What is an Inverter Welding Machine, and How Does it Work?

Updated by

Inverters are amazing devices that have become quite necessary. Whether you talk of homes, offices, or a large truck, inverters prove to be very useful. When you’re out of power at home, it’s the inverter, which transfers the power from the battery and powers our house.

Many people confuse inverters with inverter welding machines. So if you have any doubts regarding inverter welding machines, then read this article in full. Here we’re going to discuss what inverter welding machines are, how they work, and some advantages.

What is an Inverter Welding Machine?

Now, this is quite easy to understand. As you know, an inverter uses the AC current to charge the battery and then uses the battery’s power to generate current when there’s no electricity. So, an inverter welding machine is a welding device that uses DC, converted from AC.

How Does the Inverter Welding Machine Work?

The purpose of an inverter is to regulate the voltage. In the case of an inverter welding machine, the system converts Alternate icing current into a lower voltage, i.e., 240volt Alternating current to 20volt direct current.

Inverter welding machine uses a range of electronic components to convert high voltage current into low voltage. You can think of an inverter welding machine as an advanced device that avoids the use of a single transformer to regulate voltage.

All inverter machines work in a similar fashion. And the inverter welding machine is not an exception. It can increase the frequency of the power supply from 50Hz to 20,000Hz-100,00HZ. It’s done using electronic switches, which can get the job done in a fraction of a second.

Advantages of Inverter Welding Machine

Inverter welding machines have some unique benefits or advantages that give an upper hand over the conventional welding machines. Here is why inverter welding machines are becoming popular: –

Compact and light in weight: Those old-fashioned welding machines are quite heavy, bulky, and hard to store. Also, the transformer size is quite big, which makes carrying the welding machine even harder. However, the inverter welding machine is quite compact. You can carry it wherever you want.

As these inverter welding machines have high output frequency, the transformer’s size is significantly reduced. This is what reduces the overall weight of the device and makes it more compact than ever.

Better Control: You’ll find semiconductor power devices in most inverter welding machines. It comes with an automatic transformer, which helps the welder with precise cutting or welding of the metals. However, this is not the case with conventional welding machines.

Conventional welding machines only come with a manual transformer setting. This reduces the arc stability and reduces welding accuracy. Also, with conventional welding machines, handling complex welding jobs becomes quite hard.

Better efficiency and productivity: With inverter welding machines, you can easily adjust the bead profile according to the type of job or thickness of the material. Inverter welding machines are handier and deliver a precise result.

Unlike conventional welding machines, inverter welding machines remain cool even if you use them for too long. Also, you need not to put too much filter metal. And this is what reduces the input and increases productivity.

Better Current stability and voltage: The majority of conventional welding machines consume AC power. And most of the time, the current rating and the output voltage are not constant. This delays the welding procedure as the arc takes more time to heat up and become functional.

Also, the arc is ignited and extinguished 100-120 times per second. This irregular process increases the heating time and reduces the quality of the weld. It’s the reason why welders prefer inverter welding machines.

Fortunately, inverter welding machines take care of this thing. Now, as there’s a DC current, the current flow is quite stable. There’s an anti-interference system that prevents any fluctuations in temperature and voltage. Also, the inverter welding machines heat up quickly, offering an efficient weld.

Energy Efficient device: If you have ever used those old and bulky welding machines, you would know how hard they are to carry and how much energy they use. Also, the installation is quite a complex procedure. But with inverter welding machines, the story is different.

These machines act as the best alternative for traditional welding machines. Not only is the installation easy, but Inverter welding machines consume less energy too. According to an analysis, inverter welding machines are capable of delivering a power output of up to 93%. However, with traditional welding machines, it’s somewhere around 60%.

As the transformer and reactor used in the inverter welding machine are small, it results in a compact design. And due to a small reactor size, the conductor energy consumption reduces, and hence the energy is used efficiently.

So, if you’re looking for an efficient welding option, an inverter welding machine can be great.

Better Cooling system: Old welding units heat up too soon, and it really disrupts the regular flow of work. However, with an inverter welding machine, the process is easy. You’ll find an internal cooling fan inside these units, which keeps the unit cool even after prolonged usage. This feature not only keeps the welding machine cool but adds significant life to your unit as well.

Disadvantages of Inverter Welding Machine

As every coin has two sides, the invert welding machine has some disadvantages too. These disadvantages may not be major, though. The only disadvantage is using or operating an invert welding machine requires some technical skills.

It’s composed of numerous electronic components, which makes it hard for new users to understand.

Conclusion

If you’re into the welding business, you need to know about the trend. Those days are long gone when old welding machines were prevalent. Inverter welding machines are in power these days because of their reliable, compact, and highly efficient nature.

You can go through the advantages and learn why inverter welding machines are better than their traditional counterparts. If you find the above insights useful, make sure to share them with others who may want to learn. We’ll keep posting similar content. So, keep coming for more.
