This unit is equipped with Auto-Line. Auto-Line is an internal inverter power source circuit that automatically links the power source to
any primary input voltage from 190 to 625 volts, single-or-three-phase, 50 or 60 hertz. It also adjusts for voltage spikes within the entire
range.

Welding range for Stick process
is 5–750 amperes. For TIG, the
amperage range is tungsten di-
ameter dependent. See Section
