Failure to follow all safety guidelines prescribed in this document and by governing authorities and regulatory agencies may result in severe injury or death of personnel or machine damage.

Show/hide table

Personal injury or death can result from fumes, gases, and ultraviolet rays from the weld arc. Welding can cause fumes, burn skin, and produce ultraviolet rays. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both to keep fumes and gases from your breathing area. Wear eye, ear, and body protection before working. Protect yourself and others by reading and understanding this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death. Read and understand the instructions of the manufacturer and the safety practices of your employer. Do not touch live electrical parts.
