Damage to the lens of the eye can lead to arc-eye, which is an uncomfortable and often untreatable condition in that makes it feel as if there is sand in one's eye. Exposure to infrared radiation (IR) - IR is also created by the electric arc from welding and other metalworking equipment.
The arc temperature may be upto 20,000 K. Although TIG welding produces the highest quality welds, it is a slow and expensive process. Metal inert gas welding process (MIG) is economical with consumable electrode fed at a predetermined rate. Plasma arc welding (PAW) has made substantial progress in utilising the high heat energy of an ionised gas stream.
