SECTION 1 SAFETY PRECAUTIONS
1.0 Safety Precautions
WARNING: These Safety Precautions are
for your protection. They summarize precautionary information from the references
listed in Additional Safety Information section. Before performing any installation or operating
procedures, be sure to read and follow the safety
precautions listed below as well as all other manuals,
material safety data sheets, labels, etc. Failure to observe
Safety Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS -Some welding, cutting, and gouging
processes are noisy and require ear
protection. The arc, like the sun, emits
ultraviolet (UV) and other radiation
and can injure skin and eyes. Hot metal can cause
burns. Training in the proper use of the processes
and equipment is essential to prevent accidents.
Therefore:
1. Always wear safety glasses with side shields in any
work area, even if welding helmets, face shields, and
goggles are also required.
2. Use a face shield tted with the correct lter and
cover plates to protect your eyes, face, neck, and
ears from sparks and rays of the arc when operating or observing operations. Warn bystanders not
to watch the arc and not to expose themselves to
the rays of the electric-arc or hot metal.
3. Wear ameproof gauntlet type gloves, heavy long-
sleeve shirt, cuess trousers, high-topped shoes,
and a welding helmet or cap for hair protection, to
protect against arc rays and hot sparks or hot metal.
A ameproof apron may also be desirable as protection against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves,
trouser cus, or pockets. Sleeves and collars should
be kept buttoned, and open pockets eliminated from
the front of clothing.
5. Protect other personnel from arc rays and hot
sparks with a suitable non-ammable partition or
curtains.
6. Use goggles over safety glasses when chipping slag
or grinding. Chipped slag may be hot and can y far.
Bystanders should also wear goggles over safety
glasses.
1.1 Safety - English
FIRES AND EXPLOSIONS -- Heat from
ames and arcs can start res. Hot
slag or sparks can also cause res and
explosions. Therefore:
1. Remove all combustible materials well away from
the work area or cover the materials with a protective non-ammable covering. Combustible materials
include wood, cloth, sawdust, liquid and gas fuels,
solvents, paints and coatings, paper, etc.
2. Hot sparks or hot metal can fall through cracks or
crevices in oors or wall openings and cause a hidden smoldering re or res on the oor below. Make
certain that such openings are protected from hot
sparks and metal.“
3. Do not weld, cut or perform other hot work until the
workpiece has been completely cleaned so that there
are no substances on the workpiece which might
produce ammable or toxic vapors. Do not do hot
work on closed containers. They may explode.
4. Have re extinguishing equipment handy for instant
use, such as a garden hose, water pail, sand bucket,
or portable re extinguisher. Be sure you are trained
in its use.
5. Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat and
create a re hazard.
6. After completing operations, inspect the work area
to make certain there are no hot sparks or hot metal
which could cause a later re. Use re watchers when
necessary.
7. For additional information, refer to NFPA Standard
51B, "Fire Prevention in Use of Cutting and Welding
Processes", available from the National Fire Protection Association, Batterymarch Park, Quincy, MA
02269.
ELECTRICAL SHOCK -- Contact with
live electrical parts and ground can
cause severe injury or death. DO NOT
use AC welding current in damp areas,
if movement is conned, or if there is
danger of falling.
5
Page 6
SECTION 1 SAFETY PRECAUTIONS
1. Be sure the power source frame (chassis) is connected to the ground system of the input power.
2. Connect the workpiece to a good electrical
ground.
3. Connect the work cable to the workpiece. A poor
or missing connection can expose you or others
to a fatal shock.
4. Use well-maintained equipment. Replace worn or
damaged cables.
5. Keep everything dry, including clothing, work
area, cables, torch/electrode holder, and power
source.
6. Make sure that all parts of your body are insulated
from work and from ground.
7. Do not stand directly on metal or the earth while
working in tight quarters or a damp area; stand
on dry boards or an insulating platform and wear
rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the
power.
3. Welders should use the following procedures to
minimize exposure to EMF:
A. Route the electrode and work cables together.
Secure them with tape when possible.
B. Never coil the torch or work cable around your
body.
C. Do not place your body between the torch and
work cables. Route cables on the same side of
your body.
D. Connect the work cable to the workpiece as close
as possible to the area being welded.
E. Keep welding power source and cables as far
away from your body as possible.
FUMES AND GASES -- Fumes and
gases, can cause discomfort or harm,
particularly in conned spaces. Do
not breathe fumes and gases. Shielding gases can cause asphyxiation.
Therefore:
9. Turn o the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on
next page) for specic grounding recommendations. Do not mistake the work lead for a ground
cable.
ELECTRIC AND MAGNETIC FIELDS
— May be dangerous. Electric current owing through any conductor causes localized Electric and
Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables
and welding machines. Therefore:
1. Welders having pacemakers should consult their
physician before welding. EMF may interfere with
some pacemakers.
2. Exposure to EMF may have other health eects which
are unknown.
1. Always provide adequate ventilation in the work area
by natural or mechanical means. Do not weld, cut, or
gouge on materials such as galvanized steel, stainless steel, copper, zinc, lead, beryllium, or cadmium
unless positive mechanical ventilation is provided.
Do not breathe fumes from these materials.
2. Do not operate near degreasing and spraying operations. The heat or arc rays can react with chlorinated
hydrocarbon vapors to form phosgene, a highly
toxic gas, and other irritant gases.
3. If you develop momentary eye, nose, or throat irritation while operating, this is an indication that
ventilation is not adequate. Stop work and take
necessary steps to improve ventilation in the work
area. Do not continue to operate if physical discomfort persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below)
for specic ventilation recommendations.

CHAMPS ÉLECTRIQUES ET MAGNÉTIQUES — comportent un risque
de danger. Le courant électrique
qui passe dans n'importe quel con-
ducteur produit des champs électriques et magnétiques localisés. Le soudage et le
courant de coupage créent des champs électriques
et magnétiques autour des câbles de soudage et
l'équipement. Par conséquent :
1. Un soudeur ayant un stimulateur cardiaque doit
consulter son médecin avant d'entreprendre une
opération de soudage. Les champs électriques et
magnétiques peuvent causer des ennuis pour certains stimulateurs cardiaques.
2. L'exposition à des champs électriques et magné-
tiques peut avoir des eets néfastes inconnus pour
la santé.
3. Les soudeurs doivent suivre les procédures suivantes
pour minimiser l'exposition aux champs électriques
et magnétiques :
A. Acheminez l'électrode et les câbles de masse
ensemble. Fixez-les à l'aide d'une bande adhésive
lorsque possible.
B. Ne jamais enrouler la torche ou le câble de masse
autour de votre corps.
C. Ne jamais vous placer entre la torche et les câbles
de masse. Acheminez tous les câbles sur le même
côté de votre corps.
D. Branchez le câble de masse à la pièce à traiter le
plus près possible de la section à souder.
E. Veillez à garder la source d'alimentation pour le
soudage et les câbles à une distance appropriée
de votre corps.
LES VAPEURS ET LES GAZ -- peuvent
causer un malaise ou des dommages
corporels, plus particulièrement
dans les espaces restreints. Ne respirez pas les vapeurs et les gaz. Le
gaz de protection risque de causer
l'asphyxie. Par conséquent :
1. Assurez en permanence une ventilation adéquate
dans l'aire de travail en maintenant une ventilation naturelle ou à l'aide de moyens mécanique.
N'eectuez jamais de travaux de soudage, de coupage ou de gougeage sur des matériaux tels que
l'acier galvanisé, l'acier inoxydable, le cuivre, le zinc,
le plomb, le berylliym ou le cadmium en l'absence
de moyens mécaniques de ventilation ecaces. Ne
respirez pas les vapeurs de ces matériaux.
2. N'eectuez jamais de travaux à proximité d'une
opération de dégraissage ou de pulvérisation.
Lorsque la chaleur
ou le rayonnement de l'arc entre en contact avec les
vapeurs d'hydrocarbure chloré, ceci peut déclencher
la formation de phosgène ou d'autres gaz irritants,
tous extrêmement toxiques.
3. Une irritation momentanée des yeux, du nez ou de la
gorge au cours d'une opération indique que la ventilation n'est pas adéquate. Cessez votre travail an
de prendre les mesures nécessaires pour améliorer
la ventilation dans l'aire de travail. Ne poursuivez
pas l'opération si le malaise persiste.

SECTION 2 DESCRIPTION
2.3.1 Power Source
The power source is a constant current/constant potential, Silicon Controlled Rectier (SCR), three- phase, star-connected
transformer/rectier type dc unit with solid state contactor and control circuitry. It provides the volt-ampere characteristics
desired for conventional MIG, ux core and submerged arc welding in the CV mode or stick welding and arc gouging in the
CC mode.
2.3.2 Volt-Ampere Characteristics
The curves shown in Figure 2-1 represent the volt-ampere static characteristics for the power source. The slant of these
curves is referred to as the "slope" and is generally dened as the "voltage drop per 100 amperes of current use". These curves
show the output voltage available at any given output current from the minimum to the maximum setting of the voltage
control. Because the volt-ampere slope is xed, it is possible to select welding conditions by estimating the open-circuit
voltage required for the load current when operating in the CV mode.

The process switch allows for selection of the output characteristics of the power source depending on the welding process
being used. The CV position produces a “Flat” volt-amp characteristic and is mostly used for the Mig (GMAW) and Submerged
Arc (SAW) welding processes and occasionally with Air Carbon Arc Cutting (CAC-A). The CC position produces a “Drooping”
characteristic most popular for Stick (SMAW), CAC-A and sometimes SAW.
4.1.6 Over Temperature Indicator (Temp.)
This amber light will indicate when an internal overheating condition has occurred and one of the thermal switches has
opened. User control of the solid state contactor will be interrupted and power source output will shut down to protect
critical components. Once cooled to a safe temperature, the thermal switch will automatically reset and output control will
be restored.
4.1.7 Voltmeter and Ammeter
A digital voltmeter and ammeter provides an accurate indication of dc output voltage and current.
4.1.8 Fault Indicator
This red light will illuminate if a short occurs (momentary or permanent) between the +12 volt J1-E; the +10 volt (J2-E) and
either the chassis ground or the negative terminal of the power source. The power source output terminals are de-energized
and the fault must be corrected before resuming operation.
4.1.9 Over Current Protection
The 653cvcc Environmental incorporates automatic over current protection. If an over current condition occurs, the automatic circuitry will “fold back” the output current to a level that will prevent damage to the power source. The power
source will remain in this low current “fold back” mode until the arc is broken, the torch trigger is released or the contactor
switch is reset.
4.1.10 High & Low Inductance Receptacles
The 653cvcc Environmental provides high and low inductance output connections (see gure 3-3). Both are positive output terminals. The high inductance terminal slows the power source dynamic response. This means the output current will
build at a slower rate compared to the low inductance terminals. The welding process and application will determine which
terminal should be used. The chart below provides suggested terminal connections.

SECTION 4 OPERATION
Prior to performing the steps below, open the wall disconnect switch or remove the fuse from the fuse box to electrically
isolate the power source.
4.2.1 General Procedures for the CV-MIG (GMAW), SUB ARC (SAW) and CC-STICK (SMAW),
ELECTRIC SHOCK CAN KILL! "MACHINERY LOCKOUT PROCEDURES"
SHOULD BE EMPLOYED. IF IT IS NOT POSSIBLE TO USE PADLOCKS,
WARNING
SUB ARC (SAW) Processes
A. Make the secondary output connections to the positive and negative output receptacles. See paragraph 3.4 and
gure 3-3.
B. Make the control connections. Refer to the appropriate wire feeder, mechanized control, and/or torch instruction
booklets for additional process requirements or control connections.
ATTACH A RED TAG TO THE LINE DISCONNECT SWITCH OR FUSE BOX
WARNING OTHERS THAT THE CIRCUIT IS BEING WORKED ON.
C. If primary input connections have been made to the power switch, and on the input terminal board to match the
incoming voltage, close the main wall disconnect switch or reinstall fuses in the fuse box.
4.2.2 Specic Procedures for the CV-MIG (GMAW) and SUB ARC (SAW) Processes
A. Set the Output Panel/Remote switch to the desired setting.
B. Set the Process switch to the CV position.
C. Set the contactor switch to "Remote".
ELECTRIC SHOCK CAN KILL! WHEN THE CONTACTOR SWITCH IS IN
THE "ON" POSITION, OUTPUT POWER WILL BE PRESENT THROUGH
WARNING
OUT THE WELDING CIRCUIT; ie. CABLES, WIRE FEEDER, WIRE SPOOL,
DRIVE STAND, GUN, AND ELECTRODE. BE SURE ALL ARE CLEAR OF
THE WORKPIECE OR ARCING WILL RESULT.
D. Set the power switch on the rear panel to the "on" ("I") position. The fan will run for 30 seconds and stop automati-
cally if welding current does not exceed 100 amps. The fan will automatically turn o after 6 minutes when the
contactor is "o" and the welding current is below 100 amps.
E. To preset the approximate welding voltage, place the Contactor switch to the "on" position. This will energize the
power source output, allowing the voltage to be preset using the Output Voltage/Current Control dial and observing the voltmeter.

Page 32
SECTION 4 OPERATION
F. After setting the desired voltage condition, turn the contactor switch back to the “remote” position. This position
requires a remote start control in order to start the welding sequence.
NOTE:
A PCB and resistor pack discharges capacitor voltage to eliminate the electrode "sparking" or "arcing"
potential.
G. Begin welding. Observe the voltmeter, ammeter, and the weld. Readjust the voltage and wire feed speed settings
as necessary to obtain a satisfactory weld.
H. When welding is completed, release torch switch. (This action will de-energize the power source solid state contactor
and remove dc power from the output terminals.)
4.2.3 Specic Procedures for the CC-Stick Welding (SMAW) and Arc Gouging (CAC-A) Processes
A. Place the Output Panel/Remote switch into PANEL position if output current is regulated from the Output Voltage/
Current dial on the panel, or in REMOTE position if output current is regulated from the optional Hand Control.
B. Set the Output Voltage/Current Control to provide the approximate desired welding current using the control knob
as the reference. Example - set knob to “5” for approximately 450 amps output.
C. Set the Contactor switch to the ON position -- this will energize the solid-state contactor and all associated circuitry
up to the output terminals.
D. Place the Process Control switch in the CC position.
E. Commence welding by touch or scratch starting the electrode.○

SECTION 5 MAINTENANCE
5.1 General
If this power source does not operate properly, stop work immediately and investigate the cause of the malfunction. Maintenance
work must be performed by an experienced person, and electrical
CAUTION
WARNING
5.2 Cleaning
work by a trained electrician. Do not permit untrained persons to
inspect, clean, or repair this power source. Use only recommended
replacement parts.
BE SURE THAT THE BRANCH CIRCUIT OR MAIN DISCONNECT SWITCH
IS OFF, OR ELECTRICAL INPUT FUSES ARE REMOVED, BEFORE AT
TEMPTING ANY INSPECTION OR WORK INSIDE THE POWER SOURCE.
PLACING THE POWER SWITCH IN THE OFF POSITION DOES NOT RE
MOVE ALL POWER FROM INSIDE THE POWER SOURCE.
Periodically, remove the cover from the power source and blow accumulated dust and dirt from the air passages and interior
components by using clean, dry low pressure air. The frequency of cleaning required depends upon the environment in
which the power source is used.
It is imperative that all air passages be kept as clean as possible in order to allow adequate air ow to provide proper cooling.
After cleaning with low pressure air, check for and tighten any loose hardware, including all electrical connections. Check
for frayed and/or cracked insulation on all power cables and replace if necessary.
FAILURE TO REPLACE WORN OR DAMAGED CABLES MAY RESULT IN
A BARE CABLE TOUCHING A GROUNDED OBJECT. THE RESULTING
WARNING
ELECTRICAL ARC MAY INJURE UNPROTECTED EYES AND WILL PRES
ENT A SERIOUS FIRE HAZARD. BODY CONTACT WITH A BARE CABLE,
CONNECTOR, OR CONDUCTOR MAY RESULT IN SEVERE ELECTRICAL
SHOCK, CAUSING SERIOUS BURNS OR DEATH.
33
Page 34
SECTION 5 MAINTENANCE
5.3 Inspection and Service
Keep the power source dry, free of oil and grease, and protected at all times from damage by hot metal and sparks.
5.3.1 Fan Motor
Keep the fan motor free of accumulated dust and lint.
5.3.2 Transformer
Other than periodically cleaning the dust and dirt from the transformer, no maintenance is required. Ensure that only clean,
dry, low pressure air is used.
5.3.3 Wire Feeder and Control Circuits
These circuits are protected by two 10 amp circuit breakers mounted in the front panel. If these open, the contactor and
wire feeder will not operate.
5.3.4 Over Temperature Protection
If the power source reaches an abnormally high internal temperature, the thermal protection will de-energize the contactor
circuit, shutting down the power source but leaving the cooling fan on. After the power source has cooled to a safe level,
the thermal protection will automatically reset. While de-enerigized, the contactor and wire feeder cannot be operated.
5.3.5 Digital Voltmeter/Ammeter Calibration
To verify the accuracy of the digital volt/ammeter combination, the following calibration procedure can be performed
periodically:
1. Place the Panel/Remote switch in Panel position.
2. Disconnect cables from the output terminals and then connect an accurate DC voltmeter to the output terminals.
3. Place the Contactor switch in the On position.
4. With the primary input power on, turn the Voltage control knob until you get 25V on the DC voltmeter. Compare the
reading with the reading on the digital voltmeter on the front panel.
5. If there is a dierence in the voltage readings, open front control panel by removing the two mounting screws from
the upper corners, remove meter board from its four mounting posts, and adjust the trimpot (R13) on the meter board
with a small screwdriver until the digital meter reading matches the DC voltmeter reading. When satised, reassemble
meter board and front control panel.

SECTION 6 TROUBLESHOOTING
6.1 General
DISCONNECT PRIMARY POWER AT WALL SWITCH, OR CIRCUIT
WARNING
If the power source is operating improperly, the following troubleshooting information may be used to locate the source
of the trouble.
Check the problem against the symptoms in the following troubleshooting guide (Table 6-2). The remedy for the problem
may be quite simple. If the cause cannot be quickly located, open up the unit and perform a simple visual inspection of all
the components and wiring. Check for proper terminal connections, loose or burned wiring or components, blown fuses,
bulged or leaking capacitors, or any other sign of damage or discoloration.
6.2 Testing and Replacing Bridge Assembly Components
The SCRs used in the power source are devices which allow current to ow in only one direction. The SCRs are designed to
provide long trouble-free operation; however, should a failure occur, they may require replacement.
BREAKER, BEFORE ATTEMPTING INSPECTION OR WORK INSIDE THE
POWER SOURCE.
A. Testing SCRs.
1. Remove top and right side panel from the power source.
2. Locate the main rectier assembly containing the SCRs.
3. Electrically isolate main bridge assembly by disconnecting resistor R5.
4. With the ohmmeter on RX1 scale, place the positive lead on the anode (end of SCR with screw threads) and the
negative lead on the cathode (positive output terminal on the front panel). The meter should read minimum of 20
meg ohms.
5. Reverse leads and check each SCR. All readings should again show high resistance. The SCRs are bad if they show
low resistance in either direction.
6. Check the gate circuit on the SCRs by installing a jumper from the gate lead to the anode of the SCR. The meter should
read less than 5 ohms. Remove the jumper from the gate. The meter reading should increase (30-50 ohms).
IMPORTANT
When replacing SCR’s, make sure mounting surfaces are clean. Using Alcoa No. 2 EJC Electrical Joint Compound or an equivalent,
apply a thin coat to the SCR mounting surface and positively locate in place on the heatsinks. Place the clamp in position with the
bolts through the holes in the heatsinks and proceed as follows:
