with this procedure! The possible hazards are shown in
the adjoining symbols.
rom _nd_3/05
Marks a special safety message.
Means “Note”; not safety related.
1-2.Arc Welding Hazards
The symbols shown below are used throughout this manual to
call attention to and identify possible hazards. When you see the
symbol, watch out, and follow the related instructions to avoid the
hazard. The safety information given below is only a summary of
the more complete safety information found in the Safety Standards listed in Section 1-7. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and re-
pair this unit.
During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks or
severe burns. The electrode and work circuit is electrically
machine internal circuits are also live when power is on. In semiautomatic or
automatic wire welding, the wire, wire reel, drive roll housing, and all metal
parts touching the welding wire are electrically live. Incorrectly installed or
improperly grounded equipment is a hazard.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats or covers
big enough to prevent any physical contact with the work or ground.
Do not use AC output in damp areas, if movement is confined, or if there is a
danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on unit.
Additional safety precautions are required when any of the following electri-
cally hazardous conditions are present: in damp locations or while wearing
wet clothing; on metal structures such as floors, gratings, or scaffolds;
when in cramped positions such as sitting, kneeling, or lying; or when there
is a high risk of unavoidable or accidental contact with the workpiece or
ground. For these conditions, use the following equipment in order presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most
situations, use of a DC, constant voltage wire welder is recommended.
And, do not work alone!
Disconnect input power or stop engine before installing or servicing this
equipment. Lockout/tagout input power according to OSHA 29 CFR
1910.147 (see Safety Standards).
Properly install and ground this equipment according to its Owner’s Manual
and national, state, and local codes.
Always verify the supply ground — check and be sure that input power cord
ground wire is properly connected to ground terminal in disconnect box or
that cord plug is connected to a properly grounded receptacle outlet.
When making input connections, attach proper grounding conductor first −
double-check connections.
Frequently inspect input power cord for damage or bare wiring — replace
cord immediately if damaged — bare wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly with a sep-
arate cable.

ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary actions
to avoid the hazards.
Do not touch electrode holders connected to two welding machines at
the same time since double open-circuit voltage will be present.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to workpiece or work-
table as near the weld as practical.
Insulate work clamp when not connected to workpiece to prevent contact
with any metal object.
Do not connect more than one electrode or work cable to any single weld
output terminal.
SIGNIFICANT DC VOLTAGE exists in inverters after stopping engine.
Stop engine on inverter and discharge input capacitors according to
instructions in Maintenance Section before touching any parts.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing these fumes
and gases can be hazardous to your health.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use local forced ventilation at the arc to
remove welding fumes and gases.
If ventilation is poor, wear an approved air-supplied respirator.
Read and understand the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings, cleaners,
and degreasers.
Work in a confined space only if it is well ventilated, or while wearing an air-
supplied respirator. Always have a trained watchperson nearby. Welding
fumes and gases can displace air and lower the oxygen level causing injury
or death. Be sure the breathing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying operations.
The heat and rays of the arc can react with vapors to form highly toxic and
irritating gases.
Do not weld on coated metals, such as galvanized, lead, or cadmium plated
steel, unless the coating is removed from the weld area, the area is well
ventilated, and while wearing an air-supplied respirator. The coatings and
any metals containing these elements can give off toxic fumes if welded.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use approved
air-supplied respirator.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible
and invisible (ultraviolet and infrared) rays that can burn eyes
and skin. Sparks fly off from the weld.
Wear an approved welding helmet fitted with a proper shade of filter lenses
to protect your face and eyes from arc rays and sparks when welding or
watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).
Wear approved safety glasses with side shields under your helmet.
Use protective screens or barriers to protect others from flash, glare, and
sparks; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant material
(leather, heavy cotton, or wool) and foot protection.

WELDING can cause fire or explosion.
HOT PARTS can cause severe burns.
Welding on closed containers, such as tanks, drums, or
pipes, can cause them to blow up. Sparks can fly off from the
equipment can cause fires and burns. Accidental contact of electrode to metal
objects can cause sparks, explosion, overheating, or fire. Check and be sure
the area is safe before doing any welding.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not
possible, tightly cover them with approved covers.
Do not weld where flying sparks can strike flammable material.
Protect yourself and others from flying sparks and hot metal.
Be alert that welding sparks and hot materials from welding can easily go
through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition can cause
fire on the hidden side.
Do not weld on closed containers such as tanks, drums, or pipes, unless
they are properly prepared according to AWS F4.1 (see Safety Standards).
Connect work cable to the work as close to the welding area as practical to
prevent welding current from traveling long, possibly unknown paths and
causing electric shock, sparks, and fire hazards.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at contact tip
when not in use.
Wear oil-free protective garments such as leather gloves, heavy shirt, cuf-
fless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches, from your
person before doing any welding.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B for hot
work and have a fire watcher and extinguisher nearby.
welding arc. The flying sparks, hot workpiece, and hot
FLYING METAL can injure eyes.
Welding, chipping, wire brushing, and grinding cause
sparks and flying metal. As welds cool, they can
throw off slag.
Wear approved safety glasses with side shields even
under your welding helmet.
Do not touch hot parts bare handed.
Allow cooling period before working on equipment.
To handle hot parts, use proper tools and/or wear
heavy, insulated welding gloves and clothing to prevent burns.

MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
Wearers should consult their doctor before going
near arc welding, gouging, or spot welding operations.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode. Since gas cylinders are
normally part of the welding process, be sure to treat them
carefully.
Protect compressed gas cylinders from excessive heat, mechanical
shocks, physical damage, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary support or
cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder — explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and fittings de-
signed for the specific application; maintain them and associated parts in
good condition.
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when cylinder is in use or
connected for use.
Use the right equipment, correct procedures, and sufficient number of per-
sons to llift and move cylinders.

1-8.EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.

LES FUMÉES ET LES GAZ peuvent être
dangereux.
Le soudage génère des fumées et des gaz. Leur inhalation
peut être dangereux pour votre santé.
Eloigner votre tête des fumées. Ne pas respirer les fumées.
À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au niveau de
l’arc pour l’évacuation des fumées et des gaz de soudage.
Si la ventilation est médiocre, porter un respirateur anti-vapeurs approuvé.
Lire et comprendre les spécifications de sécurité des matériaux (MSDS) et les
instructions du fabricant concernant les métaux, les consommables, les revêtements, les nettoyants et les dégraisseurs.
Travailler dans un espace fermé seulement s’il est bien ventilé ou en portant
un respirateur à alimentation d’air. Demander toujours à un surveillant dûment
formé de se tenir à proximité. Des fumées et des gaz de soudage peuvent déplacer l’air et abaisser le niveau d’oxygène provoquant des blessures ou des
accidents mortels. S’assurer que l’air de respiration ne présente aucun danger.
Ne pas souder dans des endroits situés à proximité d’opérations de dégrais-
sage, de nettoyage ou de pulvérisation. La chaleur et les rayons de l’arc
peuvent réagir en présence de vapeurs et former des gaz hautement toxiques
et irritants.
Ne pas souder des métaux munis d’un revêtement, tels que l’acier galvanisé,
plaqué en plomb ou au cadmium à moins que le revêtement n’ait été enlevé
dans la zone de soudure, que l’endroit soit bien ventilé, et en portant un respirateur à alimentation d’air. Les revêtements et tous les métaux renfermant ces
éléments peuvent dégager des fumées toxiques en cas de soudage.
LES ACCUMULATIONS DE GAZ risquent de provoquer des blessures ou
même la mort.
Fermer l’alimentation du gaz protecteur en cas de non utili-

étincelles sont projetées pendant le soudage.
Porter un casque de soudage approuvé muni de verres filtrants approprié
pour protéger visage et yeux pendant le soudage (voir ANSI Z49.1 et Z87.1
énuméré dans les normes de sécurité).
Porter des lunettes de sécurité avec écrans latéraux même sous votre cas-
que.
Avoir recours à des écrans protecteurs ou à des rideaux pour protéger les au-
tres contre les rayonnements les éblouissements et les étincelles ; prévenir
toute personne sur les lieux de ne pas regarder l’arc.

LE SOUDAGE peut provoquer un incendie ou une explosion.
Le soudage effectué sur des conteneurs fermés tels que des
réservoirs, tambours ou des conduites peut provoquer leur
soudure. La projection d’étincelles, des pièces chaudes et des équipements
chauds peut provoquer des incendies et des brûlures. Le contact accidentel de
l’électrode avec des objets métalliques peut provoquer des étincelles, une
explosion, un surchauffement ou un incendie. Avant de commencer le soudage,
vérifier et s’assurer que l’endroit ne présente pas de danger.
Déplacer toutes les substances inflammables à une distance de 10,7 m de
l’arc de soudage. En cas d’impossibilité les recouvrir soigneusement avec des
protections homologués.
Ne pas souder dans un endroit là où des étincelles peuvent tomber sur des
substances inflammables.
Se protéger et d’autres personnes de la projection d’étincelles et de métal
chaud.
Des étincelles et des matériaux chauds du soudage peuvent facilement
passer dans d’autres zones en traversant de petites fissures et des
ouvertures.
Surveiller tout déclenchement d’incendie et tenir un extincteur à proximité.
Le soudage effectué sur un plafond, plancher, paroi ou séparation peut dé-
clencher un incendie de l’autre côté.
Ne pas effectuer le soudage sur des conteneurs fermés tels que des réser-
voirs, tambours, ou conduites, à moins qu’ils n’aient été préparés
correctement conformément à AWS F4.1 (voir les normes de sécurité).
Brancher le câble sur la pièce le plus près possible de la zone de soudage pour
éviter le transport du courant sur une longue distance par des chemins inconnus éventuels en provoquant des risques d’électrocution et d’incendie.
Brancher le câble de masse sur la pièce le plus près possible de la zone de
soudage pour éviter le transport du courant sur une longue distance par des
chemins inconnus éventuels en provoquant des risques d’électrocution,
d’étincelles et d’incendie.
Ne pas utiliser le poste de soudage pour dégeler des conduites gelées.
En cas de non utilisation, enlever la baguette d’électrode du porte-électrode
ou couper le fil à la pointe de contact.
Porter des vêtements de protection dépourvus d’huile tels que des gants en
cuir, une chemise en matériau lourd, des pantalons sans revers, des chaussures hautes et un couvre chef.
Avant de souder, retirer toute substance combustible de vos poches telles
qu’un allumeur au butane ou des allumettes.
Suivre les recommandations dans OSHA 1910.252(a)(2)(iv) et NFPA 51B
pour les travaux à chaud et avoir de la surveillance et un extincteur à proximité.

soudage, les manipuler avec précaution.
Protéger les bouteilles de gaz comprimé d’une chaleur excessive, des chocs
mécaniques, des dommages physiques, du laitier, des flammes ouvertes, des
étincelles et des arcs.
Placer les bouteilles debout en les fixant dans un support stationnaire ou dans
un porte-bouteilles pour les empêcher de tomber ou de se renverser.
Tenir les bouteilles éloignées des circuits de soudage ou autres circuits électri-
ques.
Ne jamais placer une torche de soudage sur une bouteille à gaz.
Une électrode de soudage ne doit jamais entrer en contact avec une bouteille.
Ne jamais souder une bouteille pressurisée − risque d’explosion.
Utiliser seulement des bouteilles de gaz protecteur, régulateurs, tuyaux et rac-
cords convenables pour cette application spécifique; les maintenir ainsi que
les éléments associés en bon état.
Ne pas tenir la tête en face de la sortie en ouvrant la soupape de la bouteille.
Maintenir le chapeau de protection sur la soupape, sauf en cas d’utilisation ou
de branchement de la bouteille.
Utiliser les équipements corrects, les bonnes procédures et suffisamment de
personnes pour soulever et déplacer les bouteilles.

Considérations sur le soudage et les effets de basse fréquence et des
champs magnétiques et électriques.
Le courant de soudage, pendant son passage dans les câbles de soudage, causera des champs électromagnétiques. Il y a eu et il y a encore un
certain souci à propos de tels champs. Cependant, après avoir examiné
plus de 500 études qui ont été faites pendant une période de recherche
de 17 ans, un comité spécial ruban bleu du National Research Council a
conclu : « L’accumulation de preuves, suivant le jugement du comité, n’a
pas démontré que l’exposition aux champs magnétiques et champs électriques à haute fréquence représente un risque à la santé humaine ».
Toutefois, des études sont toujours en cours et les preuves continuent à
être examinées. En attendant que les conclusions finales de la recherche
soient établies, il vous serait souhaitable de réduire votre exposition aux
champs électromagnétiques pendant le soudage ou le coupage.
Pour réduire les champs magnétiques sur le poste de travail, appliquer les

2. Disposer les câbles d’un côté et à distance de l’opérateur.
3. Ne pas courber pas et ne pas entourer pas les câbles autour de
votre corps.
4. Garder le poste de soudage et les câbles le plus loin possible de

help schedule maintenance.
4 Fuel Gauge
Use gauge to check fuel level.
To check fuel level when engine is not run-
ning, turn Engine Control switch to Run position.
5 Battery Voltmeter (Optional)
Use gauge to check battery voltage and moni-
tor the engine charging system. The meter
should read about 14 volts dc when the engine is running, and about 12 volts dc when
the engine is stopped.
6 Engine Coolant Temperature Gauge
(Optional)
Normal temperature is 180 - 203° F (82 - 95°
C). Engine stops if temperature exceeds 220°
F (104° C).
7 Engine Oil Pressure Gauge (Optional)
Normal pressure is 30 − 60 psi (207 − 414
kPa). Engine stops if pressure is below 10 psi
(69 kPa).
Weld Controls
Max OCV Control Circuit: This unit has
a max OCV control circuit that resets Amperage Adjust control R1 to maximum
when the arc breaks. When an arc is
struck, weld output control returns to the
R1 front panel or combination front panel/
remote control setting. The Amperage
Adjust control adjusts amperage only
when welding and does not adjust opencircuit voltage.
The max OCV circuit is disabled when
the Stick/TIG Selection switch is in
Scratch Start TIG position (see item 10).
8 Ampere Range Switch
Do not switch under load.
Use switch to select weld amperage range.
For most welding applications, use lowest
amperage range possible to help prevent arc
outages.
9 Amperage Adjust Control
Control adjusts amperage within range se-
lected by Ampere Range switch. Weld output
would be about 168 A DC with controls set as
shown (50% of 110 to 225 A).
The numbers around the control are for
reference only and do not represent an
actual percentage value.
10 Stick/TIG Selection Switch
Use switch to disable the max OCV circuit
and the arc drive (dig) circuit for scratch start
TIG welding (see max OCV note under Weld
Controls).
When switch is in the Stick position, the max
OCV circuit resets Amperage Adjust Control
R1 to maximum when the arc breaks.
Also in the Stick position, the arc drive (dig)
circuit provides additional amperage during
low voltage (short arc length conditions) to
prevent “sticking” electrodes.
When switch is in Scratch Start TIG position,
the max OCV and arc drive (dig) circuits are
disabled and OCV changes when the control
is adjusted.
11 Amperage Adjust Switch And Remote
Amperage Adjust Receptacle
Connect optional remote control to RC13
(See Section 5-10). Use switch to select front

OM-4421 Page 44
Stop engine.
When a supplementary protector,
circuit breaker or fuse opens, it usually indicates a more serious problem
exists. Contact Factory Authorized
Service Agent.
1 Fuse F1
2 Fuse F2
F1 and F2 protect the stator exciter wind-
ing from overload. If F1 opens, weld and
generator power is low or stops entirely.
If F2 opens, weld output is low or stops
entirely. 4 kVA/kW generator power is still
circuit. If CB4 opens, electrode may stick
to the workpiece more frequently during
low voltage (short arc length) conditions.
CB4 automatically resets when the fault
is corrected.
CB5 protects the 24 volt ac output to remote receptacle RC14, and 24 volt output
to field current regulator board PC1 (CC/
CV models only). If CB5 opens, weld output and 24 volt output to RC14 stops. On
units with optional three-phase generator, generator power output at receptacle
RC5 also stops if CB5 opens.
CB6 protects the 115 volt ac output to remote receptacle RC14 (CC/CV models
only). If CB6 opens, 115 volt output to
RC14 stops.
CB10 protects the engine battery circuit.
If CB10 opens, the engine will not crank.
CB10 automatically resets when the fault
is corrected.
CB11 protects the weld control circuit. On
CC models, if CB11 opens the max OCV
circuit does not work and open circuit
voltage is variable at all times (see max
OCV note under Weld Controls in Section
6-2). If CB11 opens on CV models, weld
output stops (generator power is still
available).
CB12 protects the field flashing circuit. If
CB12 opens, the generator may not excite at start-up and weld and generator
power output may not be available.
CB13 protects the engine control circuit.
If CB13 opens, the engine does not
crank.
CB14 protects throttle solenoid TS1 on
units with auto idle option. If CB14 opens,
the engine does not run at idle speed.
CB14 automatically resets when the fault
is corrected.

SECTION 11 − RUN-IN PROCEDURE
Do not perform run-in
procedure at less than 20
volts weld output and do not
exceed duty cycle or equipment damage may occur.
1 Welding Generator
2
Run diesel engines near rated voltage and current during run-in period
to properly seat piston rings and
prevent wetstacking. See nameplate, rating label, or specifications
section in this manual to find rated
voltage and current.
Do not idle engine longer than
necessary. Piston rings seat
faster if engine runs at weld/
power rpm, and the welding
generator is kept loaded during
run-in.
2 Engine Exhaust Pipe
Wetstacking is unburned fuel and
oil in the exhaust pipe and occurs
during run-in if the engine is run too
long at light load or idle rpm.
If exhaust pipe is coated with a wet,
black, tar-like substance, dry the
engine using one of the following
run-in procedures.
See the engine manual for additional engine run-in information.

AMPERES x VOLTS = WATTS
EXAMPLE 1: If a drill uses 4.5 amperes at 115 volts, calculate its running power
requirement in watts.
4.5 A x 115 V = 520 W
The load applied by the drill is 520 watts.
VOLTS 115
AMPS
Hz
4.5

ST-800 576-B
1 Resistive Load
A light bulb is a resistive load and
requires a constant amount of power.
2 Non-Resistive Load
Equipment with a motor is a non-re-
sistive load and requires approximately six times more power while
starting the motor than when running
(see Section 12-8).
3 Rating Data
Rating shows volts and amperes, or
watts required to run equipment.
OM-4421 Page 58
EXAMPLE 2: If three 200 watt flood lamps are used with the drill from Example 1,
add the individual loads to calculate total load.
(200 W + 200 W + 200 W) + 520 W = 1120 W
The total load applied by the three flood lamps and drill is 1120 watts.

To find starting amperage:
Step 1: Find code and use table to
find kVA/HP. If code is not listed,
multiply running amperage by six to
find starting amperage.
Step 2: Find Motor HP and Volts.
Step 3: Determine starting amper-
age (see example).
Welding generator amperage out-
put must be at least twice the
motor’s running amperage.

1 Limit Load To 90% Of
Generator Output
Always start non-resistive (motor)
loads in order from largest to smallest, and add resistive loads last.
2 5 Second Rule
If motor does not start within 5
seconds, turn off power to prevent
motor damage. Motor requires
more power than generator can
supply.

applicable codes and safety practices.
Properly install and ground this
equipment according to its Owner’s
Manual and national, state, and local
codes.
Customer-supplied equipment is re-
quired if generator will supply standby
power during emergencies or power outages.
1 Utility Electrical Service
2 Transfer Switch (Double-Throw)
Notes
Switch transfers the electrical load from
electric utility service to the generator. Transfer load back to electric utility when service is
restored.
Install correct switch (customer-supplied).
Switch rating must be same as or greater
than the branch overcurrent protection.
3 Fused Disconnect Switch
Install correct switch (customer-supplied) if
required by electrical code.
4 Welding Generator Output
Generator output voltage and wiring must be
consistent with regular (utility) system voltage and wiring.
Connect generator with temporary or permanent wiring suitable for the installation.
Turn off or unplug all equipment connected to
generator before starting or stopping engine.
When starting or stopping, the engine has
low speed which causes low voltage and
frequency.
5 Essential Loads
Generator output may not meet the electrical
requirements of the premises. If generator
does not produce enough output to meet all
requirements, connect only essential loads
(pumps, freezers, heaters, etc. − See Section 12-4).
