Air Fed Welding Helmets

The fumes produced by welding and plasma cutting are a mixture of fine particles and toxic gases.For example,the majority of welding fume arises from the wire or rod electrode as it is vaporised for transfer over to the work piece.Some of the fume will be 'respirable' particles,which can be particularly damaging to lungs.As for the gases,these will include ozone,nitric oxide,nitrogen dioxide and carbon monoxide.Also if you are welding or cutting coated or oily surfaces,then additional products will become airborne.
