The welding helmet e684 from Optrel is an innovation with high quality, ease of use and functionality, which also fulfills important design aspects. Thanks to its infinitely variable shade level, the e684 is suitable for all arc, welding and cutting processes. It measures the brightness of the welding arc and automatically adapts the blackness value of the protection cassette accordingly. When opening the helmet, an integrated dimmer function creates a soft change from dark to light. The coating of the helmet results in a lower heat within the helmet; a respiratory protection system lowers the risk of occupational diseases. Different accessories are available to suit the needs of different use case scenarios, among them a breathing apparatus, an industry helmet adapter, neck and head protection as well as diopter lenses.
