RECONNECT PROCEDURE
When received directly from the factory, the machines
are internally connected for 230 VAC. Reconnection
will be necessary if a higher input voltage is used. To
reconnect the Pro-Cut to 460 VAC or to connect back
to 230 VAC, follow the directions as outlined below.
Follow this procedure ONLY while the Pro-Cut is dis-
connected from the input power.
Failure to follow these instructions can cause immedi-
ate failure of components in the welder.
1. Open the access door on the back of the machine.
Connection instructions are also included on the
inside of the door.
2. For 230: Position the large switch to 200-230. See
Figure A.2.
For 460: Position the large switch to 380-460. See
Figure A-2.
