DANGEROUS !
There is the risk of getting an electric shock. Details are under mains voltage of 220 volts. Bare hands do not touch the electrode! All the actions in this video are made under the supervision of professionals. Sometimes you need something urgently to weld and svarochnika you do not have, what do you do? There is a way! You can build it yourself! This does not require complex parts and extensive experience.
You will need: a wire with a fork, water tank, water, salt, two metal plates, and directly the welding electrode. Pour water into the jar and add back two tablespoons of salt. Screwed to each plate on the wire. Immerse the plate in a salt solution. By varying the depth of immersion the plates, can change the current at the welding electrode is in the range from 10 to 160 amperes. Connect the wire from the first plate to the welding electrode on the second plate to the phase conductor is 220 volts. The neutral conductor of the network to connect to the details of which will be cooking. To determine without display where the phase of the network, and where zero, just touch Exposed wire to the ground and see the wire that is in contact with the ground sparks, he is under the phase voltage.
But this scheme is not without drawbacks:
1 - welding electrodes and some parts are under phase mains voltage, so you need to be very careful.
2 - large consumption of energy, if you have a weak network, the neighbors will be blinking light.
3 - a big load on the wiring. If you have a wiring is not designed for high currents, it is best to connect bypass wiring. Our channel video about an unusual experiment with electricity, experiments and inventions. Here we share new ideas, different from the usual thinking of the majority.
