How To Make Simple Pencil Welding Machine At Home for soldering | practical invention 

Yup, I was going to say the same thing

But making if more cheaper and fun

You missed the whole point, wow, over the head.

Some people in third world countries and countries like cuba don't have the luxury of just buying something whenever they needed. Take your negativity somewhere else please

That McGiver ain't he something 😅

Yeah this must be a joke... Finding that part is more work/time/money than buying a cheap soldering iron and that pencil will burn up in no time. You'll be holding hot graphite.... If that works at all...

💀💀💀💀

😂😂😂😂😂😂😂

Graphite had a high resistance, and therefore, it creates a lot of heat.

@@FrazierDanger ok, and that heat conducts down the copper and melts the solder. Why isn't that heat conducting down the wires and melting the insulation? Those power supplies are usually 5v ~2a, so you have around 10W max. Low quality soldering irons are 70W and don't melt solder that well. You can also burn wood with soldering iron tips, so if the graphite is hot enough to melt solder why isn't the pencil smoldering?

​@@southy3667I agree. It does smolder some when he plugs it in. Tht has to be from wires and insulation and who knows he may have built more than 1 unit for video. Deff dangerous. Buy soldering iron at harbor freight

It just amazes me that the pencil lead doesn't just break, especially when you tighten a screw down on it, any time I sharpen a pencil with a knife the lead ,graphite always breaks.

​​@@FrazierDanger copper has a high thermal conductivity and hence conducts a lot of heat. Which means the USB wires will heat up a lot which was the point they were making, why can the tip reach those temperatures but the USB wires aren't?

Yes

It's a type of splice

А у меня как раз сварочник получился, я брал не карандаш, а гранулированный графит , и вместо проволоки - кабель ВВГ.
