Consult symbols and related instructions below for necessary actions to avoid the hazards. . 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. . When making input connections, attach proper grounding conductor first . double-check connections. . Keep cords dry, free of oil and grease, and protected from hot metal and sparks. . Frequently inspect input power cord for damage or bare wiring . replace cord immediately if damaged . bare 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. . Do not touch electrode if you are in contact with the work, ground, or another electrode from a different machine. . Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be present. . Use only well-maintained equipment. Repair or 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 in inverter-type welding power sources after removal of input power. . Turn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before touching any parts. HOT PARTS can cause severe burns. . Do not touch hot parts bare handed. . Allow cooling period before working on gun or torch. . To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. OM-222 Page 1 FUMES AND GASES can be hazardous. Welding produces fumes and gases. Breathing 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 local forced ventilation at the arc to remove welding fumes and gases. . If ventilation is poor, wear an approved air-supplied respirator. . Read and understand the Material Safety Data Sheets (MSDSs) and the manufacturer’s 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 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. . 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 while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded. ARC RAYS can burn eyes and skin. 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. . Wear an approved welding helmet fitted with a proper shade of filter lenses to 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 barriers to protect others from flash, glare and sparks; warn others not to watch the arc. . Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton, or 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 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. . Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers. . Do not weld where flying sparks can strike flammable material. . Protect yourself and others from flying sparks and hot metal. . 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, flo...
