COOL WAVE™ 20S

OPERATION

SAFETY PRECAUTIONS
Read this entire section of operating instructions
before operating the machine.
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrodes with your skin or wet
clothing.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
FUMES AND GASES can be danger-
ous.
• Keep your head out of fumes.
• Use ventilation or exhaust to remove
fumes from breathing zone.
WELDING SPARKS can cause fire
or explosion.
• Keep flammable material away.
• Do not weld on containers that have held
combustibles.
• Do not cut aluminum over water tables
ARC RAYS can burn.
• Wear eye, ear, and body protection.
The following should always be observed when operating
the Cool Wave™ 20S
• Never operate the cooler with any case parts off or
removed. The drawer must always be slid all the way
into the cabinet and secured with two screws in the
front.
• Unplug the cooler before removing the drawer or
servicing the unit.
• High voltage typical of welding operations can kill.
• Immersion in water around electrical lines can cause
electrical shock.
• Moving parts can injure. Never place fingers into
openings of Cooler.
• Unplug the cooler before filling the reservoir.
• Never operate the cooler with the reservoir fill cap off.
• Hot coolant can burn skin. Always be sure coolant is
NOT HOT before servicing the cooler.
• Do not pour used ethylene glycol coolant down the
drain.
• Do not remove the pump relief valve's 3/4" hex nut or
attempt to adjust the relief valve setting.
Observe additional guidelines detailed in the
beginning of this manual.

TURNING THE SYSTEM "ON"

After connecting the Cool Wave™ 20S per the installation
instructions above, turn on the Power Wave Welder power source.
You should see the LED on the front of the cooler turn green and
you will be able to hear the fan running and feel air ow out of the
side of the unit when the cooler is operating. The cooler will run
when a weld is initiated and for some time afterward.
When first starting the unit, check all of the coolant hoses to
ensure that no coolant leaks are present. Coolant leakage causes
poor cooling performance, potential health and electrical safety
hazards, and will eventually cause the system to shut down.

OPERATING PRECAUTIONS AND WARNINGS

The following should always be observed when operating the
Cool Wave™ 20S:
• Check the coolant reservoir level daily
• Keep the reservoir full especially after changing any
lines/torches
• Never operate the cooler with the reservoir fill cap removed
unless checking coolant flow
• Avoid placing the cooler near areas of extreme heat
• Avoid placing the cooler near a flux hopper or an area where
dust build-up is extreme
• Avoid kinking or putting sharp bends in any coolant lines
• Keep all coolant lines clean and free of any blockage
• Do not attempt to operate cooler without coolant in reservoir
• Do not operate the cooler on an inclined surface greater
than 15° from horizontal.

COOLING EFFICIENCY

The high cooling efficiency of the Cool Wave™ 20S helps to
extend the life of the torch consumables. Heat from the welding
arc is transferred into the coolant and removed via the exiting
air ow at the side of the cooler.
Ambient air temperature affects the cooling performance of the
Cool Wave™ 20S. Maximum coolant temperature is 162°F and
controlled by a thermistor mounted to the radiator inlet.
