You weld for 6 to 8 hours a day, igniting the arc several hundred times. Eye protection is therefore essential. Our automatic welding helmets offer a particular advantage here: normally, there is a delay of a few fractions of a second between each ignition and the automatic anti-glare cassette closing. However, Fronius welding helmets such as the Vizor Connect use Bluetooth® Low Energy technology to ensure that the welding helmet darkens before the arc is ignited.
