Welding Inverters

Inverter welding machine - a device with the inverter power supply that converts AC line voltage to the voltage and current for welding. The main components of the inverter power source typically are:

• power rectifier, which converts the input AC voltage to a constant;
• an inverter that converts the input voltage is below a constant to a variable high frequency;
• high-frequency transformer, which lowers the voltage inverter converted;
• high-frequency output rectifier;
• smoothing choke.

Functional diagram of the power supply inverter welding machine is shown in the figure below.

Technological advantages of inverter welding machines:

• minimal spatter;
• short arc welding;
• Welding poorly welded steel;
• overheating of the minimum workpiece;
• high efficiency and performance;
• smaller dimensions compared with welding transformers;
• to obtain high quality welds do not need highly skilled welder.

Inverter welding machines are also called welding inverters.
