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). OPERA TIONAL FEA TURES The ES 275i provides continuous total range output cu[...]

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. 2. OUTPUT CONTROL - This controls the o[...]

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. For positive polarity welding connect the electrode cable to the positive term[...]

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. Reset occurs when the outp[...]
