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.

pressure used. All hoses, fittings, etc. 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.  
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  
Electrical Code and the manufacturer’s recommendations.  
6.h. Also see item 1.c.

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.

the output will be energized in STICK (SMAW) mode and  
TIG (GTAW) if the remote is set to local control. At power  
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)  
3. LOCAL/REMOTE SWITCh - Place in the  
“LOCAL” position to allow output adjustment at the  
machine. Place in the “REMOTE” position to allow output  
adjustment at remote pot or amptrol. In Remote, the  
machine output control pot is the limit setting for remote  
control.

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.

MAINTENANCE  
ROuTINEꢀMAINTENANCE  
1. Perform the following preventive maintenance pro-  
cedures at least once every six months. It is good  
practice to keep a preventive maintenance record;  
a record tag attached to the machine works best.  
2. Remove the machine wrap-around cover and per-  
form the input filter capacitor discharge procedure  
(detail at the beginning of this chapter).  
3. Keeping the machine clean will result in cooler  
operation and higher reliability. Be sure to clean the  
following areas with a low pressure air stream. See  
figure D.2 for component locations.  
•Power and control printed circuit boards  
•Power switch  
•Main transformer  
•Input rectifier  
•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

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
