Mizu.. thats looks fantastic!..
a question... would a smaller pulley spin faster and give more volts??
tj-7..tellico tested, uwharrie safaried..watch for improvements soon[img]/wwwthreads_images/icons/tongue.gif[/img]..see it at http://www.jeepgod.net
oh yeah, and a 2000 tj, 4.0, dana 44, nv3550
Absolutely incredible write up Mizu!! Outstanding!!
Good presentation, Great web pages, clear, concise, easy to navigate, and straight to the point.
I've not seen a better web article done any better!
A smaller pulley would spin faster but it really isnít necessary.
At 2500 rpm my alternator develops 100 volts. This is great for 1/8" 7018 rod on 3/8Ē steel or higher but maybe a little to hot for thinner metals like ľĒ or less. Thatís the beauty of this thing, if itís burning too hot, just slow the engine down and start welding.
I welded a 3Ē diameter nut to a wellhead today and used 1/8" 7018 rod at 100 volts. I had to decrease the engine rpm initially because it was burning too hot.
I haven't installed an amp meter yet, hence the subject title "99% done".
I am very pleased with how my homemade welder works. I couldnít see paying for a ready-made welder when this home made welder was so easy to make.
The alternator is a bone stock Chrysler 120-amp unit. You are right, no regulator and the alt will make voltage relative to alternator speed.
I am trying to find time to tally all the receipts. I suspect that the final bill we be about 200.00. That might be a little high, but close. The largest expense was for the welding supplies and welding leads.
I wonder if a guy could find a part number on one of these alternators and try to find a rebuilt unit at an auto parts store?
It might be a cheaper way to buy a high output alternator vs. the outrageously priced H/O alternators that are being sold for 300.00 plus.
Just more for the too-do list!
Great Job, very impressive.
I like the idea of not welding from your main engine alternator also. If you carried a spare external voltage regulator and some sort of quick connect you also have a back up alternator on board. Very nice project. Thanks a lot, now I have another item on my never ending "to do list".
If at 1st you dont succeed, your replacement will try and try again
Just one question? I know that you said it was not regulated but arent all chrysler Alts internaly regulated? I could be wrong. Or when you rebuilt it you just got rid of the regulator? Food for thought!
