From my understanding, it is actually a working spot welder, but WOW; I wouldn't have the intestinal fortitude to put power to it.

As long as a transformer is used, it should be OK according to AAC safety rules. So go on just try it

 

Nah, it needs an LED to meet out standards. John

 

Looks like some sturdy "magnet wire" they found.

It appears the individual laminates aren't insulated from each other, so the output is likely sub-optimal.

 

... so the output is likely sub-optimal.

Ya think?

 

I remember that thread. I don't think it would pass current muster.

 

Found pictures of it in action.

I am guessing Africa for location, some creative things from otherwise junk over there.

 

Nope, good old Georgia USA, I think. Wookie would remember him, those pictures are from this site. Reason I mention Wookie is the guy was also a former marine.

It was about a year ago.

 

Bashing some kit together FO SHO.

Theory has its uses, but application in abysmal conditions is no small proof of mans genius in engineering.


Also, I don't think the surface to surface contact between the steel sheets has the effect of 'shorting' them out electrically to the eddy currents. I'm sure I read papers on studies that showed even the lightest of oxidation layers, on the surfaces, was sufficient to reduce eddy current flow by several orders of magnitude.

Hello,

I remember the thread well.

It's like those company's that has budget cuts.

Why throw 'em if u can us 'em.

I remember the guy pointing it tht Maldivians uses them. The nerve of that ....
He thinks he is better than all of us put together. What I think of him is he is naive then the least experienced member in AAC

But seriously tht TX could use some industrial bench vices to hold the core
