Hobart N-400 Can this unit work as an AC power supply

I was looking into this unit that is driven by a 25 Hp electric motor. Thinking of putting a small diesel on it instead. Owner says it's
nothing to set the unit up so that it can be used as a backup power supply (220volt) but I don't trust him. Anybody had any experience with these?
