MAGNUM COOLER 10-I & 20-I
A-2
PRODUCT DESCRIPTION
Magnum Coolers 10-I and 20-I are stand alone recir-
culating cooling systems designed for use with water
cooled TIG, MIG, PAC (Plasma Arc Cutting) and PAW
(Plasma Arc Welding) guns and torches. Additional
applications include resistance welding, induction
heating and water cooled fixtures such as EDM’s and
small Verti-Shield dams. The connection block located
at the back of the Cooler contains 5/8-18 left hand
female thread. A 5/8-18 left hand nut and matching
nipple are supplied with each Magnum Cooler 10-Iand
Cooler 20-I unit to convert hoses that may have differ-
ent connectors. The international Cooler 10-I and 20-I
are also furnished with a bracket so that the Cooler
can be anchored at the back of a Lincoln K874 double
cylinder undercarriage.
With lower 45 psi (310 kPa) (3.0 bar) output pressure
delivery to increase TIG torch component life,
Magnum Cooler 10-I is made for all water cooled TIG
applications and low to medium duty MIG applica-
tions. The higher 60 psi (410 kPa) (4.0 bar) output
pressure delivery of Magnum Cooler 20-I supports
higher demand water cooled applications without
decreasing component life.
The Magnum Coolers bring new technology in the
areas of pump, heat exchanger and reservoir designs
to the water cooler market. These technologies allow
the Magnum Coolers to be lighter in weight, lower in
energy consumption, mounted either vertically or hori-
zontally, and operated even in the case of a “soft”
pump failure. The unique “soft” pump failure feature
allows some pump stages to continue to pump coolant
even if one or two stages have failed.
The unique “On-Demand” system (when used with a
water valve or solenoid in the system) only pumps
coolant when it is needed, saves energy, reduces
noise and increases pump and fan motor life by turn-
ing off the system between welds.
The Magnum Cooler is capable of operating continu-
ously; however, the "on-demand" feature is strongly
recommended in ALL APPLICATIONS TO ASSURE
GOOD PUMP AND MOTOR LIFE.
Magnum Cooler are easy to service. Removal of the
front case provides access to all internal components.
The Phillips head fasteners used to anchor the casing
of the unit match those of the pump and other internal
component connections. In this manner, an operator
can repair all major components using just a Phillips
head screwdriver.
