Welding helmet with flip-up panel

September 20, 2013

Classic VSi is a variable shade (shades 8-13) auto-darkening welding helmet with a flip-up panel that exposes a clear grinding shield that provides 180 degrees of vision. The helmet also features three independent arc sensors and X-Mode – a technology that electromagnetically senses the welding arc. This eliminates problems in which interference with the welding sensors can prevent the helmet from properly darkening.
