Installation
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.
● Place the welder in an area that
provides at least 12” (30,48 cm) of
ventilation space at both the front
and rear of the unit. Keep all
obstructions away from this
ventilation space.
● Store wire in a clean, dry location
with low humidity to preserve the
wire 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 electric arc
welding machines. The voltage drop
in the extension cord may significantly degrade the performance of
the welder.

socket and the ground clamp cable to
the (-) socket on the front panel. For
flux-core (no-gas) welding, connect
torch to (-) and work clamp to (+).
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.
Internal components of this welder are
protected from overheating with an
automatic thermal switch. A yellow
lamp is illuminated on the front panel

DANGER
or death! Always secure gas cylinders
to the tank bracket kit, a wall or other
fixed support to prevent the cylinder
from falling over. Read, understand,
and follow all the compressed gases
and equipment hazards in the safety
instructions.
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.
NOTE: Use of incorrect gas may lead to
little or no penetration of welding
bead.
REGULATOR (NOT INCLUDED)
The regulator provides a constant
shielding gas pressure and flow rate
during the welding process.
HOOKUP PROCEDURE
Cylinder gas is
under high
pressure. Point cylinder outlet away
from yourself and any bystanders
before opening.
! WARNING
1. These units fit a 20 cubic ft bottle.
2. With the cylinder securely installed,
remove the cylinder cap, stand to the
side of the cylinder opposite the
outlet, and open the valve slightly,
turning counterclockwise. When gas
is emitted from the cylinder, close the
valve by turning clockwise. This will
blow out dust or dirt that may have
accumulated around the valve seat.
3. Install the regulator onto the
cylinder valve, keeping the face of
the gauges in the vertical position
and tighten the stem nut securely
to the gas valve.
4. Install one end of the gas hose (not
included) to the fitting on the rear
of the welder and the other end to
the fitting on the regulator using
hose clamps (not included) on each
connection. Make sure the gas hose
is not kinked or twisted.
5. Once again, stand opposite the
cylinder outlet and slowly open the
cylinder valve. Inspect for leaks in
the connections.
6. Pull the trigger on the gun to allow
the gas to flow. While the trigger is
pulled and gas is flowing, adjust the
gas regulator to 30-35 cfh (cubic
feet per hour). Release the trigger.
7. Remember to close the gas valve
when finished welding.

mechanism, remove screws from the
drive roll housing. Use a small wire
brush to clean the drive roll. Replace
if worn or damaged.
Consumer and Wear Parts
The following parts require routine
maintenance:
• Wire feed drive roller
• Gun liner - replace if worn
• Nozzle/contact tips
• 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
recommended.
• Contact tips - use Campbell Hausfeld,
Tweco®, and other compatible tips.
• 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.
Maintenance
Disconnect power
supply and turn
machine off before inspecting or
servicing any components. Keep the
wire compartment cover closed at all
times unless the wire needs
replacement.
! WARNING
Before every use:
1. Check condition of weld cables and
immediately repair or replace any
cables with damaged insulation.
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.
Do not operate this
! WARNING welding machine
with cracked or missing insulation on
welding cables, wire feed gun, or
power cord.
Every 3 months:
1. Replace any unreadable safety
labels on the welder.
2. Use compressed air to blow all dust
and lint from the ventilation
openings.

Changing Wire Sizes
DRIVE ROLLER
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).
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.
• If wire diameter is .035, use .040 tip.
This welder is setup for .035 (.9 mm)
wire and has a .040 tip. Since this
welder uses .030 and .035 Flux Core
Wire, the drive roller should be in its
factory pre-set condition.
www.chpower.com
6
MIG WIRE
Since MIG wire maintains fair wire
diameter consistency, the contact tip
used should match the wire size used.
When using .024 (.6 mm) wire, use the
small groove on the drive roller. When
using .030 - .035 (.8 - .9 mm) MIG or
Aluminum wire, use the factory set
large groove.
ALUMINUM WIRE
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.
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.

Figure 9 - Weld Components
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).
Arc Welding Basics
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.
HEAT SETTING
The correct heat involves the adjustment 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-
ications listed on the welder. It is
suggested that the welder practice with
scrap metal to adjust settings and
compare welds with Figure 11.
WIRE TYPE AND SIZE
The correct choice of wire type involves
a variety of factors, such as welding
position, work piece material type,
thickness and condition of surface to be
welded. The American Welding Society,
AWS, has set up certain requirements
for each type of wire.

WELD ANGLE
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.
Travel angle is the angle in the line of
welding and may vary from 5º to 45º
from the vertical, depending on
welding conditions.
Work angle is the angle from hori-
zontal, measured at right angles to the
line of welding. For most applications, a
45º travel angle and 45º work angle is
sufficient. For specific applications,
consult an arc welding handbook.

WIRE SPEED
The wire speed is controlled by the
knob on the front panel. The speed
needs to be “tuned” 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
aluminum, wire speed is typically set
higher (7 - 9 speed range).
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.
TRAVEL SPEED
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

Welding Guidelines (Continued)
work piece material thickness all affect
the speed of travel necessary for
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 aluminum, travel
speed is typically faster.
SLAG REMOVAL (FLUX-CORE WIRE
ONLY)
Wear ANSI
approved safety
glasses (ANSI Standard Z87.1) and
protective clothing when removing
slag. Hot, flying debris can cause
personal injury to anyone in the area.
! WARNING
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.
NOTE: When making multiple weld
passes, remove the slag before each
pass.
overhead. Welding in the flat position
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.
Other positions require different
techniques such as a weaving pass,
circular pass, and jogging. A higher skill
level is required to complete these
welds.
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.
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.

Welding Guidelines (Continued)
PUSH VS PULL TECHNIQUE
The type and thickness of the work
piece dictates which way to point the
gun nozzle. For thin materials (18 gauge
and up) and all aluminum, the nozzle
should point out in front of the weld
puddle and push the puddle across the
workpiece. For thicker steel, the nozzle
should point into the puddle to increase
weld penetration. This is called
backhand or pull technique
(See Figure 14).
ALUMINUM WELDING
Any aluminum surface to be welded,
must be cleaned thoroughly with a
stainless steel brush to eliminate any
oxides on the weld and grounding
surface. 100% Argon must be used
when welding aluminum. If Argon is not
used, metal penetration is unlikely.
Supply Cable
Replacement
1. Verify that welder is OFF and power
cord disconnected.
2. Remove welder cover to expose the
ON/OFF switch.
3. Disconnect the black and white
power cord wires connected to the

Glossary of Welding Terms
AC or Alternating Current - electric
current that reverses direction
periodically. Sixty cycle current travels
in both directions sixty times per
second.
Arc Length - the distance from the
end of the electrode to the point
where the arc makes contact with the
work surface.
Base Metal - the material to be
welded.
Butt Joint - a joint between two
members aligned approximately in the
same plane.
Crater - a pool, or pocket, that is
formed as the arc comes in contact with
the base metal.
DC or Direct Current - electric current
which flows only in one direction. The
polarity (+ or -) determines which
direction the current is flowing.
DC Reverse Polarity - 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.
DC Straight Polarity - 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.
Electrode - a coated metal wire having
approximately the same composition as
the material being welded.
Fillet Weld - approximately a triangle
in cross-section, joining two surfaces at
right angles to each other in a lap, T or
corner joint.
Flux - a coating, when heated, that
produces a shielding gas around the
welding area. This gas protects the
parent and filler metals from impurities
in the air.
Flux Cored Arc Welding (FCAW) 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.
Gas Metal Arc Welding (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.
Gas Tungsten Arc Welding (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
tungsten electrode and the work piece.
Filler metal may or may not be used.
Lap Joint - a joint between two
overlapping members in parallel
planes.
Open Circuit Voltage (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.
Overlap - 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.
Porosity - gas pockets, or cavities,
formed during weld solidification. They
weaken the weld.
Penetration - 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.
Slag - 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.
Spatter - 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.
Tack Weld - weld made to hold parts
in proper alignment until final welds
are made.
Travel Angle - the angle of the
electrode in the line of welding. It
varies from 5º to 45º depending on
welding conditions.
T Joint - made by placing the edge of
one piece of metal on the surface of
the other piece at approximately a 90º
angle.
Undercut - 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.
Weld Pool or Puddle - a volume of
molten metal in a weld prior to its
solidification as weld metal.
Weld Bead - 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.
Work Angle - the angle of the
electrode from horizontal, measured at
right angles to the line of welding.
Shielded Metal Arc Welding
(SMAW) - also called Stick, is a welding
process with uses a consumable
electrode to support the arc. Shielding
is achieved by the melting of the flux
coating on the electrode.
