question 6
the primary factor in selecting the correct shade lens for a helmet is:
a the welding process
b the amperage setting
c the amount of natural lighting
d all of these

Explanation:

The amperage setting affects the intensity of the arc - light during welding, which is crucial for lens shade selection. Different welding processes produce different light intensities and spectra, also influencing lens choice. Natural lighting can impact overall visibility and thus is a factor in choosing the right shade to balance between protection and visibility.
