GENERAL SAFETY PRECAUTIONS 1.

The following safety information is provided as a guideline to help you

operate your new welder under the safest possible conditions. Any

equipment that uses electrical power can be potentially dangerous to use

when safety or safe handling instructions are not known or not followed.

The following safety information is provided to give you the information

necessary for safe use and operation.

When a WARNING precedes a procedure step, it is an indication that the

step contains a procedure that might be injurious to a person if proper

safety precautions are not heeded. When a procedure step is preceded

by a CAUTION, it is an indication that the step contains a procedure that

might damage the equipment being used. A NOTE may be used before or

FUME HAZARDS 1.5

WARNING: FUMES, GASES, AND VAPORS CAN CAUSE

DISCOMFORT, ILLNESS, AND DEATH! To reduce risk of

discomfort, illness, or death, read, understand, and follow the

following safety instructions. In addition, make certain that anyone

else that uses this welding equipment or is a bystander in the

welding area, understands and follows these safety instructions as

well.

Do not weld in an area until it is checked for adequate ventilation as •

described in ANSI standard #Z49.1. If ventilation is not adequate to

exchange all fumes and gasses generated during the welding process

withfreshair,donotweldunlessyou(thewelder)andallbystandersare

wearing air-supplied respirators.

Do not heat metals coated with, or that contain, materials that produce •

toxicfumes(suchasgalvanizedsteel),unlessthecoatingisremoved.

Make certain the area is well ventilated, and the operator and all

bystanders are wearing air-supplied respirators.

Do not weld, cut, or heat lead, zinc, cadmium, mercury, beryllium, or •

similar metals without seeking professional advice and inspection of

the ventilation of the welding area. These metals produce EXTREMELY

TOXIC fumes that can cause discomfort, illness, and death.

Do not weld or cut in areas that are near chlorinated solvents. •

Vapors from chlorinated hydrocarbons, such as trichloroethylene and

perchloroethylene, can be decomposed by the heat of an electric arc or

its ultraviolet radiation. These actions can cause PHOSGENE, a HIGHLY

TOXIC gas to form, along with other lung and eye-irritating gases. Do not

weld or cut where these solvent vapors can be drawn into the work area

or where the ultraviolet radiation can penetrate to areas containing even

very small amounts of these vapors.

Donotweldinaconnedareaunlessitisbeingventilatedandthe•

operator(andanyoneelseinthearea)iswearinganair-supplied

respirator.

Stop welding immediately if you develop momentary eye, nose, or •

throat irritation as this indicates inadequate ventilation. Stop work and

take necessary steps to improve ventilation in the welding area. Do not

resume welding if physical discomfort persists.

POWER REQUIREMENTS 2.4

WARNING: THIS WELDING MACHINE MUST BE CONNECTED

TO A POWER SOURCE IN ACCORDANCE WITH APPLICABLE

ELECTRICAL CODES.

This welder intermittently draws more than 15 amps of current. We

recommend that you either install a 20 amp circuit or do not run anything

else on the same circuit as the welder or you may trip the breaker

supplying the AC power. If you modify the power cord in any way, other

than attaching the proper input plug, you will void the manufacturer’s

warranty.Itisrecommendedthataqualiedelectricianverifytheactual

voltageatthereceptacleintowhichthewelderwillbepluggedandconrm

that the receptacle is properly fused and grounded. The use of the proper

circuit size can eliminate nuisance circuit breaker tripping while welding.

DO NOT OPERATE THIS WELDER if the actual power source voltage is

lessthan100voltsACorgreaterthan125voltsAC.Contactaqualied

electrician if this problem exists. Improper performance, damage to the

welder, property damage and/or personal injury can result if operated on

inadequate or excessive power.

WARNING: ELECTRIC SHOCK CAN KILL! FIRE CAN KILL,

INJURE, AND CAUSE PROPERTY DAMAGE!

Toreducetheriskofelectricshockandre,connectonlyto •

properly grounded and fused outlets.

Never alter the AC power cord provided on the welder. Never •

alter an extension cord or extension cord plugs.

• 8 •

EXTENSION CORD USE 2.5

For optimum welder performance, an extension cord should not be used

unless absolutely necessary. If necessary, care must be taken in selecting

anextensioncordappropriateforusewithyourspecicwelder.

Select a properly grounded extension cord that will mate the AC power

cord of the welder with the AC power source receptacle directly, without

the use of adapters. Make sure the extension cord is properly wired and in

good electrical condition.

For an extension cord not exceeding 25 feet in length, choose the same

AWG wire size as that of the power cord on the welder. Extension cord

lengths longer than 25 feet will require heavier wire gauges to compensate

for voltage losses.

OPERATION 3.

GETTING TO KNOW YOUR NEW WELDER 3.1

Whether or not you have welded before, it is important that you become

familiar with your welder, its controls, and the results achieved at different

settings. We strongly recommend that you practice with your new welder

on scrap metal, trying a variety of heat settings, base metal thicknesses,

and welding positions for each type and size of wire that you will be

using. By doing this you will gain a feel for how changes in these welding

variables affect the weld.

If you have not welded before, you will need to develop welding skills and

techniques as well. The self-taught welder learns through a process of trial

and error. The best way to teach yourself how to weld is with short periods

of practice at regular intervals.

Do not attempt to weld on any valuable equipment until you have made

practice welds on scrap metal that can be discarded. The scrap metal

should be of the same type and thickness as that of the item to be welded.

Onlyafteryouaresatisedthatyourpracticeweldsareofgoodstrength

and appearance, should you attempt your actual

welding job.

CONTROLS & THEIR FUNCTIONS 3.2

AMPERAGE CONTROL

Two settings can be selected. The lower setting for

thinner material and smaller welding electrodes,

the higher setting for thicker materials and larger

welding electrodes.

• 10 •

ON-OFF – THERMAL INDICATOR

To turn the power on to the welder, push the main switch to ON. Your

welder has a lighted main switch. This light will come on if the welder has

overheated. The light indicates that a thermostat has shut off the power

within the welder. Once the welder has cooled, the thermostat will turn the

welder back on and the light will go out. Over heating is usually caused by

exceeding the welder duty cycle.

DUTY CYCLE

The duty cycle rating of a welder is a measure of how long the welder

can weld and how long it must be rested and cool. It is expressed as

apercentageoftenminutes(theindustryrecognizedcycletime)and

represents the maximum welding time allowed, with the balance of the ten

minute cycle required for cooling.

INTERNAL THERMAL PROTECTION

If you exceed the duty cycle of your welder, an internal thermal protector

will open and shut off all welder functions. If this ever happens to you,

do not shut off the welder! Leave it turned on. After cooling a while, the

thermal protector will automatically reset and the welder will function

again. However, you should wait at least 10 minutes after the thermal

protector opens before resuming welding, even if the protector resets

itselfsooner,oryoumayexperiencelessthanspecieddutycycle

performance.

CAUTION! DO NOT CONSTANTLY EXCEED THE DUTY CYCLE OR

DAMAGE TO THIS WELDER WILL RESULT!

CONNECT WELDER GROUND

Attach the ground clamp to the work piece making sure that the work

piece is cleaned of dirt, oil, rust, scale, oxidation, and paint at the point

of connection. It is best to connect the ground clamp directly to the work

piece and as close to the weld as possible. If it is impractical to connect

the ground clamp directly to the work piece, connect it to metal that is

securely attached to the work piece, but not electrically insulated from it.

Also, make sure this other metal is of similar or greater thickness than that

of the work piece.

CAUTION! RISK OF ELECTRONIC COMPONENT DAMAGE!

If the ground clamp is being connected to an automobile or other

equipment with on-board computer systems, solid state electronic

controls, solid state sound systems, etc., do not weld until disconnecting

the cable from the battery that is attached to chassis ground. Failure to do

so may result in electronic component damage!

GENERAL WELDING INFORMATION 4.

PREPARATIONS FOR WELDING 4.1

An important factor in making a satisfactory weld is preparation.

This includes studying the process and equipment and then practice

weldingbeforeattemptingtoweldnishedproduct.Anorganized,safe,

convenient, comfortable, well lighted work area should be available to the

operator.Theworkareashouldspecicallybefreeofallammableswith

bothareextinguisherandbucketofsandavailable.

To properly prepare for welding, it is necessary to:

Prepare an organized, well lighted work area 1.

Provide protection for the eyes and skin of the operator and 2.

bystanders.

Set up the work piece and make the ground clamp connection. 3.

Select the electrode. 4.

Turn the power switch on. 5.

SETTING UP THE WORK PIECE 4.2

Welding Positions

Arc welding can be performed in any of the four basic positions: Flat,

Horizontal, Vertical and Overhead. Flat welding is generally easier,

faster, and allows for better penetration. Overhead welding is the most

difcult.The(rod)selectionswillbeaffectedbythepositions.Verticaland

overhead welding are usually only attempted when using a welder with dc

welding capabilities.

If possible, the work piece should be positioned so that the bead will run

onaatsurface.

Preparing The Joint

For effective welding, the surfaces to be joined must be free of dirt, rust,

scale, oil or paint. Welding on metals not properly cleaned will cause a

brittle and porous weld.

If the base metal pieces to be joined are thick or heavy, it may be

necessary to bevel the edges, with a metal grinder, at the point of contact,

as shown below. The angle of the bevel should be approximately 60

degrees. If utilizing a grinder, be sure to follow all manufacturer warnings

and procedures.

See the chart below for detailed instructions for preparing the weld joint.

• 12 •

During the welding, the work pieces will become hot and will tend to

expand. The expansion may cause the pieces to shift from the regular

position. If possible, the work pieces should be clamped into the position

they are to occupy when the welding is completed.

Selecting The Proper Electrode 4.3

The welding electrode is a rod, or wire, of electrically conductive metal,

coatedwithalayerofux.

Whenwelding,electricalcurrentowsbetweentheelectrode(rod)andthe

grounded metal work piece. The intense heat of the arc between the rod

andthegroundedmetalmeltsthewireandtheux.

The rod wire joins with the base metal in the work piece to form the weld

bead.Theburninguxformsagasshieldaroundthearcandhelpsto

controltheowofthefusingmetalsthatformtheweldbead.

The type and thickness of the metal and the position of the work

piece determines the electrode type and the amount of heat needed

in the welding process. Heavier and thicker metals require more heat

(amperage).

There is no hard and fast rule that determines the exact rod or heat setting

required for every situation. To check the rod requirements for particular

applications, refer to the rod guide on your welder, and then experiment on

some scrap metal.

• 13 •

Low vs High Voltage Welding Electrodes

Make certain you have the best electrode for the welding job you intend

to do. Electrode manufacturers make most of the standard welding

electrodes in two basic types. One type has been designed to run on

welders with high Open Circuit Voltage. The other type electrode is

designed to run on welders with Low Open Circuit Voltage. Most of your

welding will probably be done with low open circuit voltage AC rods such

asE-6013orE-7014generalpurposerods.Userodsof1/16,5/64,or

3/32inchdiameter(thethickertherod,themoreexperienceyouneed.)

Highopencircuitvoltagerodssuchas6011,7018,etc.willnotworkwith

mostlowpowerwelders(100ampsandsmaller).

Electrode manufacturers have adopted a uniform marking code for

weldingelectrodes.Eachelectrodeismarkedwithaprexletterandfour

numbers.Eachofthenumbershasaparticularsignicance.Forexample:

a commonly used general purpose electrode is marked E-6013. The E

signiestheelectrodeisforelectricarcapplications.

Thersttwodigitsinthenumberindicatetheminimumtensilestrength,

of the deposited metal, in thousands of pounds per square inch. In this

instance, 60 indicates the melting rod will have a minimum tensile strength

of 60,000 p.s.i. The third number indicates the welding position for which

the rod is intended. A number 1 indicates for use in any position. Number

2representsanelectroderestrictedtoweldinginhorizontalandat

positions.Number3representsanelectrodeintendedforuseintheat

position only. The fourth digit shows some special characteristics of the

electrode such as weld quality, type of current, or amount of penetration.

For all practical purposes, fourth position marking will not affect the rod

you would normally purchase.

Striking The Arc 4.4

To strike an arc, bring the tip of the rod in contact with the work surface

andthenquicklyraiseituntilthereisabout1/8inch(3.2mm)gapbetween

the rod and the work, as can be seen below.

Theeasiestwaytostrikeanarcistoscratchthetipoftherod(fora

shortdistance)ontheworksurface(asyouwouldstrikeamatch),then

quicklyliftittherequired1/8inch(3.2mm).Itisimportantthatthegap

be maintained during the welding process and that it be neither too wide

or too narrow. If the gap becomes too narrow, the electrode will freeze or

stick to the work piece.

• 14 •

Striking a proper arc and maintaining the gap between the electrode and

the base metal takes practice. A beginner may expect to extinguish any

number of arcs and freeze more than a few electrodes before acquiring

the necessary skill.

Knowing when the arc is just right is a matter of experience. A crisp,
