I remember when I first started welding. I had just graduated from high school and was looking for a good, entry-level job that would pay me well. One of the most popular jobs in my area at the time seemed to be welding, so I went and got certified right away. But as soon as I started working with an inverter welder, something didn't seem right to me - it was too easy. Admittedly, this blog is about the advantages and disadvantages of inverter welders (and whether they're easier than traditional welders), but even if you don't want to buy one yourself - consider reading on because there are some great points made here.

So, what are the advantages of an inverter welder? Inverters welders are portable and lightweight machines that use a high frequency current to create an arc between two electrodes. This arc melts the metal and joins it together. Compared to traditional welders, which use alternating current (AC), inverters welders are much lighter and more portable. They're a great beginner welder for someone who doesn't want to lug around something that will be very heavy.

Let's talk about the advantages of inverter welders.

Inverter Welding Machine Advantages

Anyway, after doing a bit more research, it turns out that there are some pretty clear advantages of inverter welders when compared to traditional welders. Here are just a few:

  • Small Size, Light Weight, Saving Manufacturing Materials, Portable and Easy To Move

This is a special type of sheet metal that is easy to move and will not weigh as much as traditional metals. It also saves materials because it's small and lightweight. A welder can use this to make things like trucks, trains, and other vehicles that need sheet metal.

Moreover, inverter welders are easy to move, using fewer materials to make. They also have a high frequency, so it is good for the transformer. Using an inverter welder will be even better because the transformer has a magnetic flux density and the current frequency.

Inverter welding machines have a high frequency, making the transformer smaller and lighter. The more power, the smaller it will be. With a higher frequency, the reactor is also small and light.

  • Flexible Control

An inverter welder is a device that can precisely control the size of the current in the microsecond range. Which means it can improve your precision welding and cutting. Traditional welding machines only adjust their current by manual adjustments to the transformer, making arc stability poor and unable to control the welding process accurately.

  • Energy Saving And High Efficiency

Transformers and reactors in an inverter welder make the machine smaller and lighter. This makes it easier to move around. The power losses in this welder are less than for a regular welder (mainly magnetic core loss and conductor energy consumption). This means that you can get more power from your machine- up to 82% ~ 93%. A traditional welder only gives you 40% to 60%, which wastes many power resources.

  • Output Voltage And Current Stability

Inverter welders can help avoid problems with other machines from interfering. It is less likely for voltage to change and the temperature of the welder to change while you are working. An inverter welder will usually use AC power because it often changes direction, so the arc would go out and come back 100-120 times a second. This is not good because it makes the workpiece heat up too much while welding and reduces how strong your weld can be.

This welding machine is often used for portable applications because it is lightweight and more compact than traditional welding machines. While there are many advantages to using an inverter welder, there are also a few disadvantages.

Here are some of the disadvantages of an inverter welder:

Inverter Welding Machine Disadvantages

Inverter Welding machines are not perfect. They have some problems, but they are better than traditional welding machines.

  • One problem is that cheap inverters are not reliable.
  • Another problem is that inverters cost more to repair after the warranty finishes.
  • This machine does not last as long as a traditional welding machine.

Let's discuss it in more depth.

  • Cheap Unreliable Inverters

Inverters welder are a great tool. If you want to get an inverter welder, you must spend more than $200 on one. And if you have a welder, make sure they know that the cheapest ones cost less than $80 and are poorly made.

If you are lucky, you can use an inverter for a few months before it breaks. The cost of fixing an inexpensive one is about half the value of the machine. When you buy an inverter, spend more money to get one that will last for several years.

  • Higher Repair Costs

Some traditional AC welders have a design that has been the same for over 50 years, and they are cheaper to repair. Inverters are more complex and contain software and electronics.

Once your warranty is up, you will have to pay more to fix an inverter. One way to avoid the high cost is to extend your warranty now. Manufacturers usually let you buy a longer warranty when you first buy the house.

  • Less Durable than AC Welders

Inverters are lighter and smaller than AC welders. But they are not as strong. The inverter is easier to take with you when you work on a job site. But if it falls or is in a dirty place, it might break more easily than an AC welder.

If your inverter becomes dust-covered, the electronics inside can get messed up and might not work anymore. In comparison, many AC welders can be dropped and still work. The inverter is not as durable under these conditions, so you need to take good care of it.

In more detail, inverters are not as durable because they have many moving parts and circuit boards, making them more sensitive to falling and drops.

Most of the time, you'll be using your inverter in a clean place like an office or home. They can become dirty but usually won't get too smudged up.

AC welders are more durable because they don't have any moving parts or circuit boards. They are more likely to work after being dropped or smacked around.

Most AC welders will be used in a factory or construction site. These places are not as clean as an office, and there is a higher chance of getting dirty.

That's why inverters are not as durable.

Is It Easier To Weld With An Inverter Welder?

It is easier to weld with an inverter welder. It heats up quickly, but it can cool off more easily. And the current can be turned into DC so that they can weld many different kinds of electrodes.

Inverter machines are different than regular machines. When it gets hot, it is easy to cool down. It can also change what the current does to weld a lot of different things. It is a newer machine, so that it might be more expensive, but the welds look nicer.

How Reliable Are Inverter Welders?

Today, inverter welders are a popular choice for welding projects. They offer great flexibility because they can be used with various electrodes and materials. Inverters are also more efficient than transformer welders, which mean you save on energy costs.

Despite these benefits, there are some drawbacks to using inverter welders. They are not as reliable as transformer machines. Certain manufacturing and design changes help them work better, but they are not the best choice for most jobs. For some jobs, weld quality costs more than what you save on electricity prices.

However, inverter welders can be a good choice for a small project if you have limited space and need to do your work quickly.

The first inverter welder was introduced in the market over a decade ago. The technology has been perfected and made more affordable to customers, who have benefited from it immensely.


 The advantages of an inverter welder are that it provides more power than a traditional arc or MIG. If you need to weld thicker metals, the increased amperage and voltage will help get your job done faster while producing less spatter. But if you don't have very much money, there is no reason not to buy a standard welding machine for jobs where its max output can be utilized without issue. You might want to consider investing in some consumables like wire brushes and flux-cored wire for this type of work because they are cheaper than solid wires, which last longer when used with thick materials.
