    **Please be aware that this is the helmet shell only. It does not come with the Auto Darkening Lens** 

    This shell includes headband, front cover lens, airduct and face seal

    The Optrel Crystal 2.0 auto-darkening welding hood features a shade 2.0 light state unmatched for colour and clarity. The Crystal 2.0 lens has fully automatic shade 4 to 12 arc brightness detection with a Twilight feature to gradually bring the lens back into the light state from the welding state, reducing eye strain. Optrel's Autopilot automatically adjusts the shade level based on the brightness of the arc or flame. The auto-dark lens can also be operated in fully manual mode with infinite shade adjustment between shades 4 and 12 for a custom arc view. 

    The Crystal 2.0 welding helmet also has improved True Colour technology, which allows for realistic colour perception in light or dark states. It scores a perfect 1 rating for optical class, scattered light, homogeneity and angular dependence. The Crystal 2.0 has external controls to switch quickly and easily from weld to grind mode and back again. Delay and sensitivity can also be controlled using the external knobs.

    Does not include ADF Lens

    Optrel Crystal 2.0 with e3000 System Parts FAQs

    Spares for one maker's powered-air welding helmet and earlier-generation blower system: headbands, fixings, repair sets, filters and protective extras.

    How can I tell the headband is worn and needs replacing?icon-minus-redicon-plus-red

    A headband carries the helmet's weight and sets how it sits on your head, so wear shows up as comfort problems. Look for cracked or stretched plastic, a ratchet or adjuster that slips, worn or hard sweatband padding, and loose or damaged mounting points.

    A helmet that drops, tilts or will not hold its position can let the visor sit wrongly and spoil your view and your protection. Replace the headband with the part made for your helmet, and fit it as the manual shows. Sweatbands are often replaced separately, so you may not need a whole new headband.

    What are the small fixings and repair sets for?icon-minus-redicon-plus-red

    Helmets are held together by small parts such as bolts, quarter-turn fixings, pivots and clips, which can wear, crack or go missing with daily handling. A repair set usually groups the common wear items for one helmet type so a single fault does not take it out of use.

    Check the manual or parts list to see exactly what a set contains for your system. Replace threaded or turn fixings that are stripped or loose rather than forcing them, and use the correct ones, as the wrong size can damage the shell. Never use a helmet with a broken or missing fixing.

    What does an odour or carbon filter add to a particle filter?icon-minus-redicon-plus-red

    An odour filter, usually activated carbon, is fitted as an add-on to reduce smells and some irritants. It does not replace the particle filter, which is what catches fume and dust. HSE notes that gases such as ozone, especially from TIG welding of stainless steel and aluminium, and nitrogen oxides from arc welding can irritate the airways.

    Makers generally describe carbon add-ons as being for nuisance odours rather than a rated gas protection, so check the manual for what yours is intended for. If gases are a real concern on your jobs, your risk assessment decides what filtration you need. Do not wait for a smell to tell you a filter has failed.

    How do I choose the strength of a magnifying lens?icon-minus-redicon-plus-red

    A magnifying lens, sometimes called a cheater lens, fits inside the helmet for close or fine work. Its strength is in dioptres, and a higher number gives more magnification. Pick enough to see the weld clearly without straining your eyes, since too strong a lens can make your work harder to judge.

    If you wear glasses, discuss it with an optician as the lens works alongside your correction. Check the lens size and mounting suit your helmet and filter, keep it clean and replace it when scratched. Starting with a lower strength is usually the safer way to find what suits you.
