Any electricians here? Need some help
    #19830570 - 04/11/14 10:14 PM (9 years, 11 months ago)

I purchased this skillet heating element with the intention of being able to head up an external piece of metal. However, the protruding rod doesnt heat, it must be a temperature gauge or ground?

There are two female inserts on either side of the center rod, which I have now figured is to attached to the piece of metal being heated. MY question is, if I insert a loop into these inserts, will they effectively heat up? Or am i missing  a ground somewhere? Do I need to connect the loop to the center rod as well to avoid shock?

if you stick a piece of wire between the two it will cause an explosion, burned fuses and possibly a fire... metal is not a heating element.

edit: don't kill yourself with electricity, buy something pre-made.  :shake:

edit edit: what you have there is an adjustable power lead, not a heating element.

The heating element designed for that device has a very specific resistance that will limit the amount of current the circuit will draw. You put a piece of metal in there and you have a short circuit.

The rod is definitely a ground.  The heating part of a griddile is in the griddle (some type of resistance) not the plug. Don't fuck yourself up.

there is no ground... look at the plug. It is just a guide for plugging the lead into the skillet.

I believe the part that sticks out is indeed a temperature probe.

OP, if that piece is all you have, you don't have a heating element. You basically have a thermostat. The heating element is in the skillet part.

right so here is a makeshift heating element, basically a bent piece of metal that creates the loop. Someone said this wont have the same resistance as the piece made for the module.

So if I plug this in, its pretty much gonna explode, and not heat up?

just get a few DC batteries, enough to get some good AMPs and some cheap but think gauge copper wire. Wire the batteries in Parallel to increase AMPS and you can get that wire pretty hot and no risk of short circuiting anything, but you might start a fire.

if its not a high conductive metal, plug it in on the lowest setting some where fire and sparks wont matter. basically in a "safe zone" and see what happens. except for potential melt down and sparks the worst that will happen is a breaker will trip.

heating elements have a high conductive resistance. that pic looks like aluminum or steel, witch has a LOW conductive resistance and is NOT GOOD.

if you decide to plug it in keep the device where it has ABSOLUTELY no chance to catch any thing else on fire. there is a good chance it will flip a breaker if any thing is wrong.

metals like iron have low conductivity and are better for a heating element.

basically what i said in a previous post of yours on this but i got degraded and called stupid.

you could use a ac to dc converter so you dont need batterys but thats tricky business if you dont know exactly what you dealing with.

That looks like stainless steal don't use stainless. Use good old fashion steal . Stainless releases all sort of nasty when it's heated.

Perhaps you mean "steel".

That's pretty bad advice. If you use thin wire, the wire will melt (and may cause a fire that way), if you use thick wire, the batteries will short and catch fire/explode.

Yes, but it's unclear how much power the thermostat (the thing with the turning knob) can handle, hence, it's virtually impossible to work out what length and thickness of which sort of metal you'd have to use. If you are bent on proceeding with this, make sure you use a socket that is connected to a circuit breaker (fuse) and use regular, not too thick iron wire. Iron has a higher resistance than copper, so you'll need less wire to achieve your goal. Copper wire could be used too, but is unnecessarily expensive for this application and you'd need more of it. But all considered, I'd advice against this.

What is the application that you have in mind? Perhaps we can suggest a safer method to achieve what you're trying to do.

OP... DO NOT FUCK WITH ELECTRICITY! YOU WILL KILL YOURSELF AND OTHERS!!!

Go to tech, read some websites... don't ask the stoners on shroomery, go to electrician websites. Buy a pre-made unit, buy insurance already.

It's not like if your grow fails you try again... If it fails you die.

That's why you use wire that isn't too thick or thin.. Used to do this ALL the time as a kid... Never had a battery blow up. You need thick wire to wire the batteries together, but you can coil wire to increase the temp within the coil.

Sure, you can balance your way into a stable situation, but the trial and error process is quite tricky. The best approach would be to calculate the length and thickness of the wire needed to achieve a stable heating situation instead of just guessing and ending up with a hole in your workbench or burning lithium all over the place :wink: So I'm not saying it can't be done, but it's just too risky of an approach IMO.

You should probably measure the resistance of a heating element to get an idea of what you should be putting in the circuit, but as a general idea with a 120V  you'd want something between 50 and 100 ohms to draw no more than a couple amps, which is probably all that device is capable of.

I think most elements are made out of ceramics or fairly poor conducting alloys.

Exactly.

All I know here is that heating elements are made of tungsten because it create a lot of resistance which makes it heat up.

Also, to everyone interested. I am planning OPs funeral, everybody is invited.

Koods said it already, the element is specifically designed to match the output of the thermostat.  The resistance will determine how much current will pass through it given a specific voltage.  It is designed to take ~120v through a polarized non-grounded plug, so there is no ground involved. 

The picture of the two pieces of metal sticking out of the thermostat shows a short circuit, and assuming those metals will conduct electricity, will almost certainly trip a breaker or burn a fuse as well as create an interesting and alarming fireworks display at the place where the metal rods are making contact because of the surge of current that will happen.

My intention is the most simple thing ever, yet I cannot find a solution.


I want to be able to heat up a small piece of metal (like the size of a quarter) to a range (adjustable if possible) of 130-165 degrees Fahrenheit and keep it at that temperature. That is it. Thats all I need.

At first when I bought this thing, I thought the middle metal piece was what heated up, but its a temperature gauge. I am not going to proceed with this experiment, as this is dangerous and im in over my head. but FUCKING A... ALL I NEED IS TO HEAT A PIECE OF METAL TO 150..... I havent found anything capable of completing this task.

A quarter weighs a few grams; whipping out a heating solution that will apply in excess of 100W to it will be overkill and it will make temperature regulation quite challenging.

Why don't you just take a 15W light bulb (the old-fashioned tungsten kind) with a fixture, put it in a little aluminum box and suspend the metal piece above it so that it heats up to the required temperature. You can vary the temperature by choosing to poke some (more) ventilation holes in the aluminum box and by varying the distance between the metal piece and the light bulb. Heck, you could easily make an aluminum box this way that heats to the desired temperature in its entirety.

The worst that could happen in this solution (if you properly shield the wires that feed the bulb) is that the bulb burns out, which it will do at some point, obviously.

If you want to get fancy and satisfy that urge you have to fuck with electronics, go to radio shack and get one of those big watt sized resistors with about 5-10 ohms resistance. Yon can easily find a proper low voltage that will heat it up to whatever temperature you wish

That's the way to go.

Use one of these TO-220 resistors with a metal back (like this)

Thanks guys, I'm gonna hit up radio shack and see what they've got to offer :smile:

You have no idea what you're doing.  None of the wires suggested will work. You're just going to flip a circuit breaker in your house or possibly cause a fire or even electrocute yourself.  Heating elements are made from Nichrome wire (nickel-chromium alloy) which not only has a certain resistance, but has a certain heat resistance curve. Don't be going around plugging in random wires or metal tubes into electrical devices or you're going to figure it out the hard way.  as little as 10 micro-amps of current through the right internal organs can kill you. 110VAC probably won't kill you but it could.

If you want to get fancy and satisfy that urge you have to fuck with electronics, go to radio shack and get one of those big watt sized resistors with about 5-10 ohms resistance. Yon can easily find a proper low voltage that will heat it up to whatever temperature you wish




That's the way to go.

Use one of these TO-220 resistors with a metal back (like this)

:laugh2: So your plan is to run a tiny resister and a wire in series and see what happens?  I assume you're going to attach that resistor to the coin, but do you know the output of that device you have?  It was meant for a nichrome wire and it's going to fry that little resistor I bet.

If you can find some nichrome wire you may be able to make a circuit that works for what you need.  That unit you have is probably just a rectifier (AC to DC converter) circuit with a rheostat (current adjuster) You could get a digital multi-meter and measure the DC voltage output then use THIS to calculate the size nichrome wire you need for your application. 

Or you can just put the coin or whatever on an electric stove top and measure the temperature with a laser thermometer.  I don't know what you're trying to do so that's the best I got for you. :shrug:

All I know here is that heating elements are made of tungsten because it create a lot of resistance which makes it heat up.

Also, to everyone interested. I am planning OPs funeral, everybody is invited.
