ES 275i OUTPUT CONNECTIONS Refer to figure B.1 for the location of the 3-Pin Remote Receptacle and the Output Terminals. OUTPUT CABLES Select the output cable size based on Table A.1. TABLE A.1 Cable Sizes for Combined Length of Electrode and Work Cable ( Copper Cable Rated at 75°C).
ES 275i B-1 OPERA TION B-1 GENERAL DESCRIPTION The ES 275i is a 275 amp arc welding power source that utilizes single or three phase input power, to pro- duce constant current output. The welding response of this Invertec has been optimized for stick (SMAW) and TIG (GTAW).
B-2 OPERA TION B-2 1 . POWER SWITCH - Place the lever in the “ON” position to energize the machine. When the power is on the output will be energized in STICK (SMAW) mode and TIG (GTAW) if the remote is set to local control. At power up the thermal Light and Fan will turn on for approxi- mately 3 seconds.
B-3 OPERA TION B-3 7. OUTPUT TERMINALS - These quick discon- nect terminals are compatible with TWECO®* con- nectors. The terminal provide connection points for the electrode and work cables. Refer to Output Connection in the Installation chapter for proper cable sizes.
B-4 OPERA TION B-4 OVERLOAD PROTECTION The machine is electrically protected from producing high output currents. Should the output current exceed 300A, an electronic protection circuit will reduce the current to less than 200A. The machine will continue to produce this low current until the pro- tection circuit is reset.
D-1 MAINTENANCE D-1 INPUT FIL TER CAP ACITOR DISCHARGE PROCEDURE 1 . Turn off input power or disconnect input power lines. 2. Remove the 5/16" hex head screws from the side and top of the machine and remove wrap-around machine cover.
D-2 MAINTENANCE D-2 ROUTINE MAINTENANCE 1. Perform the following preventive maintenance pro- cedures at least once every six months. It is good practice to keep a preventive maintenance record; a record tag attached to the machine works best.
