*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.

1.6 Protective Clothing

Like other jobs or careers, welders must wear suitable protective equipment. In
general, Personal Protective Equipment (PPE) must protect against hazards
such as burns, sparks, spatter, electric shock, and radiation. The use of PPE is a
good safe practice and may be required by regulatory agencies.
