High humidity causes moisture condensation on electrical components. Moisture can contribute to corrosion and short electrical components. Dust and dirt in the welder retain moisture and increase wear of moving parts. Place the welder in an area that provides at least twelve inches (305 mm.) of ventilation space at both the front and rear of the unit. Keep all obstructions away from this ventilation space. Store electrodes in a clean, dry location with low humidity, such as WT2240 Electrode Container, to preserve the flux coating. The welder control panel contains information regarding proper input voltage and amperage. Follow the specifications on the welder front panel. The receptacle used for the welder must be properly grounded and the welder must be the only load on the power supply circuit. Refer to the Circuit Amps chart under Specifications for correct circuit capacity. The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in the extension cord may significantly degrade the performance of the welder. 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 that are produced by the arc welding operation. These fumes are dangerous. If the welding area cannot be adequately ventilated, be sure to use an air-supplied respirator. Keep the head and face out of the welding fumes. Do not perform electric arc welding operations on metals that are galvanized or cadmium plated, or contain zinc, mercury, or beryllium without completing the following precautions: a. Remove the coating from the base metal. b. Make sure that the welding area is well ventilated. c. Use an air-supplied respirator. Extremely toxic fumes are created when these metals are heated. The electromagnetic field that is 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 the electrode and work cables together and secure with tape when possible. Never wrap arc welder cables around the body. Always position the electrode and ground leads so that they are on ! WARNING ! WARNING ! WARNING ! WARNING Model WS2800 the same side of the body. Exposure to electromagnetic fields during welding may have other health effects which are not known. Always be sure that the welding area is secure and free of hazards (sparks, flames, glowing metal or slag) prior to leaving. Be sure that equipment is turned off and electrode is removed. Be sure that cables are loosely coiled and out of the way. Be sure that all metal and slag has cooled. • This product, when used for welding, produces fumes or gases which contain chemicals known to the State of California to cause birth defects (or other reproductive harm) and, in some cases, cancer (California Health & Safety Code Section 25249.5 et seq.). • To request Material Safety Data Sheet (MSDS), visit the Internet at or call 1-800-746-5641.
