What is inverter welding

Transformer machines are long gone. Now they are replaced by welding inverters. They allow you to quickly and efficiently weld metal parts and structures. Usually inverters are used as power sources welding when carrying out arc welding by melting. The use of this type of apparatus is known that, due to the constant characteristic of the welding current and its stability, achieves excellent seam quality that guarantees durable and reliable metal connection.

What is inverter welding? In fact, this process using the schema of the system or of a device that generates AC voltage when connecting the DC power source. To put it more specifically, such type of welding is the process of working through the inverter, traditionally, is a manual arc welding.

The General scheme of such welding consists of a network filter network rectifier, frequency Converter, high frequency transformer, power rectifier and control system.

Of course, for the implementation of the weld metal per unit of a little, we need more accessories, mask, headbands and, of course, the electrodes. Without them, no job is impossible. Electrodes for inverter welding are of three types – carbon, alloyed and high alloy.

The main advantages of the inverter welding machine are:

- easy and rapid ignition, stable arc, good elasticity;
- high quality welding seam;
- energy saving;
-high efficiency;
- fluctuations in the supply voltage do not affect the welding parameters;
the lightness and mobility.

Of course, inverter welding has disadvantages: used for machines, like any other electronics do not like water, dust and frost. Therefore, to keep inverter welding in a dry and sufficiently warm room. It is also important to regularly open the case and blow out parts with compressed air.
