This statement appears where the information must be followed

to avoid minor personal injury or damage to this equipment.

KEEP YOUR HEAD OUT OF THE FUMES.

DON’T get too close to the arc.

se corrective lenses if necessary

to stay a reasonable distance

away from the arc.

READ and obey the Safety Data

Sheet (SDS) and the warning label

that appears on all containers of

welding materials.

USE ENOUGH VENTILATION or

exhaust at the arc, or both, to

keep the fumes and gases from

your breathing zone and the general area.

IN A LARGE ROOM OR OUTDOORS, natural ventilation may be

adequate if you keep your head out of the fumes (See below).

USE NATURAL DRAFTS or fans to keep the fumes away

from your face.

If you de velop unusual symptoms, see your supervisor.

Perhaps the welding atmosphere and ventilation system

should be checked.

WEAR CORRECT EYE, EAR &

BODY PROTECTION

PROTECT your eyes and face with welding helmet

properly fitted and with proper grade of filter plate

(See ANSI Z49.1).

E205 is available from the Lincoln Electric Company,

22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

BE SURE THAT ALL INSTALLATION, OPERATION,

MAINTENANCE AND REPAIR PROCEDURES ARE

PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE POWERED

EQUIPMENT.

1.a. Turn the engine off before troubleshooting

and maintenance work unless the

maintenance work requires it to be running.

1.b. Operate engines in open, well-ventilated

areas or vent the engine exhaust fumes outdoors.

1.c. Do not add the fuel near an open flame

welding arc or when the engine is running.

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.

1.d. Keep all equipment safety guards, covers

and devices in position and in good repair.

Keep hands, hair, clothing and tools away

from V-belts, gears, fans and all other

moving parts when starting, operating or

repairing equipment.

1.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

heir removal is complete. Always use the greatest care when

working near moving parts.

1.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.

1.g. To prevent accidentally starting gasoline engines while turning

the engine or welding generator during maintenance work,

disconnect the spark plug wires, distributor cap or magneto wire

as appropriate.

1.h. To avoid scalding, do not remove the radiator

pressure cap when the engine is

hot.

ELECTRIC AND

MAGNETIC FIELDS MAY

BE DANGEROUS

2.a. Electric current flowing through any conductor

causes localized Electric and Magnetic Fields (EMF).

Welding current creates EMF fields around welding cables

and welding machines

2.b. EMF fields may interfere with some pacemakers, and

welders having a pacemaker should consult their physician

before welding.

2.c. Exposure to EMF fields in welding may have other health effects

which are now not known.

2.d. All welders should use the following procedures in order to

minimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Secure

them with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.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.

2.d.4. Connect the work cable to the workpiece as close as pos-

sible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

Safety 02 of 04 - 06/15/2016

ELECTRIC SHOCK

CAN KILL.

3.a. The electrode and work (or ground) circuits are

electrically “hot” when the welder is on. Do

not touch these “hot” parts with your bare skin or wet clothing.

Wear dry, hole-free gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.

Make certain the insulation is large enough to cover your full area

f physical contact with work and ground.

In addition to the normal safety precautions, if

welding must be performed under electrically

hazardous conditions (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, if there

is a high risk of unavoidable or accidental contact

with the workpiece or ground) use the following

equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,

electrode reel, welding head, nozzle or semiautomatic welding

gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical

connection with the metal being welded. The connection should

be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical (earth)

ground.

3.f. Maintain the electrode holder, work clamp, welding cable and

welding machine in good, safe operating condition. Replace

damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrode

holders connected to two welders because voltage

between the

two can be the total of the open circuit voltage of both

welders.

3.i. When working above floor level, use a safety belt to protect

yourself from a fall should you get a shock.

3.j. Also see It ems 6.c. and 8.

ARC RAYS CAN BURN.

4.a. Use a shield with the proper filter and cover plates to protect your

eyes from sparks and the rays of the arc when welding or

observing open arc welding. Headshield and filter lens should

conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant material

to protect your skin and that of your helpers from the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammable

screening and/or warn them not to watch the arc nor expose

themselves to the arc rays or to hot spatter or metal.

FUMES AND GASES

CAN BE DANGEROUS.

5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing these fumes and gases.

When welding, keep your head out of the fume. Use enough

ventilation and/or exhaust at the arc to keep fumes and gases

away from the breathing zone. When welding hardfacing

(see instructions on container or SDS) or on lead

or cadmium plated steel and other metals or

coatings which produce highly toxic fumes, keep

exposure as low as possible and within applicable

OSHA PEL and ACGIH TLV limits using local

exhaust or mechanical ventilation unless exposure

assessments indicate otherwise. In confined

spaces or in some circumstances, outdoors, a

respirator may also be required. Additional

precautions are also required when welding

on galvanized steel.

5. b. The operation of welding fume control equipment is affected by

various factors including proper use and positioning of the

equipment, maintenance of the equipment and the specific

welding procedure and application involved. Worker exposure

level should be checked upon installation and periodically

thereafter to be certain it is within applicable OSHA PEL and

ACGIH TLV limits.

5.c. Do not weld in locations near chlorinated hydrocarbon vapors

coming from degreasing, cleaning or spraying operations. The

heat and rays of the arc can react with solvent vapors to form

phosgene, a highly toxic gas, and other irritating products.

5.d. Shielding gases used for arc welding can displace air and

cause

injury or death. Always use enough ventilation, especially in

confined areas, to insure breathing air is safe.

5.e. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the

Safety Data Sheet (SDS) and follow your employer’s safety

practices. SDS forms are available from your welding

distributor or from the manufacturer.

5.f. Also see item 1.b.

SAFETY

Safety 03 of 04 - 06/15/2016

WELDING AND CUTTING

SPARKS CAN CAUSE

FIRE OR EXPLOSION.

6.a. Remove fire hazards from the welding area. If

this is not possible, cover them to prevent the welding sparks

rom starting a fire. Remember that welding 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.

6.b. Where compressed gases are to be used at the job site, special

precautions should be used to prevent hazardous situations.

Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)

and the operating information for the equipment being used.

6.c. When not welding, make certain no part of the electrode circuit is

touching the work or ground. Accidental contact can cause

overheating and create a fire hazard.

6.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).

6.e. Vent hollow castings or containers before heating, cutting or

welding. They may explode.

6.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 ear plugs

when welding out of position or in confined places. Always wear

safety glasses with side shields when in a welding area.

6.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.h. Also see item 1.c.

6.I. Read and follow NFPA 51B “Standard for Fire Prevention During

Welding, Cutting and Other Hot Work”, available from NFPA, 1

Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.

6.j. Do not use a welding power source for pipe thawing.

CYLINDER MAY EXPLODE IF

DAMAGED.

7.a. Use only compressed gas cylinders containing

the correct shielding gas for the process used

and properly operating regulators designed for

the gas and pressure used. All hoses, fittings,

tc. should be suitable for the application and

maintained in good condition.

7.b. Always keep cylinders in an upright position securely chained to

an undercarriage or fixed support.

7.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.

7.d. Never allow the electrode, electrode holder or any other

electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet

when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand tight

except when the cylinder is in use or connected for use.

7.g. Read and follow the instructions on compressed gas cylinders,

associated equipment, and CGA publication P-l, “Precautions for

Safe Handling of Compressed Gases in Cylinders,” available from

the Compressed Gas Association, 14501 George Carter Way

Chantilly, VA 20151.

FOR ELECTRICALLY

POWERED EQUIPMENT.

8.a. Turn off input power using the disconnect

switch at the fuse box before working on

the equipment.

8.b. Install equipment in accordance with the U.S. National Electrical

Code, all local codes and the manufacturer’s recommendations.

8.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

SAFETY

PRÉCAUTIONS DE SÛRETÉ

Pour

votre propre protection lire et observer toutes les instructions et les pré-

cautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que

les précautions de sûreté générales suivantes:

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 toujours 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.

b. Faire trés attention de bien s’isoler de la masse quand on soude dans

des endroits humides, ou sur un plancher 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.

c. Maintenir le porte-électrode, la pince de masse, le câble de soudage

et la machine à souder en bon et sûr état defonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour le refroidir.

e. Ne jamais toucher simultanément les parties sous tension 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.

f. Si on utilise la machine à souder comme une source de courant pour

soudage semi-automatique, ces precautions pour le porte-électrode

s’applicuent aussi au pistolet de soudage.

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 enrouler le câble-élec-

trode autour de n’importe quelle partie du corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel, donc:

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 rayonnement de l‘arc.

c. Protéger l’autre personnel travaillant à proximité au soudage à l’aide

d’écrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de l’arc de soudage. Se pro-

téger avec des vêtements de protection libres de l’huile, tels que les gants

en cuir, chemise épaisse, pantalons sans revers, et chaussures mon-

tantes.

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 tout

risque d’incendie dû aux étincelles.

7. Quand on ne soud

e pas, poser la pince à une endroit isolé de la masse. Un

court-circuit accidental peut provoquer un échauffement et un risque d’in-

cendie.

8. S’assurer que la masse est connectée le plus prés possible de la zone de

travail qu’il est pratique de le 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 autres circuits. Cela peut provoquer des

risques d’incendie ou d’echauffement des chaines et des câbles jusqu’à

ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est parti-

culiérement important pour le soudage de tôles galvanisées plombées, ou

cadmiées ou tout autre métal qui produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant d’opérations 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 fortement toxique) ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code

“Code for safety in welding and cutting” CSA Standard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POUR

LES MACHINES À SOUDER À

TRANSFORMATEUR ET À

REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code de l’électricité

et aux recommendations du fabricant. Le dispositif de montage ou la

piece à souder doit être branché à une bonne mise à la terre.

2. Autant que possible, I’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’inter-

rupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

DESIGN FEATURES

ontrol Panel

The welder controls consist of a five step current selector switch

and a “Fine Current Adjustment” rheostat located on the upper

control panel at the exciter end of the machine. The lower control

panel welder is equipped with a “Start” button, an “Ignition”

switch, an “Idler” control switch, and a “Glow Plug” button for

easier cold weather starting.

The lower control panel also contains an engine temperature

gauge, a battery charging fault indicator, an oil pressure gauge, a

fuel / hour / LED indicator gauge, temperature gauge, for auxiliary

power consists of one 20 amp, 120VAC (5-20R) duplex receptacle

with GFCI protection and one 15 amp, 240VAC (6-15R) receptacle,

protected by 2 pole, 15 Amp breaker.

Voltmeter & Ammeter - Easy to read analog meter for volts &

amps located on the upper control panel (only on code 12459)

All Copper Windings - For long life and dependable operation.

Engine Idler - The SA-400I

is equipped with an electronic auto-

matic engine idler. It automatically increases and decreases

engine speed when starting and stopping welding or using auxil-

iary power.

A built-in time delay permits changing electrodes before the

engine slows to its low idle speed. The “Idler” control switch on

the panel locks the idler in high idle position when desired.

Auxiliary Power - 3.0 KVA of nominal 120/240V, 60Hz, AC.

Output voltage is maintained within ± 10% at all loads up to rated

capacity. (See Optional Features Section C for Power Plug Kit.)

GFCI - Protects the 20 amp, 120V duplex receptacle. See the

Maintenance Section for detailed information on testing and

resetting of the GFCI.

120 V DUPLEX RECEPTACLE AND GFCI

A GFCI protects the 120V auxiliary power receptacle.

A GFCI (Ground Fault Circuit Interrupter) is a device to protect

against electric shock should a piece of defective equipment

connected to it develop a ground fault. If this situation should

occur, the GFCI will trip, removing voltage from the output of the

receptacle. If a GFCI is tripped see the MAINTENANCE section for

PRE-OPERATION INSTALLATION

EXHAUST SPARK ARRESTER

Some federal, state or local laws may require that engines be

equipped with exhaust spark arresters when they are operated in

certain locations where unarrested sparks may present a fire

hazard. The standard muffler included with this welder does not

qualify as a spark arrester. When required by local regulations,

a suitable spark arrester must be installed and properly

maintained.

Use of an incorrect arrester may lead to engine damage or

performance loss. Contact the engine manufacturer for

specific recommendations.

LOCATION / VENTILATION

Always operate the welder with the doors closed. Leaving the

doors open changes the designed air flow and may cause

overheating.

The welder should be located to provide an unrestricted flow of

clean, cool air. Also, locate the welder so that engine exhaust

fumes are properly vented to an outside area.

This equipment is for industrial use only and it is not intended for

use in residential locations where the electrical power is

provided by the public low-voltage supply system. There can be

potential difficulties in residential locations due to conducted as

well as radiated radio-frequency disturbances. The EMC or RF

classification of this equipment is Class A.

Do not attempt to use this equipment until you have

horoughly read the engine manufacturer’s manual supplied

ith your welder. It includes important safety precautions,

detailed engine starting, operating and maintenance

instructions, and parts lists.

MACHINE GROUNDING

According to the United States National Electrical Code, the

frame of this portable generator is not required to be grounded

and is permitted to serve as the grounding means for cord

connected equipment plugged into its receptacle.

Some state, local, or other codes or unusual operating

circumstances may require the machine frame to be grounded.

It is recommended that you determine the extent to which such

requirements may apply to your particular situation and follow

them explicitly. A machine grounding stud marked with the

symbol is provided on the welding generator frame foot. In

general, if the machine is to be grounded, it should be connected

with a #8 or larger copper wire to a solid earth ground such as a

metal water pipe going into the ground for at least ten feet and

having no insulated joints, or to the metal framework of a

building which has been effectively grounded. The U.S. National

Code lists a number of alternate means of grounding electrical

equipment.

ANGLE OF OPERATION

Engines are designed to run in the level condition which is where

the optimum performance is achieved. The maximum angle of

continuous operation is 25º degrees in all directions, 35º

ntermittent (less than 10 minutes continuous) in all directions.

(maximum 60 seconds).

4. Press the Start button. When the engine starts running,

release both buttons. If the engine fails to start in 20

seconds, wait 30 seconds and repeat the above

procedure.

5. Observe the oil pressure. If no pressure shows within

30 seconds, stop the engine and consult the engine

operating manual. To stop the engine, turn the

“IGNITION” switch to “OFF”.

6. If the engine protection warning light comes on during

cranking or after start up, the “IGNITION” switch must

be turned “OFF” to reset the engine protection system.

7. Allow the engine to run at high idle speed for several

minutes to warm the engine. Stop the engine and

recheck the oil level, after allowing sufficient time for

the oil to drain into the pan. If the level is down, fill it to

the full mark again. The engine controls were properly

set at the factory and should require no adjusting when

received.

Do not attempt to use this equipment until you have thor-

ughly read the engine manufacturer’s manual supplied

with your welder. It includes important safety precautions,

detailed engine starting, operating and maintenance

instructions, and parts lists.

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or elec-

trode with skin or wet clothing.

• Insulate yourself from work and ground

• Always wear dry insulating gloves.

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas or vent

exhaust outside.

MOVING PARTS can injure.

• Do not operate with doors open or guards off.

• Stop engine before servicing.

• Keep away from moving parts.

See additional warning information at

the front of this operator’s manual.

OLD WEATHER STARTING:

ith a fully charged battery and the proper weight oil, the engine

should start satisfactorily even down to about -15°F (-26°C), it

maybe desirable to install cold-starting aides.

Note: Extreme cold weather starting may require longer glow

plug operation.

Under NO

conditions should ether or other starting fluids

be used!

HIGH ALTITUDE OPERATION:

The engine will run correctly up to an altitude of 600 meters

(12,000 ft.). If the engine is to be operated permanently at an

altitude above this, the fuel consumption and exhaust emissions

may be excessive.

Contact a Perkins Service Representative for any engine

adjustments that may be required.

STOPPING THE ENGINE

1. Turn the “IGNITION” switch to “OFF”

At the end of each day’s welding, check the crankcase oil level,

drain accumulated dirt and water from the water separator

located on the fuel rail. Refill the fuel tank to minimize moisture

condensation in the tank. Also, running out of fuel tends to draw

dirt into the fuel system.

When hauling the welder between job sites, close the fuel feed

valve on the separator located on the fuel rail.

If the fuel supply is cut off or runs out while the fuel pump is

operating, air may be entrapped in the fuel distribution system. If

this happens, bleeding of the fuel system may be necessary. Use

qualified personnel to do this per the instructions in the

MAINTENANCE section of this manual.

OPERATION

SA-400I

Some arc instability may be experienced with EXX10 electrodes

when trying to operate with long arc techniques at settings at the

lower end of the open circuit voltage range.

DO NOT attempt to set the “Current Range Selector” between the

five points designated on the nameplate.

-----------------------------------------------------------------

These switches have a spring loaded cam which almost elimi-

nates the possibility of setting this switch between the designat-

ed points.

ENGINE BREAK-IN

Lincoln Electric selects high quality, heavy-duty industrial

engines for the portable welding machines we offer. While it is

normal to see a small amount of crankcase oil consumption

during initial operation, excessive oil use, wet stacking (oil or tar

ike substance at the exhaust port), or excessive smoke is not

normal.

Larger machines with a capacity of 350 amperes and higher,

which are operated at low or no-load conditions for extended

periods of time are especially susceptible to the conditions

described above. To accomplish successful engine break-in,

most diesel-powered equipment needs only to be run at a

reasonably heavy load within the rating of the welder for some

period of time during the engine’s early life. However, if the

welder is subjected to extensive light loading, occasional

moderate to heavy loading of the engine may sometimes be

necessary. Caution must be observed in correctly loading a

diesel/generator unit.

1. Connect the welder output studs to a suitable resistive load

bank. Note that any attempt to short the output studs by

connecting the welding leads together, direct shorting of the

output studs, or connecting the output leads to a length of

steel will result in catastrophic damage to the generator and

voids the warranty.

2. Set the welder controls for an output current and voltage

within the welder rating and duty cycle. Note that any

attempt to exceed the welder rating or duty cycle for any

period of time will result in catastrophic damage to the

generator and voids the warranty.

3. Periodically shut off the engine and check the crankcase oil

level.

WELDER OPERATION

DUTY CYCLE

he NEMA output rating of the SA-400I

s 300 amperes at 32

arc volts on a 60% duty cycle (consult Specifications in this

manual for alternate ratings). Duty cycle is based on a ten

minute period; thus, the welder can be loaded at rated output for

ix minutes out of every ten minute period.

CONTROL OF WELDING CURRENT

DO NOT TURN THE “CURRENT RANGE SELECTOR” WHILE

WELDING because the current may arc between the contacts

and damage the switch.

-----------------------------------------------------------------

The “Current Range Selector” provides five overlapping current

ranges. The “Fine Current Adjustment” adjusts the current from

minimum to maximum within each range. Open circuit voltage

is also controlled by the “Fine Current Adjustment” permitting

control of the arc characteristics.

A high open circuit voltage setting provides the soft “buttering”

arc with best resistance to pop-outs preferred for most welding.

To get this characteristic, set the “Current Range Selector” to the

lowest setting that still provides the current you need and set the

“Fine Current Adjustment” near maximum.

For example: to obtain 180 amps and a soft arc, set the

“Current Range Selector” to the 190-120 position and then

adjust the “Fine Current Adjustment” for 180 amps.

When a forceful “digging” arc is required, usually for vertical and

overhead welding, use a higher “Current Range Selector” setting

and lower open circuit voltage.

For example: to obtain 180 amps and a forceful arc, set the

“Current Range Selector” to the 260-170 position and the “Fine

Current Adjustment” setting to get 180 amps.

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or

electrode with skin or wet clothing.

• Insulate yourself from work and ground.

FUMES & GASES can be dangerous.

• Keep your head out of the fumes.

• Use ventilation or exhaust to remove

fumes from breathing zone.

WELDING SPARKS can cause fire or explosion.

• Keep flammable material away.

ARC RAYS can burn.

• Wear eye, ear, and body protection.

AUXILIARY POWER

If GFCI is tripped, See the MAINTENANCE section for detailed

information on testing and resetting the GFCI.

The AC auxiliary power, supplied as a standard, has a rating of

.0 KVA of 120/240 VAC (60 hertz). Set fine current adjustment

at 100 for maximum auxiliary power.

With the 3.0 KVA, 120/240 VAC auxiliary power, one 120V duplex

protected by GFCI and one 240V duplex, grounding type

receptacle with 2 pole, 15 amp circuit breaker.

One 240 VAC European (IEC-309) 16 AMP receptacle is protected

by a 15 AMP 2-pole circuit breaker, that provides 3.0 KVA of

continuous power. Maximum current is 15 AMPs (only on code

12459).

The rating of 3.0 KVA permits a maximum continuous current of

13 amps to be drawn from the 240V duplex receptacle. 20 amps

can be drawn from the 120V duplex receptacle. The total

combined load of all receptacles is not to exceed 3.0 KVA.

An optional power plug kit is available. When this kit is specified,

the customer is supplied with a plug for each receptacle.

IDLER OPERATION

Start the engine with the “Idler” switch in the “High” position.

Allow it to run at high idle speed for several minutes to warm the

engine. See Specifications for operating speeds.

The idler is controlled by the “Idler” toggle switch on the welder

ontrol panel. The switch has two positions as follows:

1. In the “High” position, the idler solenoid deactivates,

nd the engine goes to high idle speed. The speed is con-

trolled by the governor.

2. In the “Auto” / position, the idler operates as fol-

lows:

a. When welding or drawing power for lights or tools (approxi-

mately 100 watts minimum) from the receptacles, the idler

solenoid deactivates and the engine operates at high idle

speed.

b. When welding ceases or the power load is turned off, a pre-

set time delay of about 15 seconds starts. This time delay

cannot be adjusted.

c. If the welding or power load is not re-started before the end

of the time delay, the idler solenoid activates and reduces

the engine to low idle speed.

RESIDUAL CURRENT DEVICE READY (ONLY FOR 12459)

The SA-400I is configured to allow for the addition of a Residual

Current Device (RCD) to protect the 240V Single Phase

Receptacle. The auxiliary power area on the front panel of the

SA-400I has a hole sized and shaped to accept a typical 2-pole

(RCD) along with a protective rubber boot. A cover plate with a

label “RCD Ready” covers the hole and secures a mounting

bracket on the backside of the panel.

NOTE: the RCD should be rated for at least 15 amps. There are

many suppliers of RCDs. Some examples are:

• Allen Bradley, part number 1492-RCD2A40

• Clipsal, part number 4RC225/30

The protective boot can be used on both RCDs & can be

obtained from:

• APM-Hexseal, part number HE-1035

See Section F-3 Diagrams of this Operator’s Manual for

SAFETY PRECAUTIONS

GENERAL INSTRUCTIONS

1. Blow out the welder and controls with an air hose at least

once every two months. In particularly dirty locations, this

cleaning may be necessary once a week. Use low pressure

air to avoid driving dirt into the insulation.

2. Follow the engine service schedule in this manual and the

detailed maintenance and troubleshooting in the engine

manufacturer’s manual.

COOLING SYSTEM

The SA-400I® is equipped with a pressure radiator. Keep the

adiator cap tight to prevent loss of coolant. Clean and flush the

cooling system periodically to prevent clogging the passage and

overheating the engine. When antifreeze is needed, always use

the permanent type.

BEARINGS

This welder is equipped with a double synthetic sealed ball

bearing having sufficient grease to last indefinitely under normal

service.

COMMUTATOR AND BRUSHES

Uncovered rotating equipment can be dangerous. Use care

so your hands, hair, clothing or tools do not catch in the

rotating parts. Protect yourself from particles that may be

thrown out by the rotating armature when stoning the com-

mutator.

Shifting of the commutator brushes may result in:

- Change in machine output

- Commutator damage

- Excessive brush wear

Periodically inspect the commutator, slip rings, and brushes by

removing the covers. DO NOT remove or replace these covers

while the machine is running. Commutators and slip rings

require little attention. However, if they are black or appear

uneven, have them cleaned by an experienced maintenance man

using fine sandpaper or a commutator stone. Never use emery

cloth or paper for this purpose.

IDLER MAINTENANCE

Before doing electrical work on the idler printed circuit

board, disconnect the battery.

-----------------------------------------------------------------

When installing a new battery or using a jumper battery to start

the engine, be sure the battery polarity is connected properly.

The correct polarity is negative ground. Damage to the engine

alternator and the printed circuit board can result from incorrect

connection.

1. Proper operation of the idler requires good grounding of the

printed circuit board, reed switch, and battery.

2. Idler solenoid is activated for low idle.

3. If desired, the welder can be used without automatic idling by

setting the “Idler” switch to the “High” position.

Have qualified personnel do the maintenance work. Turn

the engine off before working inside the machine. In some

ases, 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 great-

est care when working near moving parts.

Do not put your hands near the engine cooling blower fan.

If a problem cannot be corrected by following the instruc-

tions, take the machine to the nearest Lincoln Field

Service Shop.

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or elec-

trode with skin or wet clothing.

• Insulate yourself from work and ground

• Always wear dry insulating gloves.
