Welding Arc Eye Distance. There is no clearly defined limit since the distance depends upon the exposure time welding process welding current and other environmental conditions. The inverse square law is your friend in this case.
Arc welding is a manual skill requiring a steady hand good physical condition and good eyesight. The US Army have carried out trials which propose distances of between 3 and 20 metres for an exposure time of 10 minutes for MMA SMA. Safety glasses with UV protection are the unsung hero of welding accessories.
There is no clearly defined limit since the distance depends upon the exposure time welding process welding current and other environmental conditions.
There is no clearly defined limit since the distance depends upon the exposure time welding process welding current and other environmental conditions. The amount of time required to cause these effects depends on several factors such as the intensity of the radiation the distance from the welding arc the angle at which the radiation enters the eye and type of eye protection that the welder or bystander is using. Therefore if you are a short distance from an arc even a very short exposure to the arc flash can result in injury. Your cornea can repair itself in.
