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
