Welding machine

Electronics / DIY electronics 109 389 10

Of course, you won’t weld with such a welding machine in everyday life, but it will definitely help out in a hopeless situation. And besides, I haven’t seen a simpler device yet. . .

As you can see, it consists of only three batteries and thick wires. The electrodes are not particularly large in diameter. But for welding medium-sized objects it is quite suitable.

There is also a significant plus - it works without an outlet, which means you can cook anywhere!

The idea is far from new. Make the intermediate cables shorter and thicker, and insert a choke in series into the circuit. The simplest option is, for example, a core from the network transformer of an old TV with as many turns of the same cable as possible. The arc will be much more stable.

  Without a throttle, this is not welding, but a squirter...

Is it okay that the inductor only works in AC circuits?

  Funny, i.e. no direct current flows through it? The choke in DC welding machines is used to maintain arc stability by maintaining current stability when, for example, the distance between the electrode and the surface being welded changes. Well, that's it in a nutshell.

  Yuri, you need to get acquainted with the transient process on the coil

Thick-core wires... The electrodes are not particularly large in diameter... Actually, the wire has a cross-section and the electrode has a diameter. Although, it will do))

Everything is fine... But such a design can easily shy away! God forbid one or two holes in the drainage holes in the battery are clogged!.. During a short circuit (welding) there is a large load. Accordingly, there is a large emission of hydrogen in the battery. And if the hydrogen content in a confined space becomes more than 2%, then a rather serious explosion occurs! Be careful!!! 15 years ago I almost lost my eyes... I managed to wash my eyes with water in time.

Since ancient times, field repairmen have used 4 tank batteries. Of course with a normal cable. And this garbage if you only unsolder the network boxes.....
