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).
OPERATIONAL FEATuRES
The ES 275i provides continuous total range output current adjustment, selectable welding modes and local or remote output control. Welding characteristics can be controlled via an arc force control. Additionally, starting characteristics can be adjusted via a “hot start” control.
WELDING CAPAbILITY
The ES 275i is rated at 275 amps, 35% duty cycle (based on a 10 minute cycle). It is also rated at 200 amps, 100% duty cycle, and 250 amps, 60% duty cycle.
LIMITATIONS
The ES 275i is not recommended for pipe thawing.
