This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-
bols and related instructions below for necessary actions to avoid the
hazards.
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
repair this unit.
During operation, keep everybody, especially children, away.
Touching live electrical parts can cause fatal shocks or
severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and 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 equip-
ment is a hazard.
ELECTRIC SHOCK can kill.
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 follow-
ing electrically 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 unavoid-
able 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 volt-
age. 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 conduc-
tor first double-check connections.
Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
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 separate cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Do not touch electrode holders connected to two welding ma-
chines 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 worktable 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 stop-
ping engine.
Stop engine on inverter and discharge input capacitors according
to instructions in Maintenance Section before touching any parts.
HOT PARTS can cause severe burns.
Do not touch hot parts bare handed.
Allow cooling period before working on equip-
ment.
To handle hot parts, use proper tools and/or wear heavy, insu-
lated welding gloves and clothing to prevent burns.
FLYING METAL or DIRT 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.
OM-4430 Page 2
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
FUMES AND GASES can be hazardous.
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 watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breath-
ing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying op-
erations. 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 ap-
proved air-supplied respirator.
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.
ARC RAYS can burn eyes and skin.
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 mate-
rial (leather, heavy cotton, or wool) and foot protection.
Welding on closed containers, such as tanks, drums,
or pipes, can cause them to blow up. Sparks can fly off
from the welding arc. The flying sparks, hot workpiece,
and hot 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.
WELDING can cause fire or explosion.
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).
Do not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).
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 haz-
ards.
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, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
Use only correct fuses or circuit breakers. Do not oversize or by-
pass them.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
NOISE can damage hearing.
Noise from some processes or equipment can dam-
age hearing.
Wear approved ear protection if noise level is
high.
MAGNETIC FIELDS can affect Implanted
Medical Devices.
Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
Shielding gas cylinders contain gas under high pres-
sure. If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding process, be
sure to treat them carefully.
CYLINDERS can explode if damaged.
Protect compressed gas cylinders from excessive heat, mechani-
cal 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 fit-
tings designed 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 num-
ber of persons to lift and move cylinders.
Read and follow instructions on compressed gas cylinders,
associated equipment, and Compressed Gas Association (CGA)
publication P-1 listed in Safety Standards.

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 electro-
magnetic 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 power-
frequency 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.
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from
operator as practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recom-
mended.

-
des.
Prévoir une période de refroidissement avant d
e
travailler à l’équipement.
Ne pas toucher aux pièces chaudes, utiliser les outils recomman
-
dés et porter des gants de soudage et des vêtements épais pou
r
éviter les brûlures.
DES PIECES DE METAL ou DES SA-
LETES peuvent provoquer des bles-
sures dans les yeux.
Le soudage, l’écaillement, le passage de la pièce à la brosse en
fil de fer, et le meulage génèrent des étincelles et des particules
métalliques volantes. Pendant la période de refroidissement des
soudures, elles risquent de projeter du laitier.
Porter des lunettes de sécurité avec écrans latéraux ou un écran
facial.
LES FUMÉES ET LES GAZ peuvent êtr
e
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 dégraissage, de nettoyage ou de pulvérisation. La chaleur et
les rayons de l’arc peuvent réagir en présence de vapeurs et for-
mer 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 revête-
ment 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 ri
s
quent de provoquer des blessures o
u
même la mort.
Fermer l’alimentation du gaz protecteur en cas d
e
non utilisation.
Veiller toujours à bien aérer les espaces confinés ou se servir d’u
n
respirateur d’adduction d’air homologué.
LES RAYONS DE L’ARC peuvent pr
o
voquer des brûlures dans les yeux
e
sur la peau.
Le rayonnement de l’arc du procédé de soudag
e
génère des rayons visibles et invisibles intense
(ultraviolets et infrarouges) susceptibles de provoquer des brûlure
dans les yeux et sur la peau. Des étincelles sont projetées pendant l
e
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 casque.
Avoir recours à des écrans protecteurs ou à des rideaux pour
protéger les autres contre les rayonnements les éblouissements
et les étincelles ; prévenir toute personne sur les lieux de ne pas
regarder l’arc.
Porter des vêtements confectionnés avec des matières résistan-
tes et ignifuges (cuir, coton lourd ou laine) et des bottes de
protection.
Le soudage effectué sur des conteneurs fermés tel
que des réservoirs, tambours ou des conduites pe
u
provoquer leur éclatement. Des étincelles peuve
n
être projetées de l’arc de soudure. La projection d’étincelles, des pièce
chaudes et des équipements chauds peut provoquer des incendies
e
des brûlures. Le contact accidentel de l’électrode avec des objet
métalliques peut provoquer des étincelles, une explosion, un surchau
f
fement ou un incendie. Avant de commencer le soudage, vérifier
e
s’assurer que l’endroit ne présente pas de danger.
LE SOUDAGE peut provoquer un in
cendie ou une explosion.
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 déclencher un incendie de l’autre côté.
Ne pas effectuer le soudage sur des conteneurs fermés tels que
des réservoirs, tambours, ou conduites, à moins qu’ils n’aient été
préparés correctement conformément à AWS F4.1 (voir les nor-
mes de sécurité).
Ne soudez pas si l’air ambiant est chargé de particules, gaz, ou va-
peurs inflammables (vapeur d’essence, par exemple).
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 provo-
quant des risques d’électrocution, d’étincelles et d’incendie.
Ne pas utiliser le poste de soudage pour dégeler des conduites ge-
lées.
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 po-
ches telles qu’un allumeur au butane ou des allumettes.
Une fois le travail achevé, assurezvous qu’il ne reste aucune tra-
ce d’étincelles incandescentes ni de flammes.
Utiliser exclusivement des fusibles ou coupecircuits appropriés.
Ne pas augmenter leur puissance; ne pas les ponter.
OM-4430 Page 8
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

dage par points, de gougeage, du coupage plasma ou de chauf-
fage par induction.
Si des BOUTEILLES sont endomm
a
gées, elles pourront exploser.
Des bouteilles de gaz protecteur contiennent du g
a
sous haute pression. Si une bouteille est endomm
a
gée, elle peut exploser. Du fait que les bouteilles de gaz fo
n
normalement partie du procédé de soudage, les manipuler av
e
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 station-
naire 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 électriques.
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.

2-8. Information EMF
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 sou-
dage, causera des champs électromagnétiques. Il y a eu et il y a encore
un certain souci à propos de tels champs. Cependant, après avoir exa-
miné 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 électromagnéti-
ques pendant le soudage ou le coupage.
Pour réduire les champs magnétiques sur le poste de travail, appliquer
les procédures suivantes :
1. Garder les câbles ensemble, les torsader, les scotcher, ou les
recouvrir d’une housse.
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
vous.
5. Connecter la pince sur la pièce aussi près que possible de la
soudure.
En ce qui concerne les implants médicaux :
Les porteurs d’implants doivent d’abord consulter leur médecin avant
de s’approcher des opérations de soudage à l’arc, de soudage par
points, de gougeage, du coupage plasma ou de chauffage par induc-
tion. Si le médecin approuve, il est recommandé de suivre les
procédures précédentes.

See Section 6-5 for Process switch informa-
tion.
2 Remote Receptacle
Use receptacle to connect remote control.
When a remote voltage/amperage control is
connected to the Remote receptacle, the
Auto Sense Remote feature automatically
switches voltage/amperage control to the re-
mote control (see Sections 5-7 and 6-8).
With remote voltage/amperage control con-
nected, weld output in CC mode is deter-
mined by a combination of front panel and re-
mote control voltage/amperage settings.
If no remote voltage/amperage control is
connected to the Remote receptacle, the
front panel Voltage/Amperage control ad-
justs voltage and amperage.
3 And 4 Displays
Displays can show weld process information
(voltage and amperage) or maintenance in-
formation (hourmeter or oil change count-
down).
Meter Weld Functions: In Wire mode, Volt-
meter displays preset weld voltage when not
welding. Meters display actual voltage and
amperage when welding and for five sec-
onds after welding has stopped.
In Stick and TIG modes, Voltmeter reads ON
and Ammeter displays preset amperage
when not welding. Meters display actual volt-
age and amperage when welding and for five
seconds after welding has stopped.
Meter Engine Maintenance Functions:
Meters display engine hours when Engine
Control switch is in the Run/Idle 3600/2400
position but engine is not running.
Meter Oil Change Countdown: With en-
gine off, place Engine Control switch in Run/
Idle 3000/1800 position to see hours before
next recommended oil change. Oil change
hours start at 100 (fresh oil) and count down
to 0 (oil change due). The meters display
negative () hours if 100 hours is exceeded.
After changing oil, reset counter by cycling
Engine Control switch between Run/Idle
positions three times.
Place Engine Control switch in Off position
after reading meters.
5 Fuel Level Indicator
With Engine running or Engine Control
switch in either Run/Idle position, LED’s indi-
cate fuel left in tank.
6 Voltage/Amperage Control
Use control to select weld voltage or
amperage. Control may be adjusted while
welding.
For maximum weld output (above 220
Amps), run unit at 3600 rpm. For weld
output below 220 Amps, operate unit at
3000 or 3600 rpm.
With Process switch in any Stick or TIG set-
ting, use control to adjust amperage. With
Process switch in Wire position, use control
to adjust voltage. When a remote voltage/
amperage control is connected to Remote
receptacle RC4, control sets the maximum
amperage in Stick and TIG modes, but has
no effect in MIG mode.

6-2. Description Of Engine Controls (See Section 6-1)
Engine Control Switch
Use switch to start engine, select speed, and
stop engine. Use switch in combination with
Engine Speed Control switch to select en-
gine speed.
In Run/Idle 3600/2400 RPM position, engine
runs at 2400 rpm no weld load and 3600 rpm
under weld load.
In Run/Idle 3000/1800 RPM position, engine
runs at 1800 rpm no weld load and 3000 rpm
under weld load.
In either position, engine speed is deter-
mined by weld load and position of Engine
Speed Control switch.
Generator power is available at recep-
tacles RC1 and RC2 only at 1800 rpm.
If generator is not locked at 1800 rpm,
engine speed increases in response to
weld load and generator power output
stops at receptacles RC1 and RC2.
Generator power load does not affect
engine speed.
Engine Choke Control
Use control to change engine air-fuel mix
when starting engine.
To Start: pull out choke and turn Engine
Control switch to Start position. Release
switch and slowly push choke in when
engine starts.
With Speed Control switch in Weld, the
engine starts at 3000 rpm and remains there
for two minutes. Engine speed then reduces
to 2000 rpm.
The engine speed reduces from 3000 rpm to
2000 rpm when the Speed Control switch is
toggled within the first two minutes of
operation and no load is applied.
When an auxiliary power load is applied to 60
Hz receptacle RC1 or RC2, engine speed
reduces to 1800 rpm.
If the engine does not start, let the
engine come to a complete stop before
attempting restart.
During cold weather some gasoline en-
gines encounter difficulties that are easi-
ly remedied. See Section 6-3 and 8-7.
To Stop: turn Engine Control switch to Off
position.
Engine Speed Control Switch
Use switch to control engine auto idle func-
tion. Place switch in Generator Lock position
when not welding to lock engine speed at
1800 rpm for generator power at 60 Hz ac re-
ceptacles RC1 and RC2 (generator power is
always available at 60120 Hz receptacle
RC3. See Section 7-2.)
Place switch in Weld position to allow engine
speeds to be determined by position of En-
gine Control switch. The Speed Control
switch is not needed at startup.
6-3. Cold Weather Engine Operation
Ref. 216 172
1 Engine Control Switch
Carburetor Icing
Carburetor icing causes the unit to drop below the normal idle speed and then stall.
This condition occurs when the temperature is near freezing and the relative humid-
ity is high. Ice forms on the throttle plate and inner bore of the carburetor. The engine
typically restarts without problems but soon stalls again.
Treat gasoline with a fuel deicer product (isopropyl alcohol).
Place the Engine Control switch in the Run position.
Run engine only when expecting to frequently load it.
Breather Icing
Oil breather/pulse line icing occurs in severe cold (continuously below 0F). Mois-
ture accumulates in the oil from piston ring blowby if the engine is extensively idled.
This may cause vacuum line freezing, oil breather tube freezing or ice in the carbure-
tor. All of these cause operating problems. Due to ice in the lines, the engine may
not restart until it is warmed to above freezing.
Load engine and reduce idle times to prevent engine shutdowns.
Use an electric fuel pump to avoid pulse line freezing.
Install engine coldweather kit.
Kohler offers a kit for cold weather operation. Contact engine manufacturer for kit
information (1-800-544-2444). The user can install these kits. The kit pulls heated
air from the muffler surface into the carburetor and shuts the cold air off. This in-
creases engine temperature during operation in both idle and high speed.
When the ambient temperatures become warmer (above 45_F) the air flow will
have to be returned to normal.

1 Process Switch
!Weld output terminals are energized
when Process switch is in an Elec-
trode Hot position and the engine is
running.
The unit will not return to idle speed
when Process switch is in a Wire or TIG
position and the remote contactor is on
(closure between pins A and B on re-
mote receptacle).
Use switch to select weld process (see
table below and Section 5-7).
Wire Position:
Use Wire position for MIG welding using a
voltage sensing wire feeder.
Stick Positions:
Use Stick positions for stick (SMAW) and
air carbon arc (CAC-A) cutting and
gouging.
When switch is in a Stick mode, select one
of four dig settings to provide additional am-
perage during short arc length conditions
and help prevent electrodes from “sticking”.
See Stick position descriptions following
(reading L to R):
Soft Arc (E 7018) (Position 1) - This setting
provides a low dig/arc force setting for
smooth weld performance. A stable weld
puddle with little arc “snap” gives excellent
weld bead appearance with minimal
spatter.
Medium Soft Arc (Position 2) - This setting
provides a low to medium dig/arc force that
gives a slightly more fluid weld puddle,
more arc “snap”, and reduces the potential
for electrode sticking at shorter arc lengths.
Medium Stiff Arc (Position 3) - This setting
provides medium dig/arc force for open root
vertical up joints or joints that do not require
additional current for fit up inconsistencies.
Stiff Arc (E6010) (Position 4) - This setting
provides a high dig/arc force for open root
vertical down joints where additional
current is needed to compensate for tight
joint fit up without the need to increase
overall welding current. This setting is rec-
ommended for those who prefer a very stiff
arc with 6010 electrodes.
The dig circuit is disabled when switch is in
Wire or TIG positions.
TIG Position:
Electrode Hot Lift-Arc/Scratch Start TIG
(Provides great DC starts with either start-
ing method) - With switch in this position,
normal open-circuit voltage is not present
between the electrode and workpiece. A
solid-state contactor energizes after the
electrode touches the workpiece,
preventing overheating, sticking, or con-
tamination of the electrode (see Sections
6-6 and 6-7).

6-6. Stick Start Procedure Scratch Start Technique
With Stick selected, start arc as
follows:
1 Electrode
2 Workpiece
3 Arc
Drag electrode across workpiece like
striking a match; lift electrode slightly
after touching work. If arc goes out
electrode was lifted to high. If
electrode sticks to workpiece, use a
quick twist to free it.

6-7. TIG Lift-Arc Start Procedure
Select Lift-Arc/Scratch Start TIG at
Process switch to achieve great arc
starts with either procedure. Perform
Lift-Arc starting method as follows:
Lift-Arc TIG
1 TIG Electrode
2 Workpiece
Turn gas on. Touch tungsten
electrode to workpiece at weld start
point. Hold electrode to workpiece
for 1 second, and slowly lift electrode.
Arc is started when electrode is lifted.
Normal open-circuit voltage is not
present before tungsten electrode
touches workpiece; only a low sensing
voltage is present between electrode
and workpiece. The solid-state output
contactor does not energize until after
electrode is touching workpiece. This
allows electrode to touch workpiece
without overheating, sticking, or
getting contaminated.
Application:
Lift-Arc is used for the DCEN GTAW
process when HF Start method is not
permitted.

6-8. Remote Voltage/Amperage Control
1 Remote Receptacle RC4
Connect optional remote voltage/
amperage (V/A) control to RC4 (see
Section 5-7).
With remote control connected, weld
output in a CC mode (Stick, TIG) is
determined by a combination of front
panel and remote control voltage/
amperage settings. In CV mode
(Wire), weld output is controlled
through remote control only.
2 Remote Hand Control

11-4. How Much Power Does Equipment Require?
S-0623
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 approxi-
mately six times more power while
starting the motor than when running
(see Section 11-8).
3 Rating Data
Rating shows volts and amperes, or
watts required to run equipment.
Amperes x Volts = Watts
Example 1: If a drill uses 4.5 am-
peres at 115 volts, calculate its run-
ning power requirement in watts.
4.5 A x 115 V = 520 W
The load applied by the drill is 520
watts.
Example 2: If three 200 watt flood
lamps are used with the drill from Ex-
ample 1, add the individual loads to
calculate total load.
(3 x 200W) + 520 W = 1120 W
The total load applied by the three
flood lamps and drill is 1120 watts.

4 Motor Voltage
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
motors running amperage.
(kVA/HP x HP x 1000) / Volts =
Starting Amperage
Example: Calculate starting amper-
age required for a 230 V, 1/4 HP mo-
tor with a motor start code of M.
Volts = 230, HP = 1/4, kVA/HP =
11.2
(11.2 x 1/4 x 1000) / 230 = 12.2A

11-9. How Much Power Can Generator Supply?
Ref. ST-800 396-A / S-0625
1 Limit Load To 90% Of
Generator Output
Always start non-resistive (motor)
loads in order from largest to small-
est, 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.

!Have only qualified persons
perform these connections
according to all applicable
codes and safety practices.
!Properly install and ground
this equipment according to
its Owners Manual and na-
tional, state, and local codes.
Customer-supplied equipment
is required if generator will sup-
ply standby power during
emergencies or power out-
ages.
1 Utility Electrical Service
2 Transfer Switch (Double-Throw)
Switch transfers the electrical load
from electric utility service to the
generator. Transfer load back to
electric utility when service is re-
stored.
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 wir-
ing 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 volt-
age and frequency.
5 Essential Loads
Generator output may not meet the
electrical requirements of the prem-
ises. If generator does not produce
enough output to meet all require-
ments, connect only essential
loads (pumps, freezers, heaters,
etc. See Section 11-4).
