how to make a onboard welder for about $100

I just got done putting a welder on my Jeep for about $100. here is the price list (rounded to the nearest dollar)
Alternator-$45
2 wheel pulley-$9
belt-$8
jumper cables-$33
alternator bracket from junkyard-$5
I got a spare alternator for my jeep (if mine dies I can rewire the welder back to a alternator)
and took out the capacitor, exciter diode, and insulation screw from the brush, you have to do this because a alternator can produce plenty of power but these parts prevent it from producing to much for your vehicle but this is gonna be to weld not to run your jeep. then I put it back together and mounted a second alternator bracket on my wheelwell and put the "weldinator" in that bracket. I put a 2 wheel pulley on the alternator to run a belt to the weldinator. I then took some 4 gauge jumper cables and cut the clamps off one side and put on eyelet connectors to put on the positive and negative on the back of the weldinator. Also there are 2 prongs on the back of the weldinator, if looking at it from the back the one on the left needs a 12v power source you can wire it to the ACC box with a inline fuse (you need power to make power). I was told its about the same as a 200 amp welder but Im not sure, I know today I was able to cut a 1/16 plate in half with a 6013 rod. If yall want to look into this more I used these 2 webpages for most of my information. Also I know the video is not for a jeep but it shows how to wire everything up.

Would it be possible to set it up like an AC compressor using an electric clutch to power it up ? Just thinking out loud.

Cool. Got a few questions. What is the Alt bracket from? Also how do you remove the jumper cables when they are not be used for the welder. Last I noticed that your alternator is not hooked up. Is that just do to you not finishing or does it need to be unplugged during welder use.

As I remember, Jeephammer had a post about onboard welders a while back. A quick search didn't help find it. If I remember correctly, he mounted the alt( a ford one) to the steel front fender with a fabed bracket and a turnbuckel to tighten the belt when welding is needed. I think the belt is just left off when not in use as a welder. Mabye someone can find the orignal post. Im probley not typing the correct words. I have glass front fenders, but, if a piece of square tube were welded to the frame in the correct position, that could be a starting point for a bracket.

I got the alt bracket from a postal jeep with a inline 6 I found in a junkyard, Its identical to the one holding on my alternator but instead of putting it on the engine I just put it on a metal plate and shaped the plate to fit the wheelwell. I remove the jumper cables when not in use, I wanted to do this as cheap as possible but eventually I will run leads from the welder to a box with connectors for real welding leads to connect to so all I will have to do is pop the hood, plug in the leads and flip the switch. You dont have to unplug the alternator you need the jeep to be running for this to work so your gonna need your alternator working, Also you control the power with the RPMs. Tommorrow I will take off the welder and take some pics of the bracket and TRY to clean up some wires so its a bit easier to look at and figure out.
