Operating Instructions

Important Safety Information (Continued)

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 compliant 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, flame resistant clothing, leather welding gloves, and full foot protection.

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 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 fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.

Take precautions to be sure that flying sparks and heat do not cause flames in hidden areas, cracks, behind bulkheads, etc.

Fire and explosion hazard!

Do not weld on containers or pipes

that contained flammable/combustible materials or gases.

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 your head 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 work 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 the 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.
