Lincoln Electric IM10134 COOL ARC 55 S WATER COOLER - Manual (Page 12)

B-1 OPERATION B-1
POWER-UP SEQUENCE
The COOL ARC ® 55 S will be powered up at the same
time as the power source. The status light will blink
green for about a minute while the system is configuring.
After this time, the status lights will turn a steady green
indicating the machine is ready.
The pump and fan in the COOL ARC ® 55 S will run only
when welding begins, or while holding the switch on the
front of the unit.
RECOMMENDED PROCESSES AND
EQUIPMENT
The COOL ARC ® 55 S is designed for use with water-
cooled TIG, MIG, PAC (Plasma Arc Cutting) and PAW
(Plasma Arc Welding) guns and torches. The COOL
ARC
® 55 S can be used with MIG wire feeders and S
series power sources.
COMMON EQUIPMENT PACKAGES

K2823-3 POWER WAVE ® S350
K2230-1 POWER FEED ® 10M
K1543-XX ArcLink ® CABLE (5 PIN ) - connects
wire feeder to cooler.
TURNING THE SYSTEM "ON"
After connecting the COOL ARC ® 55 S per the instal-
lation 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.
Although the cooler is designed to turn on/off as need-
ed while welding, for initial setup and when installing a
new gun you will first need to fill the system with
coolant. This can be done by using the momentary
switch on the front of the unit. Remove the fill cap and
hold the switch down until you see coolant return into
the tank. The system is now primed and ready for use.
You will be able to hear the fan running and feel air-
flow out of the sides of the unit when the cooler is
operating.

SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Do not operate with covers removed.
• Do not operate if cables are wet or
immersed in water.
• Moving parts can injure. Never place
fingers into openings of Cooler.
• 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.

PRODUCT DESCRIPTION
The COOL ARC ® 55 S is a re-circulation cooling sys-
tem designed for use with water-cooled TIG, MIG,
PAC (Plasma Arc Cutting) and PAW (Plasma Arc
Welding) guns and torches. The COOL ARC
® 55 S is
designed for use with S series power sources and
requires 115 VAC power input and an ArcLink
® con-
nection. The cooler will communicate via ArcLink ®
with the wire feeder and power source to automatical-
ly turn on when welding is taking place, and off a few
minutes after welding.
The COOL ARC ® 55 S is equipped with a flow sensor
to only allow welding to occur when coolant is flowing.
When a low or no flow condition is sensed, welding
will be shut down to protect valuable torches and
guns.
Adding coolant to the reservoir is simple and connect-
ing to the coolant "IN" and "OUT" connections are
easily made by hand with the quick disconnects.
The COOL ARC ® 55 S 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 sup-
ply from the coolant reservoir and delivers coolant to
the welding torch or gun. Refer to Figure B.1 and
B.2.
