SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

• Disconnect input power by remov- ing plug from receptacle before working inside Cooler.

•Use only grounded receptacle.

•Do not remove the power cord ground prong.

•Do not touch electrically “hot” parts inside Cooler.

•Have qualified personnel do the installation, main- tenance and troubleshooting work.

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 thrust- ing sharp objects through the carton liner, which may puncture the plastic reservoir. Below is the recom- mended 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 sup- plied 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 glycol (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 pas- sageways 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 sub- stances are virtually impossible to purge from the water lines and heat exchanger.

To avoid freeze damage and water leakage in ship- ment, 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 mid- dle of the unit. Remove the fill cap by pressing 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 opening 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. towels) wetted with ethylene glycol are toxic to humans and animals. They must not be haphazardly discarded, especially by pouring liquids down the drain. Contact the local EPA office for responsible dis- posal 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 rec- ommended coolants.

CAUTION

DO NOT USE OIL BASED COOLANTS OR COOLANTS THAT CONTAIN RUST INHIBITORS OR LEAK STOP- PERS.

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

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 forward 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.
