General ventilation is usually sufficient to keep the fume well below allowable levels but it is usual to provide local extraction in manual operations where concentration of fume in the breathing zone may be higher.The majority of emissions in resistance welding are probably oil vapour or its breakdown products produced when welding oily steel.
