optrel - Model e670 -High End Welding Helmets
The modern welder needs protective equipment optimised for maximumperformance and efficiency. In order to allow welders to work with asfew interruptions as possible, welding machine manufacturers are increasinglyadding remote control to their welding torches. But how doesthis affect the welder who needs to control his shade level? If the welderhas to manually adapt his shade level, the process will be interruptedonce more. If he leaves the shade level setting unchanged, comfort levelsplummet – e670 is the perfect solution.
Unique sensor technology allowsthe darkening filter to automaticallyselectthe shade level and continually adapts this to the relevant applicationand arc intensity during welding. Fine adjustment also allows thewelder to adapt the automatically selected shade level to his personaleyesight sensitivity. All of which means the welding process isn’t interruptedat all. Maximum efficiency and comfort are guaranteed.
