Realistic colour perception is achieved due to a specially developed UV/IR filter. It features the patented autopilot function ShadeTronic®, based on a unique sensor concept that measures the brightness of the welding arc and automatically adjusts the correct darkness level of the anti-glare cassette. Equipped with a powerful solar cell and a rechargeable lithium polymer battery, it has a classification of 1/1/1/2 and uses optrel IsoFit® headgear. Battery life ranges from 300 to 500 charging cycles. Application: for all electric welding processes.
