B-1 OPERATION
POWER WAVE WATER COOLER
B-1
SAFETY PRECAUTIONS
GENERAL DESCRIPTION :
The Power Wave Cooler is specifically designed to
work with select Power Wave’s type power sources
for MIG and TIG guns and torches. It mounts directly
underneath the power source to conserve floor space.
Integral to the cooler is a flow switch to protect weld-
ing guns when water flow is interrupted. Electrical
power for the cooler is supplied by the power source.
The following should always be observed when
operating any Power Wave Water Cooler:
• Never operate the G3503-[ ] cooler outside of its
case, or without access door in place.
• Immersion in water around electrical lines can
cause electrical shock.
• Never place fingers into openings of Cooler.
Moving parts can injure.
• Turn off power to the Power Wave or the discon-
nect switch before filling the reservoir.
• Never operate the Cooler with the reservoir fill cap
off. (See Figure 1.A)
OPERATING PRECAUTIONS
The following should always be observed when oper-
ating any Power Wave Water Cooler:
• Check the reservoir daily. (See Figure 3)
• Keep the reservoir full especially after changing any
water lines.
• The power to the Cooler should be turned off when
welding is not taking place for a long period of time.
• Be certain that the Cooler is on (power switch in the
“I” position) before beginning to weld.
• Never operate the Cooler with the reservoir fill cap
removed.
• Avoid placing the Cooler near areas of extreme
heat.
• Avoid placing the Cooler near a flux hopper or an
area where dust build-up is extreme.
• Avoid kinking or putting sharp bends in any water
lines.
• Keep all water lines clean.
TURNING THE SYSTEM ON
After filling the reservoir and connecting the coolant
hoses to the Power Wave Water Cooler per the
Installation Section, turn the Water Cooler on.
You will be able to hear the unit running and feel air
flow out of the front of the K1767-1 when the Cooler is
operating. The Cooler will run continuously when the
Power Wave is turned on.
When first starting the unit, check all of the water lines
to insure that no coolant leaks are present. Leakage
causes poor welding performance, poor cooling per-
formance, low welding component life and potential
electrical safety hazards.
Turn the primer switch on and hold for ten seconds.
coolant will start to flow through the system and the
green LED “Flow on” will light, when the primer switch
is released the pump will remain on and continue to
circulate coolant.
If the flow sensor detects low flow, the pump will stop
operating and the YELLOW LED “Flow Fault” will light.
A signal will be sent to the Power Wave to stop weld-
ing to protect the welding gun or torch. (See Figure
1.a)
Refer to the troubleshooting guide to find the potential
causes of the coolant flow fault.
ELECTRIC SHOCK can kill.
• Disconnect input power by remov-
ing plug from receptacle before
working inside Cooler.
• Do not operate with covers
removed.
• Use only grounded receptacle.
• Do not remove the power cord ground prong.
• Do not touch electrically “hot” parts inside
Cooler.
• Have qualified personnel do the installation,
maintenance and troubleshooting work.
