    Welding eye protection

    Am I right in thinking that the most damaging light from welding is the invisible UV light which is mostly filtered out by the clear lens in a welding helmet, the dark lens protecting you from the dazzling effect of the visible light which isn't so dangerous?

    Just bought an auto-darkening helmet but worried what might happen if the batteries run flat

    Test it before using it! Just looking at a light bulb should darken it.

    You bought one with batteries???
    Why did you not get a solar powered one? Kind of sorts itself out when the welding starts. i.e. Bright light= charged battery.

    It has a solar cell on the front too - perhaps the batteries are just a backup?

    If you look through the mask without it being dimmed it should not be perfectly clear. My mask is a solar powered one and it is still quite dark to look through, but clear enough to see what you need. It gets a lot darker once you look at a strip light, The sun or strike an ark with the welder.

    I think it would be brighter if the batteries failed but not bright enough to damage your eyes.

    UV

    You're correct in saying that the glass stops uv rays. You wont get a suntan in a conservatory. However the degree of darkness stops the glare which, on its own, can be quite damaging to the retina.
    The brightest arc is when TIG welding so consequently the glass needs to be darker than if MIG welding & aluminium welding gives off an intense light as well.
    If it's arc eye you're worried about that shouldn't be an issue even if the auto-dimming fails as the clear lens will protect you. It is rare that these masks fail though.

    Thank you everyone, apart from Andy
    I had suspected that was the case. As Craig said, the mask is fairly dark before it activates so I won't need to wear sunglasses underneath...

    It's a stick welder, in case anyone is interested - I have it on long-term loan and am intending to use it on the Landrover only
