The electrode and work circuits are electrically live whenever the output is on. The power line and internal circuits of this equipment are also live when the line disconnect switch is on. When arc welding all metal components in the torch and work circuits are electrically live. Leaving piled-up dust in the welding machine may cause insulation deterioration and result in electrical shock and fire. 1. Do not touch live electrical parts. 2. Wear dry insulating gloves and other body protection that are free of holes. 3. Insulate yourself from work and ground using dry insulating mats or covers. 4. Be sure to disconnect the line disconnect switch before installing, changing torch parts or maintaining this equipment. 5. Properly install and ground this equipment according to its Owner’s Manual and national, state, and local codes. 6. Keep all panels and covers of this equipment securely in place. 7. Do not use worn, damaged, undersized, or poorly spliced cables. 8. Do not touch electrodes or any metal object if POWER switch is ON. 9. Do not wrap cables around your body. 10. Turn off POWER switch when not in use. 11. Remove dust by blowing moisture-free compressed air on each part periodically. ARC RAYS can burn eyes and skin: FLYING SPARKS AND HOT METAL can cause injury. NOISE can damage hearing. Arc rays from the welding process produce intense heat and strong ultraviolet rays that can burn eyes and skin. Noise from some arc welding can damage hearing. 1. Wear face shield with a proper shade of filter (See ANSI Z 49.1 listed in PRINCIPAL SAFETY STANDARDS) to protect your face and eyes when welding or watching a welder work. 2. Wear approved face shield or safety goggles. Side shields recommended. 3. Use protective screens or barriers to protect others from flash and glare: warn others not to look at the arc. 4. Wear protective clothing made from durable, flame-resistant material (wool and leather) and foot protection. 5. Use approved earplugs or earmuffs if noise level is high. Chipping and grinding can cause flying metal. As welds cool, they can throw off slag. 6. Wear proper body protection to protect skin. ―3― 2. ARC WELDING SAFETY PRECAUTIONS (continued) WELDING can cause fire and explosion. Sparks and spatter fly off from the welding arc. The flying sparks, hot metal, spatter, hot base metal and hot equipment can cause fire and explosion. Accidental contact of electrode or welding wire to metal object can cause sparks, overheating, or fire. Leaving piled-up dust in the welding machine may cause insulation deterioration and result in electrical shock and fire. 1. Protect yourself and others from flying sparks and hot metals. 2. Do not weld where flying sparks can strike flammable material. 3. Remove all flammables within 10m (33ft) of the welding arc. If this is not possible, tightly, cover them with approved covers. 4. Be alert that welding sparks and hot metals from welding can easily pass through cracks and openings into adjacent areas. 5. Watch for fire, and keep a fire extinguisher nearby. 6. Be aware that welding on a ceiling, floor, bulkhead, or partition can ignite a hidden fire. 7. Do not weld on closed containers such as tanks or drums. 8. Connect power cable for base metal as close to the welding area as possible to prevent the welding current from traveling along unknown paths and causing electric shock and fire hazards. 9. Remove stick electrode from holder or cut off welding wire at contact tip when not in use. 10. Do not use the welding power source for anything other than arc welding. 11. Wear oil-free protective garments such as leather gloves, a heavy shirt, cuffless trousers, boots, and a cap. 12. A loose cable connection can cause sparks and excessive heating. 13. Tighten all cable connections. 14. When there is an electrical connection between a work piece and the frame of wire feeder or the wire reel stand, arc may be generated and cause damage by a fire if the wire contacts the frame or the work piece. 15. Remove dust by blowing moisture-free compressed air on each part periodically. FUMES AND GASES can be hazardous to your health. Arc welding produce fumes and gases. Breathing these fumes and gases can be hazardous to your health. 1. Keep your head out of the fumes. Do not breathe the fumes. 2. Ventilate the area and/or use exhaust at the arc to remove welding fumes and gases. 3. If ventilation is poor, use an approved air-supplied respirator. 4. Read the Material Safety Data Sheets (MSDS) and the manufacturer’s instructions on metals, consumables, coatings, and cleaners. 5. Do not weld or cut in locations near degreasing, cleaning, or spraying operations. The heat and arc rays can react with vapors to form highly toxic and irritating gases. 6. Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Shielding gases used for welding can displace air causing injury or death. Be sure the breathing air is safe. ―4― 2. ARC WELDING SAFETY PRECAUTIONS (continued) CYLINDER can explode if damaged. A shielding gas cylinder contains high-pressure gas. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to handle them carefully. 1. Use only correct shielding gas cylinders, gas regulator, hoses, and fittings designed for the specific application; maintain them in good condition. 2. Protect compressed gas cylinders from excessive heat, mechanical shock, and arcs. 3. Keep the cylinder upright and securely chained to a stationary support or a rack to prevent falling or tipping. 4. Keep cylinders away from any welding or other electrical circuit. 5. Never touch cylinder with welding electrode. 6. Read and follow instructions on compressed gas cylinders, associated equipment, and the CGA publication P-1 listed in PRINCIPAL SAFETY STANDARDS. 7. Turn face away from valve outlet when opening cylinder valve. 8. Keep protective cap in place over valve except when gas cylinder is in use or connected for use. 9. Do not disassemble or repair the gas regulator except if you are authorized by the manufacturer. Rotating parts may cause injuries. Be sure to observe the following. If hands, fingers, hair or clothes are put near the fan’s rotating parts or wire feeder’s feed roll, injuries may occur. 1. Do not use this equipment if the case and the cover are removed. 2. When the case is removed for maintenance/inspection and repair, certified or experienced operators must perform the work. Erect a fence, etc. around this equipment to keep others away from it. 3.
