It has been a while since this emerging technology has opened its place in industrialized countries, and in our country, the production and use of inverter welding machines has become very popular recently, and domestic manufacturers have the ability to produce them because they are good suppliers. They have proven themselves in the fields of welding cable, welding pliers, welding connector, electric cable and electronic boards inside our dear country. Due to the many advantages of this technology, it can be hoped that in the near future this technology will occupy more of the market share in the field of welding equipment.
What is an inverter welding machine?
It is a type of welding machine with modern and advanced technology, whose power supply has the ability to provide high current for welding. The input power cable of the inverter welding machine is a single-phase, two-wire type for 220 volt AC city current, which is converted into DC alternating current by a series of switches. The amount of output current and voltage of the inverter welding machine can be adjusted and during the welding process it is controlled by the output amperage of the welding machine. The inverter welding machine uses the world's latest technology and is very compact and light compared to the transformer welding machine, and also consumes much less electricity.

What is the difference between an inverter welding machine and a rectifier?
Inverter, as mentioned, is a new generation of welding tools. In fact, they are electronic elements that convert the alternating current of city electricity into direct current with high frequency. Also, the frequency and voltage level can be changed to the desired level by amplifiers. This tool is both single-phase and three-phase. Also, this device is used in minor and light cases such as welding workshops, and it will be most effective especially in the installation sector.
However, rectifiers, like transformers, are used for heavier work, with the difference that they are easy to move. Rectifiers are among the large welding machines that use two parts, inverter and transformer. Also, the amount of amperage received in inverters is 18 to 22 amperes when working. With the difference that rectifiers sometimes receive more than 25 amps and cause power fluctuations.
The function of the inverter welding machine
City electricity, which can be three-phase or single-phase, is first entered in the power source with a frequency of 50 to 60 Hz and then converted into electricity with a frequency of KHz. In this stage, the inverter unit of the device is inserted and the electricity is changed to a square wave current with DC frequency and finally, after passing through the ferrite core converters, a current is produced. Direct current is used for welding.
Some features of the inverter welding machine
• It has welding without interruption and connection (chain welding)
• Creation of a suitable welding pool and electric arc
• It does not have any sound pollution
• The possibility of controlling the current during welding compared to User's need
• High efficiency and power, light and small volume
• The possibility of welding with all kinds of tarantula, alkaline, cellulose electrodes and all kinds of wires and welding fillers
Inverter Welding Guide
If you are looking to buy an inverter welding machine, there are some points that you should pay attention to before making a purchase. Whether for domestic use or for industrial use, the welding machine must be prepared based on the abilities and according to the needs of the consumer. Welding is actually the act of joining two similar metals by melting both of them or melting another metal as Filler and adhesive are two pieces of work. In electric arc welding, in fact, the electric arc created between the electrode and the metal of the work piece causes the electrode to melt (the electrode is actually the interface between the two pieces). The way the welding machine works is actually receiving alternating current (AC) with high voltage and low current intensity, and then converting it to direct current (DC) with low voltage and instead high current intensity. Different devices have the ability to produce different current intensities. They have that the more the user needs a stronger weld and the use of the device goes towards industrial and workshop, the higher the ability to produce wing current in the device. The welding intensity we need is directly related to the thickness of the workpiece.
