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 disconnect
fittings. The COOL ARC ® 55 is a continuous duty cooler.
The COOL ARC ® 55 is very easy to use and understand with only
one power switch on the control panel. The cooler has a stan-
dard 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 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.
