Is there any practically smallish implementation of these welders that could pinch hit in a backup generator role, or are they just stupidly large and expensive beyond all sense for a hobbbyist/hacker type application?
It would save me the price of the extra outlet on my dryer circuit.
Check out Miller Bobcat series. 10kw single phase or 11kw 3 phase generator plus onboard stick welder. Accessories add mig and tig capabilities. Around $3500 new for base unit. A "big" unit like what you're imagining can easily run $15-20k.
