SECTION 3
3.0 INSTALLATION
1. Mount the WC-9 Coolant Circulator in a convenient location near the torch.
Allow for free circulation of air through the grated panels of the cooler.
2. Connect the torch coolant inlet hose to the "coolant supply to torch" fitting. If
necessary, use one or more 12-1/2-ft. hose extensions (P/N 40V76) and hose
couplings (P/N 11N18).
3. Torch coolant outlet hoses are normally terminated in a power cable adaptor,
fuse assembly, flow switch or connection block which is threaded to mate with
a 12-1/2-ft. drain hose, P/N 40V76. Using one or more lengths of hose (and
11N18 couplings as needed), connect the coolant return line from the torch to
the fitting labelled "coolant return from torch".
4. Remove the two (2) screws from the front of the hinged top cover and flip back.
Remove filler cap and fill reservoir with torch coolant. Lubricant additives to the
coolant are not required and are not recommended.
NOTE: Due to the high electrical conductivity, use of tap water or commer-
cial antifreeze is NOT recommended for torch cooling. A specially
formulated torch coolant, P/N 156F05 (1 gal. container) is available
and recommended for torch cooling. The coolant also provides
antifreezes protection down to -34
NOTE: Operating the unit without coolant will cause permanent damage to
pump.
5. Connect the input power cord of the WC-9 to the proper voltage and frequency
power source. Operate the unit only at the voltage and frequency stamped on
the nameplate, unless converted for 115VAC use.
6. Run the WC-9 long enough to pump coolant through the system. Add more
coolant to the tank to make up for portion used to fill the system. The coolant
level indicator will appear dark when coolant is at a safe level. Add coolant
when indicator appears clear.
7. As shipped, the unit is set to deliver coolant at 50 psi. If more or less pressure
is desired, a pressure adjustment screw is located under the small acorn nut
on the pump. To increase pressure, turn screw clockwise; to decrease, turn
screw counterclockwise. Make sure service hoses are suitable for higher
pressures.
IMPORTANT: The motor must run continuously. Never connect the WC-9
to a power supply or wire feeder with solenoid valve opera-
tion where the motor will start and stop with each operation
of the welding contactor. The cooling efficiency of the unit
will be hampered and the starting winding in the motor may
burn out.
