Welding is the most popular way to connect metal parts, which is distinguished by reliability, strength and durability. Welding is carried out using special welding equipment, which is used both in production and in domestic conditions. In order to choose a welding machine with the necessary functionality, it is necessary to study in detail the types of welding equipment and its operation parameters.
Types of welding equipment
one. Welding inverters are direct current units, the voltage of which is straightened at the output, and then converted into alternating voltage, which enters the transformer. The welding inverter in Ukraine has a low weight, compact dimensions and small dependence on the input voltage. Today you can buy a welding inverter in Ukraine in an online store where prices are much lower than market.
2. Transformers – units that are characterized by simplicity of design, high reliability and affordable price. Transformers are unpretentious in operation and are mainly used for welding of ferrous metals both in v and overlapping and overlapping. To work with transformers, melting electrodes with special route or fluoristo-calcium coating are used.
3. Rectifiers are an analogue of a transformer that has similar design features. The design of the rectifier is much more complicated and heavier than that of the transformer. But direct current provides more comfortable and stable operation. With the help of a rectifier, you can weld both ferrous metals and stainless steel and non -ferrous metals, using special types of electrodes. Usually rectifiers use in professional activities, since to work with it you need to have special skills.
four. Semi -automatic is a more expensive and complex structurally unit, which has high performance and ease of operation. Semi -automatic welding units are widely used in the automotive industry, and in general for car repair. Using a semiautomatic device, you can weld such metals as aluminum, iron, steel, cast iron and stainless steel.
As a working tool in the semiautomatic device, a burner is used, through which the wire is supplying. Flus, aluminum, steel and stainless wire can be used to work with semiautomatic meters. To protect the weld from oxidation, protective gas is used, which lends itself to the welding object and displaces oxygen.
