Model 304 - Frame Fit-over Spectacle Special Darker
- Fits over most standard smaller prescription glasses.
- Model 304 includes high comfort and side-protection with still a relative wide view of vision
The glass is some darker but the absorption of laser welding light is lower than the standard glasses.
Looking in the melting pool is the biggest mistake which is made during laser welding.
The light you see is energy losses and you do not see any melting pool as the speed is too high!
