Miller Electric‘s Performance Series line of auto-darkening welding helmets include three arc sensors, quick-release front cover lens holders with a rubber spatter gasket and lens controls at the bottom of the lenses. Both the Motorsports helmet and the Fire Storm helmet feature Miller’s auto-on and grind mode. Auto-on eliminates accidental arc flash by detecting the arc even if the helmet hasn’t been used for awhile. Grind mode allows the helmet to be used as a protective shield, preventing the lens from darkening while grinding.
