A welding hand shield is a metal plate containing the same protective lens as a welding helmet with a handle on the bottom, intended to be held up in front ...
However, any molten material that splatters onto synthetic material will melt directly through the fabric resulting in severe burns. [84] Arc welding produces intense visible and ultraviolet light. Typical gas metal arc welding has an irradiance of 5W/m 2 for the welder, which is many times brighter than sunlight. [85]
Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...

Additionally, the brightness of the weld area can lead to a condition called arc eye or flash burn, in which ultraviolet light causes inflammation of the cornea and can burn the retinas of the eyes. Welding helmets with dark face plates are worn to prevent this exposure, and in recent years, new helmet models have been produced that feature a ...
