The method of metal processing (cut, connection) using electric welding is still in demand not only on an industrial scale, but also in the private business sector or even at the household level. Today buying a semiautomatic welding machine is as easy as a set of locksmith tools, and why semiautomatic devices are in high demand we will tell you in more detail.
The principle of operation of the semiautomatic device
The main distinguishing feature of a semiautomatic welding machine from equipment using the electric arc principle of operation (the role of a torch or a fastening element is played by an electrode) is the addition of the operating circuit by supplying a gas that increases the combustion temperature:
- Instead of the classic electrode, a wire is used, which is fed automatically as it burns out.
- The voltage for heating the electrode is supplied through a transformer.
- An inert gas is supplied to the place of action of the heated electrode on the metal being processed through a special nozzle.
It is the heated gas that becomes a kind of cutting tool, while the quality of the weld is significantly increased and the formation of scale, as well as oxidation processes on its surface, is excluded.
Additional features of the semiautomatic device
As an additional bonus for those users who have opted for a semiautomatic welding machine, it is possible to use it without connecting an inert gas torch. To do this, you will need to set the appropriate operating mode in the device and replace the electrode with a special flux-cored wire. The gas mixture required for welding will be formed in the form of vapors from the flux wire heated by an electric discharge of a given power.
You can get more detailed information about the technical capabilities of welding semiautomatic devices using the website of the company that supplies and sells them on the domestic market. The online catalog of the resource presents various models from the simplest “amateur” ones to more complex and multifunctional ones for professionals.
