RECONNECT PROCEDURE
Multiple input voltage welders are shipped connected for the highest voltage listed on the machine’s rating plate. Before installing the welder, be sure the recon- nect panel is connected for the proper voltage.
CAUTION
Failure to follow these instructions can cause immedi- ate failure of components in the welder.
To reconnect a multiple voltage machine to a different voltage, remove input power. Follow the input con- nection diagram, located on the inside access panel cover, appropriate for your machine’s input voltage. These same connection diagrams are shown below.
For 208, 208/230 & 230/460 volts AC - see Figure A.4.
For 230/460/575 volts AC - see Figure A.5.
