To reconnect your machine for the proper input volt- age, see the reconnect instructions on your input access door and:
1.Move the large input voltage switch to the proper position according to your input volt- age, and the labels near the switch.
2.Move the auxiliary “A” lead to the appropriate terminal, according to your input voltage and the labels near the terminals.
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
WIRE FEEDER CONNECTIONS
Refer to the Accessories section for Wire Feeder Con- nections.
Refer to Setup overlay in Operation section for Wire Feeder Configuration.
