NOTE: Due to the high electrical conductivity, use of tap

water or commercial 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 antifreeze protection
down to -34o F.

INSTALLATION

1. Select appropriate input voltage. See Input Voltage sec­tion.

2. Mount the WC-8C Coolant Circulator in a convenient
location near the torch. Allow for free circulation of air
through the grated panels of the cooler.

3. Connect the torch coolant inlet hose to the "coolant
supply to torch" tting. If necessary, use one or more 12­1/2-ft. hose extensions (P/N 40V76) and hose couplings
(P/N 11N18).

4. Torch coolant outlet hoses are normally terminated in
a power cable adaptor, fuse assembly, ow switch or
connection block which is threaded to mate with a 12­1/2-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 tting labelled
"coolant return from torch".

5. Remove ller cap and ll tank with approximately 1.5
gallons of torch coolant (156F05). Lubricant additives to
the coolant are not required and are not recommended.
Be sure to ll tank completely.

NOTE: Operating the unit without coolant will cause

permanent damage to pump.

6. Connect the input power cord of the WC-8C to the
proper voltage and frequency power source. Operate
the unit only at the voltage and frequency stamped on
the nameplate, unless converted for 230vac use.

7. Run the WC-8C long enough to pump coolant through
the system. Add more coolant to the tank to make up for
portion used to ll the system. The coolant level indica­tor will appear dark when coolant is at a safe level. Add
coolant when indicator appears clear.

8. 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-8C to a power supply
or wire feeder with solenoid valve op­eration where the motor will start and
stop with each operation of the welding
contactor. The cooling eciency of the
unit will be hampered and the starting
winding in the motor may burn out.

Be sure this information reaches the operator. You can
get extra copies through your supplier.

INPUT VOLTAGE SELECTION

As shipped, the unit is assembled for 115 vac. 50/60 Hz use.
To use with 208-230 vac, 50/60 Hz input, the motor electri­cal connections and inlet plug must be changed. See Data

Plate located on the motor for electrical connections.

MAINTENANCE

ELECTRIC SHOCK CAN KILL. Precautionary measures
should be taken to provide maximum protection against
electrical shock. Be sure that all primary power to the
machine has been externally disconnected. Open wall
disconnect switch or circuit breaker before attempting
inspection or work inside the circulator. Install all covers
after completing service. Do not operate unit without
covers. If this equipment does not operate properly,
stop work immediately and investigate the cause of the
malfunction. Maintenance work must be performed by
an experienced person, and electrical work by a trained
electrician. Do not permit untrained persons to inspect,
clean, or repair this equipment. Use only recommended
replacement parts.

1. Maintain coolant level by observing the indicator win­dow. When dark, coolant is at a safe level; when clear,
add more coolant.

2. Periodically remove the large 15/16" acorn nut from the
pump and check the lter screen (19972) for sediment.
Clean the lter or replace if necessary.

3. Periodically empty and ush the reservoir.

4. To insure optimum performance of the circulator,

remove dust from the radiator by means of compressed

air.

5. The motor is equipped with a thermal overload protec­tion. If motor stops, switch power o and wait at least
5 minutes. Then switch power on. If motor runs, the
motor was shut o by the thermal overload protection.
If it does not run, then check motor for damage.

6. Oil both motor bearings (yellow oil plug) once a year for
heavy usage with SAE 20 oil.

TROUBLESHOOTING

1. Pump Below Capacity - Can be caused by restricted
inlet, wrong direction of rotation, low motor R.P.M., and
the relief valve improperly adjusted.

2. Pump Noisy - Can be caused by restricted inlet, dis­charge pressure over 125 P.S.I., loose acorn nut or
damaged acorn nut gasket, air getting into lines, loose
couplings, misalignment between pump and motor, and
loose mounting bolts or clamping ring.

3. Leakage - Is caused by failing mechanical shaft seal or
rubber O-rings. Arrange to have pump rebuilt.

4. Pump Turns Hard - Can be caused by misalignment be-
tween pump and motor or by lime and mineral deposits
in the pump. Deposits in pump would necessitate a
pump rebuild, arrange to have pump rebuilt.

5. Motor No Turning - Check to see if circuit breaker
tripped. Motor may be overheated. Allow to cool with
power removed from unit for at least 5 minutes.

6. Do not disassemble pump! Any attempt at eld repair
will void the warranty.

If this equipment does not operate properly, stop work
immediately and investigate the cause of the malfunction.
Maintenance work must be performed by an experienced
person, and electrical work by a trained electrician. Do not
permit untrained persons to inspect, clean, or repair this
equipment. Use only recommended replacement parts.
