@JohnDeere30201 I would think that if you use an engine that has a charging stator that generates 12 volts then you could wire a switch to turn on alternator/welder..
You need to change your ground cable and your welding cable because your undercutting your welds instead of depositing welding material into the weld not trying to criticize or anything just trying to give you a better weld that's all but I like this setup.
@junkman6261 I should say that the cables need to be switched one for the other not replaced which will give you welds that are better looking and stronger welds.
I've been holding on to an old 17hp briggs just for this but I'm also gonna use it as a generator, I have an idea of installing a regulator for 12VDC to run a inverter to give me AC power also, thanks for the links in the description...
@njmvermont The voltage regulator has been removed so it now produces up to around 120 volts, depending on the engine speed. The faster you spin the alternator, the more voltage. It does of course have it's limits on voltage but I don't know how high it is because I have never checked it.
Voltage has nothing to do with it. The alternator charges the battery (and even with the regulator out of it, you won't get much more than 18 volts) and when you're welding, you're actually shorting the battery on purpose ..... if your battery's a 550 CCA (Cold Cranking Amps) that's how much you have when you strike the arc and then it goes down as you drain the battery.
@FreakyGearHead You may be right but don't get confused here. You are not welding with the battery, The welding leads are connected to the alternator only. The battery only serves to start the engine and energize the alternator to make it generate electricity. I will do a voltage check to see what I am welding with but I have a few things I want to do like put a car battery and another alternator in so I can also use a power inverter. Thanks for your input though.

Those that knock this idea are simple, the best welding is done with direct DC! This is the same as a larger portable welder, just smaller in scale. The first portable welders were built the exact same way as this, these units weld awesome!
@junkman6261 My cousin built one back in the 50's with a ww2 airplane 200amp 24volt generator, I will be restoring it and using a newer engine to power it, the old Wisconsin v4 is seized from sitting
I would have thought that one could have welded straight off the battery, and used the generator for a fast recharge... to keep it topped up so to speak.
Ey man, nice job, is the battery just for starting the engine, or is it hooked up to the alternator in some way, Do i need a battery if i have a pull start engine?
How come the engine doesn't alternate in speed?? Any mobile welder I ever used the engine dies a little when welding ;-) Nice job tho, if it is the real deal :-)
Junkman, that is one of the BEST pieces of backyard fabrication I have seen in a long time. EXCELLENT piece of work sir! This outstanding vid is going in my favorites. Nice job, I would like to have info on building a similar one. Thanks
Nice job. I got to use a high power version of this and it really welded nice due to high frequency full wave rectification out of the alternator (internal 3 phase then rectified by the diode stack). A welder like this is perfect for home use and you don't even need a power cord. Put it in the back of your truck and go anywhere. The one I used was a 120amp unit still in the truck but had the welder jacks right by the alternator. Was used for welding broke frames in off road racing.
@Mikdeelo Well for a homemade welder that i havent perfected that is the best I can do. Sorry :( I'd love to be able to weld better. Thanks for commenting though.
This is cool, I'm working on a similar project but instead of a welder its going to be a generator to charge my car battery that feeds into my inverter and gives me 120 ac to run lights around my shop
Hey Daniel... I've seen those sites before,as a matter of fact the welder built by Greg Weinfurtner at that second site is the one that got me interested in building one...Your's seems like a much simpler approach though..
I've been researching this type of unit for a while online and still don't know how to build the dang thing..LOL.
I've got some pretty good links for info if you're interested.
The alternator is no longer regulated with a regulator. It uses engine speed to regulate welding current which I believe I need to change my drive pulley to a larger one. The battery only supplies current to the alternator to get it to generate current so I believe you would say it is in parallel. I'm not sure of the welding voltage so maybe I will crank it up and get a reading for you. I believe it will be around 115 Volts though. Thanks for your interest and Happy New Year!!!
@junkman6261 I already posted a video if you click on my name there it will show up, its the only video i have uploaded. It is the exact same thing you built just with a variable feild. works awsome used a 160 amp semitruck alt.12.5 hp briggs single v belt. I will post a video of the build up. It was all salvage junk from work or free parts I got over the years total cost was about 150 bucks after guage, paint, fasteners, wire and clamps.
Wow great project! I want to do something like this. I plan to use an old s10 alternator,old lawnmower engine and old car battery. Anything I should know or forgot to add?
I believe the faster you spin the alternator the more current it will put out. I don't believe mine is welding at full potential and it barely puts any kind of load on the engine. I need to get a larger pulley for the engine. If you build one, please let me know how it turns out for you. Post a video of it also.
Thanks for the info. I have decided to make the microwave welder. With that I may decide to make one of these. Either way I'll be posting a video if a succeed.
is there anyway you can go over the wiring of the HOLE WIRING system diagram so we beginners can write down the wiring plans I CAN"T find a schematics of the wiring any where I have found a lot of pictures and directions but that don't help to much THANK YOU
Man you just gave me my winter projects. Your links helped alot and i am also going to try to make the generator off the links keep up the work junkman
Thats alright! Props to you for thinking out of the box and making something that is unique and functional. Oh, what rod number were you using, that bead was pretty shiny?
same kind of regulator that came off an older 10 hp kohler horrizontal shaft from John Deere 210. I saw one one ebay. In the future I may add a second alternator and just use it. Thanks for the compliment.
Thanks for the compliment. Yes a 9hp honda should have no problem, the only issue would be your battery draining. On mine to solve that I use the stator from the engine to charge the battery. I don't know if your honda has one. Might have to run two alternators.
ahh, yah I believe it does. I also have an old sears mower w/a 13.5hp briggs I could use. I think I'd just mount the alternator where the deck would be, and there's plenty of places to mount switches, and you could drive it to where you need to weld....
man, I gotta get to bed or there's no telling what I'll get myself into.
Awesome! I love these re-purposing jobs. Old lawnmower and an alternator lying around? NO PROBLEM! I'LL MAKE A WELDER! ;D
Sadly the idiots of these days don't get it. They're more than happy to waste their money buying things off the shelf. And they'll never understand how it works, or how to fix it if it breaks.
Keep up the great work, looking forward to your next video!
How many Amp is the Alternator ? Did you remove the Capacitor , the Exciter Diode , and gound the regulator out to the frame of the alternator ?? What size rod have you tryed welding with ? I just converted a older GM 61 Amp alternator to do the same thing but yet have hooked up my engine and welding cables yet , I got my info from Google under the search of ** Weldernator ** I`m hoping I can weld at least some 3/16th or 1/4" steel plate with it , only thing I would change on yours isbatteryspot
Yes I removed all those parts. So far I have only used the small rods you can buy at Wal-mart and have no problems. I have welded on 1/4" steel plate. I believe mine would weld better if I had a bigger pulley on my engine. I'm going to buld another welder and try different things and keep every one updated.
@hool10 actually yea that is a hemi a hemi is a kind of a combustion chamber where the spark plug enters directly in the top of the head so no the pos dodge isnt the only one with a hemi hell my pos honda civic has a hemi so does all the other four bangers v6 and v8 that have the spark plug eneter through the top of the head my yz 250 has a hemi my honda has a hemi my briggs and stratton has a hemi wow how ironic is that most of everything today that runs worth a shit has a hemi
@jfkyz125 not to be the yotube know it all but not everything is a hemi. hemi stands for hemispherical head, in other words it means the head is in a concave shape or inverted circle( id ont know exactly how you word it lol) with the spark plug in the exact center. either way a hemi is the most efficent way of ignition and combustion thats why chrysler tradmarked it or copy righted it when the knew what they were doing lol. also im sure your yz has a hemi type head (2 stroke) hope this helps
