first, the the thread last month with the link to the guy on the mustang board that built his own tig: http://www.jalopyjournal.com/ubbthreads/showflat.php?Cat=&Board=UBB1&Number=222304&Forum=UBB1&Words=welder&Match=Entire%20Phrase&Searchpage=1&Limit=100&Old=6months&Main=221513&Search=true#Post222304 some good stuff in there, too, but if ya wann skip to the actual link http://www.turbomustangs.com/forums/showthread.php?s=&threadid=8872 and then some from my own collection, but it may take me a coupla posts
Damn, the spelling part of my brain already went to bed... some links... Homemade welder links http://www.dansworkshop.com/Homebuilt%20arc%20welder.shtml http://oak.cats.ohiou.edu/~weinfurt/gaswelder.html http://members.home.net/t.molnar/Obwelder1.htm http://www.trailhed.com/welding.html http://www.geocities.com/damonfg/obweld.html http://www.huv.com/jon/jeep/Welder/on-board-welder.html http://www.huv.com/jon/jeep/Welder/portable-welder.html Best: http://4crawler.cruiserpages.com/Welding/alternator.txt
Now, some of you may say screw this, I have a $$$$ machine, I don't needa look at this crap... good for you, shut up! Its for entainment and education value then... It'd be good to note, that these last two diagrams show no current control on that field winding... thats where the guy who made the tig putthe headlight dimmer... any "J Lo assed" rheostat/ potentiometer will do here. Also, if you like silence, you could get one of those "compressor grade" electric motors from harbor freight, that'd run the alt too. I'm gonna try the lawnmower approach someday: (sorry, J LO ass-sized jpeg.) fukkit, lets try that agian... -J
[ QUOTE ] How many rpm does the alternator need ? [/ QUOTE ] That depends on how much output current you want! Figure your alt on your car probably starts getting to work at about 800-1000 rpm... ENGINE rpm, remember, alt rpm is higher because the crank pully is much bigger than the alt pulley, keep that in mind. And, the alt can be driven at crank speeds up to 5, 6000 rpm! Figure due to the inefficiencies of its design, and basic laws of physics, you're gonna have to put a lot in to get a lot out... don't know much for certain as I haven't built one of these contraptions yet, but I gotta pair of 140 amp caddy alts waiting for the day... -J
