I was thinking 3300 Watts would carry 30 Amps at 110V AC
http://www.the12volt.com/ohm/page2.asp allowing me to use my mini-mig, or a
sawzall too. I figure on the Jeepster i can easily put an air tank under
the floorboards in front of the rear axle, and put the compressor under the
hood.

Problem is, 30 amps on the 110 volt side would be 275 amps on the 12 volt
side (assuming 100% efficient). You could run small tools though, I don't
know about a welder. Best bet would be to mount the inverter very close to
dual batteries using large gauge, short lengths of cable.

Use a separate alternator and make an arc welder:

You folks have me totally confused here....

I have it figured that a 350 watt or so continuous draw unit will turn a
tool that is 3 amp, and maybe a 3.5 amp, but it could smoke out if used
long.

Basically a 100 watt unit for every 1 amp draw.

They do sell bigger ones, but they start getting expensive fast.

My 350 continuous has two 115V outlets each separately fused with heavy
wires and alligator clamps for hookup direct to the battery.
