INSTALLATION OF WATER COOLED
ACCESSORIES
After following the installation instructions above, the
COOL ARC® 40 is ready for connection to a water-
cooled accessory.
WATER COOLED TIG TORCH AND MIG GUN
Follow Figure 2 when using the COOL ARC® 40 with
water-cooled TIG torches. Follow Figure 4 when using
the COOL ARC® 40 with water-cooled MIG gun.
Consult the manufacturer's instruction manual when
using the COOL ARC® 40 with other water-cooled
TIG and MIG accessories.
CONNECTION TO WIRE FEEDERS
Follow Figure 3 when using the COOL ARC® 40 in
conjunction with a wire feeder. The feeder will need to
have pass-through water hoses installed in order to
correctly function with the COOL ARC® 40, since the
cooler requires continuous flow. DO NOT USE A
WATER SOLENOID VALVE
Water pass-through connection kits are available for
wire feeders. Refer to product literature or the wire
feeder's instructions manual for kit availability and fur-
ther connection details. It is not required to run the
water lines through the wire feeder, but is does pro-
vide a very neat MIG gun connection.If pass-through
water hoses are unavailable, connect the MIG gun as
shown in Figure 4.

CAUTION
DO NOT USE A WATER SOLENOID VALVE with
the COOL ARC® 40. When a solenoid valve clos-
es, the pump would dead-head, causing the pump
to heat up excessively leading to premature failure
of the pump.

K529-10 POWER INPUT CABLE WITH WATER
AND GAS HOSES
This cable assembly includes a (1) power cable, (1)
control cable, (1) gas hose and (2) water hoses to
connect a power source to a wire feeder. The cable
length is 3.05m (10Ft.). The water hoses have 5/8"-18
left hand male hose fittings and the gas hose has a
5/8"-18 right hand male hose fitting. The cable and
hose lengths are designed to connect a wire feeder to
a COOL ARC® 40 that is vertically mounted at the
rear of a power source on a dual cylinder undercar-
riage.
Refer to Figure 5 for an illustration of this connection.
