RECOMMENDED PROCESSES AND EQUIPMENT
Recommended Processes, Equipment and
Accessories. The COOL ARC
® 55 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 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 ® 55 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 left
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 sides of the unit when the cooler is
operating. The cooler will run continuously unless it is
plugged into a switched receptacle on the power

PRODUCT DESCRIPTION
The COOL ARC ® 55 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 female quick discon-
nect fittings. The COOL ARC
® 55 is a continuous duty
cooler.
The COOL ARC ® 55 is very easy to use and under-
stand with only one power switch on the control panel.
The cooler has a standard 115 V power input recepta-
cle, 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
by hand with the quick disconnects.
The COOL ARC ® 55 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 B.1 and B.2.
