CHAPTER 4 WELDER/GENERATOR Section 1 - Safety Rules for Operation of Arc Welding Power Source 4-1 INTRODUCTION 4-1.1 We learn by experience. Learning safety through personal experience, like a child touching a hot stove is harmful, wasteful, and unwise. Let the experience of others teach you. 4-1.2 Safe practices developed from experience in the use of welding and cutting are described in this manual. Research, development, and field experience have evolved reliable equipment and safe installation, operation, and servicing practices. Accidents occur when equipment is improperly used or maintained. The reason for the safe practices may not always be given. Some are based on common sense, others may require technical volumes to explain. It is wiser to follow the rules. 4-1.3 Read and understand these safe practices before attempting to install, operate, or service the equipment. Comply with these procedures as applicable to the particular equipment used and their instruction manuals, for personal safety and for the safety of others. 4-1.4 Failure to observe these safe practices may cause serious injury or death. When safety becomes a habit, the equipment can be used with confidence. 4-1.5 Reference standards: Published Standards on safety are also available for additional and more complete procedures than those given in this manual. They are listed in paragraph 4-4. ANSI Z49.1 is the most complete. 4-1.6 The National Electrical Code, Occupational Safety and Health Administration, local industrial codes, and local inspection requirements also provide a basis for equipment installation, use, and service. 4-2 GENERAL PRECAUTIONS NOTE Different arc welding processes, electrode alloys, and fluxes can produce different fumes, gases, and radiation levels. In addition to the information in this manual, be sure to consult flux and electrode manufacturers for specific technical data and precautionary measures concerning their material. 4-2.1 Burn Prevention a. Wear protective clothing - gauntlet gloves designed for use in welding, hat, and high safety-toe shoes. Button shirt collar and pocket flaps, and wear cuffless trousers to avoid entry of sparks and slag. b. Wear helmet with safety goggles or glasses with side shields underneath, appropriate filter lenses or plates (protected by clear cover glass). This is a MUST 4-1
