. Never use an electric arc welder to thaw frozen pipes. Flying sparks and hot metal can cause injury. As welds cool, slag can be thrown off. Take all precautions described in this manual to reduce the possibility of injury from flying sparks and hot metal. . Wear ANSI approved face shield or safety glasses with side shield protection when chipping or grinding metal parts. . Wear ear plugs when welding overhead to prevent spatter or slag from falling into ears. Electric arc welding operations produce intense light and heat and ultraviolet (UV) rays. This intense light and UV rays can cause injury to eyes and skin. Take all precautions described in this manual to reduce the possibility of injury to eyes and skin. . All persons operating this equipment or in the area while equipment is in use, must wear protective welding gear including: welding helmet or shield with at least shade 10 lens, flame resistant clothing, leather welding gloves and full foot protection. The welding wire is live whenever the welder is turned on - whether the trigger is pulled or not. Never look at arc welding operations without eye protection as described above. Never use a shade filter lens that is cracked, broken, or rated below number 10. Warn others in the area not to look at the arc. Electric arc welding operations cause sparks and heat metal to temperatures that can cause severe burns! Use protective gloves and clothing when performing any metal working operation. Take all precautions described in this manual to reduce the possibility of skin and clothing burns. . Make sure all persons in welding area are protected from heat, sparks and ultraviolet rays. Use additional face shields and flame resistant barriers as needed. . Never touch work pieces until completely cooled. Heat and sparks produced during electric arc welding and other metal working operations can ignite flammable and explosive materials! Take all precautions described in this manual to reduce the possibility of flames and explosions. . Remove all flammable materials within 35 feet (10.7 meters) of welding arc. If removal is not possible, tightly cover flammable materials with fire proof covers. Do not operate any electric arc 2 Model WG2020 General Safety (Continued) welder in areas where flammable or explosive vapors may be present. . Take precautions to ensure flying sparks and heat do not cause flames in hidden areas, cracks, etc. Fire hazard! Do not weld on containers or pipes that contain or have contained flammable materials or gaseous or liquid combustibles. Arc welding closed cylinders or containers such as tanks or drums can cause explosion if not properly vented! Verify that any cylinder or container to be welded has an adequate ventilation hole, so that expanding gases can be released. Do not breathe fumes produced by arc welding operation. These fumes are dangerous. If welding area cannot be adequately ventilated, be sure to use an air-supplied respirator. . Keep head and face out of welding fumes. . Extremely toxic fumes are created when galvanized or cadmium plated metals or metals which contain zinc, mercury or beryllium are heated. Complete the following precautions before performing electric arc welding operations on these metals: a. Remove coating from base metal. b. Make sure welding area is well ventilated. c. Use an air-supplied respirator. The electromagnetic field generated during arc welding may interfere with the operation of various electrical and electronic devices such as cardiac pacemakers. Persons using such devices should consult with their physician prior to performing any electric arc welding operations. . Route wire gun and work cables together and secure with tape when possible. . Never wrap arc welder cables around the body. . Always position wire gun and work leads on the same side of the body. . Exposure to electromagnetic fields during welding may have other health effects which are not known. Always be sure welding area is leaving. Be sure equipment is turned offsecure and free of hazards (sparks, flames, glowing metal or slag) prior tosure all metal and slag has cooled. are loosely coiled and out of the way. Be and excess wire is cut off. Be sure cables Cylinders can explode if damaged. 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, mechanical shocks and arcs. . Install and secure cylinders in an upright position by chaining them to stationary support or equipment cylinder rack to prevent falling or tipping. . Keep cylinders away from any welding or other electrical circuits. . Never allow a welding electrode to touch any cylinder. . Use only correct shielding gas cylinders, regulators, hoses and fittings designed for the specific application; maintain all parts properly. . Turn face away from valve out...
