To operate at 208-230 VAC:

1.Open the reconnect/input access door.

2.Move the input voltage switch to voltage = 208- 230V position.

3.Move “A” lead to the 208-230V terminal.

To operate at 440-460 VAC: No setup required. The machine is factory-connected to operate at 440 volts. To verify, do the following:

1.Open the reconnect/input access door.

2.Check that the input voltage switch is set to Voltage = 440-460V position.

3.Check that the “A” lead is at the 440-460V.

OUTPUT CONNECTIONS

See Figure A.3 for the location of the work terminal, electrode terminal, remote control amphenol recepta- cle, water cooler fittings and wire feeder connections.

WORK AND ELECTRODE CABLE CONNECTIONS

Size

Use the largest welding (electrode and ground) cables possible — at least 70mm2 (#2/0) copper wire — even if the output current does not require it. When pulsing, the pulse current often exceeds 650 amps with the Power Wave 450. Voltage drops can become exces- sive if undersized welding cables are used.

Routing

To avoid interference problems with other equipment and to achieve the best possible operation, route all cables directly. Avoid excessive lengths, bundle the electrode and ground cables together where practical, and do not coil excess cable.

WATER COOLER CONNECTIONS

The water cooler fittings are a quick-connect type. Refer to the Accessories section of this manual for water cooler operation and antifreeze mixtures.

WIRE FEEDER CONNECTIONS

Refer to the Accessories section for Wire Feeder Con- nections.

Refer to Setup overlay in Operation section for Wire Feeder Configuration.
