I like your rudimentary work, like stick welding and to repurpose thin copper wire into a multistranded cable. It's cheap but it achieve the same as the more expensive materials. 👌

Greetings from Finland!

5:32 The smile on his face 😂.
He is Indian Electroboom for sure 😅.

This is a project I've wanted to do next year, glad we can learn from your mistake (although I do have two microwaves as well in case I mess up :P) Thanks!

This is interesting, I have to wonder if it would be safe do so, to not heat the crucible, but heat the aluminium directly.

Having two rods in a cucible and the power flowing through the aluminium, kind of like the inside of a mercury tilt switch.

Hey Mr electron, I just found a shredder on the side of the road and it has a pretty nice dc motor inside of it with a gear system for high torque. You should get one to test

Nice project TX for sharing, be safe friend.

U can make CO2 as a shield gas to eleminate impurities from the metals... and TY!

When you do such arc-welding, in particular with coiled conductor wire spools in/near the weld site, add additional ground straps (from the arc welder) to the work-piece itself & run insulated grounding wires on the coils to a suitable separate grounding point. EM from arc welders can do a lot of damage coils of conductor wire.

Microwave oven transformers are typically only used for half of the AC cycle. There is the filament heater at around 6v and the magnetron cathode that is run through the high voltage diode. Those shims between the primary and secondary affect the inductance of the windings and reduce the current demand. These transformers are NOT designed to be efficient. The eddy currents lost from the welding of the EI core are not really important considering that these are only used for 20 minutes at a time max on average. The welds are to keep the core together and not tear itself apart instead of efficiency. Reuse of the motor windings with the enamel on it is a decent idea. But there are going to be kinks and thin spots that cause excessive heating inside the winding. And just please... Use an Old IEC connector from a power supply or wire nuts or something instead of shoving bare wire into an IEC plug.

you are crazy and so smart . i enjoyed and learned

이것은 변압기에 변경된 전압이 3v정도의 낮은 전압 입니다.하지만 그외에 전류가 굉장히 높아, 철도 녹일수있는것을 영상으로 보니 기분이 좋았습니다.

I would not cut the core, it's pretty easy to cut the secondary and leave the core intact. Plus, you put 3 weld spots (not spot welds), but the rest of the core might not make contact and thus will lose efficiency anyway. Plus those "additional cores that come preinstalled" are probably there to reduce the output power. Since you want more current at the output, I'd remove those. Hope this helps.

[KamoheloMoloi-otoc]

I love your project 👍👍 and can you please make a generator from a microwave fan motor with magnets.

[johnisbell]

The transformer cores are welded they way they so that the core will saturate and self limit as a safety precaution.

[tewodroseleulseged]

Can we use it to weld copper with copper

[kotarisrinivasarao]

How you prevented should while you are touching molten with hands

[digdugboy]

What was the resistance of your primary windings? I disassembled a microwave transformer today and measured only .3 ohm resistance on the primary side.

[hetrajraulji]

Can i add 1phase variac at primary side and get variable current secondary side ??

[vincentvincent]

Multi enamel parelel wire can avoid eddy curent loss

[ghlscitel]

I have an old 120 A welding transformer.
I might do the same thing with it I hope to get more than 450 A
