The employer shall ensure that each affected employee uses equipment with filter lenses that have a shade number that provides appropriate protection from injurious light radiation. Table I–1 is a listing of appropriate shade numbers for various operations. If filter lenses are used in goggles worn under a helmet which has a lens, the shade number of the lens in the helmet may be reduced so that the shade numbers of the two lenses will equal the value as shown in Table I–1, §1915.153.
|Operations||Electrode size 1/32 in.||Arc current||Minimum* protective shade|
|Shielded metal arc welding||Less than 3||Less than 60||7|
|More than 8||250-550||11|
|Gas metal arc welding and flux cored arc welding||Less than 60||7|
|Gas Tungsten arc welding||Less than 50||8|
|Air carbon||(Light)||Less than 500||10|
|Plasma arc welding||Less than 20||6|
|Plasma arc cutting||(light)**||Less than 300||8|
|Carbon Arc welding||14|
** These values apply where the actual arc is clearly seen. Lighter filters may be used when the arc is hidden by the workpiece.
|Operations||Plate thickness-inches||Plate thickness-mm||Minimum* protective shade|
|Light||Under ⅛||Under 3.2||4|
|Medium||⅛ to ½||3.2 to 12.7||5|
|Heavy||Over ½||Over 12.7||6|
|Light||Under 1||Under 25||3|
|Medium||1 to 6||25 to 150||4|
|Heavy||Over 6||Over 150||5|
* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line in the visible light of the (spectrum) operation.
