®
22 is a cooling system designed to work
specifically with Lincoln Electric TIG welding power sources.

LOCATION
This cooler will operate in harsh environments. However, it is
important that preventive measures are followed to assure long
life and reliable operation:
• Do not place or operate this cooler on a surface with an
incline greater than 15° from horizontal.
• The cooler must be located where there is free circulation of
clean air without restrictions for air movement to and from
the air vents. Do not cover the cooler with paper, cloth or rags
when switched on.
• Dirt and dust that can be drawn into the cooler should be kept
to a minimum.
• This cooler has a protection rating of IP23. Keep it dry, shelter
it from rain & snow and do not place it on wet ground or in
puddles.
• Locate the cooler away from radio controlled machinery.
Normal operation may adversely affect the operation of
nearby radio controlled machinery, which may result in injury
or equipment damage. Read the section on regarding Electric
and Electromagnetic Fields in the safety section of the
manual.
• Do not operate in areas with an ambient temperature greater
than 104°F (40°C). Warning: The ambient air temperature
influences the parameters of cooling. If the ambient
temperature is higher, the cooling system will be less
effective.
WARNING
Avoid placing the cooler near a flux hopper or an area where
dust build-up is extreme.
Avoid placing the cooler near areas of extreme heat.
RECOMMENDED POWER SOURCE
The Cool Arc
®
22 is designed for use with water-cooled torches.
®
The Cool Arc
22 must be used with a Lincoln Electric TIG welding
power source that lists the Cool Arc 22 as an approved accessory.
INPUT SUPPLY CONNECTION
The Cool Arc
®
22 must be powered directly from the welding
power sources listed above.
To connect or disconnect the input supply to the Cool Arc
turn off the welding power source and then connect or disconnect
it from the cooler.
Caution must be observed because the input voltage to the cooler
is 390Vdc.
An internal electronic board adapts this voltage for the pump, fan
and light.
WARNING
Welding power sources are equipped with protection,
however, do not connect or disconnect a CA22 to or from a
welding power source that is on. Always turn OFF the
welding power source.
Do not apply power to the welding power source when the
cooler reservoir is insufficiently filled and/or the torch's
hoses are disconnected from the cooling unit. Failure to
observe this warning may cause internal damage to the
cooler.
