Radio fans are interested not only transistors, condensers and chips. They often need such device as the welding machine. It is quite simple to bring together him by the hands. Let's note, industrial welding machines have the big size and weight.
Instruction
1. Many people are interested in the figurative welding machine assembled theby hands. Such device weighs only 26 kilograms. Industrial devices need the power voltage equal 380B. It is quite inconvenient and also is unsafe. The weight of the welding machine generally depends on transformer weight with the E core.
2. For production of the welding machine it is necessary to take two cores from the laboratory autotransformer / LATR/. Let's note, the core at it round and is similar on steel band which forms the core. The hole of bagel has to become more. Now it is easily possible to place the primary winding of the transformer in it.
3. In order that area of cut remained invariable, it is necessary before establishing winding, to reel up the removed part of steel band on outer side of the core bagel. The wire for windings needs to be selected from calculation that current of welding equals 80 A. Thus it is possible to make welding by three-millimetric electrode. As a result quite compact and easy welding machine turns out.
4. Further it is necessary to achieve that there was smooth regulation of welding current. For this purpose it is necessary to change secondary voltage. In industrial welding machines the voltage control is carried out quite roughly, stepwise, by switching of windings. For regulation of welding current it is gentle to install the scheme of straightening of tension on the welding machine. At the output of the device there will be straightened adjustable tension, up to 50 V. These data allow to use the device for accumulator charging.
