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.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
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.
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:
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 with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) 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. In confined spaces or in some circum-
stances, outdoors, a respirator may be required.
Additional precautions are also required when welding
on galvanized steel.
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.
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 spe-
cific 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.
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.
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 prod-
ucts.
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 Items 6.c. and 8.
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
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.

the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
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.
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.
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.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
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).
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
1235 Jefferson Davis Highway, Arlington, VA 22202.
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.
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
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 cir-
cuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
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

SAFETY
5. Toujours porter des lunettes de sécurité dans la zone de
PRÉCAuTIONS DE SÛRETÉ
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
Pour votre propre protection lire et observer toutes les instruc-
tions et les précautions de sûreté specifiques qui parraissent
dans ce manuel aussi bien que les précautions de sûreté
générales suivantes:
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
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.
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 lev-
age, 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.
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.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
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.
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 forte-
ment toxique) ou autres produits irritants.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à soud-
er 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.
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.
2. Dans le cas de travail au dessus du niveau du sol, se pro-
téger contre les chutes dans le cas ou on recoit un choc. Ne
jamais enrouler le câble-électrode autour de n’importe quelle
partie du corps.

LES MAChINES À SOuDER À
TRANSFORMATEuR ET À
REDRESSEuR
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.
1. Relier à la terre le chassis du poste conformement au code
de l’électricité et aux recommendations du fabricant. Le dis-
positif de montage ou la piece à souder doit être branché à
une bonne mise à la terre.
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-inflamma-
bles.
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’interrupteur à la boite de fusibles.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection
libres de l’huile, tels que les gants en cuir, chemise épaisse,
pantalons sans revers, et chaussures montantes.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

up the thermal Light and Fan will turn on for approxi-
mately 3 seconds.
5. hOT START - Controls the amount of starting ener-
gy in CC Stick (SMAW). The Hot Start can be either
turned on or off. When on, it provides a striking current at
260% of the set current or 275A whichever is larger then
quickly reverts to the set current in 0.4 second.
2. OuTPuT CONTROL - This controls the output
current. Control is provided over the entire output range
of the power source with (1) turn of the control knob. This
control may be adjusted while under load to change
power source output. When using remote control this
function becomes the limit setting.
6. ARC FORCE - This control functions in CC Stick
(SMAW) modes to adjust the Arc Force. The arc is
soft at the minimum settings and more forceful or
driving at the maximum settings. Higher spatter
levels may be present at the maximum settings.
Full range is from -10(Soft) to +10(Crisp)

OPERATION
7. OuTPuT TERMINALS - These quick discon-
nect terminals are compatible with TWECO®* con-
nectors. The terminal provide connection points for
the electrode and work cables. Refer to Output
Connection in the Installation chapter for proper
cable sizes. For positive polarity welding connect
the electrode cable to the positive terminal and the
work cable to the negative terminal. To weld nega-
tive polarity reverse the electrode and work cables.
Note: The short circuit current is limited to 20 amps to
aid in touch starting. Panel output control
becomes the current limit setting when in
remote control.
*Note: Operating this machine with the output control
set to maximum may cause the machine to
phase back and the arc to go out. This occurs
because the welding current exceeded 300
amps and the machine’s protection circuitry
activated. Turn the output control down to cor-
rect this condition.
* TWECO® is registered trademark of Thermo Dyne Corporation.
8. ThERMAL ShuTDOWN INDICATOR -
This light will illuminate if an internal thermostat
has been activated. Machine output will return after
the internal components have returned to a normal
operating temperature. See Thermal Protection
later in this Operation chapter.
PARALLEL OPERATION
The Invertec’s are operable in parallel. For best
results, the currents of each machine should be rea-
sonably well shared. As an example, with two
machines set up in parallel for a 300 amp procedure,
each machine should be set to deliver approximately
150 amps, not 200 amps from one and 100 amps
from the other. This will minimize nuisance feedback
conditions. In general, more than two machines in par-
allel will not be effective due to the voltage require-
ments of procedures in that power range.
9. 3-PIN REMOTE RECEPTACLE
3-Pin remote control allows for remote control of
the Output current.
10. POWER LIGhT - This Light will illuminate
when the power switch is in the “ON” Position.
CONSTANT CuRRENT PROCESSES
To set machine outputs, start with output control pots
and arc force pots in identical positions. Adjust out-
puts and arc forces to maintain current sharing while
establishing the proper output current.
STICK WELDING*
The Invertec may be utilized as a manual DC arc
welder with the electrode cable, work cable, and elec-
trode holder being the only equipment required.
AIR CARbON ARC CuTTING*
Air carbon arc cutting may be performed with the
Invertec within its output rating using 3/16”(4.8mm)
diameter carbon rods. Output cables, an air carbon
arc electrode cable assembly, and a source of com-
pressed air are required.
TIG WELDING*
The ES 275i is capable of touch start TIG welding. An
electrode cable, work cable, TIG torch, and gas sup-
ply with regulator are required.
Touch starting is done as follows:
1. Place the shield cup edge on the work piece.
2. Rock the tungsten down to touch.
3. Gently rock back the tungsten from the work-
piece.

OPERATION
OVERLOAD PROTECTION
The machine is electrically protected from producing
high output currents. Should the output current
exceed 300A, an electronic protection circuit will
reduce the current to less than 200A. The machine
will continue to produce this low current until the pro-
tection circuit is reset. Reset occurs when the output
load is removed.
Note: When TIG welding with the Output Knob at or
above 275 Amps the Arc may go out.
ThERMAL PROTECTION
Thermostats protect the machine from excessive
operating temperatures. Excessive temperatures may
be caused by a lack of cooling air or operating the
machine beyond the duty cycle and output rating. If
excessive operating temperature should occur, the
thermostats will prevent output voltage or current.
Thermostats are self-resetting once the machine cools
sufficiently.
FAN
The cooling fan on the ES 275i operates once 15
amps of welding current is drawn and for 7 minutes
after the output current has stopped flowing.
The fan will also run anytime the machine has over
heated.
POWER-uP SEQuENCE
At power up the thermal light (and Power light on
codes 11164 and above) turns on and the fans run for
approximately 3 seconds. This is the pre-charge time
for the main capacitors. After this time the fans and
thermal light turn off and the pre-charge relay closes
to apply full line power to the capacitors. At this time
the machine is ready to weld.

•Heat sink fins
•Input Filter Capacitors
•Output Terminals
4. Examine capacitors for leakage or oozing. Replace
if needed.
5. Examine the sheet metal case for dents or break-
age. Repair the case as required. Keep the case in
good condition to ensure that high voltage parts are
protected and correct spacings are maintained. All
external sheet metal screws must be in place to
assure case strength and electrical ground continu-
ity.
6. Check electrical ground continuity. Using an ohm-
meter, measure resistance between either output
terminal and an unpainted surface of the machine
case. (See Figure D.2 for locations.) Meter reading
should be 500,000 ohms or more. If meter reading
is less than 500,000 ohms, check for electrical com-
ponents that are not properly insulated from the
case. Correct insulation if needed.
7. Replace machine cover and screws.

_______________________________
CAuTION: Sometimes machine failures
appear to be due to PC board failures. These
problems can sometimes be traced to poor
electrical connections. To avoid problems
when troubleshooting and replacing PC
boards, please use the following procedure:
- If you return a P.C. Board for credit, it must
be in the static-shielding bag. This will prevent
further damage and allow proper failure analy-
sis.
4. Test the machine to determine if the fail-
ure symptom has been corrected by the
replacement PC board.
1. Determine to the best of your technical
ability that the PC board is the most likely
component causing the failure symptom.
NOTE: It is desirable to have a spare (known
good) PC board available for PC board trou-
bleshooting.
2. Check for loose connections at the PC
board to assure that the PC board is prop-
erly connected.
NOTE: Allow the machine to heat up so that
all electrical components can reach their oper-
ating temperature.
3. If the problem persists, replace the sus-
pect PC board using standard practices to
avoid static electrical damage and electri-
cal shock. Read the warning inside the
static resistant bag and perform the follow-
ing procedures:
5. Remove the replacement PC board and
substitute it with the original PC board to
recreate the original problem.
a. If the original problem does not reap-
pear by substituting the original
board, then the PC board was not the
problem. Continue to look for bad
connections in the control wiring har-
ness, junction blocks, and terminal
strips.
P.C. board can be dam-
aged by static electricity.
- Remove your body’s stat-
ic charge before opening
the static-shielding bag.
Wear an anti-static wrist
strap. For safety, use a 1
Meg ohm resistive cord
connected to a grounded
part of the equipment
frame.
ATTENTION
Static-Sensitive
Devices

and test the machine.
Reusable
Container
Do Not Destroy
- If you don’t have a wrist
strap, touch an unpainted,
grounded, part of the
equipment frame. Keep touching the frame to
prevent static build-up. Be sure not to touch
any electrically live parts at the same time.
6. Always indicate that this procedure was
followed when warranty reports are to be
submitted.
NOTE: Following this procedure and writing on the
warranty report, “INSTALLED AND SWITCHED PC
