DUTY CYCLE / THERMOSTATIC  
PROTECTION  
Welder duty cycle is the percentage of  
actual weld time that can occur in a ten  
minute interval. For example, at a 10%  
duty cycle, actual welding can occur for  
one minute, then the welder must cool  
for nine minutes.

gas regulator to 30-35 cfh (cubic  
feet per hour). Release the trigger.  
Ha n d sh ie ld  
Asse m b ly  
1. Cut retainer stiffeners and  
detachable handle away from shield.  
Trim the excess plastic to remove  
sharp edges.  
2. Insert filter lens.  
3. Attach the stiffeners over the pins on  
the lens retainers (See Figure 6).  
NOTE: Shielding gas is not required if  
flux-cored welding wire is used.  
GAS TYPES  
There are 3 types of gas generally used  
for gas metal arc welding; 100% argon,  
a mixture of 75% argon and 25%  
carbon dioxide (C25) or 100% carbon  
dioxide. However, 100% carbon  
dioxide is not recommended due to  
unsatisfactory weld beads. This welder  
does not perform well with 100%  
carbon dioxide. The 75/25 mixture is  
recommended for general steel  
welding. For aluminum welding, use  
100% argon. Cylinders of either type  
gas may be obtained at your local  
welding supply outlet. Secure cylinder  
in place on your welding machine or  
other support to prevent the cylinder  
from falling over.  
7. Remember to close the gas valve  
when finished welding.  
Op e ra t io n  
1. Be sure to read,  
understand, and comply  
with all precautions in  
the General Safety  
MANUAL

Information section. Be  
sure to read the entire section  
entitled Welding Guidelines prior to  
using this equipment.

2. Verify welder is off.  
3. Verify that the surfaces of metals to  
be joined are free from dirt, rust,  
paint, oil, scale or other contam-  
inants. These contaminants make  
welding difficult and cause poor  
welds.  
NOTE: Use of incorrect gas may lead to  
little or no penetration of welding  
bead.

• Wire feed drive roller  
• Gun liner - replace if worn  
• Nozzle/contact tips  
When using Aluminum wire, it is best  
to use a larger size tip than the wire  
size being used. For example:  
• If wire diameter is .030, use .035 tip.  
6. Rotate the Wire Speed Control to  
setting number 5 to start with, then  
adjust as needed after test weld.  
7. Plug the input cord into a proper  
voltage receptacle with proper  
circuit capacity (See Chart under  
circuit requirements on page 1).  
• Wire - this welder will accept either  
4” or 8” diameter spools. Welding wire  
is susceptible to moisture and oxidizes  
over time, so it is important to select a  
spool size that will be used within  
approximately 6 months. For mild steel  
welding, AWS ER70S6 solid wire or  
AWS E71T-GS flux-core wire is  
When using .030 - .035 (.8 - .9 mm) MIG  
or Aluminum wire, use the factory set  
large groove. Aluminum wire is very  
weak and should not have the same  
tension on the drive roller as Flux Core  
or MIG wire should. When tensioning  
Aluminum wire down to the Drive  
Roller, turn the tension screw three full  
turns or until the Drive Roller begins to  
grip the wire and feed it through the  
torch cable.  
8. Switch the welder ON.  
9. Verify that the wire is extended  
1/4” from the contact tip. If not,  
squeeze the trigger to feed  
recommended.  
additional wire, release the trigger,  
and cut wire to proper length.  
• Contact tips - use Campbell Hausfeld,  
Tweco®, and other compatible tips.  
10. Position the wire feed gun near the  
work piece, lower the welding  
• Nozzle - use Tweco® style or compatible  
nozzle. Use Campbell Hausfeld nozzle  
model WT5021 found at place of  
purchase of welder, or use Tweco® style  
nozzle (or compatible nozzle) found at  
local welding supply store.

1. Check condition of weld cables and  
immediately repair or replace any  
cables with damaged insulation.  
There are two grooves in the Drive  
Roller. The small groove is for .024” (.6  
mm) wire and the other is for .030” -  
.035” (.8 - .9 mm) wire. Remove the  
roller cover and flip the drive roll to  
choose the correct groove (see Parts  
Breakdown).  
2. Check condition of power cord and  
immediately repair or replace any  
cord if damaged.  
3. Inspect the condition of the gun tip  
and nozzle. Remove any weld slag.  
Replace gun tip or nozzle if  
damaged.  
FLUX CORE WIRE  
Due to small inconsistencies in wire  
diameter, using one size larger tip is  
recommended. For example:  
• If wire diameter is .030, use .035 tip.

WIRE TYPE AND SIZE

The correct choice of wire type involves  
a variety of factors, such as welding

thickness and condition of surface to be  
welded. The American Welding Society,  
AWS, has set up certain requirements  
for each type of wire.

FLUX-CORE WIRE  
E - 7 0 T - GS  
This line of welding machines can  
utilize the Flux Cored Arc Welding  
(Gasless) process or the Gas Metal Arc  
Welding (MIG) process. The weld must  
be protected (shielded) from  
contaminates in the air while it is  
molten. The gasless process uses a  
tubular wire with a flux material inside.  
The flux creates a shielding gas when  
melted. The MIG process uses inert gas  
to shield the weld while molten.  
When current is produced by a  
transformer (welding machine) and  
flows through the circuit to the weld  
wire, an arc is formed between the end  
of the weld wire and the work piece.  
This arc melts the wire and the work  
piece. The melted metal of the weld  
wire flows into the molten crater and  
forms a bond with the work piece as  
shown (Figure 9).

WIRE SPEED  
The wire speed is controlled by the  
knob on the front panel. The speed  
needs to be “ t u n e d ” to the rate at  
which the wire is being melted in the  
arc. Tuning is one of the most critical  
functions in wire feed welding. Tuning  
should be performed on a scrap piece  
of metal the same type and thickness as  
that to be welded. Begin welding with  
one hand “dragging” the gun nozzle  
across the scrap piece while adjusting  
the wire speed with the other hand.  
Too slow of speed will cause sputtering  
and the wire will burn up into the  
contact tip. Too fast a speed will also  
cause a sputtering sound and the wire  
will push into the plate before melting.  
A smooth buzzing sound indicates the  
wire speed is properly tuned. For  
a lu m in u m , wire speed is typically set  
higher (7 - 9 speed range).  
AWS E71T-GS or E71T-11 is  
recommended for this welder.

WELD ANGLE  
Arc We ld in g Ba sics  
Weld angle is the angle at which the  
nozzle is held during the welding  
process. Using the correct angle  
ensures proper penetration and bead  
formation. As different welding  
positions and weld joints become  
necessary, nozzle angle becomes an  
increasingly important factor in  
obtaining a satisfactory weld. Weld  
angle involves two positions - travel  
angle and work angle.  
Five basic techniques affect weld  
quality. These are: wire selection, heat  
setting, weld angle, wire speed, and  
travel speed. An understanding of  
these techniques is necessary for  
effective welds.  
NOTE: Repeat the tuning procedure  
each time there is a change in heat  
setting, wire diameter or type, or work  
piece material type or thickness.  
HEAT SETTING  
The correct heat involves the adjust-  
ment of the welding machine to the  
required setting. Heat or voltage is  
regulated by a switch on the welder.  
The heat setting used depends on the  
size (diameter) and type of wire,  
position of the weld, and the thickness  
of the work piece. Consult specif-  
TRAVEL SPEED  
Travel angle is the angle in the line of  
welding and may vary from 5º to 45º  
from the vertical, depending on  
welding conditions.  
The travel speed is the rate at which  
the torch is moved across the weld  
area. Factors such as diameter and type  
of weld wire, amperage, position, and  
Work angle is the angle from hori-

is easier than any of the others because  
welding speed can be increased, the  
molten metal has less tendency to run,  
better penetration can be achieved,  
and the work is less fatiguing. Welding  
is performed with the wire at a 45º  
travel angle and 45º work angle.  
completing a good weld (See Fig. 11).  
When the speed is too fast, the bead is  
narrow and bead ripples are pointed as  
shown. When the speed is too slow, the  
weld metal piles up and the bead is  
high and wide. For a lu m in u m , travel  
speed is typically faster.  
Root  
Other positions require different  
techniques such as a weaving pass,  
circular pass, and jogging. A higher skill  
level is required to complete these  
welds.

WARNING  
Overhead welding is the least desirable  
position as it is the most difficult and  
dangerous. Heat setting and wire  
selection will vary depending upon the  
position.  
After completing the weld, wait for the  
welded sections to cool. A protective  
coating called slag now covers the weld  
bead which prevents contaminants in  
the air from reacting with the molten  
metal. Once the weld cools to the point  
that it is no longer glowing red, the  
slag can be removed. Removal is done  
with a chipping hammer. Lightly tap  
the slag with the hammer and break it  
loose from the weld bead. The final  
clean-up is done with a wire brush.  
All work should be performed in the  
flat position if possible. For specific  
applications, consult an arc welding  
technical manual.  
WELD PASSES  
Sometimes more then one pass is  
necessary to fill the joint. The root pass  
is first, followed by filler passes and the  
cover pass. If the pieces are thick, it may  
be necessary to bevel the edges that  
are joined at a 60º angle.  
Fig u re 13 - Mu lt ip le We ld Pa sse s  
NOTE: When making multiple weld  
passes, remove the slag before each  
pass.  
NOTE: Remember to remove the slag  
before each pass for gasless process.

The type and thickness of the work

should point out in front of the weld

should point into the puddle to increase  
weld penetration. This is called

Glo ssa ry o f We ld in g Te rm s  
AC o r Alt e rn a t in g Cu rre n t - electric  
current that reverses direction  
periodically. Sixty cycle current travels  
in both directions sixty times per  
second.  
Flu x Co re d Arc We ld in g (FCAW) -  
Sla g - a layer of flux soot that protects  
the weld from oxides and other  
contaminants while the weld is  
solidifying (cooling). Slag should be  
removed after weld has cooled.  
also called Gasless, is a welding process  
used with a wire-feed welding  
machine. The weld wire is tubular with  
flux material contained inside for  
shielding.  
Arc Le n g t h - the distance from the  
end of the electrode to the point  
where the arc makes contact with the  
work surface.  
Sp a t t e r - metal particles thrown from  
the weld which cool and harden on the  
work surface. Spatter can be minimized  
by using a spatter resistant spray on the  
work piece before welding.  
Ga s Me t a l Arc We ld in g (GMAW) -  
also called MIG, is a welding process  
used with a wire feed welding  
machine. The wire is solid and an inert  
gas is used for shielding.  
Ba se Me t a l - the material to be  
welded.  
Ta ck We ld - weld made to hold parts  
in proper alignment until final welds  
are made.  
Ga s Tu n g st e n Arc We ld in g (GTAW) -  
also called TIG, is a welding process  
used with welding equipment with a  
high frequency generator. The arc is  
created between a non-consumable  
Bu t t Jo in t - a joint between two  
members aligned approximately in the  
same plane.  
Tra ve l An g le - the angle of the  
electrode in the line of welding. It  
varies from 5º to 45º depending on  
welding conditions.  
Cra t e r - a pool, or pocket, that is  
formed as the arc comes in contact with tungsten electrode and the work piece.  
the base metal. Filler metal may or may not be used.  
T Jo in t - made by placing the edge of  
one piece of metal on the surface of  
the other piece at approximately a 90º  
angle.  
DC o r Dire ct Cu rre n t - electric current La p Jo in t - a joint between two  
which flows only in one direction. The  
polarity (+ or -) determines which  
direction the current is flowing.  
overlapping members in parallel  
planes.  
Op e n Circu it Vo lt a g e (OCV) - the  
voltage between the electrode and the  
work clamp of the welding machine  
when no current is flowing (not  
welding). The OCV determines how  
quickly the arc is struck.  
Un d e rcu t - a condition that results  
when welding amperage is too high.  
The excessive amperage leaves a  
groove in the base metal along both  
sides of the bead which reduces the  
strength of the weld.  
DC Re ve rse Po la rit y - occurs when  
the electrode holder is connected to  
the positive pole of the welding  
machine. Reverse Polarity directs more  
heat into melting the electrode rather  
then the work piece. It is used on  
thinner material.  
Ove rla p - occurs when the amperage is  
set too low. In this instance, the molten  
metal falls from the electrode without  
actually fusing into the base metal.  
We ld Po o l o r Pu d d le - a volume of  
molten metal in a weld prior to its  
solidification as weld metal.  
DC St ra ig h t Po la rit y - occurs when  
the electrode holder is connected to  
the negative pole of the welding  
machine. With straight polarity more  
heat is directed to the work piece for  
better penetration on thicker material.  
We ld Be a d - a narrow layer or layers of  
metal deposited on the base metal as  
the electrode melts. Weld bead width is  
typically twice the diameter of the  
electrode.  
Po ro sit y - gas pockets, or cavities,  
formed during weld solidification. They  
weaken the weld.  
Pe n e t ra t io n - the depth into the work  
piece that has been heat effected by  
the arc during the welding process. A  
good weld achieves 100% penetration  
meaning that the entire thickness of  
the work piece has been heated and  
resolidified. The heat effected area  
should be easily seen on the opposite  
side of the weld.  
Ele ct ro d e - a coated metal wire having  
approximately the same composition as  
the material being welded.  
Wo rk An g le - the angle of the  
electrode from horizontal, measured at  
right angles to the line of welding.  
Fille t We ld - approximately a triangle  
in cross-section, joining two surfaces at  
right angles to each other in a lap, T or  
corner joint.  
Flu x - a coating, when heated, that  
produces a shielding gas around the  
welding area. This gas protects the

electrode to support the arc. Shielding  
is achieved by the melting of the flux  
coating on the electrode.
