SAFETY PRECAUTIONS
UNPACKING THE COOL ARC
®
40
The packaging of the Cooler is designed to withstand shipping
abuse, and contains a cardboard liner that surrounds the unit. If
any shipping damage has occurred, contact your certified
Lincoln distributor or service center. When unpacking the unit,
avoid thrusting sharp objects through the carton liner, which
may puncture the plastic reservoir. Below is the recommended
procedure for unpacking the Cooler:
• Open top flap where identification label appears.
• Remove loose items and top insert.
• Open bottom flap.
• Remove bottom insert and slide Cooler, wrapped in inside
liner from outer carton.
• Gently remove liner and packaging foam from Cooler. Save
the instruction manual and service directory supplied with the
COOL ARC
® 40 for parts orders and future maintenance
service.
FILLING THE COOLANT RESERVOIR:
Recommended Coolant
• For Use Above Freezing: Clean tap, distilled or de-ionized
water.
• For Use Below Freezing: 50% water and 50% pure ethylene
glyco (reagent or industrial grade) mixture.
• DO NOT USE: Automotive anti-freeze that contains rust
inhibitors or leak stoppers.
These coolants will damage the pump and block the small
internal passageways of the heat exchanger, affecting cooling
performance.
• DO NOT USE: Pre-packaged welding industry coolants.
These coolants may contain oil-based substances, which
attack the plastic components of the cooler. Once added to
the cooler, these substances are virtually impossible to purge
from the water lines and heat exchanger.
To avoid freeze damage and water leakage in shipment, the
COOL ARC
® 40 unit is delivered empty with no coolant in the
system. To fill the unit, locate the plastic Snap-On reservoir fill
cap at the front middle of the unit. Remove the fill cap by press-
ing the center of the cap inward while pulling at the tab on the
outer edge.
Clean tap water, distilled water, de-ionized water, a 50/50 mix of
pure ethylene glycol and water, or any other coolant specified
by the manufacturer of the water cooled product that the Cooler
is used with, can be added into the coolant reservoir. The open-
ing of the fill cap mates with most coolant containers but, to
avoid spillage of coolant, a funnel should be placed into the
reservoir hole when filling the COOL ARC
® 40.
NOTE: Pure solutions and mixtures of, or materials (i.e. tow-
els) wetted with ethylene glycol are toxic to humans and ani-
mals. They must not be haphazardly discarded, especially by
pouring liquids down the drain. Contact the local EPA office for
responsible disposal methods or for recycling information.
For best results when using the COOL ARC ® 40 with Lincoln
guns or torches, use distilled or de-ionized water, although if not
available, tap water can be used. If protection from freezing is
desired, use a 50% water and 50% pure ethylene glycol
(reagent or industrial grade) mixture. An alcohol and water mix-
ture is also acceptable.
When using the COOL ARC ® 40 with other products, consult
the manufacturer's instruction manual for recommended
coolants.
D
DO NOT USE OIL BASED COOLANTS OR COOLANTS
THAT CONTAIN RUST INHIBITORS OR LEAK STOPPERS.

The unit can be filled either vertically or horizontally.
UNPLUG THE COOLER BEFORE FILLING THE COOLANT
RESERVOIR:
UPRIGHT (VERTICAL):
• Tilt the unit backward and pour 2 gallons (7.6 liters) of coolant
into the coolant reservoir fill hole through a funnel.
• If a 1 gallon (3.8 liters) fill bottle is available, tilt the unit for-
ward until the bottle mates with the coolant reservoir fill hole.
Then tilt the unit backward until the fill bottle is emptied. Fill the
unit with 2 gallons (7.6 liters) of coolant.
ELECTRIC SHOCK can kill.
• Only qualified persons should perform
this installation.
HOT COOLANT CAN BURN SKIN
• Always be sure coolant is not hot before
doing any work on cooler parts.
ROTATING FAN BLADES ARE
HAZARDOUS
• Do not put your hands near operating fan.
• 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.
• 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 their removal is complete.
Always use the greatest care when working near mov-
ing parts.
