What Is An Inverter Welder – A Go Through Guide

The World of welding introduced a new type of welder, “inverter welder,” several years back. They’re fast, innovative, and holds a list of advantages when compared to other welders. 

 On a technical level, an inverter welder uses refined silicon-based technology. Further, the inverter welding market went through a rough patch in the early days because of teething problems. 

 However, when experts discovered the real cause behind the problems. Since then, inverter technology became dependable, less expensive, and highly efficient. 

 More so, its small size, compact design, and easy to carry features are some of the prime benefits. Also, you can carry it like a briefcase whenever you want to hunt metals. 

How Does An Inverter Welder Works

An inverter is an electronic device that regulates the voltage according to your needs. As well, an inverter welding machine transforms AC power into a usable output voltage. For example, from 110V AC supply to 10V DC output.  

 Further, inverter-based devices consist of various electronic components that coverts the power. On the other hand, transformer welders come with an integrated transformer that converts the voltage. 

 Moreover, an inverter’s working methodology is that it increases the frequency of the power supply from 40 Hz up to 30,000 – 100,000. It uses electronic switches to turn on and off the supply within one-millionth of a second. Also, it’s one of the reasons inverter welders are small and portable.

What are the advantages of using Inverter Welders?

Inverter welding machines offer a variety of advantages when compared to other welding processes. We’ve listed some of the significant benefits below; read them out now!


A top-notch inverter machine performs much better than many conventional welders. The statements come true when you use MMA stick welding because it’s too much easy to operate, and you don’t have to worry about the arc.

Further, the ability of these machines features higher open-circuit voltages. Moreover, you’ll find it close to impossible if you use a traditional stick welder to weld thin metals.

But, an inverter welder consists of infinite multiple amperage adjustment and a stable arc. It allows you to lower the output amperage to weld up to 1.6 mm sheet metal with significant control.

Direct Current Output (DC):

You can weld all types of electrodes with an inverter welder because it works on direct current. And due to regulated current, these welders perform better and offer a large variety of welding materials.

Aside from that, its ergonomic design and lightweight enable you to use it on any commercial or construction site.

Duty Cycle:

As you know that, the duty cycle is the average number of minutes you can weld in 10 minutes. For example, if a machine offers a 40 percent duty cycle, then it means you can weld 4 minutes regularly. And you’ve to give 6 minutes rest to the device, to start work again.

When it comes to inverter-based machines, their transformer is small to achieve a higher duty cycle. But how? Because the components are smaller, if they heat up quickly, they cool down faster.

While standard transformers’ components are large, they need a lot of time to return to working order.

Energy Saving And Efficiency:

While the small components impact the size and weight of the inverter, the magnetic loss and conductors’ energy consumption are also low.

Further, an excellent gadget can uplift adequate output power to 82% to 92%. While, the average welder’s good power is only 40% to 60%, and it wastes a lot of power resources.

Pricey But Potable:

While their price is much higher than standard MIG, TIG, and MAG welders, but their low weight makes them easy to transport. 

A Variety Of Functions:

Inverter welder electronics can bear additional features easily (such as MIG or TIG mode). Also, they make existing jobs more controllable and stable.
