●Make sure that all persons in the 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 welder in areas where flammable or explosive vapors may be present.
Take precautions to be sure that flying sparks and heat do not cause flames in hidden areas, cracks, behind bulkheads, etc.
!WARNING Firehazard! 
Do not weld on containers or
pipes that contain or have contained flammable materials or gaseous or liquid combustibles.
!WARNING Arcwelding 
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

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
●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
Extremely toxic fumes are created when these metals are heated.
!WARNING Theelectro-
magnetic 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 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.

Installation
LOCATION
Selecting the proper location can significantly increase performance, reliability and life of the arc welder.
●For best results locate the welder in an environment that is clean and dry. Avoid locations exposed to high temperature, high humidity, dust and corrosive fumes. 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 and filler metal in a clean, dry location with low humidity.
●The welder control panel contains information regarding proper input
