WATER COOLER USAGE

The Power Wave is equipped with an optional internal water cooler. We recommend using the water cooler when welding above 300 amps with argon blends on a regular basis. The gun heating from pulsing above 300 amps average current is often excessive and leads to reduced consumable life, reduced gun life, and opera- tor discomfort. Water cooling greatly increases the durability of the gun and parts at high current.

There are two water connections on the rear of the Power Wave. See Figure D.1. Connect the water lines between these connectors and those on the wire feed- er. The water is fed through the feeder into the gun.

When a water cooler is used, the water cooler must be enabled by using the Setup Overlay.

The water cooler contains a pressure switch, which is closed when there is adequate pressure in the water cooler hose for normal operation. If this pressure drops below the switch manufacturer’s set point, the pressure switch opens. A couple of seconds after the pressure switch opens the water cooler shuts down. If the water cooler is enabled and the pressure switch opens, the machine beeps loudly indicating that there is a problem with the water cooler operation.

RECOMMENDED COOLANTS

1.The following coolants have been determined to be compatible with the wetted materials used in the

G3503-[ ] cooler assembly:

Distilled or deionized water

Potable tap water

Sediment-free mixtures containing a maxi- mum of 50% ethylene glycol or automotive- grade antifreeze and the balance of distilled or deionized water.

2.Ethylene glycol mixtures should be selected if the cooler may be exposed to a temperature below the freezing point of water.

3.Consult gun, torch, and wire feeder manuals for coolant recommendations and select one from the above list.

4.Pure solutions and mixtures of, or materials (i.e. towels) wetted with ethylene glycol are toxic to humans and animals. They must not be haphazard- ly discarded, especially by pouring liquids down the drain. Contact the local EPA office for responsible disposal methods or for recycling information.

5.The cooler’s reservoir has a nominal liquid capacity of 1.6 gallons.

PRIMING THE COOLER

1.Select a recommended coolant and fill cooler to specified level (see Fig. D.2).

2.Attach desired water-cooled accessory (gun and wire feeder or TIG torch) to cooler’s QDs.

3.Prime the cooler:

a.Install the Set-up overlay.

b.Keep accessories’ hose lengths horizontal, either coiled or straight, and no higher than 4 feet of the specified coolant level.

c.Switch on the Power Wave machine.

d.Press the "WATER COOLER ENABLE" button so that the "WATER COOLER ENABLED" light is illu- minated.

e.Press the "PRIME WATER COOLER" button until the "WATER COOLER PRESSURE" light is steadily illuminated.
