SAFETY
WELDING SPARKS can
cause fire or explosion.
CYLINDER may explode
if damaged.
4.a. Remove fire hazards from the weld-
ing area. If this is not possible,
cover them to prevent the welding
5.a. Use only compressed gas cylin-
ders containing the correct shield-
ing gas for the process used and
sparks from starting
a
fire.
properly operating regulators
Remember that welding
designed for the gas and
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.
4.b. Where compressed gases are to be used at the job site, spe-
cial precautions should be used to prevent hazardous situa-
tions. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the equip-
ment being used.
pressure used. All hoses, fittings, etc. should be suitable for the
application and maintained in good condition.
5.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
5.c. Cylinders should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
4.c. When not welding, make certain no part of the electrode cir-
cuit is touching the work or ground. Accidental contact can
cause overheating and create a fire hazard.
5.d. Never allow the electrode, electrode holder or any other elec-
trically “hot” parts to touch a cylinder.
4.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even though they have
been “cleaned”. For information, purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances,” AWS F4.1 from the American Welding Society
(see address above).
5.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
5.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for use.
5.g. Read and follow the instructions on compressed gas cylin-
ders, associated equipment, and CGA publication P-I,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.
4.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
4.f. Sparks and spatter are thrown from the welding arc. Wear oil
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
eat plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a weld-
ing area.
FOR ELECTRICALLY pow-
ered equipment.
6.a. Turn off input power using the dis-
connect switch at the fuse box
before working on the equipment.
4.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits.
This can create fire hazards or overheat lifting chains or
cables until they fail.
6.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s rec-
ommendations.
6.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.
4.h. Also see item 7c.

SAFETY
FOR ENGINE
powered equipment.
ELECTRIC AND MAGNETIC
FIELDS
may be dangerous
7.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
8.a. Electric current flowing through any conductor causes local-
ized Electric and Magnetic Fields (EMF). Welding current cre-
ates EMF fields around welding cables and welding
machines.
7.b.Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
8.b. EMF fields may interfere with some pacemakers, and welders
have a pacemaker should consult their physician before
welding.
7.c. Do not add the fuel near an open flame
welding arc or when the engine is run-
ning. Stop the engine and allow it to cool
before refueling to prevent spilled fuel
from vaporizing on contact with hot
engine parts and igniting. Do not spill
fuel when filling tank. If fuel is spilled,
wipe it up and do not start engine until
fumes have been eliminated.
8.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
8.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
8.d.1. Route the electrode and work cables together -
Secure them with tape when possible.
8.d.2. Never coil the electrode lead around your body.
8.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.
7.d. Keep all equipment safety guards, covers
and devices in position and in good
repair. Keep hands, air, clothing and
tools away from V-belts, gears, fans and
all other moving parts when starting,
operating, or repairing equipment.
8.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.
8.d.5. Do not work next to welding power source.
7.e. In some cases it may be necessary to remove safety guards
to perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.
7.f. Do not put your hands near the engine fan. Do not attempt
to override the governor or idler by pushing on the throttle
control rods while the engine is running.
7.g. To prevent accidentally starting gasoline engines while turn-
ing the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.
7.h. To avoid scalding, do not remove the
radiator pressure cap when the engine
is hot.

SAFETY
7. Quand on ne soude pas, poser la pince à une endroit isolé
PRÉCAUTIONS DE SÛRETÉ
de la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suiv-
antes:
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de la faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le
risque de voir passer le courant de soudage par les chaines
de levage, câbles de grue, ou atres circuits. Cela peut
provoquer des risques d’incendie ou d’echauffement des
chaines et des câbles jusqu’à ce qu’ils se rompent.
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter tou-
jours tout contact entre les parties sous tension et la
peau nue ou les vétements mouillés. Porter des gants
secs et sans trous pour isoler les mains.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumées toxiques.
b. Faire trés attention de bien s’isoler de la masse quand
on soude dans des endroits humides, ou sur un planch-
er metallique ou des grilles metalliques, principalement
dans les positions assis ou couché pour lesquelles une
grande partie du corps peut être en contact avec la
masse.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opéerations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les
vapeurs du solvant pour produire du phosgéne (gas forte-
ment roxique) ou autres produits irritants.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
PRÉCAUTIONS DE SÛRETÉ POUR LES
MACHINES À SOUDER À TRANSFOR-
MATEUR ET À REDRESSEUR
d. Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous ten-
sion des porte-électrodes connectés à deux machines à
souder parce que la tension entre les deux pinces peut
être le total de la tension à vide des deux machines.
1. Relier à la terre le chassis du poste conformement au code
de l’électricité et aux recommendations du fabricant. Le dis-
positif de montage ou la piece à souder doit être branché à
une bonne mise à la terre.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enroule le câble-électrode autour de n’importe quelle partie
du corps.
2. Autant que possible, l’installation et l’entretien du poste
seront effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la
debrancher à l’interrupteur à la boite de fusibles.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
4. Garder tous les couvercles et dispostifis de sûreté à leur
place.
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du
rayonnement de l’arc et des projections quand on soude
ou quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnementde
l’arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflamma-
bles.
4. Des gouttes de laiter en fusion sont émises de l’arc de
soudage. Se protéger avec es vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pan-
talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir ttout risque d’incendie dû étincelles.

SAFETY PRECAUTIONS
HIGH FREQUENCY PRECAUTIONS
If possible, locate the Power Wave away from radio
controlled machinery. The normal operation of the
Power Wave may adversely affect the operation of RF
controlled equipment, which may result in bodily injury
or damage to the equipment.
WARNING
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
INPUT CONNECTIONS
• Turn the input power OFF at the
disconnect switch or fuse box
before working on this equipment.
Be sure the voltage, phase, and frequency of the input
power is as specified on the rating plate, located on
the rear of the machine. See Figure A.1 for the loca-
tion of the rating plate.
• Do not touch electrically hot parts.
• Always connect the Power Wave grounding terminal
(located inside the reconnect input access doors).
FIGURE A.1 - RATING PLATE LOCATION
SELECT SUITABLE LOCATION
Place the welder where clean cooling air can circulate
in through the rear louvers and out through the side
and front louvers. Dirt, dust, or any foreign material
that can be drawn into the welder should be kept at a
minimum. Using filters on the air intake to prevent dirt
from building up restricts air flow. Do not use such fil-
ters. Failure to observe these precautions can result in
excessive operating temperatures and nuisance shut-
downs.

The Power Wave may be used outdoors. Power Wave
power sources carry an IP23 enclosure rating. They
are rated for use in damp, dirty environments subject
to occasional falling water such as rain. However, the
best practice is to keep the machine in a dry, sheltered
area, since a wet environment speeds corrosion of
parts. Do not place the machine in puddles or other-
wise submerge parts of the machine in water. This
may cause improper operation and is a possible safe-
ty hazard.

DESIGN FEATURES AND ADVANTAGES
GENERAL DESCRIPTION
• Designed to NEMA Standards.
• Multiple process output ranges 5 - 540 amps.
• 2-line LCD display.
The INVERTEC Power Wave power source is a high
performance, digitally controlled inverter welding
power source capable of complex, high-speed wave-
form control. It uses three-phase input power only.
The Power Wave is designed to be used as a synergic
welding system in conjunction with a wire feeder.
• Easy access for input connections. Connections
are simple strip and clamp (no lugs required).
SYNERGIC WELDING
• Modular construction for easy servicing.
• Thermostatically protected.
The Power Wave system is designed primarily as a
synergic welding system. The word “synergic” comes
from the word “synergism,” which means “two or more
things working together to achieve an effect which nei-
ther can achieve individually.”
• Electronic overcurrent protection.
• Overvoltage protection.
• Digital signal processor and microprocessor control.
The Power Wave and wire feeder operate as a team.
Each “knows” what the other is doing at all times.
They each also know what process, wire type, wire
size, and gas combination are being used. In a syner-
gic system, the wire feeder and power source must
“talk” together. This means that only certain wire feed-
ers can work in a synergic setup. A synergic feeder
has special circuitry to “talk” with and “listen” to the
Power Wave power source.
• RS232 interface for future welding application
updates.
• Simple, reliable reconnection for various input volt-
ages.
• New accessories and wire feeders communicate
using a digital current loop to transfer information.
• Auto device recognition simplifies accessory cable
connections.
Welding experts have preprogrammed the system for
the best range of process settings according to wire
type, wire size, and gas combination. When the wire
feed speed is changed, the system automatically
adjusts the current and voltage waveforms to give the
best weld characteristics. This improves the sound-
ness, appearance, and repeatability of welds.
• Direct support of two wire feeders.
• Auto-configurable for either metric or English mode.
• Multiprocess control: Stick, short arc, GMAW spray,
GMAW pulse, and flux cored arc welding (FCAW).
• Simple control through use of overlays that limit
access to only those keys required for a given appli-
cation.
Refer to the Accessories section of this manual for
available wire feeders.
RECOMMENDED PROCESSES
WELDING CAPABILITY
The Power Wave is designed to be used as a multiple
process machine. It comes preprogrammed with
GMAW pulse, GMAW (short arc and spray) FCAW
(Innershield™ and Outershield™), and stick proce-
dures.
The Power Wave 450 is rated at 450 amps, 38 volts at
60% duty cycle based on a ten minute time period. It
is capable of higher duty cycles at lower output cur-
rents. If the duty cycles are exceeded, a thermostat
will shut off the output until the machine cools to a rea-
sonable operating temperature.
OPERATIONAL FEATURES AND
CONTROLS
LIMITATIONS
• The Power Wave is not recommended for process-
es other than those specified by available overlays.
The Power Wave, through use of a keypad overlay
system, provides various options and controls such as
Multiple Process/Procedure Selection; Memory
Storage of Procedures; Weld from Memory Only oper-
ation; Dual Process/Dual Feeder capability.
• The Power Wave is not recommended for pipe
thawing.

the following places:
B. Negative Polarity Voltage Sensing:
In some welding applications (such as Inner-
shield®) the electrode cable is connected to the -
output terminal and the work cable is connected
to the + output terminal of the power source. This
is negative polarity voltage sensing illustrated by
Figure B.11. When the Power Wave and the wire
feeder(s) are connected in this manner, the arc
voltage can be measured in one of four ways.
These four ways are shown in Table B.2.

OPERATION
Increasing the arc length by 10 percent at a given wire
feed speed also increases all the other arc length set-
tings of the procedure by 10 percent. In the GMAW
Pulse process, the display shows the Procedure
Description, WFS and Arc Length Trim. Arc length trim
is programmed to a default at the factory and may be
adjusted on the wire feeder. When the trigger is
pulled, the WFS, Actual Arc Voltage and Actual Arc
Current are displayed.
OVERVIEW OF WELDING
PROCEDURES
FLUX CORED ARC WELDING (FCAW)
AND GMAW PROCEDURES
For each wire feed speed, a corresponding voltage
has been preprogrammed into the machine by welding
experts. This preprogrammed voltage is the best
average voltage for the procedure at the given wire
feed speed. If the wire feed speed is changed on the
wire feeder, the voltage automatically changes with it.
STICK/TIG
PROCEDURES
Stick welding can be performed with the Power Wave
by attaching a remote control kit to the 6-pin amphe-
nol on the front of the machine. The K941-1 remote
control kit is recommended. Select the stick process
from either the GMAW Pulse, GMAW FCAW, stick
process selection overlay, or recall it from a previously
stored memory location with a Weld From Memory
overlay. When this process is selected, the Power
Wave reads the current (amps) setting from the remote
control kit. It also controls the output of the machine
based on the position of the Output Terminals switch,
which is also located on the remote control kit. When
this switch is in the ON position, the output terminals
of the Power Wave are electrically hot. When the
switch is in the OFF position, the output terminals of
the Power Wave are electrically cold and the machine
cannot produce an output. In the stick process, the
LCD display shows Procedure Description, and Preset
Current (SET=). The Current Trim is always equal to 1
(T=1.00). When the trigger is pulled the Preset Current,
Actual Arc Voltage and Actual Arc Current are dis-
played.
In some cases, the operator may want to change the
preprogrammed voltages; for example, to compensate
for cable and fixture voltage drops. The preset volt-
ages can be adjusted on the wire feeder’s Voltage dis-
play. When a change is made to the voltage at one
wire-feed speed, this change is applied to all other
wire feed speed settings. For example, if the operator
turns up the voltage by 10 percent, the machine auto-
matically increases the preset voltages at all the other
wire feed speeds by 10 percent. In the GMAW FCAW
process, the display shows the Procedure Description,
WFS and Preset Voltage. The preset voltage which
was programmed at the factory, may be changed on
the wire feeder voltage display. Note that, if you
change the default preset voltage up or down, a
V
respective “ ” or “V” sign will be displayed after the
preset value. When the gun trigger is pulled, note that
the display changes to show WFS, Actual Arc Voltage
and Actual Arc Current. See Table B.5 for display
summary.
PULSE PROCEDURES
In these procedures, the actual voltage greatly
depends on the waveform used. The peak currents,
background currents, rise times, fall times, and pulse
times all affect the actual voltage. The actual voltage
for a given wire feed speed is not directly predictable
unless the waveform is known. In this case, it is not
practical to preset an actual voltage for the procedure.
Instead, an arc length adjustment is provided. The
machine “knows” what the best arc length is at the
given wire feed speed but allows the operator to
change it.
See Tables B.3 through B.6 for a summary of the infor-
mation discussed above.
WAVE CONTROL
The wave control settings of all procedures can be
changed on the Power Wave GMAW Pulse, GMAW
FCAW, Stick Process Selection Overlay. The wave
control is a setup parameter that may be adjusted
when the welding procedures are set. This feature
provides an easy way to change the arc behavior with-
out creating a new procedure. The wave control set-
ting of a procedure limits the speed at which the cur-
rent waveform of that procedure can change. Typically,
each procedure is programmed to have average wave
control (at the center of the scale).
The arc length can be adjusted between 0.5 and 1.5
on the wire feeder’s Voltage display. An arc length trim
of 1.0 means that no adjustments will be made to the
preset arc lengths. An arc length trim greater than 1.0
increases the preset arc lengths. An arc length trim
less than 1.0 decreases the preset arc lengths. The
arc length adjustment is factored in at all wire feed
speed settings. Refer to Table B.6 for summary of arc
length trim.

OPERATION
In Pulse processes:
region between pulse and short arc.
The wave control adjustment allows the frequency set-
ting to vary. Increasing the wave control allows the fre-
quency setting to increase, and decreasing the wave
control allows the frequency setting to decrease.
Varying the wave control setting affects the droplet
transfer and allows fine-tuning for different welding
positions.
The pulsing process greatly affects the heat input
to the workpiece. This can be a valuable tool for
either increasing or decreasing the heat input with a
given process. For instance, it is possible to greatly
increase the heat input when welding steel at high
deposition rates. On the other hand, it is possible to
reduce the heat input using the pulsing process. For
example, heat input is reduced greatly with some of
the low current stainless steel procedures using the
processes programmed into the Power Wave. In all
cases, the Power Wave procedures have been
checked for their ability to deliver a sound weld.
However, the fusion of the weld metal into the work-
piece may be affected. It is the responsibility of the
user to determine if the welds produced are suitable
and sound.
In GMAW and FCAW processes:
The wave control adjusts the inductance. (Inductance
is inversely proportional to pinch.) Increasing the wave
control setting decreases the inductance, which
results in the arc getting colder and pinched tighter.
Decreasing the wave control setting increases the
inductance, which results in the arc getting wider.
In Stick processes:
The Power Wave 450 is optimized for use with a
0.75” (1.9 cm) stickout. The adaptive behavior is pro-
grammed to support a stickout range from 0.5” to
1.25” (1.3 to 3.2 cm). In the low and high end of the
wire feed speed ranges of most processes, the adap-
tive behavior may be restricted. This is a physical
restriction due to reaching the edge of the operating
range for the process. It is possible to achieve adap-
tive behavior for longer stickout lengths. However,
shielding gas is often lost when the stickout is too
long.
The wave control adjusts the arc force. Increasing the
wave control setting increases the arc force, making
the arc more harsh but less likely to stick. Decreasing
the wave control setting decreases the arc force, mak-
ing the arc softer and smoother.
PULSE WELDING
Some people have trouble getting used to the behav-
ior of the pulsing arc. The parameters programmed
into the Power Wave have been thoroughly tested for
their ability to deliver a sound weld with good appear-
ance. There are, however, a few things to keep in mind
when pulse welding.
A longer electrical stickout is often used with the
pulsing process at higher deposition rates. A long
stickout will increase the melt-off rate of the wire. In
pulse welding, like other wire welding processes, the
arc length is determined by the voltage setting. This
voltage is programmed at the factory for each process
and wire feed speed. It may be changed using the
Voltage setting on the wire feeder.
Spatter levels are often very low with the pulse
welding process. Pulsing is often used to eliminate
cleaning operations necessary when using other weld-
ing processes.
When adaptive processes are used, the voltage will
vary with stickout. The machine must change the
voltage to keep a stable arc. It is very important to
recognize this. “Actual” arc voltage when welding will
vary because the stickout will seldom be held at the
nominal 1.9 cm value.
Fume levels are sometimes lower with the pulsing
process. Whether or not you will get lower fume lev-
els depends on the pulsing programs used. Certain
waveform characteristics are necessary to get low
fume levels. Unfortunately, low fume procedures are
harder to weld with than procedures designed to opti-
mize the welding process.
The pulsing process is not slower than other
processes. The process is sometimes less forgiving
when the arc gets on or ahead of the puddle. More
attention must be paid to the weld to avoid losing the
puddle. Speed is a matter of deposition rate. All
things being equal regarding the joint being welded,
the speed will depend on the wire feed speed. The
travel speed is maximized by maintaining a very short
arc. Often the process is “trimmed” down until the arc
“crackles.” The spatter increases slightly, but many of
the advantages of pulsing are retained. When welding
steel, the Power Wave is designed to run well in this

ACCESSORIES
To avoid damage from freezing, the water cooler is
shipped without coolant. The fill spout for the water
cooling unit is located on the back panel of the
machine on the left-hand side. See Figure C.1. The
water cooler reservoir must be filled with coolant
before use.
WATER COOLER USAGE
The Power Wave is equipped with an optional internal
water cooler. We recommend using the water cooler
when welding above 300 amps with argon blends on a
regular basis. The gun heating from pulsing above 300
amps average current is often excessive and leads to
reduced consumable life, reduced gun life, and opera-
tor discomfort. Water cooling greatly increases the
durability of the gun and parts at high current.
Use When Ambient Temperature is Above Freezing:
Use tap, distilled, deionized, or well water. Do not use
salt water.
Use When Ambient Temperature is Below Freezing:
Use a mixture of 50% water and 50% automotive
antifreeze, a mixture of 50% water and 50% pure
ethylene glycol, or any commercial water alcohol
mixture.
There are two water connections on the rear of the
Power Wave. See Figure C.1. Connect the water lines
between these connectors and those on the wire feed-
er. The water is fed through the feeder into the gun.
When a water cooler is used, the water cooler must be
enabled by using the Setup Overlay.
Do Not Use: Any prepacked welding industry coolant
mixture, such as those offered by Miller, OKI,
Bernhard, or Dynaflux. These coolants contain sub-
stances which attack plastic components and may
shorten the life of the system. Once added, these
substances are virtually impossible to purge from the
system. DO NOT USE OIL-BASED COOLANTS OF
ANY TYPE.
The water cooler contains a pressure switch, which is
closed when there is adequate pressure in the water
cooler hose for normal operation. If this pressure
drops, the pressure switch opens. A couple of sec-
onds after the pressure switch opens the water cooler
shuts down. If the water cooler is enabled and the
pressure switch opens, the machine beeps loudly indi-
cating that there is a problem with the water cooler
operation.
When the water-cooled system is turned on for the
first time, the coolant lines must be bled. To accom-
plish this, open the return line at the quick-connect fit-
ting on the back of the Power Wave power source.
The return line is the upper of the two coolant fittings.
Place the return hose FROM THE FEEDER into a
bucket to catch any spilled coolant and turn the
machine off and on several times. Pause each time to
allow the cooler to run a complete 3-second cycle.
After 8 to 15 cycles, coolant will spray from the return
hose with some force, indicating that the system is
purged of air. Replace the return line into the quick-
connect fitting. The system is bled and ready for oper-
ation.

sure airstream. Wipe the sensors (Fig D.4 Item 8)
with a clean, soft cloth. Make sure the sensors are
not scratched in the process.
1. Remove the hex head screws from the sides and
top of the machine. Remove the handle bar and
the machine wrap-around cover. Remove the two
case sides. There are hex head screws on each
side.
11. Check the back of the overlays. If the bar code
(black square(s)) on the back of the overlay is
scratched, apply a dull black spray finish to the
scratched-off areas only. If a large area of the bar
code is scratched off, the machine either will not
recognize the overlay or will mistake the overlay
for another one.
2. Perform the input filter capacitor discharge proce-
dure described at the beginning of the
Maintenance Section.
3. Disconnect the shunt from the negative (-) output
terminal. Failure to do this could cause damage to
the shunt circuitry.
4. Clean the inside of the machine with a low pres-
sure airstream. Be sure to clean the following
components thoroughly (Refer to Figure D.4):
12. Inspect gun and cables for good condition.

5. Examine the capacitors for leakage or oozing.
Replace if needed.
6. Examine the wrap-around and side covers for
dents and breakage. Repair them as needed. The
covers must be kept in good condition to assure
that high voltage parts are protected and that cor-
rect spacings are maintained.
7. Remove welding cables and check the electrical
ground continuity. Use an ohmmeter to measure
the resistance between each output terminal and
an unpainted surface of the machine case. The
meter reading should be 500,000 ohms or more. If
the meter reading is less than 500,000 ohms,
check for electrical components that are not prop-
erly insulated from the case. Correct component
insulation, if needed.

2 Check the water cooler hose for kinks and
other places of reduced water flow. If such
problems were found then correct them and
turn the machine off and on to check if the
beeping has been eliminated.
3. Check the water cooler fluid level. Low fluid
level could cause the pressure to drop.
4. Prime the water cooler. Refer to the Setup
