IGBT (Insulated Gate Bipolar Transistor) inverter technology is a type of advanced electronics used in modern welders—such as MMA, TIG, or MIG inverter welders —to make them more efficient, lightweight, and precise than traditional transformer welders.
Here's a simple explanation:
How it works
An IGBT welder converts alternating current (AC) from the electrical grid into direct current (DC) using an electronic circuit that "inverts" the frequency (from 60 Hz to thousands of Hz).
This allows the team to use much smaller and lighter transformers , reducing the size and weight of the welder.
Main advantages
-
Energy saving:
It uses less electricity than a traditional welder to achieve the same result. -
Smooth ignition and stable arc:
The current is electronically regulated, allowing for a more stable and uniform arc , making the job easier even for beginners. -
Smart protection:
IGBT transistors better control the flow of electricity, reducing the risk of overload, overheating, or short circuits. -
Portability:
Thanks to the inverter design, IGBT welders typically weigh between 3 and 6 kg , compared to over 20 kg for older models. -
Longer lifespan:
The components work more efficiently and with less waste heat, extending the durability of the equipment.
In summary, IGBT inverter technology is the modern heart of portable welders: it combines power and precision in a compact body, offering a cleaner arc, lower power consumption, and a more controlled welding experience.
