In welding, as in most jobs, exposure to certain hazards occurs. Welding is safe when precautions are taken. The
safety information given below is only a summary of the more complete safety information that will be found in the
Safety Standards listed on the next page. Read and follow all Safety Standards.

and all metal parts touching the welding wire are
electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
