Lincoln Electric IM696 COOL ARC 40 STAND ALONE - Manual (Page 12)

B-1 OPERATION B-1
PRODUCT DESCRIPTION
The COOL ARC ® 40 is a stand alone re-circulation
cooling system designed for use with water-cooled
TIG, MIG, PAC (Plasma Arc Cutting) and PAW
(Plasma Arc Welding) guns and torches. The coolant
"IN" and "OUT" connections are 5/8-18 left-hand
female threads which match the standard connector
nut of domestic water hoses (CGA style) and water-
cooled TIG torches. The COOL ARC
® 40 is a continu-
ous duty cooler.
The overall size and shape of the cooler is identical to
the Magnum 20. The COOL ARC
® 40 can operate in
either the vertical or horizontal position. The COOL
ARC
® 40 is very easy to use and understand with only
one power switch on the control panel. The cooler has
a standard 115 V power input receptacle, making it
very easy to power up. Adding coolant to the reservoir
is simple and connecting to the coolant "IN" and
"OUT" connections are easily made with an adjustable
wrench.
The COOL ARC ® 40 coolant flow is circulated through
a heat exchanger to remove heat energy from the
coolant. The coolant flow is then deposited into the
coolant reservoir. The pump draws its coolant supply
from the coolant reservoir and delivers coolant to the
welding torch or gun. Refer to Figure 6.
RECOMMENDED PROCESSES AND EQUIPMENT
Recommended Processes, Equipment and
Accessories. The COOL ARC
® 40 is designed for use
with water-cooled TIG, MIG, PAC (Plasma Arc
Cutting) and PAW (Plasma Arc Welding) guns and
torches. The COOL ARC
® 40 can be used with MIG
wire feeders and power sources as well as TIG power
sources.
TURNING THE SYSTEM "ON"
After connecting the COOL ARC ® 40 per the installa-
tion instructions above, plug the unit into a 115V
NEMA electrical receptacle for start-up operation. Be
certain that the power input into the unit matches the
Cooler's rated input.
The LIGHTED POWER SWITCH is located on the
right side of the control panel. The cooler will be "ON"
when pressed to " l " and "OFF" when pressed to " O
". The switch will also illuminate when in the "ON"
position.
You will be able to hear the fan running and feel air-
flow out of the back of the unit when the cooler is
operating. The cooler will run continuously unless it is
plugged into a switched receptacle on the power
source.

SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Disconnect input power by
removing plug from receptacle
before working inside Cooler.
• Do not operate with covers
removed.
• 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,
maintenance and troubleshooting work.
• Unplug the cooler before performing general
maintenance without removing drawer.
• 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 and remove water hoses to
remove drawer from the cabinet for mainte-
nance purposes. A jumper hose between the
coolant in and out connections should be
installed to avoid excessive loss of coolant in
the system.
• 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.
• The cooler should be turned "OFF" when weld-
ing is not taking place for long periods of time.
• Be certain that the cooler is "ON" (power switch
in the " l " position) before beginning to weld.
• 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
water lines.
• Keep all water lines clean and free of any block-
age.
• Do not operate cooler without coolant in reser-
voir. Never run pump dry.
