Photonicinduction playing with dangerous electricity right above a carpet... and no one sayes anything. Me playing with 9 volt battery above a metal plate.. Mom: "STOP, you are going to burn down everything."
I used one years ago repairing plant machinery, used to be mainly 3.2 and 4mm rods, there a great welder, they weld great all day, the morning after the machine was still warm.
Awesome ! Those inverter welders make welding a lot easier , especially on awkward steel. The old transformer welder looks brilliant and well made English quality. especially the tapping switch.
What’s your bet for his first words “I ain’t avin it”, “where’s my fucking hammer?”, “I popped it”, “I wanna blow it up” or “silly fucking lightbulbs”.
Its been a year, but ill try answer it: First off, you may want to not touch things far before it kills you. You did provide a neat line in the sand though, but its still not cut and dry who dies and who doesnt. So: 1) Generally, most damage is done to tissue by heat. Except for the criterium you put up; death. That one is most common from AC, that pulses the heart out of rythm, rendering it non functional and possible unable to reboot after the outside electric force is removed. Same applies to nerves/brain, up to an extent. So apart from those, it is heat, resulting from a current running through us, with a minor resistance. And that will eventually, depending on how much it is and where it is, burn our cells = celldeath. And on top of celldeath, we get all sorts of systemic reactions which may also kill you. 2) In order for a current to run through us, the Voltage needs to high enough to overcome the blocking resistance we have. If resistance is too high, there will be no current = no heat = no burning. If the resistance is 0 (theoretically), a huge current may run through, but it will not create heat = no burning. Thats also why you can see him melt spanners, steel rods, etc, that are thicker than the copper cables connecting to it. So why doesnt the copper melt? Its melting point is lower than that of steel. Its because copper is a better conductor (has a lower resistance), than steel. So provided a voltage is connected to us that overcomes our resistance, a current will flow and the region the current flows through us, will heat up. 3) But we are not consistent in composition. Even though people are anatomically 'equal', our body chemistry may differ quite some. And it will also vary in a person depending on conditions over time. So the current may run through muscle, or through vains, or along nerves, etc, depending on their conductivity at that time. And if we apply the electrodes to our skin, a huge differnece there already is if we are wet or not, or even better; sweating. Sweat contains a lot of salts, in a water solution. And that is a great conductor, while the skin itself (~dry) is more of an isolator. So when your skin is very dry, a current may not run at all, while when you are sweaty, it may run easily. Suppose we overcome both by a high enough current: In a sweaty person, the current will run over the skin; through the sweat. That will heat up and may steam off even. That initial heat will burn from the outside in. A person with a dry skin; the current will run under the skin somewhere. The heat will originate there and burn you there. From the inside out. 4) Generally; voltages up to ~40 V will not allow much current to flow, if at all. (depending on how dry/wet/sweaty your skin is. Anything above that will penetrate through the skin and a current will flow. But it may not cause any harm at all, because it also depends on how much current is allowed to flow. After all; P=U*I (Power = voltage * current). So you may grab 10 KV, but if the current allowed to flow is limited to 0,1mA, it is not going to burn you anywhere in the near future. It will heat up so little, out body is able to get rid of the generated heat easily. 5) Another thing to keep in mind is that you may touch an open mains wire and nothing will happen. After all, no current will flow if there is no closed circuit. You may be wearing rubber soled shoes. Standing on a rubber matt, or anything such, which prevents a current to flow. It is how birds can sit on high voltage wires and nothing happens. Well, as long as they dont touch the other wire that closes the circuit through them, no current can flow. If they do, it tastes just like fried chicken i guess. 6) Examples: A young guy is laying opposite my mom at the graveyard. He was biking with his GF here, 28 years ago, over a dike and lightning struck. He died instantly. Other people were struck and they had no damage at all. Others had skinburns. (it all depends how much, where, wet/dry, etc) You may hold batteries with no problem. Ever put a 9v on your tongue? Try it. Tongue is wet and saliva full of salts and sugars and so; conducting very well. There is a reason welding devices are limited at ~40 to 50 V. After that the voltage would become dangerous for welders to work with. So it is not so easy to answer what is dangerous and what is not. It depends on a number of factors, which i tried to explain. I hope it clears it up a bit. Seeing what our dude here does in his videos, it seems to me he knows very well what he is doing. But i understand to a lot of people it must seem like magic. (also because of the many comments on how the grid would suffer from what he does, when in fact, a lot of the things he does are not that high in power consumption. It just seems so, bc he shows things you often dont see in electrics and look impressive. He is also limited to what the cables that run into his house can carry. And the main fuse box. Ofc he circumvents it somewhat, with HUGE capacitors, which store an amount of energy, similar to batteries, but able to release that all in a millisecond. Those are charged from the mains. You cant just take 100 amps @ 240V from the mains. But you can load capacitors and then use that for a short time)
I love those oxford welders they are a joy to weld with!! sad to see them repurposed as they kick ass, in saying that at least they will be used and not scrapped
I have an old arch welder that my grandfather made. It would weigh at least 50Kg (110lb), it's really really old in a wooden box with material insulated wiring. It would be a fair bit more than 200amps I would assume, it has no trouble blowing holes in 10mm thick plate. I have to run it on 15amp mains @ 240v, it blows a 10amp fuse real easy.
Even tho inverter welders have more complicated stuff inside, I still find the transformer based ones more interesting, it's much easier to customize a transformer than a switchmode supply.
hi there you need to be very careful my friend doing this !!! I have seen those copper coils unwind and cut through the metal casing of the machine ! The copper goes hard in places usually back from the soldered joints on the choke and where the clips bolt on to the paxoline selector arc and flash across so check the tightness as well as the copper braided connection stay safe and make more vids mate
That is why the copper can handle UHV+ (Ultra-High Voltage and up), or 57,009,864 Volts. My friend, these copper wires should be used to replace HV (High Voltage) wires for transmission, even in short-circuit, or sudden voltage overloading, conditions. People who select the proper line material should know that and select it.
Hi ... Did you have this plugged straight into three-pin wall socket (240 volts (13amps)) ... !? I see you have run your ''input'' electrics through a couple of things. Does one of these oil cooled welders pull more and more from the input electrics, or can you just run them up, and they will create whatever they need on the out put side! I have one; but not sure if I can run it from the house electrics ... !? Thankyou. Interesting vid. Best ... William (Hampshire UK)
Can still see the dots on the camera from his playing with the lasers. You won't find anything like that around here for such a low price, they'd be scrapped for the metal before that happened.
Hello Mr Photon, So I've been wanting to build a big Tesla coil but no power supplies (microwave oven transformers) ever lasts long, This is the answer, and I can even use my Variac. Awesome video. Thanks for all your hard work making great video's. Don't worry, I wont burn the carpet.
A bit late to the table but I just got a "new" arc welder (read better than my cheapo) and was considering doing something with its guts. Anyone used something like this for hardening or annealing etc??? Any pointers or links?
You're crazy mate, but you already know that, don't you :D On the other hand how disappointing that the propane canister didn't blow up in a spectacular way. I guess they rely on explosives in movies more heavily than I thought :P Oh and the tip on the oil welder is a VERY nice one indeed! Thanks for that!
Being that you have outdone most of the things you have come across ..... Is there a way to "boost" or upgrade those little electronic inverter arc welders???? Your resulting output would be greatly appreciated (even if it takes sending it to,you to mod it!) the size of them little buggers is awesome, but their performance is lacking quite a bit (7-17mm effectively) Looking forward to your response
hi its just to see what size roughly cable size and fuse ?? ,used these about 30+ years ago at welding school and forgot all about them till i seen the vid and thought can have a bit of fun with one and also a half decent welder as well ,any time ive had a sh^% day put one of your vid on and it doesn't seem so bad after all ..so keep it up
"induction heaters" no need to complicate things with all the electronics or transformer heavy cores . but efficiency is low when turning heat into electricity at power plant. so in large scale factory settings they just use coal straight .
hdyudu HDYUDU how the fuck are you gona use a fucking element which is resistive and soft and get it hot enough to melt fucking steel before the element itself melts and drops ???
forthereg Don't worry we all ready got something similar that can heat steel more controlled in a instant but more safer it called an induction forge using both electricity and radio waves to do the job sort of like a microwave oven but can heat product to much higher temperatures
***** if you have a stick/ arc welder just stick the clamps to each end, turn the amps up till hot. it took 500 amps to heat up a 6'x8' plate of 1/2" steel to 100f at school. the a rosebud on a oxy/fuel torch to get it to 250ish. so you will need a beefy welder to do it.
does it look like the one in my videos if yours is similar to mine i wold love to know the brand name i have no idea what company made it cause when i gut it it was so rusted and covered in 3 coats of paint i couldn't find a name or model number
The hottest point is at the arc. The metal closest to that arc will melt. Eventually you use up the whole rod and snap in another.. If you were to just short circuit the welding rod at a sufficient amperage without producing an arc and just held it there, the entire rod would eventually heat up enough to become molten.
Did this welder contain PCB or just standard mineral oil? Also hope that you took proper safety precautions. And what would you do with the oil after that? Can you just that it down to you local recycle facility and the are just going to take it and not asking anything about how you got gallons of PCB?
Photonic, i got a real nerdy technical question for you. Regarding AC wire heat vs DC wire heat. Why is the ratio 0.707:1 if both use equal amps and equal volts? My classmates and i have been racking our fucking brains to figure this correlation out for a project. (We're in aviation maintenance school)
Dude, I love your videos but I have questions - in lay-men's terms, what's the difference between lots of amps at no volts and lots of volts with no amps? What are examples of real-world uses for each? Thanks for sharing your knowledge with all of us!
2 years later, I will offer a reply... First the answer to your question. The ultimate answer is nothing, because both are zero. However, that's also not the ful answer because Volts and Amps are two different things. They only become useful when both are used together. If one is zero, then the other is useless. Only when both Volts and Amps have a non-zero value, then Watts (power) can exist. . Voltage is the difference between 2 points, where potentially some electricity could/might flow. Current (Amps) is the *amount* of any electricity that is actually flowing (due to voltage). . Often an analogy of water is used... this is not a perfect model, but let's consider a huge lake, with a dam blocking it from flowing into a river below.... . 1. The *height* of the Dam is the potential difference (Voltage) between the dam and the river. 2. The dam itself is the Resistance (Ohms) to that water being able to flow from dam to river. 3. The *amount* of water that is flowing to the river is like the Amps. . If the water is completely blocked by the dam (infinite resistance) then no water will get into the river. It doesn't matter how low or high the lake is, the water cannot flow. - This is like having a High Voltage against a high (total) resistance that stops it, so the Current will be zero. . If the lake and the river are the same height, there is no potential for water to flow. It won't flow down into the river because there is nothing to push it. - So this is like having Zero Voltage, because there is no potential difference. No current (Amps) will flow, and the resistance of any dam doesn't matter. . If there is a height difference and then dam is suddenly removed, all the water will flow between the lake and river until they are the same height. While that water is flowing, it's a current. - So if there is a Voltage and if Resistance is low, the electricity with flow at a "rate of" Amps until all the Voltage is gone. . OK, now let's make a hole at the bottom of the dam, allowing some water to come out. We have will a flow that depends on two things... the height of the lake water (Volts) and the size of the hole (Resistance)... . The bigger the hole, the more water can flow through it. The lower the resistance (Ohms), the more water can flow (Amps) for a given potential difference (Volts). . However, the amount of water that actually flows through the hole also depends on the pressure, which is the height difference between the lake and the river. - So for a certain resistance, the current (Amps) is ALSO dependant on Voltage. . Therefore: the Volts, Amps and Ohms are all 100% completely dependant on each other using the formulas: Volts = Amps X Ohms Ohms = Volts ÷ Amps Amps = Volts ÷ Ohms . Summary Without Voltage, Current cannot flow. The higher the Voltage, the easier it can overcome a Resistance. So, whilst air has a high Resistance, a very high Voltage can jump across (arc) and cause a Current to flow. The resultant spark might not contain much Current (eg: Static Electricity) but can also be huge (eg: lightning).
@@johncoops6897 I'm still interested in understanding whether there are situations where you might combine extremes of the two for practical purposes? Significant potential difference but very low current or the inverse?
What a shame he has been banned by the UK national grid company.. simply not allowed to handle a mains plug anymore as he then has to serve the rest of his sentence. but he has promised he will be back DC style only, just with cars like Tesla cars, etc, as his court sentences are only in regards to mains ac. But the national UK grid company proof was solid, they could clearly see a disturbance in the force and a few days later there was a new photonicinduction video, so not much to argue about..

Best teacher ever. Should have been a teacher for electro mechanics
How do you know what to touch, and what'll murder you? Whenever you touch a thing, I get a twinge of fright. 😂
Pumpkin he would cirtainly be crisped if he had the ignorance of electroboom
Its been a year, but ill try answer it:
First off, you may want to not touch things far before it kills you. You did provide a neat line in the sand though, but its still not cut and dry who dies and who doesnt. So:
1) Generally, most damage is done to tissue by heat. Except for the criterium you put up; death. That one is most common from AC, that pulses the heart out of rythm, rendering it non functional and possible unable to reboot after the outside electric force is removed. Same applies to nerves/brain, up to an extent.
So apart from those, it is heat, resulting from a current running through us, with a minor resistance. And that will eventually, depending on how much it is and where it is, burn our cells = celldeath. And on top of celldeath, we get all sorts of systemic reactions which may also kill you.
2) In order for a current to run through us, the Voltage needs to high enough to overcome the blocking resistance we have. If resistance is too high, there will be no current = no heat = no burning.

3) But we are not consistent in composition. Even though people are anatomically 'equal', our body chemistry may differ quite some. And it will also vary in a person depending on conditions over time. So the current may run through muscle, or through vains, or along nerves, etc, depending on their conductivity at that time.
And if we apply the electrodes to our skin, a huge differnece there already is if we are wet or not, or even better; sweating.
Sweat contains a lot of salts, in a water solution. And that is a great conductor, while the skin itself (~dry) is more of an isolator. So when your skin is very dry, a current may not run at all, while when you are sweaty, it may run easily.

The the transformer doesn't heat up on short then why is it "Oil cooled"?
Because the welding jobs they're used for are longer than a minute.

What is the year of manufacture of this welder?
i know its not winter at the moment but i was wondering if when it is would it do anything if you put 30000v through the snow ? :)
Adding stuff == lowering the resistance. I = V/R .. lower resistance == more amps. You measure amps with the multimeter in series with the load btw.

Why do the welding rods in arc welders always melt at the tip as apposed to whole rod melting? Love your vids!
The hottest point is at the arc. The metal closest to that arc will melt. Eventually you use up the whole rod and snap in another.. If you were to just short circuit the welding rod at a sufficient amperage without producing an arc and just held it there, the entire rod would eventually heat up enough to become molten.
Lunarchy any idea why the arc is the hottest?
Zed1967 wow excellent answer thanks.. it all makes sense now.
what size of cable and fuse would i need to put this in my garage to play with ,and is the fun side ac or dc ??
*****
these are designed to be industrial ! and yes i do know what i am saying we used to make them !
Why not connect the stuff you want to fry directly to the variac? I'm missing something here
Variacs only going to give you 28A continuously. The welder will give you triple that. Good for popping things with a low impedance
I love that part at 4:15 to 4:24
Did this welder contain PCB or just standard mineral oil?
Also hope that you took proper safety precautions.
And what would you do with the oil after that? Can you just that it down to you local recycle facility and the are just going to take it and not asking anything about how you got gallons of PCB?
Bet he set it on fire in the backyard and vacuumed it up ;)
Long range arc welding
What's the rectifier for don't you only need that for DC things
want some? *hands some of the PCB oil and chips*
i just like the way you speak ;)
Wow so bright the camera can't even pick up the light at the end
Great video
Where can i get a oil cooled whelder? i cant find them aney where on ebay btw i live in the us if that helps
Photonic, i got a real nerdy technical question for you.
Regarding AC wire heat vs DC wire heat.
Why is the ratio 0.707:1 if both use equal amps and equal volts?
My classmates and i have been racking our fucking brains to figure this correlation out for a project. (We're in aviation maintenance school)
I hope it's mineral oil in those old welders...
The welder might be cheap, but a variac costs a bloody fortune...
Daniel's Game Vault true
Daniel's Game Vault welder still expencive £200 - £500
+Daniel's Game Vault Actually you can also get cheap old (and thus kinda bulky) variacs every now and then at a reasonable price too.
+Daniel's Game Vault I igot a used 10amp variac from ebay for like $30.
Yeah, i never understood why they are so pricey. the core isnt even special is just a roll of silicon steel with a single layer winding.
1:36 cracks me up
Everything's a breaker if you try hard enough
fuck man this was one of the funniest ones, huge fan, love you bruv
1:32 "it would prejuce . . . erm . . .*FUCK ALL* volts!"
Dude, I love your videos but I have questions - in lay-men's terms, what's the difference between lots of amps at no volts and lots of volts with no amps? What are examples of real-world uses for each? Thanks for sharing your knowledge with all of us!
2 years later, I will offer a reply...
First the answer to your question. The ultimate answer is nothing, because both are zero.
However, that's also not the ful answer because Volts and Amps are two different things. They only become useful when both are used together. If one is zero, then the other is useless. Only when both Volts and Amps have a non-zero value, then Watts (power) can exist.
.
Voltage is the difference between 2 points, where potentially some electricity could/might flow.
Current (Amps) is the *amount* of any electricity that is actually flowing (due to voltage).
.
Often an analogy of water is used... this is not a perfect model, but let's consider a huge lake, with a dam blocking it from flowing into a river below....
.
1. The *height* of the Dam is the potential difference (Voltage) between the dam and the river.
2. The dam itself is the Resistance (Ohms) to that water being able to flow from dam to river.
3. The *amount* of water that is flowing to the river is like the Amps.
.
If the water is completely blocked by the dam (infinite resistance) then no water will get into the river. It doesn't matter how low or high the lake is, the water cannot flow.
- This is like having a High Voltage against a high (total) resistance that stops it, so the Current will be zero.
.
If the lake and the river are the same height, there is no potential for water to flow. It won't flow down into the river because there is nothing to push it.
- So this is like having Zero Voltage, because there is no potential difference. No current (Amps) will flow, and the resistance of any dam doesn't matter.
.
If there is a height difference and then dam is suddenly removed, all the water will flow between the lake and river until they are the same height. While that water is flowing, it's a current.
- So if there is a Voltage and if Resistance is low, the electricity with flow at a "rate of" Amps until all the Voltage is gone.
.
OK, now let's make a hole at the bottom of the dam, allowing some water to come out. We have will a flow that depends on two things... the height of the lake water (Volts) and the size of the hole (Resistance)...
.
The bigger the hole, the more water can flow through it. The lower the resistance (Ohms), the more water can flow (Amps) for a given potential difference (Volts).
.
However, the amount of water that actually flows through the hole also depends on the pressure, which is the height difference between the lake and the river.
- So for a certain resistance, the current (Amps) is ALSO dependant on Voltage.
.
Therefore: the Volts, Amps and Ohms are all 100% completely dependant on each other using the formulas:
Volts = Amps X Ohms
Ohms = Volts ÷ Amps
Amps = Volts ÷ Ohms
.
Summary
Without Voltage, Current cannot flow. The higher the Voltage, the easier it can overcome a Resistance.
So, whilst air has a high Resistance, a very high Voltage can jump across (arc) and cause a Current to flow. The resultant spark might not contain much Current (eg: Static Electricity) but can also be huge (eg: lightning).
@@johncoops6897 Better late than never - thanks for the explanation.
@@TallmanMike - my reply above didn't give examples or fully answer everything. If you would like me to elaborate, just let me know.
@@johncoops6897 I'm still interested in understanding whether there are situations where you might combine extremes of the two for practical purposes? Significant potential difference but very low current or the inverse?
i could smell that aeresol can burning at the end...
Jon Holt I could have sore I smelled it too, lol.
De donde saca este hombre tantas cosa???
I do like the old school transformer better, the new wont last long before it goes bang!!
Why take the oil out? More cooling.
just take a lick of extremly hot plasma aka electrical arcing in this case to get a fire going
What a shame he has been banned by the UK national grid company.. simply not allowed to handle a mains plug anymore as he then has to serve the rest of his sentence.
but he has promised he will be back DC style only, just with cars like Tesla cars, etc, as his court sentences are only in regards to mains ac.
But the national UK grid company proof was solid, they could clearly see a disturbance in the force and a few days later there was a new photonicinduction video, so not much to argue about..
This is the kind of stuff you don't learn in school because the teachers would lose their jobs lol
I mean this isnt really education but enrolling in a electrical engineering major at a uni would teach you all this
got one like that too. mines a 3 phase welder though. D:
"couldnt resist putting a big spring across" lmao
One of your videos locked up my phone had to hard reset phone ....you was frying something ....then phone went to hell
Please explain the inverter wielder
Where did you learn all of this stuff?
he's a qualified electrician lol
With a lifetime of experience
He's actually an electrical engineer. :)
@@JayMark2049 PhD I heard
How many amps was that variac able to output?
