Homemade Welding Machine - Simple Cordless Welding Machine 200A 

I made this welding machine so i can use it at the cottage where i have no electricity, i will also add a converter so i can power other things. I definitely should have used a regular gasoline generator but in my country such a generator costs as much as 3 times than the parts for this. This is more like an experiment but I will definitely use it.

Great job at being so negative people. That's exactly what this world needs. This man had an ideal and he got up and acted on it. That's the part of all this with the most importance. You see he could have sit there being negative,had a ideal and never acted but the fact that he acted is what made him successful. Congratulations sir !!! Continue acting on your ideas and you will continue being successful.

I respect all mechanical thinkers and inventors and those who aspire to make or invent something. For that you deserve a thumbs up. However for me If i was in a third world country and needed a welder and would have no chance of getting one but had these parts available, then to me this is the only way that would be a great idea. Being a welder for 40 years...and just speaking for me.... I think it best for me to leave the welding machine design to Miller, Hobart, Lincoln, Esab, HTP etc. Not only for supreme welding function but for welding safety also. You do deserve praise however for your mechanical thinking. I see how you use your ingenuity to make things out of left over parts or pieces that are usually "one off" and your idea, and i like that type of thinking. Thank You!

👍😎✊ 40v being optimal, 36 is better than 24.. use three battery's Also try switching to negative at the rod, and positive to 'ground' clamp on the work.

Pentru voi toti fanii, cu stimă și respect aceste vidio clipurii .!🌹💝💝.👍🍀✌

Love the videos but what I don't understand is why more people with awesome ideas such as yours don't narrate their videos instead of the rank music. I still loved it.

Using an older style general motors alternator with the internal regulator only requires a simple one wire hook up to work. They're also very inexpensive, plentiful, and are available in high amp outputs . Would have been a better option if one was available in his area

For people who like this sort of project, it’s important to note that delicate electronics like a laptop computer need a clean, square sine wave input. This generator will not provide that. It will give dirty power, which can damage many electrical devices. So if you build something like this, you will need to install a sine wave filter. They’re not cheap. If you’re only going to draw DC current, and then run it through a high quality inverter, that’s fine. But really good inverters aren’t cheap either.

you built a gasoline battery charger from what i can see, great stuff now i guess we will build one to.

36 years ago I got my first job as a welder at a fence company. The company had an old commercially made portable welder very similar to this. Forget the brand, but it was simply a Briggs & Stratton engine with the shaft coupled to a GM alternator in a steel cage. No regulator, no battery and no rectifiers in the alternator. Obviously AC output, and I don't remember what it's maximum output was. Probably no more than 80 amps.

This would make a good Inverter/generator with the addition of a 5000 watt inverter. Also, I would use a 140 amp GM Single wire alternator.

All you need is to incorporate an arc stabilizer for a controlled weld. Nice build.

It’s so cool. If you explain how to make it in more detail, it will help a lot to make it. In particular, please explain in detail how to connect the wires of the Converter and Regulator Batterry. Thank you for your education

Can you adjust the welding output at all or does it have 1 setting? That's OK if that setting matches the metal you are working with .

Nice job. I'm planning on making your set up.

First person I know who has e ray vision

It was fun watching you build your own generator. Kudos to You..!!!

Loved this!

Is there a way to regulate the amperage with a setup like this?

Can you charge and weld at the same time? I am going to bet this doesn't have the most stable arc in the world 6013 has a lot of stabilizers in the flux. Probably a good rod selection for a machine of this nature

Many years ago I ran tests on trying to weld with car batteries. Car batteries are chemical power sources and have totally flat DC output. No pulse whatsoever. This makes it hard to arc, in fact it doesn’t arc at all. Test I did in 1980s was I hooked two batteries in series ( like they have here ) to make 24 volt and connected a large 60+ amp battery charger to help give it a little pulse and help it to arc ( a little ) which it did and made it so I could make a couple fairly normal welds with 7014 rod. The next time I attempted this I needed to at least tack a bunch of tubing together , I had two real good batteries but only a little 4 amp charger. It didn’t work as good as before but I did manage to tack my tubing together with small spot welds, kind of ‘ scrubbing ‘ the spots because I had to keep it very short - no arc power. 6011 rods What I would like to see ( and I thought that was what they were going to do ) is for to see what it does with the generator running while welding? It should help it to arc and make it much more usable. Turning it off when welding didn’t make sense, unless striking an arc with the generator running burned up the brushes or something.

Buey bien. ver el vídeo ( las casualidades de la vida ). Y suscribirse y darle al me gusta..Sería todo para la ( Investigación de la Diabetes. Gracias.

some of the first welders where powered by batteries. the amish still weld in this way in my area with large implement batteries. the modified alt. mitigates the power draw and charges the batteries as well. decent packaging for low cost.

Use a smaller welding rod for less amps.

Se le puede poner algun regulador para regular los amperes?

Pra desmontar o alternador? Só pra usar regulador externo?🤷‍♂️

Nice job. But don't you need any regulator and rectifier for the alternator?

You are a master of your craft, I will see you do everything very original

Cool working on the

Kudos! this might justwork for me without wrecking my back up genny! Thanks man great job! And have you tried welding WITH the motor running? think it would give a little more juice!?

Oh,Nice. Some actually still stick welds !!

Just need a welder to make a welder. No problem.

So you are welding w the batteries and the alt keeps up the charge..

So you need a welder to make a welder? Genius!

Salut! What kind of welding rod are you use?

Nice welding set

Nice project. Problem is, 30v welds much better than 24v.

Wonderful welder. But couldn't you self excite the alternator and skip the batteries? I know a lot of guys used the self excited delco 10si and 12 SI to get budget 60-100 Amp welders in the 70's and 80's.

Very good 👍

Dumb question, do the battery's have to be good? Or are they supposed to act as a 24v resister? I got extra bad batteries layn around is why i ask this.

Nice pro👍👍

nice set up where can you get a 24 v alternator also can this idea work for wire welding

Surprised a motorcycle regulator rectifier could handle that much load , since I've never seen one go over 15 amps output...

너무 멋져요 만드는 방법을 좀더 자세히 설명해 주시면 만드는데 많은 도움이 될것 같습니다

The connection of the cable was connect straight to the battery,? The battery is 2x3sm with 12 volts 48Amp hours= 24 volts with 96 Amp hours . How do you calculate 200 amps can you give me idea ? And how's the battery doin ? Is it good for the battery life ? Sorry for the question coz i wanna make one too. I have the same motor,..i wanna hear about your masterpiece... I think much better to use 2x6sm batteries, by the way your video was great. Keep posting interesting video !.

Me gusta esa nueva tennica

What did that engine serpentine pulley come off of? Did you weld it to the centrifugal clutch? They are almost impossible to find for a small engine.

Gosteiii muitoooo bom mesmo🤗

Nice ..thanks

Seem to have trouble maintaining a steady arc?

για να παρετε την ενεργεια που πρεπει να εχετε θα πρεπει να υπολογισετε την ισχυ του volan( M * U *4) γιατι ο παροχος ηλεκτρικης ενεργειας χρεωνει την ισχυ που καταναλωνεται * 4 π.χ ( 20kg *43.96m/sec *4 )

Nice!

Great!

Cuz this is awesome

bro, you only use one phase? WHY NOT ALL OF THEM?

Welding without running the engine?

So you can make it feuless by ejecting that ingine

First, you used a welder to make a welder... and you used a stick welder to make a medeocer stick welder (both can be used to scratch start TIG but you're not using either that way). Second, you don't need the batteries if you wire it correctly, I built a similar alternator TIG powered by a 5hp electric motor and used the alternator field coil to self energize once it was spinning. In my case I just mounted the whole assembly to a 2x8" board and used a headlight dimmer wired to the field coil circuit as an amp output control. Finally, you're not getting nearly 200A out of that. At near 100% efficiency (which this will get nowhere near) you'll stall that 6.5hp motor, and that belt as installed will slip and smoke WELL before that. Forget that fact that I know of very few conventional case alternators that will put out 200A and you're only using 1/3 of the output of that alternator. I'm guessing that you're limited to about 70 or so amps the way you have that setup.

So it welds crappy. You need open circuit voltage of around 80 volts, not 24.

Fantastic idea.

You left out one important part... The part where I hire a brilliant man to build one of these for me.

Mamtap harganya berapa mas

Imagine the apocalypse, and you needed to weld some shit.. this would litterally be able to be fabbed up pretty rough and still work, and it would be better than nothing. Thats cool

Dobra stvar

❤👍

1:32 the batteries will be "serial connected". Is that series, parallel or a combination of both?

Beautiful

Oce banget

Great Sirrr

WHY NOT WELD WILE ENGEN RUNNING .HELP.PLEASE.???

👌👍

Cordless?

Now a days it’s always cheaper 2 buy a 110 welder n avoid all that expense.. that like $700 dlls investment n da 110 welder its only like $160.00 dlls for a good 1 to get da job done rite n better then ur invention.. 😬😬😞😞🤷‍♂️

Try 1/16 " E6013 , that will be the ticket.

Great video and great work , just looks a bit like 50 amp not 200, thanks for the video

Better buy one with all the cost of two batteries

Y si toda mi familia también lo avía dicho att José del MP

That looks very Mcgiver.

Gee I wish there was some narration to this video so we could know what size to make that thing and everything duh 🙄🙄🙄!!!

What's the magic number (200 amps) on current derived from?

Ahhahahaha Comooooooooonnnnnn

losing a ton of power with those solid wires theyre only rated for like 20 or 30 amps

Sure would be nice to know specifically what all went into this and how it works as a welder.

A welder costs less than just the motor.....

So with all that work using a real welder you can make a gas powered batery chargeing spot welder??

Pero no detallas lo que pones despues del alternador

So....all that for a battery charger?

Why are you using car batteries and not deep cycle batteries? Car batteries are for momentary current only and require constant charging when in use. Deep cycle are for sustained current and only require charging when they are low. Don't believe me? Look up the difference in the plate thickness and spacing in the battery types. It also seems like a great way to blow your batteries up and throw sulfuric acid everywhere because you are effectively creating a direct short to weld and have nothing to limit the current. Batteries explode when exposed to direct shorts for too long because, you know, direct shorts create heat...a lot of heat

But its not enough power to sustain arc

But you cannot adjust the Amperage of this machine

Goood mr,,

detail of this welding rod????

Poor comment section is full of "Better ideas" "Why build this?" or "LOL Buy real one" and im betting half the commenters have at least 1 device "jerry rigged" with whatever was around at the time.

Soooo, you used a welder to build another welder

I'd just twist the wires together without those plastic pieces

You st pent more money and time than needs be. You can purchase A 230 amp wire feed welder for 220 dollars. Your engine cost that alone. We are not in the dark ages. This idea has been around for years and years with the off-road community the best thing to do is just leave the alternator on your car and weld from there that's what they do in the off-road.

Welding with bare forearms ? Must like getting burnt!
