Dear Customer,
THANKS! You had a choice, and you bought an Everlast. We appreciate you as a custom-
er and hope that you will enjoy years of use from your welder.
Please go directly to the Everlast website to register your unit and receive your warranty information.
Your unit registration is important should any information such as product updates or recalls be is-
sued. It is also important so that we may track your satisfaction with Everlast products and services.
If you are unable to register by website, contact Everlast directly through the sales department
through the main customer service number in your country. Your unit will be registered and warran-
ty will be issued and in full effect. Keep all information regarding your purchase. In the event of a
problem, as a rst step, you must contact technical support before your welder can be a candidate
for diagnosis and warranty service. The unit cannot be returned for repair until authorization is
given by technical support. Units returned without contacting tech support and attaching an au-
thorization repair form may incur repair charges and/or denial of claim. The reason you must rst
contact technical support is because it allows proper diagnoses and can remedy many issues over
the phone, preventing needless delays and returns.
Please review the current online warranty statement and information found on the website
of the Everlast division located in or nearest to your country. Print it for your records and
become familiar of its terms and conditions.
Everlast offers full technical support, in several different forms. We have online support available
through email, and a welding support forum designed for customers and noncustomer interaction.
Technical advisors are active on the forum daily. We also divide our support into two divisions: tech-
nical and welding performance. Should you have an issue or question concerning your unit, please
contact performance/technical support available through the main company headquarters available in
your country. For best service call the appropriate support line and follow up with an email, particu-
larly if off hours, or you cannot reach a live person. In the event you do not reach a live person, par-
ticularly during heavy call volume times, holidays, and off hours, leave a message and your call will
normally be returned within 24 hours. Also for quick answers to your basic questions, join the com-
pany owned forum available through the website. You’ll nd knowledgeable, helpful people and staff
available to answer your questions, and perhaps nd a topic that already addresses your question at
http://www.everlastgenerators.com/forums/.
Should you need to call or write, always know your model name, purchase date and welder manu-
facturing inspection date. This will assure the quick and accurate customer service.
REMEMBER: Be as specic and informed as possible. Technical and performance advisors rely
upon you to carefully describe the conditions and circumstances of your problem or question.
Take notes of any issues as best you can. You may be asked many questions by the advisors to
clarify problems or issues that may seem very basic. However, diagnosis procedures MUST be
followed to begin the warranty process. Advisors can’t assume anything, even with experienced
users, and must cover all aspects to properly diagnose the problem. Depending upon your issue,
it is advisable to have basic tools handy such as screwdrivers, wrenches, pliers, and even an inex-
pensive test meter with volt/ohm functions before you call.
Let us know how we may be of service to you should you have any questions.
Sincerely,
Everlast Customer Service

Everlast is dedicated to providing you with the best possible equipment and service to meet the
rigorous welding demands that you have. We want to go beyond merely delivering a satisfacto-
ry product to you. We want to offer products that meet and exceed expectations, in both per-
formance and service. That is the reason we offer free technical support to assist you with your
needs and questions should the occasion occur. With proper use and care your product should
deliver years of trouble free service. Safe operation is a partial key to achieving long life and
optimum performance from your unit.
Any product designed to meet safety standards can be operated in an unsafe manner. No
amount of safety apparatuses can ultimately prevent accidents in every situation if the product is
used in an unsafe manner. Ultimately, safe operation and proper maintenance is your responsi-
bility. Safe operation also requires the operator to have basic welding knowledge and practice
common sense and caution during use.
We have compiled this operator’s manual, to instruct you in basic safety, operation and mainte-
nance of your Everlast product to give you the best possible experience. Much of welding and
cutting is based upon experience and common sense. As thorough as this welding manual may
be, it is no substitute for either. Exercise extreme caution and care in all activities related to
welding or cutting. Your safety, health and even life depends upon it. While accidents are never
planned, preventing an accident requires careful planning.
Please read this manual carefully before you operate your Everlast unit. The purpose of this
manual is not only to instruct the operator in the basic use of the machine, but also to assist
the operator in obtaining the best performance from the unit Do not operate the unit until you
have read this manual and you are thoroughly familiar with the safe operation of the unit. If you
feel you need more information please contact Everlast technical or welding support.
The warranty does not cover improper use, maintenance or consumables. Do not attempt to
alter or defeat any piece or part of your unit, particularly any safety device. Keep all shields
and covers in place during unit operation should an unlikely failure of internal components result
in the possible presence of sparks and explosions. If a failure occurs, discontinue further use
until malfunctioning parts or accessories have been repaired or replaced by qualied personnel.
Note on High Frequency electromagnetic disturbances:
Certain welding and cutting processes generate High Frequency (HF) waves. These waves may
disturb sensitive electronic equipment such as televisions, radios, computers, cell phones, and
related equipment. High Frequency may also interfere with fluorescent lights. Consult with an
electrician if disturbance is noted. Sometimes, improper wire routing or poor shielding may be
the cause.
HF can interfere with pacemakers. See EMF warnings in following safety section for further in-
formation. Always consult your physician before entering an area known to have welding or
cutting equipment if you have a pacemaker.
Safety Precautions

6
These safety precautions are for protection of safety and health. Failure to fol-
low these guidelines may result in serious injury or death. Be careful to read
and follow all cautions and warnings. Protect yourself and others.
Welding and cutting processes produce high levels of ultraviolet (UV) radiation that can
cause severe skin burn and damage. There are other potential hazards involved with welding
such as severe burns and respiratory related illnesses. Therefore observe the following to
minimize potential accidents and injury:
Use appropriate safety glasses with wrap around shields while in the work area, even under
welding helmets to protect your eyes from flying sparks and debris. When chipping slag or
grinding, goggles and face shields may be required.
When welding or cutting, always use an approved shielding device, with the correct shade
of lter installed. Always use a welding helmet in good condition. Discard any broken or
cracked lters or helmets. Using broken or cracked lters or helmets can cause severe eye
injury and burn. Filter shades of no less than shade 5 for cutting and no less than shade 9 for
welding are highly recommended. Shades greater than 9 may be required for high amperage
welds. Keep lter lenses clean and clear for maximum visibility. It is also advisable to consult
with your eye doctor should you wear contacts for corrective vision before you wear them
while welding.
Do not allow personnel to watch or observe the welding or cutting operation unless fully
protected by a lter screen, protective curtains or equivalent protective equipment. If no
protection is available, exclude them from the work area. Even brief exposure to the rays
from the welding arc can damage unprotected eyes. If necessary, use a welding screen.
Always wear hearing protection because welding and cutting can be extremely noisy. Ear
protection is necessary to prevent hearing loss. Even prolonged low levels of noise has been
known to create long term hearing damage. Hearing protection also further protects against
hot sparks and debris from entering the ear canal and doing harm.
Always wear personal protective clothing. Flame proof clothing is required at all times.
Sparks and hot metal can lodge in pockets, hems and cuffs. Make sure loose clothing is
tucked in neatly. Leather aprons and jackets are recommended. Suitable welding jackets and
coats made from re proof material may be purchased from welding supply stores. Discard
any burned or frayed clothing. Keep clothing away from oil, grease and flammable liquids.
Leather boots or steel toed leather boots with rubber bottoms are required for adequate foot
protection. Canvas, polyester and other man made materials often found in shoes will either
burn or melt. Rubber or other non conductive soles are necessary to help protect from elec-
trical shock.
Flame proof and insulated gauntlet gloves are required whether welding or cutting or han-
dling metal. Simple work gloves for the garden or chore work are not sufcient. Gauntlet
type welding gloves are available from your local welding supply companies. Never attempt to
weld with out gloves. Welding with out gloves can result in serious burns and electrical
shock. If your hand or body parts comes into contact with the arc of a plasma cutter or weld-
er, instant and serious burns will occur. Proper hand protection is required at all times when
working with welding or cutting machines!
Safety Precautions

7
WARNING! Persons with pacemakers should not weld, cut or be in the welding area until
they consult with their physician. Some pacemakers are sensitive to EMF radiation and
could severely malfunction while welding or while being in the vicinity of someone welding.
Serious injury or death may occur!
Welding and plasma cutting processes generate electro-magnetic elds and radiation. While
the effects of EMF radiation are not known, it is suspected that there may be some harm from
long term exposure to electromagnetic elds. Therefore, certain precautions should be taken
to minimize exposure:
• Lay welding leads and lines neatly away from the body.
• Never coil cables around the body.
• Secure cables with tape if necessary to keep from the body.
• Keep all cables and leads on the same side the body.
• Never stand between cables or leads.
• Keep as far away from the power source (welder) as possible while welding.
• Never stand between the ground clamp and the torch.
• Keep the ground clamp grounded as close to the weld or cut as possible.
Welding and cutting processes pose certain inhalation risks. Be sure to follow any guidelines
from your chosen consumable and electrode suppliers regarding possible need for respiratory
equipment while welding or cutting. Always weld with adequate ventilation. Never weld in
closed rooms or conned spaces. Fumes and gases released while welding or cutting may be
poisonous. Take precautions at all times.
Any burning of the eyes, nose or throat are signs that you need to increase ventilation.
• Stop immediately and relocate work if necessary until adequate ventilation is obtained.
• Stop work completely and seek medical help if irritation and discomfort persists.
WARNING! Do not weld on galvanized steel, stainless steel, beryllium, titanium, copper, cadmi-
um, lead or zinc without proper respiratory equipment and /or ventilation.
WARNING! This product may contain products known to the State of California to cause birth
defects and in some cases cancer and/or reproductive harm. The use of this product may cre-
ate by-products with the same effects. (California Safety and Health Code §25249.5 et seq.,
Prop. 65)
WARNING! Do not weld or cut around Chlorinated solvents or degreasing areas. Release of
Phosgene gas can be deadly. Consider all chemicals to have potential deadly results if welded
on or near metal containing residual amounts of chemicals.
Keep all cylinders upright and chained to a wall or appropriate holding pen. Certain regula-
tions regarding high pressure cylinders can be obtained from OSHA or local regulatory agency.
Consult also with your welding supply company in your area for further recommendations. The
regulatory changes are frequent so keep informed.
All cylinders have a potential explosion hazard. When not in use, keep capped and closed.
Store chained so that overturn is not likely. Transporting cylinders incorrectly can lead to an
explosion. Do not attempt to adapt regulators to t cylinders. Do not use faulty regulators. Do
not allow cylinders to come into contact with work piece or work. Do not weld or strike arcs on
cylinders. Keep cylinders away from direct heat, flame and sparks.
Safety Precautions

8
WARNING! Electrical shock can kill. Make sure all electrical equipment is properly grounded.
Do not use frayed, cut or otherwise damaged cables and leads. Do not stand, lean or rest on
ground clamp. Do not stand in water or damp areas while welding or cutting. Keep work sur-
face dry. Do not use welder or plasma cutter in the rain or in extremely humid conditions.
Use dry rubber soled shoes and dry gloves when welding or cutting to insulate against electri-
cal shock. Turn machine on or off only with gloved hand. Keep all parts of the body insulated
from work, and work tables. Keep away from direct contact with skin against work. If tight
or close quarters necessitates standing or resting on work piece, insulate with dry boards and
rubber mats designed to insulate the body from direct contact.
CAUTION! All work cables, leads, and hoses pose trip hazards. Be aware of their location and
make sure all personnel in area are advised of their location. Taping or securing cables with
appropriate restraints can help reduce trips and falls.
WARNING! Fire and explosions are real risks while welding or cutting. Always keep re extin-
guishers close by and additionally a water hose or bucket of sand. Periodically check work
area for smoldering embers or smoke. It is a good idea to have someone help watch for possi-
ble res while you are welding. Sparks and hot metal may travel a long distance. They may go
into cracks in walls and floors and start a re that would not be immediately visible. Here are
some things you can do to reduce the possibility of re or explosion:
• Keep all combustible materials including rags and spare clothing away from area.
• Keep all flammable fuels and liquids stored separately from work area.
• Visually inspect work area when job is completed for the slightest traces of smoke or em-
bers.
• If welding or cutting outside, make sure you are in a cleared off area, free from dry tender
and debris that might start a forest or grass re.
• Do not weld on tanks, drums or barrels that are closed, pressurized or anything that held
flammable liquid or material.
CAUTION! Metal is hot after welding or cutting! Always use gloves and or tongs when handling
hot pieces of metal. Remember to place hot metal on re-proof surfaces after handling. Seri-
ous burns and injury can result if material is improperly handled.
WARNING! Faulty or poorly maintained equipment can cause injury or death. Proper mainte-
nance is your responsibility. Make sure all equipment is properly maintained and serviced by
qualied personnel. Do not abuse or misuse equipment.
Keep all covers in place. A faulty machine may shoot sparks or may have exploding parts.
Touching uncovered parts inside machine can cause discharge of high amounts of electricity.
Do not allow employees to operate poorly serviced equipment. Always check condition of
equipment thoroughly before start up. Disconnect unit from power source before any service
attempt is made and for long term storage or electrical storms.
Further information can be obtained from The American Welding Society (AWS) that relates
directly to safe welding and plasma cutting. Additionally, your local welding supply company
may have additional pamphlets available concerning their products. Do not operate machin-
ery until your are comfortable with proper operation and are able to assume inherent risks of
cutting or welding.

This manual has been compiled to give an overview
of operation and is designed to offer information cen-
tered around safe, practical use of the water cooler.
Only YOU, the operator, can ensure that safe operating
practices are followed, through the exercise of com-
mon sense and training. Do not operate this machine
until you have fully read the manual.
1. To ensure that your Everlast Power Cool 400 is
in top condition, carefully inspect it for damage
upon opening arrival, looking for damage on the
surface of the unit and to the cooler itself and all
its accessories. Note: A very small amount of
residual water from testing may still be present in
the tank, or may have leaked from the tank. Re-
move the box and plastic and fully check the unit
immediately upon receipt of product. Any damage
issues must be resolved right away through tech
support. The product should also be tested at the
same time for proper operation, even if it is to be
stored for a while. Check to make sure all passag-
es, connections and ttings are clear of any pack-
ing material or other obstruction. Failure to test
and check the unit may result in denial of shipping
damage and warranty claims. Record the serial
number on the page provided in this manual. In-
clude purchase date for warranty reference. Serial
numbers are located on the top, side or rear of
the machine, wherever the specication sticker is
located (may vary). Be sure to register your unit
online as well. Please locate, download and read
your current warranty statement found online at
www.everlastgenerators.com listed under “terms
and policy”.
2. The Power Cool 400 is designed for industrial
fabrication and repair chores. Overall function
and design has been geared toward simple, trou-
ble free operation. The units offers fast and easy
connection of the TIG or MIG torch. The connect-
ors are 9mm quick connect male couplings availa-
ble from Everlast and many other sources found
in welding stores and online sources.
3. The unit should be lled only with distilled water
or with an approved antifreeze that is rated for
TIG/MIG water cooler use (ethylene glycol). The
antifreeze designed for TIG/MIG use has algae
growth preventers which keep the small passages
in a TIG or MIG torch clear. Use of automotive-
type antifreeze can cause other long term damage
to the cooler. It also creates an electrically con-
ductive circuit which can make starting the arc
difcult while the HF start is in use. Some water
cooler coolants are listed as “MIG Only”. Be sure
to evaluate the claims of the product before pur-
chase and use. The warranty does not cover
freezing, clogging or corrosion of components due
to improper antifreeze. Do not use MIG only rated
coolant if it is to be used with TIG or poor arc
starting may result.
4. The unit should be stored in a dry place for long
term storage and drained of coolant. Humid/wet
conditions can contribute to the eventual decay of
the circuitry in the machine. For safety reasons,
do not use this machine directly in the rain or with
soaked clothing or damp protective gear. The ser-
vice rating for this unit is IP21, sufcient for drip-
ping water protection, but is not recommended for
wet environment use.
5. Make sure that the cooling fan and exhaust vents
are kept free of obstruction. Before every opera-
tion, inspect the unit for unexpected obstructions.
From time-to-time (at least quarterly) cleaning of
the machine with low pressure air and a small
plastic bristle brush will be necessary to ensure
long life and efcient cooling. On these occasions
only, unplug the water cooler and remove the main
cover to access the interior. Do not remove the
front panel. A dirty or blocked radiator will lower
the cooling capability because it reduces the air
flow and heat exchanging capability of the unit.
Keep a minimum of 12 inches distance from any
obstruction on the front, rear and sides of the
unit during operation. If the unit does not seem
to spin up and run normally, turn off the unit im-
mediately. Then, unplug the cooler. Remove the
top cover and inspect the fan and radiator. Make
sure the radiator has not shifted into the fan during
shipping. If the fan is clear from obstruction, turn
it gently and make sure the fan/pump assembly
spins smoothly and freely. If it does not, contact
tech support immediately. In any case, where the
fan does no seem to start or spin properly, imme-
diately turn the unit off.
6. The cooler is designed to run continuously while
it is switched on. The cooler flow is not activated
by the foot pedal or torch switch. Flow through
the torch should be continuous. Failing to turn
the unit on while welding with a water-cooled
torch can result in damage to the TIG torch. The
receptacle found on the rear of your Everlast weld-
er is designed to be used with the PowerCool 400
cooler. Power will flow to the plug when the weld-
er is switched on. If the cooler switch is left
switched in the on position, the welder will turn the
cooler on and off as the power is cycled.
7. This unit is 220/240 V only. Do not use it with
110/120 V circuits! If this cooler is to be used with
units other than Everlast TIG machines tted with
the IEC 60320-1 c-13/14 setup, the plug must be
removed and a new one installed. Consult a li-
censed electrician and local electrical codes be-
fore attempting any modication of the wiring of
the water cooler or power circuit.
8. Refer to the following pages for specications.
Note that product specications are subject to
change without notice due to product improve-
ments. If any additional information is needed
contact Everlast. As with any product, some
changes in specications do occur that do not af-
fect overall scope and function of the machine.

“Water Flow Out” goes to the separate water line (cooled water) from the torch. Usually these are color
coded, but in cases where color code does not agree or is not coded, ignore color coding and attach the
DINSE type power connector side of the torch to the “Water Flow IN” side. If you cannot determine
which hose to connect to the “Water Flow Out” side, leave the hoses disconnected and simply blow air
through the DINSE type connector side (Water Flow IN) to determine gas destination points. The line that
conducts air through is the “Water Flow Out” side. The remaining line is the gas line to the torch.

2.1 Basic Features. The Everlast PowerCool 400 is rated for
400 amps of cooling for either TIG or MIG welders. It is de-
signed to be stacked with the PowerTIG 315LX, PowerTIG
350EXT, and the PowerMTS 252STi, and Lightning 275. It will
work with all machines in the Everlast lineup equipped with a
rear Power Plug, but modications will be required to the top
rails and will require the end user to ret and make the neces-
sary adjustments.
1. Water Flow In (Red): The hot water returns from the TIG
torch through this connection. You can identify the return
(hot) connection on by identifying the line that comes
directly from the main power block/ Dinse-style connect-
or. The quick connect ttings which are standard 9mm
quick connect ttings found commonly on MIG water-
cooled torches and some TIG torches. Contact Everlast
should you need additional male connectors to t your
torch. The unit comes with additional line extensions
and adapters to be used in helping extend the leads and
adapt other brand torches. If an additional connector or
adapter is needed, contact Everlast.
2. Water Flow Out (Blue): The cool water comes from the
water cooler and goes to the TIG torch directly to the
handle and the head. You can identify the cool water
connection by gently blowing compressed air through the
line attached to the DINSE type connector (the return line
to the cooler). The water flow out line will be the one with
air flowing out of it. The remaining line is the gas line to
the torch. The quick connect ttings which are standard
9mm quick connect ttings found commonly on MIG
water-cooled torches and some TIG torches. Contact
Everlast should you need additional male connectors to
t your torch. The unit comes with additional line exten-
sions and adapters to be used in helping extend the
leads and adapt other brand torches. If an additional
connector or adapter is needed, contact Everlast.
3. Coolant Fill Cap. The removeable cap removes to allow
the unit to be lled with Coolant. Although the mouth is
wide enough to allow pouring of coolant, use a funnel
when lling to avoid spills. Clean up any spills as soon as
possible.
4. Coolant Drain Cap. Use this cap to evacuate the coolant
from the coolant reservoir when changing or renewing
coolant. Some residual coolant may remain in the reser-
voir and cooler lines and pump.
5. Coolant Reservoir. The coolant reservoir holds approxi-
mately 7.5 Liters of coolant. This does not fully account
for the entire systems contents that are stored in the
radiator, pump, cooler lines of the unit. Allow another .5
to 1 liter to completely ll the tank and torch, depending
upon length. Do not allow the coolant to drop below the
5L mark while in operation. Only ll with distilled or de-
ionized water (for temperate areas only where freezing
does not occur), or with coolant specically designed for
TIG and or MIG welders (use in any climate). These type
of coolants have algaecides and lubricants needed for TIG
use. DO NOT USE AUTOMOTIVE TYPE COOLANT. USE
WITH A COOLANT WITH AN ETHEYLENE GLYCOL BASE.
IF USING FOR TIG, DO NOT USE A COOLANT FOR RATED
ONLY FOR MIG OPERATION.
6. Mounting Rail. The two mounting rails located on top of
the unit are used to couple the units listed above in sec-
tion 2.1 to the cooler. This allows the units to sit securely
on top of the water cooler without sliding or moving. This
connection interfaces with the rails mounted to the bot-
tom of the welders designed to interface with this welder.
The rails will not prevent separation completely, but will
keep the unit in place under normal operating conditions.
When used with the available cart for these models, it
holds the unit securely in place. If being used without the
recommended Everlast cart/cooler/welder system, be sure
to arrange a way to semi-permanently fasten the welders
together through attaching a separate bracket to the sides.
Special Note For the MTS 252STi: This cooler will nest
with the unit, but repositioning of one of the rails may be
necessary for the rails to match up. In that case, remove
the rail screws and use the alternate holes provided in the
cover to reattach the rails. If no holes are provided in
your cooler for alternate reattachment, remove the cover
of the cooler, and drill new holes into the cover in a posi-
tion that matches the foot print of the PowerMTS 252STi.
This will not affect warranty. Do not drill holes with the
cover attached!
7. 220/240 V Plug and cable. Most versions (unless special-
ly ordered) use the IEC 60320-1 C-13/14 plug/recepctacle
combination commonly found on computer power sup-
plies. This allows the unit to be specially coupled to the
Everlast Welder. This plug is found on most TIG or Multi-
Process units in the Everlast line 200 amps and over.
(Excluding the Power i-TIG 200 and 201 models and other
DC Only model welders, or DC welder/cutters). The use of
this plug prevents confusion with other type connections
and prevent accidental 120V operation. If the unit must
be rewired, keep in mind this is a 240 V only unit. Consult
a licensed electrician and local codes before proceeding
with any electrical modication to the water cooler or to
the electrical power supply circuit.
8. On/Off switch. This switch is a lighted switch to remind
the operator that the water cooler is on. If the water
cooler won’t come on or the switch will not light, contact
Everlast. Some versions may not use the lighted switch
feature.
Operation Notes:
1. Priming: After the cooler is lled for the rst time, make sure
there are no leaks and water is flowing correctly. It may take
some time to fully prime. Leave the return line loose and flowing
into the ller neck. If the cooler does not prime, contact Everlast
for proper bleeding procedures. (See next page for more details)
2. Regular Maintenance: After running the cooler coupled to the
TIG torch for 30 minutes, check the water cooler for dripping
water or leaks. If leaks are suspected, remove the top cover and
tighten the water clamps that are connecting the water lines to
the reservoir. Periodically keep the unit checked for leaks. Peri-
odically, unplug the unit and remove the cover to clean radiator
and fan blades and cooling ns with compressed air.
3. WARNING: Anytime the cover is removed, the unit MUST be
unplugged. Do not operate the water cooler with the cover off.
There are moving parts inside that can inflict severe injury, result-
ing in severe cuts, lacerations or loss of limb. There are electrical
parts inside that can shock or electrocute you.
4. WARNING: Do not operate the water cooler if leaks are present.
Electrocution, or severe injury may result! Check and tighten
ttings. Contact Everlast if new ttings or lines are needed.
5. IMPORTANT: Use only distilled water, ethylene glycol, or ap-
proved TIG/MIG water cooler coolant. Do not use automotive Anti-
freeze.
6. CAUTION: Always make sure cooler is on and water is circulating
before welding with a water cooled torch or damage to the torch
will result.
7. CAUTION: Parts of this water cooler may become extremely hot!
Use extreme caution when handling the cooler during and after
use.
8. CAUTION: Operate the unit with at least 12” clearance on all sides
or the cooler may not be effective and may overheat.

IMPORTANT:
This unit may need to be primed before use. Before attempting to weld, allow the return line
from the torch to be left loose and drain directly into the reservoir (with the cap removed). The
torch should otherwise be connected normally. Fill the unit. Allow 4-5 minutes for the coolant
to settle. Turn the unit on with the line still draining directly into the top of the reservoir. Allow
up to 5 minutes with the unit running to prime. If stored for long periods of time, always check
to see if the cooler is still primed. If the unit does not prime, contact Everlast for alternate prim-
ing methods. Do not run the cooler for more than 5 minutes while trying to prime the pump
Doing so may overheat the components and damage the cooler. Welding with a water-cooled
torch that has air pockets trapped may prevent proper cooling and damage the torch.
INFORMATIONAL NOTE: At the factory, the unit has been lled, tested and reviewed for proper
operation. The coolant has subsequently been drained. But on occasion there is a residual
amount of water which may remain in the lines. During shipping, some of this water may nd
its way into the packaging. This small amount is harmless and is normal and should not be of
concern. If the unit is extremely wet or concerns exist, open the cooler by removing the green
metal cover and allow to dry.
OPERATIONAL NOTE: Although this unit is switched to allow on/off operation, the unit may be
left in the “ON” position if using with an Everlast Welder. The main power switch on the welder
will control power to the outlet and will serve as a master switch for both the welder and the
cooler. However, always verify the cooler has come on when the power is switched on at the
master switch and the fan is turning.
OPERATIONAL NOTE: Periodically service your coolant, especially if you are using distilled wa-
ter or deionized water. Coolant can grow algae or become contaminated with normal sediment
that occurs through normal wear-in of the unit. This can block the torch passages, and even
cause the unit to loose its prime. Problems created by use of unauthorized types of coolants
can compound this issue. Issues related to wrong coolant, improper maintenance will void the
warranty.
OPERATIONAL NOTE: Periodically check tightness of cooler ttings. This will require removal
of the cover of the cooler. To avoid injury, always unplug the cooler rst! Removing the cover
for maintenance and does not void the warranty. To the contrary, it is expected and required to
properly maintain your cooler.
