes from laser beams by wearing regulation-compliant safety glasses for lasers. -
Page 9: Danger From Flying Sparks
Ensure there is a sufficient supply of fresh air with a ventilation flow rate of at least 20 m³ per hour. Please observe the safety and maintenance information for the shielding gas cylin- der or the main gas supply. When no welding is taking place, close the valve of the shielding gas cylinder or the main gas supply. -
Page 10: Particular Hazard Areas
Persons with pacemakers must seek advice from their doctor before staying in the imme- diate vicinity of where the welding work is taking place. Supporting measures to avoid EMC problems: Grid power supply If electromagnetic interference occurs despite a grid connection that complies with regulations, take additional measures (e.g., use a suitable grid filter). -
Page 11: Informal Safety Measures
Special regulations apply in areas where there is a risk of fire or explosion – observe relevant national and international regulations. Power sources for work in spaces where electrical hazards pose a greater risk (e.g. the boiler room) must be marked with a (Safety) sign. The power source should not be loc- ated in these types of spaces, however. -
Page 12: Safety Measures In Normal Operation
Use instructions and checks within the company to ensure that the vicinity of the work- place is always clean and organized. Only set up and operate the device in accordance with the degree of protection shown on the rating plate. When setting up the device, ensure an all-round clearance of 0.5 m (1 ft. -
