Igbt Versus Mosfet Tig Welder: Which Is Better For Your Needs?
To determine which IGBT or MOSFET Welder/Cutter is right for you, you need to consider many things such as their pros and cons and their use. It is essential to know whether you are going to use it for commercial purposes, residential, industrial, or hobbyist.
IGBT inverter stands for Insulated Gate Bipolar Transistors and began to appear in the 1980s. With their high-speed switching devices, WeldClass Inverter welding machines are able to regulate voltage.

On the flip side, MOSFET is the acronym for Metal Oxide Semiconductor Field Effect Transistor. It is mostly MOSFET technology that is used in welding and plasma cutting when amplifying or switching electronic signals.
The choice of the right tool to use depends on the work at hand. Having a better understanding of how welders work and finally selecting the one who suits your needs will help you choose the one that suits you. For your convenience, we have compiled all the information you need about IGBT and Mosfet welding machines.
How Does Inverter Technology Work In Welding Machines?
Inverters are electronic systems that regulate voltage. With inverter technology, welding machines convert higher input voltages into lower output voltages. For example, a welding machine that uses 240V AC input will output 20V DV.
Bear in mind some older MOSFET technology/transistors are used in some inverter machines. As compared to MOSFETs, IGBTs have a number of notable advantages. The most significant advantage is their greater reliability and resistance to damage based on the fact that IGBTs have less exposure to power fluctuations on the mains or on generators.
Benefits of Using Inverter Welders
There are several advantages to using inverter-based products, as opposed to those that use transformers:
The biggest advantage these machines have over conventional machines is their weight and size. It is possible, for example, for an electronics inverter weighing under 5kg to have the same output capacity as a transformer with a 50kg weight.
Since inverter welding is so efficient, it is always feasible to use generator power. That is because they are able to run on much smaller generators, something that traditional transformer machines are not capable of. It is important to note that using generators comes with risks.
With inverter-based machines, it is generally possible to achieve substantially higher duty cycles. Inverters generate heat so quickly that the smaller components can be cooled much faster and easier than larger, more complicated components. Contrary to this, “transformer” welders have much bigger components and the heat is therefore stored and cooled more slowly.
A majority of traditional MMA (stick) welders are AC-only, so they can only use a limited range of electrodes. Due to the inverter-based technology, an inverter is able to rectify current into DC more easily, meaning a variety of electrodes can be welded. As a result, some inverter MMA welding machines (sticks) can also be used for DC TIG welding, which is impossible with conventional AC machines.
The PRIMEWELD TIG225X 225 Amp IGBT is an example of a quality inverter machine with an efficiency rating of 80 to 90%. As a comparison, conventional welders are only about 50% efficient.
How Does MOSFET Technology Work In Welding Machines?
In MOSFET Welders/Plasma Cutters, the MOSFET technology is used. This technology is commonly employed when amplification or switching of electronic signals is necessary. Using MOSFET technology is an option for welders and plasma cutters working under less rigorous conditions or with lower amperage equipment.
Through this technology, a welder/cutter can safely use electrical power as much as possible without overpowering the circuit gateway.
Benefits Of Using MOSFET Welders
The MOSFET device consists of three plates stacked one on top of the other, unlike an ordinary integrated power unit. With this configuration, welding operations are more stable, precise, and reliable.
Some MOSFET models can invert up to 100KHz because of the pulse width modulation technology, making it suitable for a variety of acidic and basic electrode materials. Low-carbon steel, medium-carbon steel, and alloy steel are all materials that MOSFET welding units can weld. Up until now, our MOSFET welding machines have been used mostly in the light industry, for steel repair work, and for a variety of steel structure installations at homes.
The power conversion efficiency of our MOSFET welding machine is 85%, which is 30% better than traditional welding. The welder can be protected from over-voltage, over-heat, and over-current. These features ensure the machine’s reliability and safety.
The arc-ignition function allows the welder to strike an arc easily and quickly. An electric arc welder inverter that is stable and has excellent dynamic characteristics makes welding easier and reduces weld splash.
Welders that use MOSFET inverter AC/DC are generally inexpensive. Moreover, the converters are able to convert DC power sources generated by a single conversion process or AC power sources produced by a dual conversion process. The 50 or 60 Hz AC power that enters the transformer first is converted to DC, then to AC.
Afterward, it is delivered to a mains power transformer, which converts it into low-voltage and high-frequency AC power. A DC source for welding could be converted into a filtered and rectified AC signal. Additionally, if welding is needed, it can be fed back into the inverter.
Conclusion
It does not matter which type of welder/plasma cutter you choose, igbt vs Mosfet tig welder, it should meet your welding demands perfectly without disturbing your budget. Moreover, the welding machine must be compatible with your power requirements.
