can you demonstrate more?

Battery details (size,watt) bro

Just a question, would the joint have the same strength as to that of regular machines? This looks fabulous for tinkering with.

@@PC-tz6rw I am a welder by trade and I know that this is not a good weld. Why because it requires something to shielding gas.

Could you explain shielding gas? Do you think this would seal a small crack in a catylitic converter or do I need like a filler metal?

@@spycat917 shielding gas displaces the atmosphere in and around the area being welded. Even if you are fixing a tiny crack. The other method is to use a welding flux. In the process of producing a metal Argon or some other method is used to prevent oxygen from entering the molten pool.

Yep, yep, yep. Your comment was earlier than mine. Don't do that unless you want to get rid of your battery pretty soon otherwise your battery will degrade and die even if it's new.

Yes, that's right

can I use an adapter with output of 12V 0.2A 2.4VA? or it is better to use 9V 850MA? or none of it will work?

@@senpaiseiichi3645 No! The electrode requires quite a high current to heat up. Instead you can use a 12V/5A (60W or ~72VA) transformer as the source. The higher the current rating the better. Regards, BTG TIGER 1997.

@@btg5975 To be clear, a 120 or 220 Ac to 12V/5A DC transformer?

Exactly right the same thing happens when I short things out with my extension cord. That's not welding. The very definition is joining two metals as if they were never separated. Spot welding works because no air is between the two weldments.

@@donaldcampbell7894 I guess in a rare case were you need to spot weld a battery temporally in an emergency in the middle of nowhere then it mite be a good idea.

You should look up explosive welding. It's pretty crazy shit

SalemikTUBE I up-voted you, but: Actually, upon consideration, there might be some CO2 shielding present due to the hot carbon rod absorbing the free oxygen in the vicinity, albeit the oxygen has to already be there to be absorbed. I might have to give him that... Also, the carbon rod might cause some surface hardening and brittleness. All in all I agree it is not a very good method.

U dont need sheilding gas or flux to weld thares sodering spot welding and plastic welding that dosent use shielding gas but you are right that its not going to be a good weld or a tack and would break easy

lol

The process should hav also been explained by narration

@@dilipsengupta2995 could have at least typed something out for us

That's funny as H---!

The guy shares a great idea, then an imbecile comes to talk shit. Congratulations on creating colleague.

But of course. Only, it has to be powerful - able to deliver constant high current (30 - 50A or more - the more, the better) without a drop of voltage during a long intervals. Practically, it would need to be a stabilized PSU of at least 500 Watt (say, 12 VDC/40 ADC). That being said, traditional PSU would require a transformer with a soft iron core as powerful as 1000VA, massive "graetz" (bridge rectifier) and a lot of "filtration" (capacitors with huge capacity). The more current and more voltage in a battery (or PSU), the tool would be able to weld thicker pieces of metal in less time...

Those carbon rods do not come in AA batteries but two of them do come in 6 volt batteries the big Square batteries for flashlights the big Lantern flashlights

It's 12volts, probably not gonna kill you. Disfiguring at the worst 😂

12 volts won't kill you but you'll get a nice burn if you touch the electrode for sure.

@@user-bt2lx4gy7h its won't kill us with 12v. But u will get pretty good wound burn if the battery blow close up to you

I don't think he's referring to the 12V probably more towards the chance of exploding batteries and flying shrapnel. "Just a thought"

Carbon electrode like arc lamps used in early projectors also can emit carbon monoxide,toxic gas.exhaust must

Aluminum is VERY difficult material to be welded. This tool works good mostly with copper and iron/steel.

Amperage

What do amperage mean

No allowed to be use adoptor for like this project it needs of high amper required ,but if you whish to to do like, transformer with high amperage and ractifier diodes are required to be perform well,

Prison inmate comment

-yes, but the question is, is there CO2 present from the rod, or no shielding; how do we classify this? I can't find this in my welding manual, LOL

Until it last !!!

😅😅😅

Could be used as a tack welder for like batteries, but not a traditional welder by any means.

soldering ;!

Soldering iron handle

No. And risks are huge with the hight voltage. Don't try ! ☠☠☠

What if ur not at home. Ur broke down on road side?

It will not weld anything. This is not a welder. It is only heating the metal with the carbon arc. Ignore everything in this video. It has been put together by a fool with almost no knowledge of what he is foung.

no

Even though its only 12 volts, it uses very high current. I believe these wall warts have their current too limited to do this.

Kindly use old battery which is nearing replacement.

if you have enough money to buy any amount of gold just get a real welding machine, the welds will be a lot cleaner

The answer is yes but for those things just use an arc furnace. Where you can literally melt the metal to caat

The amounts used by the normal same welder.

No!

No.currrent must hight to produce hight temperature

I don't think so, amperage difference.

He was using 12v. Battery 🔋 just not a standard car battery. When off road for emergency repair, Use jumper cables and welding rods temp fix to get you home. Proffered use EXTRA BATTERY NOT UR MAIN BATTERY. That way your guaranteed to make it home and not damage your vehicles electrical system

I think you can't because when you use adapter it will defuse it...

I think no because adaptor have a current limit. And it will damage if you doing that, because it need a lot current almost same like short circuit.

लडललग

Both

yes, because touching of positive terminal of 12 v battery through AA battery carbon to negative terminal of the 12 v battery, is nothing but shorting battery terminals, which may not only weaken battery also some times battery exploding also may take place.... An electronist

Lel

HAHAHAHA true

try adding a ac capacitor first lol

why?

Please explain what you mean. I am very interested in what you commented but don't quite understand the concept. Thanks

@@andyfleege8504Electric arc furnace.

Can you tell me what that is that you used to make the electrode holder from

not quite...an electrode melts metals in part A and part B and deposits metal from electrode to blend with melted metals in both parts and creates slag to shield the weld from the air...the carbon rod just creates heat to melt metal in both parts that stick together without blending
