Welding machines, their types and accessories

Зварювальні апарати, їх типи та комплектуючі

Welding machines today are considered very popular among home craftsmen. When using it, you can perform a huge number of different operations: install a fence in a country house, attach hinges to a metal door, replace a broken water pipe, etc. In addition, using a welding machine you can not only weld individual metal parts, but also cut metal, and welding can be an indispensable assistant, since in some places it is almost impossible to cut metal with other tools. In addition, welding can be used to heat various threaded, rusted threaded connections. It is important to choose high-quality and reliable equipment and accessories for it. In particular, the oxygen rubber hose for gas welding and metal cutting GOST 9356-75 is distinguished by high quality, reliability and durability.

Now the industry produces a large number of different models of welding machines, and in order to choose the one that is most suitable, you need to at least superficially know how different modifications differ from each other.

There are several types of welding machines that are radically different from each other.

Welding transformer

The device for welding works. This welding machine design has a number of disadvantages:

  • heavy weight;
  • complexity of the work;
  • large dimensions;
  • high power consumption.

Despite all the shortcomings, this type of equipment has two undoubted advantages: it is extremely reliable in operation and relatively inexpensive to manufacture and operate.

Welding rectifier

This type of equipment is a little more convenient to operate than the previous one, and costs a little more than a transformer. The welding rectifier has a slightly lighter weight, high energy consumption, although lower than that of a transformer, and is quite reliable in operation.

Welding inverter

This type of equipment is considered the most modern equipment for manual arc welding. This machine has many benefits and advantages over other types of welding machines. The first is very low weight and dimensions. Welding is performed with constant current, which ensures very high quality of the seam. The inverter can be plugged into a power outlet without fear of network overload; these devices are quite energy efficient. In addition to the advantages of these devices, there are also disadvantages. This type of equipment is much more expensive than other types of welding machines. The devices have many electronic components in their design, which leads to relatively unreliable operation. The equipment of this is afraid of dust pollution. However, with proper care, these devices serve no less than welding transformers.
