Consult symbols and related instructions below for necessary actions to avoid the hazards. 1-2. Arc Welding Hazards The symbols shown below are used throughout this manual to call attention to and identify possible hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards. Only qualified persons should install, operate, maintain, and repair this unit. During operation, keep everybody, especially children, away. Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard. D Do not touch live electrical parts. ELECTRIC SHOCK can kill. D Wear dry, hole-free insulating gloves and body protection. D Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. D Do not use AC output in damp areas, if movement is confined, or if there is a danger of falling. D Use AC output ONLY if required for the welding process. D If AC output is required, use remote output control if present on unit. D Additional safety precautions are required when any of the following electrically hazardous conditions are present: in damp locations or while wearing wet clothing; on metal structures such as floors, gratings, or scaffolds; when in cramped positions such as sitting, kneeling, or lying; or when there is a high risk of unavoid- able or accidental contact with the workpiece or ground. For these conditions, use the following equipment in order presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual (stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder is recommended. And, do not work alone! D Disconnect input power or stop engine before installing or servicing this equipment. Lockout/tagout input power according to OSHA 29 CFR 1910.147 (see Safety Standards). D Properly install, ground, and operate this equipment according to its Owner’s Manual and national, state, and local codes. D Always verify the supply ground − check and be sure that input power cord ground wire is properly connected to ground terminal in disconnect box or that cord plug is connected to a properly grounded receptacle outlet. D When making input connections, attach proper grounding conductor first − double-check connections. D Keep cords dry, free of oil and grease, and protected from hot metal and sparks. D Frequently inspect input power cord and ground conductor for damage or bare wiring – replace immediately if damaged – bare wiring can kill. D Turn off all equipment when not in use. D Do not use worn, damaged, undersized, or repaired cables. D Do not drape cables over your body. D If earth grounding of the workpiece is required, ground it directly with a separate cable. D Do not touch electrode if you are in contact with the work, ground, or another electrode from a different machine. D Do not touch electrode holders connected to two welding ma- chines at the same time since double open-circuit voltage will be present. D Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual. D Wear a safety harness if working above floor level. D Keep all panels and covers securely in place. D Clamp work cable with good metal-to-metal contact to workpiece or worktable as near the weld as practical. D Insulate work clamp when not connected to workpiece to prevent contact with any metal object. D Do not connect more than one electrode or work cable to any single weld output terminal. Disconnect cable for process not in use. D Use GFCI protection when operating auxiliary equipment in damp or wet locations. SIGNIFICANT DC VOLTAGE exists in inverter welding power sources AFTER removal of input power. D Turn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before touching any parts. HOT PARTS can burn. D Do not touch hot parts bare handed. D Allow cooling period before working on equipment. D To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. Downloaded from www.Manualslib.com manuals search engine

OM-316 Page 2 Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. FUMES AND GASES can be hazardous. D Keep your head out of the fumes. Do not breathe the fumes. D If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding fumes and gases. The recommended way to determine adequate ventilation is to sample for the composition and quantity of fumes and gases to which personnel are exposed. D If ventilation is poor, wear an approved air-supplied respirator. D Read and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals. D Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watch- person nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe. D Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases. D Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating is removed from the weld area, the area is well ventilated, and while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld. D Wear an approved welding helmet fitted with a proper shade of filter lenses to protect your face and eyes from arc rays and sparks when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). D Wear approved safety glasses with side shields under your helmet. D Use protective screens or barriers to protect others from flash, glare and sparks; warn others not to watch the arc. D Wear body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. ARC RAYS can burn eyes and skin. Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding. WELDING can cause fire or explosion. D Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers. D Do not weld where flying sparks can strike flammable material. D Protect yourself and others from flying sparks and hot metal. D Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. D Watch for fire, and keep a fire extinguisher nearby. D Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side. D Do not weld on containers that have held combustibles, or on closed containers such as tanks, drums, or pipes unless they are properly prepared according to AWS F4.1 and AWS A6.0 (see Safety Standards). D Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapors (such as gasoline). D Connect work cable to the work as close to the welding area as practical to prevent welding current from traveling long, possibly unknown paths and causing electric shock, sparks, and fire hazards. D Do not use welder to thaw frozen pipes. D Remove stick electrode from holder or cut off welding wire at contact tip when not in use. D Wear body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. D Remove any combustibles, such as a butane lighter or matches, from your person before doing any welding. D After completion of work, inspect area to ensure it is free of sparks, glowing embers, and flames. D Use only correct fuses or circuit breakers. Do not oversize or by- pass them. D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B for hot work and have a fire watcher and extinguisher nearby. D Read and understand the Safety Data Sheets (SDSs) and the manufacturer s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals. FLYING METAL or DIRT can injure eyes. D Welding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they can throw off slag. D Wear approved safety glasses with side shields even under your welding helmet. BUILDUP OF GAS can injure or kill. D Shut off compressed gas supply when not in use. D Always ventilate confined spaces or use approved air-supplied respirator. ELECTRIC AND MAGNETIC FIELDS (EMF) can affect Implanted Medical Devices. D Wearers of Pacemakers and other Implanted Medical Devices should keep away. D Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. Noise from some processes or equipment can damage hearing. D Wear approved ear protection if noise level is high. NOISE can damage hearing. Compressed gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully. CYLINDERS can explode if damaged. D Protect compressed gas cylinders from excessive heat, mechani- cal shocks, physical damage, slag, open flames, sparks, and arcs. D Install cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or tipping. D Keep cylinders away from any welding or other electrical circuits. D Never drape a welding torch over a gas cylinder. D Never allow a welding electrode to touch any cylinder. D Never weld on a pressurized cylinder − explosion will result. D Use only correct compressed gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and associated parts in good condition. D Turn face away from valve outlet when opening cylinder valve. Do not stand in front of or behind the regulator when opening the valve. D Keep protective cap in place over valve except when cylinder is in use or connected for use. D Use the right equipment, correct procedures, and sufficient number of persons to lift and move cylinders. D Read and follow instructions on compressed gas cylinders, associated equipment, and Compressed Gas Association (CGA) publication P-1 listed in Safety Standards.

EMF Information Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). The current from arc welding (and allied processes including spot welding, gouging, plasma arc cutting, and induction heating operations) creates an EMF field around the welding circuit. EMF fields may interfere with some medical implants, e.g. pacemakers. Protective measures for persons wearing medical implants have to be taken. For example, restrict access for passers−by or con- duct individual risk assessment for welders. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit: 1. Keep cables close together by twisting or taping them, or using a cable cover. 2. Do not place your body between welding cables. Arrange cables to one side and away from the operator. 3. Do not coil or drape cables around your body. 4. Keep head and trunk as far away from the equipment in the welding circuit as possible. 5. Connect work clamp to workpiece as close to the weld as possible. 6. Do not work next to, sit or lean on the welding power source. 7. Do not weld whilst carrying the welding power source or wire feeder. About Implanted Medical Devices: Implanted Medical Device wearers should consult their doctor and the device manufacturer before performing or going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. If cleared by your doctor, then following the above procedures is recommended. Downloaded from www.Manualslib.com manuals search engine
