Welding machine

Of course you will not weld with such a welding machine in everyday life, but for a hopeless situation you will surely help out. And besides, I have not yet seen a simpler device. . .

As you can see, it consists of only three batteries and thick wires. Electrodes are not very 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 intermediate cables shorter and thicker, and throttle the throttle in series. The simplest option is, for example, a core from a 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 spray gun ...

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

  It’s funny, that’s a constant current does not go through it? The inductor in DC welding machines is used to maintain the stability of arc burning by maintaining the stability of the current when changing, for example, the distance between the electrode and the surface being welded. Well, if briefly.

  Yuri you need to get acquainted with the transient process on a reel

Thick wires ... Electrodes of not very large diameter ... In fact, the wire has a cross section and the electrode has a diameter. Although, it’s alright))

Nothing ... But such a design can not shy away! God forbid, one or two holes of drainage holes in the battery are clogged! .. With short circuit (welding) there is a big load. Accordingly, there is a large emission of hydrogen in the battery. And if the hydrogen content in the confined space becomes more than 2%, then such a frail explosion is not frail! Be careful!!! 15 years ago, I almost lost my eye ... I managed to rinse my eyes with water in time.

  Hydrogen from batteries is released when charged.
