wire in the cable containing the circuit conductor or through a separate wire which is grounded at the source of the current. Grounding circuits, other than by means of a direct path, or a vessel's structure, should be checked to ensure that the circuit between the ground and the grounded power conductor has resistance low enough to permit sufficient current to flow to cause the fuse or circuit breaker to interrupt the current. • All ground connections must be inspected to ensure that they are mechanically strong and electrically adequate for the required current. Operating Instructions When electrode holders are to be left unattended, remove the electrodes and place the holders so that they cannot make electrical contact with employees or conducting objects. Do not dip hot electrode holders in water; this can expose the welder to electric shock. Turn off the power supply switch when stopping work for any appreciable length of time, or when the arc welding or cutting machine is to be moved. Inert -Gas Metal -Arc Welding The inert -gas metal -arc welding process involves the production of ultraviolet radiation of intensities of 5 to 30 times that produced during shielded metal -arc welding, the decomposition of chlorinated solvents by ultraviolet rays, and the liberation of toxic fumes and gases. Take the following special precautions: • Keep chlorinated solvents at least two hundred (2001 feet from the exposed arc. • Helpers and other employees in the area not protected from the arc by screening should be protected by filter lenses meeting the requirements. • Welders and other employees who are exposed to radiation should completely cover their skin to prevent bums and other damage by ultraviolet rays. Welding helmets and hand shields should be free of leaks and openings, and free of highly reflective surfaces. • When inert -gas metal -arc welding is being performed on stainless steel, provide mechanical ventilation and respiratory protection to protect against dangerous concentrations of nitrogen dioxide and chromium. PERSONAL PROTECTIVE EQUIPMENT (PPE) Personal protective equipment (PPE) must be worn as needed to protectfrom workplace hazards. Applicable equipment includes: • Work boots • Welding goggles and masks • Eye protection • Face -shields • Respirators • Hearing protection • Harnesses and lanyards • Leather welding gear • Gloves • Hard-hats A certification of hazard assessment is attached. Only PPE that fits properly will afford necessary
