LOL.. I found directions to make a carbon-arc furnace in an old 1950s "science & engineering experiments for kids" book back in the late 80's. It told you to get carbon rods from old dry-cell batteries, crimp them in lightweight curtain rods, and use a terra cotta flower pot as the crucible. And the best part? Just wire it directly to your house AC mains power with a cut extension cord, using a glass ash tray, salt water, and lead fishing line weights/sinkers for a rheostat. 😂 Of course, being the smart kid I was, and that nobody in the family smoked, I would just use a spare dimmer-knob light switch in the house workshop as that was a factory made rheostat. And would obviously be far superior to some janky thing made with an ash tray, lead sinkers & salt water. I did actually strike an arc, for about 5 seconds. Then the dimmer switch melted. 😅
This is indeed an unforgettable experience, but I do not recommend using a sliding rheostat to control the power of the load. It can be used when the load power is small. The resistance will consume most of the power and cause serious heating. The use of a transformer solution is much more reasonable.
Using a welding machine to melt the metal is not as efficient as using a toroidal transformer wire coil, I have a project where a used converter transformer is converted and a copper wire coil is added 20mm With a total of 38 coils using carbon anodes as the electric arc

A bit more code for the welding process Ah, a hollow rod would be best, as then de-carbonization can be achieved and a nitride hard steel can be produced... also titanium can be added with an argon flow. I assume you are using tungsten rod and this would be best for an add on to an existing electric furnace.. waiting for your upgrade. Happy grinding of the casts.
Thank you for your encouragement. In fact, that rod that looks like metal is actually a rod of graphite, but with a layer of copper deposited on the surface!
No bro. All arc in furnace are above 3000 c. 3000 f won't melt steel bolts that quickly. I have same at home with carbon graphite rods and tungsten rod. Mine eats the carbon graphite rods. I have to use tungsten rod instead
Yes, that is the ambient sound. In theory, I can use audio processing software to reduce the noise, but based on my research, keeping appropriate white noise in the video can make people relax and calm down, because when people can hear white noise, they will psychologically feel that the whole environment is very quiet, and even feel immersive. This is why I would rather use white noise than add background music to create an atmosphere because that will make people feel bad. In recent years, this natural creative method has also been popular among UA-camrs. And you noticed this detail. I think you are also engaged in the audio-related industry, right? Because photographers will take the picture details of each work seriously, while music or sound effects engineers will focus on the sound details of your content!
Yes! This welding machine is very cheap, with a power of about 1500 watts. If it uses three-phase electricity to work, I can use it to smelt scrap iron, but considering the cost, I will not do it!
Gute Experimente. Besonderer Respekt gilt dem automatischen Lichtbogenzündsystem. Aber die Leistung reicht aus meiner Sicht nicht aus. Ich habe erfolgreich mit einem Industrieschweißgerät mit ca. 70 kW Leistung experimentiert. Carbonstäbe mit einem Durchmesser von 50 mm. Strom von 300 bis 1000 Ampere. Spannung von 30 bis 60 Volt. Dafür ist jedoch ein industrielles dreiphasiges Stromnetz mit ausreichender Leistung erforderlich.
Pretty cool project! Nicely done with that high voltage arc start and height control!
Thank you for your encouragement, I will make more interesting videos in the future

@@free_time_g Transformer must be used simply because of safety. The rest isn't even matter.

Bravo.......carbon arc light........great job......cheers
Thanks for the encouragement, I will continue to do some interesting projects
I so badly want to make one of these furnaces! I want to try making high entropy alloys at home 😅
Could you share how you made it with me? I want to make one for myself, but I don't know where to start. please
Looks pretty cool, great job!
Thanks
Ciekawy projekt!
dziękuję za zachętę！
I would like to build one of these, do you have any schematics or videos of you making one? I wish I could just buy one somewhere, honestly

Cool contraption, I just use my hand, it took a lot less time to build.
Can you help me to make this one

are you sure this go up to 3000c??? maybe you mean 3000f
yes its sure 3000F, else if it will melt the house lol
for sure 3000C i melted aluminum oxide with this type of furnace and that melt at 2200C

I work in a steel making company and Iwant to make a mini EAF like yours
Hello sir, are you planning to make an electric arc furnace like mine? I'm afraid this requires some electrical skills because it is dangerous.
that poor welder is not designed to work at 100% duty cycle, it will give up soon if not given adequate cooling period
at full amperage yes, but at 25% it more than likely should be okay
If not, he looks like a guy who would be able to install water cooling for the welder.
The temperature of the carbon rod is very high and water is needed to cool it down, otherwise it will burn out my machine
Yes! This welding machine is very cheap, with a power of about 1500 watts. If it uses three-phase electricity to work, I can use it to smelt scrap iron, but considering the cost, I will not do it!
If it gets hot use two

Yes, mine is a household appliance, it is not powerful enough and can only melt some small pieces of metal!
больше распыляет металл , чём плавит . НО работа проделана " моё почтение"
Yeah, I just do this by hand, and I heat it from a distance so that it doesn't vaporize the metal so fast.
Coper roaches 😂 looks like you definitely need an IR filter lens.
Yes, I removed the infrared cutoff lens of the phone camera module.
