• Ultra-Crisp V1 (1/1/1/1) rated optics with enhanced colour recognition
• Illuminated digital LCD display/controls for superior visibility (auto dims when adjustments are not being made)
• Advanced digital controls with memory, cut mode, gradient & other functions
• External controls for shade adjustment & all modes: allows for instant & easy adjustment without removing or lifting the helmet
• Auto Controls: Option of Manual (user adjusts), or Auto shade / Sensitivity / Delay adjustment (helmets adjust settings automatically depending on arc intensity)
• Super-comfortable, wrap-a-round headgear with moulded rear pressure pad
• Lightweight (620g), up to 10% lighter than other digital wide-view helmets
• High-Impact tested and compliant with Australian standard AS/NZS 1337.1
• Auto-darkening lens complies with AS/NZS 1338.1
• Easy cover lens replacement
• Magnification lens holder - takes standard magnification lenses
• Reliable Power Source: Replaceable battery plus solar assist, efficient electronics for low power consumption
• Full-Laminate Lens Construction: Each layer in the electronic lens assembly is firmly laminated for superior optical quality and long service life. This is in contrast to cheaper lenses which are simply glued on the edge and, over time, are prone to contamination and failure.
• Lightweight, Durable and Shock Resistant shell

• Welding mode: Variable shade 9-14
• Cut mode: Variable shade 4-8
• Grind mode: Locks lens to light mode (shade 3), activate on/off via external button or internal controls
• Shade Lock: Switches off auto-darkening function & locks lens to a selected shade level (4-13), ideal for oxy cutting & similar processes where conditions may not be ideal for normal auto-darkening function
• Memory: Save up to 9 favourite settings (recalls shade, sensitivity & delay settings), with an ‘instant save’ function on external controls
• Delay (switching time from dark back to light after welding stops): Auto or Manual 0.1-1.0s
