Shielded Metal






Arc Welder










Call Us First!


































































































This line of Campbell Hausfeld Arc





















Welders is designed to be used on











standard 115V household current. These










welders are equipped with infinite















amperage control to accurately select the










proper current needed for various










welding conditions. Internal components











are thermostatically protected.











This welder can weld up to 1/8” steel in











a single pass. Recommended electrode










size is 1/16” diameter for 15 amp




















circuits, up to 5/64” diameter for 20




















amp circuits. For replacement











electrodes, call (800) 746-5641 for the




















nearest dealer.










































When unpacking, inspect carefully for















any damage that may have occurred

Shielded Metal Arc Welder

General Safety (Con’t)

Always keep a fire extinguisher accessible while performing arc welding operations.

Before starting or servicing any electric arc welder, read and understand all instructions. Failure to follow safety precautions or instructions can cause equipment damage and or serious personal injury or death.

All installation, maintenance, repair and operation of this equipment should be performed by qualified persons only in accordance with national, state, and local codes.

Improper use of electric arc welders can cause electric shock, injury, and death! Take all precautions described in

this manual to reduce the possibility of electric shock.

Verify that all components of the arc welder are clean and in good condition prior to operating the welder. Be sure that the insulation on all cables, electrode holders, and power cords is not damaged. Always repair or replace damaged components before operating the welder. Always keep welder panels, shields, etc. in place when operating the welder.

Always wear dry protective clothing and welding gloves, and insulated footwear.

Always operate the welder in a clean, dry, well ventilated area. Do not operate the welder in humid, wet, rainy, or poorly ventilated areas.

Be sure that the work piece is properly supported and grounded prior to beginning any electric arc welding operation.

Coiled welding cable should be spread out before use to avoid overheating and damage to insulation.

Never immerse the electrode or

electrode holder in water. If the welder becomes wet for any reason, be absolutely certain that it is completely clean and dry prior to attempting use!

Always shut the equipment off and unplug the power prior to moving the unit.

Always attach the work lead first.

Verify that the work piece is securely grounded.

Always shut off electric arc welding equipment when not in use and, and remove the electrode from the holder.

Never allow any part of the body to touch the electrode and ground or grounded work piece at the same time.

Awkward welding conditions and positions can be electrically hazardous. When crouching, kneeling or at elevations, be sure to insulate all conductive parts, wear appropriate protective clothing, and take precautions to prevent injury from falls.

Never attempt to use this equipment at current settings or duty cycles higher than those specified on the equipment labels.

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, 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 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.


Models WS0900, WS0950, WS1000 and WS1020

General Safety (Con’t)

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

Refer to the Material Safety Data Sheets and the manufacturers instructions for metals, electrodes, coatings and cleaners.



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. Dust and dirt in the welder retain moisture and increase wear of moving parts.

Store electrodes in a clean, dry location with low humidity to preserve the flux coating.

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 on page 1 for correct circuit capacity.

The use of an extension cord is not recommended for arc welding machines. Extension cord use will significantly degrade the performance of the welder.
