I don't know about that but I read a story, with pictures and every thing
:), about a guy who used a lawn mower motor and alternator to make a small
DC welding rig. Might do a google search for something like that

They're very cool, but a welder is needed to build it. Catch 22! :-)

Mother Earth some years back.....Think they were welding up a tower for
Jacobs at the time.

Howdy Bob,
I have used home made, battery powered, arc welders for a fair few years.
On Yahoo, I have set up a site called:
http://groups.yahoo.com/group/Amptramp/
There, you'll find a good deal of info on my 3 battery welder.
You'll see how I moved from this, to the 'Amptramp', a 1 tonne, diesel
powered
arc welding system.
This project was built, using my battery powered system.
I hope this will be of assistance.
Best wishes, and showers of sparks too :) .
Steve.
