Tools Needed:

5/8 in

To prevent overheating, make sure cooling

unit is positioned so airflow is not restricted.

NOTICE − If welding power source has a

water valve, do not connect hoses to water

valve. Connect hoses as shown.

1 Coolant Out Hose

2 Coolant In Hose

Fittings have 5/8-18 left-hand threads.

Connect hoses with proper fittings as

shown. Some power sources may require

a TIG block.

3 Coolant Tank Cap

4 115 Volt AC Grounded Receptacle

An individual branch circuit capable of car-

rying 15 amperes and protected by fuses

or circuit breakers is recommended. Rec-

ommended fuse or circuit breaker size is

15 amperes.

Operation:

Fill tank with proper coolant. Use table in

Section 7 to select proper coolant. Maintain

coolant level at approximately 1 in (25 mm)

below top of filler neck. Connect hoses as

shown. Unit turns on when plugged in.

fore maintaining.

1 Coolant Filter

Unscrew housing to clean filter.

Changing coolant: Drain coolant by

tipping unit to rear, or use suction

pump. Fill with clean water and run

for 10 minutes. Drain and refill with

coolant (see section 7).

. If replacing hoses, use hoses

compatible with ethylene gly-

col, such as Buna-n, Neo-

prene, or Hypalon. Oxy-acety-

lene hoses are not compatible

with any product containing

ethylene glycol.

Install cover if removed.

12. Troubleshooting

Trouble Remedy

Coolant system does not work. Be sure input power cord is plugged in to energized receptacle.

Check line fuses or circuit breaker, and replace or reset if necessary.

Motor overheated. Unit starts running when motor has cooled.

Have Factory Authorized Service Agent check Power switch S1 and motor (Mot).

Decreased or no coolant flow. Add coolant.

Check for clogged hoses or coolant filter. Clean filter or clean / replace hoses if necessary.

Disconnect pump, and check for sheared coupling. Replace coupling if necessary.
