If you are in the market for a welder, you may be wondering whether an inverter or transformer welder is right for you. Both types of welders have their pros and cons, so it can be difficult to decide which one is best for your needs. In this blog post, we will compare and contrast inverter vs transformer welders to help you make the best decision for your business.
Transformer Welders
Transformer welders have been around for much longer than inverter welders. Transformer welders were the only type of welder available until the early 1990s.
Transformer welders are known for their durability and reliability. They are also typically more powerful than inverter welders, making them a good choice for heavy-duty welding applications.
However, transformer welders are also heavier and more expensive than inverter welders.
What is a Transformer Welder?
A transformer welder is a type of welding machine that uses an electrical current to weld two pieces of metal together. The current is passed through a transformer, which increases the voltage and creates an arc between the two pieces of metal. Transformer welders are more expensive than other types of welding machines, but they offer several advantages.
Transformer welders are more powerful than other types of welding machines, so they can handle thicker metals. And because they don’t have any moving parts, they’re very durable and require little maintenance.
Quick History of the Transformer
The first transformer welder was built in the early 1900s. It used a large transformer to convert alternating current (AC) into direct current (DC). This made it possible to weld metals together with much less heat than was possible with AC welding.
The first transformer welders were very large and expensive, so they were mostly used in factories and shipyards. In the 1950s, smaller transformers were developed that could be used by hobbyists and small businesses.
Today, transformer welders are still widely used, but they have been largely replaced by inverter welders for many applications. Inverter welders are smaller, lighter, more efficient, and less expensive than transformer welders.
How Does a Transformer Welder Work?
A transformer welder uses an alternating current (AC) to create a magnetic field in the primary winding of the transformer. This magnetic field is then used to generate a current in the secondary winding of the transformer, which is used to power the welding arc.
The main advantage of a transformer welder is that it is very efficient at converting AC into DC, which means that it can produce a lot of power with relatively little input.
However, the downside of this efficiency is that transformer welders tend to be quite large and heavy, which can make them difficult to move around. In addition, they are also generally more expensive than inverter welders.
Advantages & Disadvantages of Transformer Welders
Transformer welders have many advantages, the most significant being that they are very durable. However, there are some disadvantages to using a transformer welder as well.
One of the biggest disadvantages is that transformer welders can be quite loud. Additionally, they often require more maintenance than inverter welders and can be more difficult to operate.
Pros:
- They are more consistent in their welding results.
- They can weld at a much higher voltage, which leads to a faster weld.
- They are better at welding thicker materials.
Cons:
- Transformer welders are significantly heavier and more difficult to transport.
- These are generally more expensive than inverter welders.
- Transformer welders tend to be less energy-efficient than inverter welders.
When to Use a Transformer Welder
A transformer welder is ideal for projects that require heavy-duty weldings, such as shipbuilding or pipeline construction. That’s because transformer welders can handle much more amperage than inverter welders. If you’re working on a project that requires high amperage, a transformer welder is a way to go.

Inverter vs. Transformer Welders – Which is better?
The debate between Inverter and Transformer welding machines has been around for a while. Each type of machine has its own set of pros and cons that make it better or worse for specific types of projects. We’ll break down the key differences between Inverter and Transformer welders so you can decide which one is the best fit for your needs.
Performance
Inverter welders are smaller and more portable than transformer welders. They also tend to be they offer superior performance. Inverters are better for welding aluminum, stainless steel, and other thin materials. Transformer welders are better for welding thicker materials like steel.
Energy Efficiency
Inverter welders are more energy-efficient than transformer welders. Inverter welders use less power to produce the same amount of welding output, which means they’re less likely to overheat and damage your equipment.
Output Level
The first thing you need to consider when choosing between an inverter or transformer welder is the output level. Inverters typically have a lower output level than transformers. This means that they’re not as powerful and can’t weld as thick of material. If you’re planning on doing any heavy-duty welding, then a transformer welder is going to be your best bet.
However, if you’re only planning on doing light-duty welding, then an inverter welder will be just fine. It’ll probably be better since it’s lighter and more portable.
Reliability & Life Expectancy
The transformer welder is a more reliable machine. It is less likely to overheat and break down. When it does eventually break down, it is easier and cheaper to repair. Inverter welders, on the other hand, are more delicate. They are prone to overheating and breaking down. When they do break down, they are often not worth repairing and you will have to buy a new one.
The average life expectancy of a transformer welder is about 20 years. Inverter welders have an average life expectancy of about five years.
This means that you will get more use out of a transformer welder in the long run. If you want a machine that will last longer and be more reliable, go with a transformer welder. If you are more concerned with the initial cost, go with an inverter welder. In the end, it is up to you to decide which machine is better for you.
Weight and Portability
When it comes to weight and portability, inverter welders tend to be lighter and more portable than transformer welders. Inverter welders are a good choice for people who need to move their welder around often or those who don’t have a lot of space to store a welder.
Applications and Preferable Environment
Inverter welders are smaller, more lightweight, and more portable than transformer welders. They are also less expensive. Inverter welders are better for light-duty weldings, such as automotive repair or home projects.
Transformer welders are better for heavy-duty weldings, such as construction or manufacturing.
Required Experience
Both inverter and transformer welders have their advantages and disadvantages. To decide which one is better for you, you need to consider your experience level and the types of projects you’ll be working on.
Price
The cost of an inverter welder is usually cheaper than the transformer model. Inverters are smaller in size, and they use less material to operate.
If you’re looking for a welder that’s both affordable and durable, then an inverter welder is the way to go. You’ll get more bang for your buck with an inverter welder.
What’s your budget? If you’re working with a limited budget, then an inverter welder is the best option for you.
Known Problems
Inverter welders are not without their problems, however. There are a few known issues that can occur when using this type of welder. One of the most common problems is arc blow.
Arc blow occurs when the welding arc is deflected by a strong magnetic field. This can cause the arc to become unstable and can eventually lead to weld defects.
Another problem that can occur is power fluctuations. Power fluctuations can cause the welding arc to become unstable and can also lead to weld defects. In addition, power fluctuations can damage sensitive electronic components within the welder.
What is IGBT Technology?
Inverter welders use IGBTs to control the flow of electricity, making them more efficient than traditional transformer welders.
The main advantage of IGBT technology is that it makes inverter welders much lighter and more portable than transformer welders. Inverter welders are also able to create higher-quality welds, thanks to their ability to better regulate the flow of electricity.
Can I use my arc welding inverter to charge my 12V car battery?
The quick answer is no. Inverters are not designed to charge batteries. If you tried to use your arc welder inverter to charge a battery, you could damage the inverter or even start a fire.
What will happen if I will try to hold the positive and negative ports of an inverter welding machine while it’s running?
You’ll probably get a nasty shock. Inverter welding machines work by converting AC into DC. This process is known as rectification, and it’s what makes inverter welders so much more efficient than traditional transformer welders.
However, it also means that the machine produces a lot of dangerous electrical waste – which is why you should never touch the positive and negative ports while the machine is running.
You should always make sure that the machine is properly grounded before using it. Otherwise, you could end up electrocuting yourself!
Can you TIG weld with an inverter welder?
Inverter welders are smaller, more portable, and more affordable than transformer welders. They are also easier to use, making them a good choice for beginners. However, inverter welders are not as powerful as transformer welders and cannot be used to TIG weld.
Which is better between a three-phase welding machine and a single-phase inverter welding machine?
The answer to this question is not as simple as it might seem at first. To decide which type of machine is better for you, there are a few factors you need to consider.
- The first factor you need to consider is the power source. Three-phase welding machines require a three-phase power source, while inverter welding machines can run off of either single or three-phase power. If you have access to a three-phase power source, then a three-phase welding machine will be more efficient and will likely produce higher-quality welds. However, if you only have access to a single-phase power source, then an inverter welding machine is your only option.
- The second factor you need to consider is the type of materials you’ll be welding. Inverter welding machines are better suited for thinner materials, while three-phase welding machines are better for thicker materials. If you’re not sure what thicknesses you’ll be working with, it’s best to err on the side of a three-phase machine.
- The third and final factor to consider is cost. Three-phase welding machines are typically more expensive than inverter machines. If cost is a major consideration for you, then an inverter machine might be the better option.
Conclusion
So there you have it: Inverter vs Transformer Welder – which one is better for you? If you’re looking for a more efficient welding machine, then an inverter welder is the way to go. However, if you’re more concerned about safety, then a transformer welder is probably a better option.
Whichever one you choose, just make sure that you always follow the manufacturer’s instructions carefully. And never, ever touch the positive and negative ports while the machine is running!
