HACKED!: Microwave Transformer becomes a High Current Transformer

  1. Sir; your videos are so well done and clear that you should be given an award for Teaching. You're one of the best on YouTube. Thank you.

  2. The AC current requires AC sticks. They help keep the arc ignited during polarity change.
    60 amps is enough to weld thin stuff, so I think your issue is either the stick or that when the current starts to flow more you have greater back EMF.
    On the secondary side, adding an inductor, then full bridge rectifier with choke on the DC side may fix this.

    For a home made version I found with a diagram that uses this technique.

  3. Думал, чел реально с одного транса сварочный соберёт. А вышло шляпа(((

  4. Dumb engineers be like

    Please stop being a moron

  5. Do you use a smaller wire I used smaller wire made one use two transformers together in parallel and my welder works just fine it will will quarter-inch steel you're using too thick of a wire and you're not getting enough windings

  6. I love your videos but DUUUUUUDE! DON'T FUCK WITH MAGNETRONS! they contain some naaaasty shit like beryllium (can't remember if pure or in a compound but I do remember that they are super crazy carcinogenic and toxic). Please be safe, you're too valuable to the world.

  7. Great Scott please tell me what you studied in college? What is the course called? I want to know all the things you know!!!

  8. But why you didn't first tried to flip the transformer. So to that on secondary side you put mains voltage (230v) and on primary you must get around 27 volt.

  9. Why did you replace the secondary? If you replaced the primary and ran 230vAC through the secondary, wouldn't the turn ratio be higher and thus more current?

  10. Does anyone know why my transformer heats up even without any load on a secondary side? What resistance suppose to be on a primary winding?

  11. You tried arc welding with high current whereas high current is for resistance welding. (And high voltage for arc welding)

  12. Try to use 2 transformers in series with 35mm wire, you should be able to get the desired voltage and current for the welding!

  13. Dear Scott: You mentioned that the output voltage of the 2nd design is about 8 volts. My late husband was an auto mechanic and in his shop the arc welders ran around 24 volts. I am suggesting a 24v design. Hope this helps.

  14. The aluminium electrode you were using is a you filler rod.
    Make sure you have the father around the right way.
    If you are stick welding. That's what you called the pencil electrode you you need DCEP. ELECTODE POSOTIVE aswell as an argon gas.
    The stick electrode is made for steel not aluminium.
    The filler rod is made for welding alaumoniu. At a DCEP.
    WITH a argon gas shield. .

  15. True. Transformers are great if you want to transfer high voltage and low current into low voltage and high current, but voltage ranging 35-45v and DC power is necessary for proper welding. We all make mistakes. But we must realize it, and next time we don't make them.

  16. If the resistance is constant, higher voltage means thinner wires, aka less current flow; low voltage means thicker wires, aka high current flow. Welding is based on making the metal plates we weld have bigger resistance, than the transformer itself. Bigger resistance will automatically result in heat generation, and we successfully weld plates.

  17. Hello sir,
    Sir, will definitely give this 220-volt AC how it can run in this direction, it does not burn

  18. But people it is obvious, the DC is always used in welding. Simply. The AC has got 50/60 herz in it and this kind of current is made to flow through environment that has large resistance with small amounts of heat generated.

  19. The courrent is AC
    For soldering the better courrent is dc courrent.
    You can convert ac from dc with a big diode bridge, (Over 100 A) and reapeat that experiment

  20. Two years later, I dare giving my 2 cents:
    Aluminium oxidize so fast in 20% concentration that it is impossible to do.
    If you apply enough heat to melt it, then it burns violently, like clearly seen with thermite.
    Using an oxygen concentrator, I was able to burn aluminium cans… But only by moving the source of oxygen constantly.
    When a bright and hot part of the can start burning, the aluminium oxide layers blocks further burning.
    Argon is the friend of aluminium welders. Helium is too light and cold.

  21. Very rare video of failures. That saves a ton of time for others who want to do the same. And this is a valuable lesson. Thanks for posting.

  22. Are you sure you cut the secondary and not the primary ? Usually the primary contains more turns than the secondary: V1/V2=n1/n2.

  23. You should've wound the two transformers in parallel and should be getting a current between 80 amps to 180 at least

  24. I'm a bit late to the punch, but you can wire two car batteries in series. Use that trick on the trails to weld broken axles. Works pretty darn good
