OUTPUT CONNECTIONS

The output (welding) cables are connected to the output terminals marked “+” and “-”. See Table A.1 for recom- mended cable sizes for the combined lengths of elec- trode and work cables. They are located at the lower right and lower left corners of the front panel. Strain

relief for the cables is provided by routing them through the rectangular holes in the base before connecting them to the output terminals. Lift the output terminal cover to access the output terminals. Lower the cover after making the connections. See Figure A.6.
