Has anyone hooked up an oscilloscope to the AC outlets of an engine
driven welder? How clean is the output? Could you run a computer,
radio, television, or laser printer off it?

We have a house and shop full of stuff that runs off two different
types of inverters and occasionally from two different generators, one
of which is an 8kW Hobart welder/generator. Very few problems. X10
(sensitive) is only happy with the best inverter output, but OK on
both of our generators. Some clocks might not be happy if your
generator isn't well governed, especially if the load fluctuates. No
problem with computers, they're quite happy to run off even cheapy
square-wave inverters by most reports. You might search the archives
of alt.energy.homepower, lots of discussion of the topic.
