OPERATION

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).

OPERATIONALFEATURES

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.
Read and understand this entire section before
operating your machine.
