The Vizor Connect welding helmet from Fronius USA LLC communicates with a power source via Bluetooth. This means that it darkens prior to ignition rather than waiting until the arc is lit. This protects users against the abrupt flash of light that appears before the helmet darkens. The helmet also eliminates interference from external light and reliably darkens even in demanding welding situations. The auto-darkening filter cartridge remains in place even at the lowest currents and if the arc is concealed and in constrained positions, as long as the arc is burning.
