SAFETY PRECAUTIONS

FUMES AND GASES -- Fumes and gases, can cause discomfort or harm, particularly in confined spaces. Do not breathe fumes and gases. Shield- ing gases can cause asphyxiation. Therefore:

1.Always provide adequate ventilation in the work area by natural or mechanical means. Do not weld, cut, or gouge on materials such as galvanized steel, stainless steel, copper, zinc, lead, beryllium, or cadmium unless posi- tive mechanical ventilation is provided. Do not breathe fumes from these materials.

2.Do not operate near degreasing and spraying opera- tions. The heat or arc rays can react with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas, and other irritant gases.

3.If you develop momentary eye, nose, or throat irritation while operating, this is an indication that ventilation is not adequate. Stop work and take necessary steps to im- prove ventilation in the work area. Do not continue to operate if physical discomfort persists.

4.Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation recommendations.

5.WARNING: This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code §25249.5 et seq.)

CYLINDER HANDLING -- Cylinders, if mishandled, can rupture and violently release gas. Sudden rupture of cylin- der, valve, or relief device can injure or kill. Therefore:

1.Use the proper gas for the process and use the proper pressure reducing regulator designed to operate from the compressed gas cylinder. Do not use adaptors. Maintain hoses and fittings in good condition. Follow manufacturer's operating instructions for mounting regu- lator to a compressed gas cylinder.

2.Always secure cylinders in an upright position by chain or strap to suitable hand trucks, undercarriages, benches, walls, post, or racks. Never secure cylinders to work tables or fixtures where they may become part of an electrical circuit.

3.When not in use, keep cylinder valves closed. Have valve protection cap in place if regulator is not con- nected. Secure and move cylinders by using suitable hand trucks. Avoid rough handling of cylinders.

4.Locate cylinders away from heat, sparks, and flames. Never strike an arc on a cylinder.

5.For additional information, refer to CGA Standard P-1, "Precautions for Safe Handling of Compressed Gases in Cylinders", which is available from Compressed Gas Association, 1235 Jefferson Davis Highway, Arlington, VA 22202.

EQUIPMENT MAINTENANCE -- Faulty or improperly maintained equipment can cause injury or death. Therefore:

1.Always have qualified personnel perform the installa- tion, troubleshooting, and maintenance work. Do not perform any electrical work unless you are qualified to perform such work.

2.Before performing any maintenance work inside a power source, disconnect the power source from the incoming electrical power.

3.Maintain cables, grounding wire, connections, power cord, and power supply in safe working order. Do not operate any equipment in faulty condition.

4.Do not abuse any equipment or accessories. Keep equipment away from heat sources such as furnaces, wet conditions such as water puddles, oil or grease, corrosive atmospheres and inclement weather.

5.Keep all safety devices and cabinet covers in position and in good repair.

6.Use equipment only for its intended purpose. Do not modify it in any manner.

ADDITIONAL SAFETY INFORMATION -- For more information on safe practices for elec- tric arc welding and cutting equipment, ask your supplier for a copy of "Precautions and Safe Practices for Arc Welding, Cutting and Gouging", Form 52-529.
