Arc Welding Hazards I A The symbols shown below are used throughout this manual to call attention to and identify possible hazards. When you seethe 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 NO TAG. Read and follow all Safety Standards. A Only qualified persons should install, operate, maintain, and repair this unit. A During operation, keep everybody, especially children, away. ELECTRIC SHOCK can kill. Touching live electrical parts can cause fatal shocks or severe bums. 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. Do not touch live electrical parts. Wear dry, hole-free insulating gloves and body protection. Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact. with the work or ground. Do not use AC output in damp areas, if movement is confined, or if there is a danger of falling. Use AC output ONLY if required for the welding process. If AC output is required, use remote output control if present on unit. Disconnect input power or stop engine before installing or servicing this equipment. Lockout/tagout input power according to OSHA 29 CFR 191 0.147 (see Safety Standards). Properly install and ground this equipment according to its Owners Manual and national, state, and local codes. Always verify the supply ground 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. When making input connections, attach proper grounding conductor first connections. Frequently inspect input power cord for damage or bare wiring replace cord immediately if damaged wiring can kill. Turn off all equipment when not in use. Do not use worn, damaged, undersized, or poorly spliced cables. Do not drape cables over your body. If earth grounding of the workpiece is required, ground it directly with a separate cable not use work clamp or work cable. Do not touch electrode if you are in contact with the work, ground, or another electrode from a different machine. Use onlywell-maintained equipment. Repairor replace damaged parts at once. Maintain unit according to manual. Wear a safety harness if working above floor level. Keep all panels and covers securely in place. Clamp work cable with good metal-to-metal contact to workpiece or worktable as near the weld as practical. Insulate work clamp when not connected to workpiece to prevent contact with any metal object. Do not connect more than one electrode or work cable to any single weld output terminal. SIGNIFICANT DC VOLTAGE exists after removal of input power on inverters. Tum Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before touching any parts. FUMES AND GASES can be hazardous. Welding produces fumes and gases. Breathing =9. these fumes and gases can be hazardous to your health. Keep your head out of the fumes. Do not breathe the fumes. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases. If ventilation is poor, use an approved air-supplied respirator. Read the Material Safety Data Sheets (MSDS5) and the manufacturers instructions for metals, consumables, coatings, cleaners, and degreasers. Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe. 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. 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 if necessary, while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded. OM-2211 Page 1
explosion ARC RAYS can burn eyes and skin BUILDUP OF GAS can Injure or kill Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can bum eyes and skin. Sparks fly oft from the weld. Weara welding helmet fitted with a proper shade of filterto protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). Wear approved safety glasses with side shields under your helmet. Use protective screens or barners to protect others from flash and glare; wam others not to watch the arc. Wear protective clothing made from durable, flame-resistant matenal (leather and wool) and foot protection. WELDING can cause fire or explosion. Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can fly oft 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, orfire. Check and be sure the area is safe before doing any welding. Protect yourself and others from flying sparks and hot metal. Do not weld where flying sparks can strike flammable material. Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers. Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Watch for fire, and keep a fire extinguisher nearby. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side. Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared according to AWS F4.1 (see Safety Standards). 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 and fire hazards. Do not use welder to thaw frozen pipes. Remove stick electrode from holder or cut off welding wire at contact tip when not in use. Wear oil-free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. Remove any combustibles, such as a butane lighter or matches, from your person before doing any welding. FLYING METAL can injure eyes. Welding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they can throw oft slag. Wear approved safety glasses with side shields even under your welding helmet. Shutoff shielding gas supply when not in use. Always ventilate confined spaces or use approved air-supplied respirator. HOT PARTS can cause severe burns.: Do not touch hot parts bare handed. Allow cooling period before working on gun or torch. MAGNETIC FIELDS can affect pacemakers. Pacemaker wearers keep away. Wearers should consult their doctor before going near arc welding, gouging, or spot welding operations. NOISE can damage hearing. Noise from some processes or equipment can damage hearing. Wear approved ear protection if noise level is high. Shielding 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. Protect compressed gas cylinders from excessive heat,... S S mechanical shocks, slag, open flames, sparks, and arcs. Install cylinders in an upright position by secunng to a stationary support or cylinder rack to prevent falling or tipping. Keep cylinders away from any welding or other electrical circuits. Never drape a welding torch over a gas cylinder. Never allow a welding electrode to touch any cylinder. Never weld on a pressurized cylinder will result. Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and associated parts in good condition. Turn face away from valve outlet when opening cylinder valve. Keep protective cap in place overvalve except when cylinder is in use or connected for use. Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-i listed in Safety Standards. CYLINDERS can explode if damaged. OM-2211 Page 2
I be 1-3 Additional Symbols for Installation, Operation, and Maintenance I FIRE OR EXPLOSION hazard~ MOVING PARTS can cause injury. Do not install or place unit on, over, or near combustible surfaces. Do not install unit near flammables. Do not overload building winng sure power supply system is properly sized, rated, and protected to handle this unit. Keep away from moving parts such as fans. Keep all doors, panels, covers, and guards closed and securely in place. FALLING UNIT can cause injury. Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories. Use equipment of adequate capacity to lift and support unit. If using lift forks to move unit, be sure forks are long enough to extend beyond opposite side of unit. OVERUSE can cause OVERHEATING Allow cooling period; follow rated duty cycle. Reduce current or reduce duty cycle before starting to weld again. Do not block or filter airflow to unit. HF. RADIATION can cause interference. High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment. Have only qualified persons familiar with electronic equipment perform this installation. The user is responsible for having a qualified electrician promptly correct any interference problem resulting from the installation. If notified by the FCC about interference, stop using the equipment at once. Have the installation regularly checked and maintained. Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and shielding to minimize the possibility of interference. STATIC (ESD) can damage PC boards. Put on grounded wrist strap BEFORE handling boards or parts. Use proper static-proof bags and boxes to store, move, or ship PC boards. MOVING PARTS can cause injury. Keep away from moving parts. Keep away from pinch points such as drive rolls. WELDING WIRE can cause injury Do not press gun trigger until instructed to do so. Do not point gun toward any part of the body, other people, or any metal when threading welding wire. ARC WELDING can cause interference. Electromagnetic energy can interfere with sensitive electronic equipment such as computers and computer-driven equipment such as robots. Be sure all equipment in the welding area is electromagnetically compatible. To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor. Locate welding operation 100 meters from any sensitive elec tronic equipment. Be sure this welding machine is installed and grounded according to this manual. If interference still occurs, the user must take extra measures such as moving the welding machine, using shielded cables, using line filters, or shielding the work area. 1-4.

If the unit is oper ated in the 750 ampere range, the unit is rated at 100% duty cycle. This means the polyweld system can be operated at 750 amperes X DUTY CYCLE continuously. When the unit is op erated in the 1500 ampere range, it is rated at 25% duty cycle. Main Transformer Duty Cycle at 750 Amperes The sum of the outputs of each module should not exceed the rated duty cycle of the main trans former. For example, the polyweld Main Transformer Continuous Welding Duty Cycle at 1500 Amperes system can be safely operated at a load of 1000 amperes at 80 per cent duty cycle. This value could be obtained by operating four mod ules at a load of 250 amperes at 80 percent duty cycle, or by operating six modules at a load of 167 amperes at 80 percent duty cycle. 2-1/2 Minutes Welding 7-1/2 Minutes Resting Single Module Duty Cycle at 250 Amperes 6 Minutes Welding 4 Minutes Resting Overheating Minutes OM-2211 Page 10
