WC-8C VERTICAL COOLANT CIRCULATOR

P/N 33739 (115/230vac, 50/60Hz) - Vaild Serial No. WxxJ348xxx and above

INSTALLATION

1. Select appropriate input voltage. See Input Voltage sec-

tion.

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 12-

1/2-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 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 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.

Be sure this information reaches the operator. You can

get extra copies through your supplier.

These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation and safe

practices for arc welding equipment, we urge you to read our booklet, "Precautions and Safe Practices for Arc Welding,

Cutting, and Gouging, "Form 52-529. Do NOT permit untrained persons to install, operate, or maintain this equipment.

Do NOT attempt to install or operate this equipment until you have read and fully understand these instructions. If you

do not fully understand these instructions, contact your supplier for further information.

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

water or commercial antifreeze is NOT recom-

mended 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 -34

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 indica-

tor 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 op-

eration 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.

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.

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 win-

dow. 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 protec-

tion. 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, dis-

charge 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.

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 electri-

cal connections and inlet plug must be changed. See Data

Plate located on the motor for electrical connections.
