Miller does make a unit named PIPE PRO 304 CC/CV W/DUAL POWER
which lists for around $13K. It will run off 230VAC single-phase
power.
By comparison, if grid power is not a requirement, the
TRAILBLAZER 301 G(KOHLER)CC/CV AC/DC 10,000W lists for around $4200
and is an excellent machine. A diesel version is available as well.
This unit is rated for AC TIG. Just cannot run it off the grid.
I have used a Bobcat for some time for portable power and
stick welding. There is usually some cost in wiring up a receptacle
for any non-engine drive, which I avoided by getting the Bobcat.
There ARE limits to emergency generator use - about 10KW and
about 8-10 hours for gasoline-fueled, depending on load.
These units will run 3600 rpm if there is even a small load attached.

I'm currently thinking of buying a welder that I can use in the
field and also use as an emergency generator. Do any of these welders
have provisions for using the welder off of grid power ( 230VAC, 1 PH,
in my case) or would I be better off buying a stand alone welder +
generator? I'm thinking basic stick welding, but I'm not ruling out
TIG, depending on the price tag.

Recommendations on brands / models would be welcome.

Thanks.
