- Gh0stRAT 4y ago>Does this process really produce no UV? I have no idea, but the microscope he's looking through could certainly have UV protection built-in. Or perhaps the pulses are so short and small that the cumulative risk is negligible? Either way, it seems to me like there could be ways for it to be safe enough to require minimal PPE while still producing some non-zero amount of UV.
- analog31 4y agoI'm also thinking about skin exposure. Fortunately glass optics are at least opaque to the most dangerous bands of UV, but not to retinal blue, which has its own special place in the regulations.
- gaze 4y agothe microscope blanks when the arc is fired
- MaxikCZ 4y agoWhat happens if one time it fails? Does it instant blind?
- monknomo 4y agoLooking straight into a welding arc doesn't blind you instantly. Eventually, sure. More rapidly it gives you a lingering after image and feeling like your eyeball is full of sand
- convolvatron 4y agothe 'eyeball full of sand' can last for several days, and really interfere with your normal functioning. that and the greatly increased acceleration of cataract development means really dont look at the blue light.
- monknomo 4y agooh yes, I can see where my comment might sound like I'm saying it's ok to look at the arc; it's not. It's just that it won't blind you right away
- michaelt 4y agoAuto-darkening welding masks block UV and IR all the time [1] so you're protected against things like arc-eye even if it fails to darken. Also, masks generally fail-safe (to darkened, e.g. for flat batteries) and presumably this welding microscope is designed to the same standard.
