In USA, standard outlet power is 110V, which is low for this application. All the appliances that need to draw more power work on 220V (electric ranges, dryers, heaters, EV charges). US houses are wired for what is widely called split phase 240VAC, on two hot legs (1 & 2) and Neutral at the center tap. The neutral is referenced to earth at the breaker box. For most outlets in the house, either leg 1 or leg 2 is used together with the neutral line to provide 120VAC for most small appliances with a plug-in cord. The two legs appear to be 180 degrees out of phase with each other if looked at simultaneously which provides 240VAC. So you need one SSR for each hot leg. In Europe 220V is on single hot leg and hence you need only 1 SSR.
By far the best Non Weld Heat Treat oven I have ever seen. Nicer even than a lot of welded versions. If you ever decide to make more and sell them - let me know.
You all probably dont give a shit but does someone know of a way to log back into an Instagram account? I stupidly forgot the login password. I would appreciate any tips you can give me.
Awesome video !! 3 years later and still going strong. I live in the. i looked at comments and you talked about the 200v at each leg and US has 120 at each leg. So using in your calculation 120 sq. is 14400 / 3200w would be 4.5. Resistance I would use would be using would be 4.5 R. How would I figure the length of wire to coil. The only way I think to figure the length is by using wire diameter per length of resistance.
this is the first time ive seen making coil element in paralel system. & it looks great. i've made one element from stainless steel wire, 240 v, 3200 watt. but it takes very long to reach 800 c & it wont make higher again. i think i should try yours. but i still dont get it about 2 SSR. Is it okay if i use just 1 SSR? cheers from indonesia
Electric system in US is 110V, but it comes into homes with 2 hot legs being out of phase with each other. So to get 220V in US you need 2 hot wires, each at 110V and as a result need to get 2 SSRs, 1x for each hot wire. In other parts of the world (Europe for example) 220V comes in form of a single hot wire at 220V and a neutral, in this setup you only need 1 SSR. I'm not sure about Indonesia, I'm thinking you guys are 220/240V.
What sheet metal did you use. Is that aluminium or steel ? Also the thickness please. Also would you feel safe enough to let this run for 5 hours straight? What is approximate temperature outside. I am aware temperature outside will be dramatically different in different places. I am wondering on the maximum temperature.
The metal is Galvanized steel. thickness is 0.2mm, if I had easy access to thicker metal I'd use that. I ran it few times for more than few hours straight to anneal 1095 steel which came hardened, no issues, I think the trick to safety is in getting good quality SSRs. For the max temp I took it to 2000F few times, didn't try to go any higher, but it's possible.
@@swaroopcool22 As oven runs outer shell gets warmer and warmer. In and hour or so it gets uncomfortable to touch, i didn't measure how hot it gets exactly.
I don't understand your use of the two relays. It seems like all of the current is going through both relays, so what is gained by switching both of the hots? In my electric furnace, I plan on using two 120v circuits (so my coils will be electrically isolated), so I needed two relays. I'm an engineer, but not electrical, and I'm not very familar with with 240 v circuits.
Rich, 240V in USA operates with 2 hot wires, hence 2x SSRs. 120V is between one of hot feeds and Neutral, 240V is the voltage between 2 hot feeds. This video explains it well: th-cam.com/video/iby2wDNFk6o/w-d-xo.html
@@cantsitstill9056 Thanks for your quick response. I skimmed through the video, but didn't notice anything regarding solid state relays. I'm still not following. I understand the need for double pole circuit breakers on 240 circuits, since you are trying shut off both hots to the ground or neutral, but I'm not following the use case for your circuit. Any other suggestions for an explanation?
@@richdobbs6595 Solo PID controller doesn't have it's own relay to control AC supply (some models do, but not 2x of them). So SSRs are used to take Controller DC signal and turn on/off AC current into a coil.

Great video. But if you add music to your videos it can't just be a five second sample on loop for twenty minutes. You're killing me bro
Hi man , nice work !!! K saw other video of this project and some use only One SSR and some 2 SSR , can you explain me why didd you use 2 of It ?

What were your measurements for the hinges? I’m trying to guess but I’m not sure. Great video I’ll be linking to it from my video.
they are roughly 2" x 3"
Amazing piece of work sir! What's the diameter of the high temp wire you used?
Nice Build! Im curious as to why you rounded the corners? Aesthetics? or were you concerned a thermal buildup at the corner?
Corners rounded to make it easier for a sheet metal wrap.
Great video sir... I'm going to need to build one of these now.
Please do a video when you make one!!

your level of genius on that pipe clamp method is unmatched. im absolutely blown away thats smart as hell good job man.
Thanks
isn't getting hot outside? There no insulation on the bricks just sheet metal.
But that annoying sound playing the whole time though
This is AWESOME. Any chance of a link of parts and instructions?
Check description, parts are there now. The video itself is an instruction :)

If memory serves me I figured out length by trial and error using ohmmeter.
please tell me no working power supplies were harmed in the making of this, even if it's a lie :(
LOL :)
Why do you think it will still be 18 Ohms under full temperature?😂
cool project...nice
How do you prevent electrocution?
Check minute 53, the switch attached to the door would disconnect power when door open.
That's clever

@@cantsitstill9056 thanks im a moron lol
great video, how many feet of 22g resistance wire? Approx...
It was less than a full roll of 100", I'd say around 70" or so.
Having a super hard time figuring out a 3 wire 240v setup here. Could you help me out?
Sure, how can I help?
Why are 2 relays ?
In USA 240 volts comprised out of 2x 120 V wires, 2 relays for 2 wires.
What is temperature of the metal flashing on outside of unit when inside is 2000f?
Unfortunately there's no simple answer to this. Outer shell temperature is rising slowly with the time, it's not constant.
I want to buy
Could you give me a rough estimate of what the total project cost was.
My cost was ~$300

@@cantsitstill9056 how about external temperature of the metallic cover. Since you didn't use ceramic wool isn't it too hot ?

How did you put screw through the brick? My bricks don’t grab the screws. Did you use cement?
I put screws through metal flashing and bricks, and yes tried to inject as much cement into screw whole before driving them in for good.
@@cantsitstill9056 ya I did that and it worked now
what is the model of the temperature controller ?,

The thermocouple is K type?

Hi, this is great! Can you tell me what is the maximum temp it is capable of reaching?
I got it to 2000F, but I'm sure it can go further north.
Great stuff!
Glad you enjoyed it
