GENERAL DESCRIPTION

The Invertec V250-S is a 250 amp arc welding power source that utilizes single or three phase input power, to produce constant current output. The welding response of this Invertec has been optimized for stick (SMAW) and TIG (GTAW).

OPERATIONAL FEATURES

The Invertec V250-S provides continuous total range output current adjustment, selectable welding modes and local or remote output control. Welding character- istics can be controlled via an arc force control. Additionally, starting characteristics can be adjusted via a “hot start” control.

WELDING CAPABILITY

The Invertec V250-S is rated at 250 amps, 35% duty cycle (based on a 10 minute cycle). It is also rated at 165 amps, 100% duty cycle, and 200 amps, 60% duty cycle.

LIMITATIONS

The V250-S is not recommended for pipe thawing.

The V250-S should not be powered from the auxiliary power supply of an engine welder. Special protection circuits may operate causing loss of output.
