whats the proper way to view while TIG'ing. better to go dark and close up, or further away while lighter on the shade? i find myself being real close to the arc with a darker shade, but i dont think is good for my eyes as the UV is very intense at that distance. but then again, if i view from a further distance i find myself having a harder time watching the pool and flow, especially while welding around circles in the vertical plane.
any advice??
