Passive Alf
The Laser Safety Welding
Helmet for Hand Held Laser Welders
- Designed specifically to protect the eyes and face of the welder and to protect co-workers from stray laser
radiation outside the enclosure - Ensures user wears helmet with closed visor and closed enclosure door before firing laser
- Filter in visor reduces light transmission to safe levels
- Safety Interlock Controlled
- Laser enabled only when helmet is worn and the visor is down
- Door interlock switch must also be closed
Passive Alf is the name attributed to the latest safety helmet designed specifically for hand held laser welding applications Although it looks similar to conventional designs, the passive laser welding helmet has inbuilt laser wavelength filtering to prevent the user absorbing high amounts of laser radiation emanating from the laser welding operation. User safety is paramount and using this helmet will reduce the amount of laser energy transmitted to a safe level in the event that there is either direct hit or a high level of reflection from the laser welding process. The helmet has internal micro-switches that must be closed for the laser to be enabled. These dual channel switches are closed by the user simply wearing the helmet and closing down the visor. If the visor is opened or if the helmet is removed, the laser is immediately disabled. In addition the interlocked enclosure door must also be closed to enable the laser.
