Resumen del manual
Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting. To reduce magnetic fields in the workplace: • Keep cables close together by twisting or taping them. • Arrange cables to one side and away from you. • Do not coil or drape cables around your body. • Keep cutting power source and cables as far away from you as practical. • Connect work clamp to workpiece as close to the cut as possible. About Pacemakers: Pacemaker wearers consult your doctor first. If cleared by your doctor, then following the above procedures is recommended. FLASH HAZARDS WARNING ARC RAYS CAN INJURE EYES AND BURN SKIN! To reduce risk of injury from arc rays, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this cutting equipment, or is a bystander in the cutting area, understands and follows these safety instructions as well. • Do not look at an electric arc without proper protection. A cutting arc is extremely bright and intense and, with inadequate or no eye protection, the retina can be burned, leaving a permanent dark spot in the field of vision. A shield or helmet with a number 8-shade filter lens (minimum) must be used. • Do not strike a cutting arc until all bystanders and you (the welder) have welding shields and/or helmets in place. • Do not wear a cracked or broken helmet and replace any cracked or broken filter lenses IMMEDIATELY. • Provide bystanders with shields or helmets fitted with a number 8-shade filter lens. • Wear protective clothing. The intense light of the cutting arc can burn the skin in much the same way as the sun, even through lightweight clothing. Wear dark clothing of heavy material. The shirt worn should be long sleeved and the collar kept buttoned to protect chest and neck. • Protect against REFLECTED ARC RAYS. Arc rays can be reflected off shiny surfaces such as a glossy painted surface, aluminum, stainless steel, and glass. It is possible for your eyes to be injured by reflected arc rays even when wearing a protective helmet or shield. If cutting with a reflective surface behind you, arc rays can bounce off the surface, then off the filter lens on the inside of your helmet or shield, then into your eyes. If a reflective background exists in your cutting area, either remove it or cover it with something nonflammable and non- reflective. Reflected arc rays can also cause skin burn in addition to eye injury. FIRE HAZARDS WARNING FIRE OR EXPLOSION CAN CAUSE DEATH, INJURY, AND PROPERTY DAMAGE! To reduce risk of death, injury, or property damage from fire or explosion, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this cutting equipment, or is a bystander in the cutting area, understands and follows these safety instructions as well. REMEMBER! Plasma arc cutting by nature produces sparks, hot spatter, molten metal drops, hot slag, and hot metal parts that can start fires, burn skin, and damage eyes. • Do not wear gloves or other clothing that contain oil, grease, or other flammable substances. • Do not wear flammable hair preparations. • Do not cut in an area until it is checked and cleared of combustible and/or flammable materials. BE AWARE that sparks and slag can fly 35 feet and can pass through small cracks and openings. If work and combustibles cannot be separated by a minimum of 35 feet, protect against ignition with suitable, snug-fitting, fire resistant, covers or shields. • Do not cut on walls until checking for and removing combustibles touching the other side of the walls. • Do not weld, cut, or perform other such work on used barrels, drums, tanks, or other containers that had contained a flammable or toxic substance. The techniques for removing flammable substances and vapors, to make a used container safe for welding or cutting, are quite complex and require special education and training. • Do not strike an arc on a compressed gas or air cylinder or other pressure vessel. Doing so will create a brittle area that can result in a violent rupture immediately or at a later time as a result of rough handling. • Do not weld or cut in an area where the air may contain flammable dust (such as grain dust), gas, or liquid vapors (such as gasoline). • Do not handle hot metal, such as the workpiece or electrode stubs, with bare hands. • Wear leather gloves, heavy long sleeve shirt, cuffless trousers, high-topped shoes, helmet, and cap. As necessary, use additional protective clothing such as leather jacket or sleeves, fire resistant leggings, or apron. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and collars should be kept buttoned and pockets eliminated from the shirtfront. • Have fire-extinguishing equipment handy for immediate use! A portable chemical fire extinguisher, type ABC, is recommended. • Wear earplugs when cutting overhead to ...
