The problem of a reliable and durable connection between various metal parts is relevant both for large production processes, private workshops or service centers, and for the household needs of those who like to do everything with their own hands. Semiautomatic welding machines from the online store Bulgarian.ukr have the widest application and perfectly cope with the task of welding ferrous and non-ferrous metals, as well as various brands become. For those who have thought about the need to master this device, we will tell you about the principle of its design and operation.
How the semiautomatic welding machine works
The semiautomatic welding machine is a compact electromechanical equipment capable of operating from a household electrical network. The role of the electrode melting under the influence of high temperature, forming a connecting seam or cut, is performed by a special wire installed on its cutter. The standard kit includes the following parts:
- Device block in a protective case, which contains a current transformer and connectors for the torch and electrical cable.
- Directly a sleeve (made in the form of a hose) for a welding device.
- A torch (torch) into which a special wire (electrode) is installed.
- Conductive cable and earth clamp.
- Reducer, connecting hose and inert gas cylinder.
The welding process is as follows. A torch with a wire (electrode) is installed at the junction of two metal parts (future seam). Due to the influence of voltage between them, an electric discharge is formed, the simultaneous supply of an inert gas to the heated section prevents the formation of oxides, and during the cutting procedure "blows out" the hot metal, making the cut smoother and more accurate. For some operations, it is possible to carry out work without using gas.
The device got its name "semi-automatic welding" due to the fact that the wire (electrode) is fed to the place of processing by the torch in automatic mode, and the direction and speed of the operation are set directly by the welder.
