� Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays
of the arc can react with vapors to form highly toxic and irritating gases.
� Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the
coating is removed from the weld area, the area is well ventilated, and while wearing an air-
supplied respirator. The coatings and any metals containing these elements can give off toxic
fumes if welded.

*Start with a shade that is too dark to see the weld zone. Then, go to a lighter shade which gives
a sufficient view of the weld zone without going below the minimum.
