When it comes to welding techniques, there are a few major categories to choose from. These include MIG and TIG welding, which are very fundamentally different from one another.

Both of these welding techniques will normally require their own specific welding machines, called MIG welders and TIG welders.

Both of these machines can get rather expensive when purchased together, especially when all of the welding gear that is needed for each one is added on to the tab.

However, with the help of a great multi-process welder, both hobbyist and professional welders can take advantage of a piece of equipment that provides these features all-in-one.

Many multi-process welders include, MIG welder and TIG welder welding capabilities, as well as plasma cutter functions, or some combination thereof.

Whether you are skilled in both of these techniques, or you plan to learn how throughout your welding career, you can really benefit from a one-time purchase of an all-in-one machine, instead of splurging separately on specific equipment.

Here, we will be talking about the best multi-process welders on the market that can help you with all of your welding needs.

Multi-Process Welders FAQ

What Does a Multi-Process Welder Do?

In the world of welding, there are a multitude of different techniques that can be used to produce very different results.

These techniques and categories of the craft all come with their own set of equipment and machines that will help get the job done.

For instance, when you are participating in MIG welding, you will use something called an MIG welder to complete the task at hand. The same thing goes for all other welding groups.

So, when you need to complete a welding task with a certain technique, you will need to have access to that specific machine in order to achieve the results that you want.

Well, you will need to have that specific machine in the most average circumstance, that is.

When you get more advanced in your welding hobby or career, you might find yourself wanting to explore some other techniques that you have never tried before.

Once you master the first one that you have learned, you can more easily jump to a second and a third, and keep going until you are a master welder all around.

This is where multi-process welders come in. If you find yourself in the scenario that was just described, where you are looking to learn and practice multiple welding techniques all at the same time, you can take advantage of something called a multi-process welder.

A multi-process welder is almost exactly what it sounds like: a machine that possesses several welding functions and capabilities, all in one.

When you are using a multi-process welder, you will have access to a variety of welding functions that can be alternated as you please.

With that being said, there are plenty of separate welding functions that can be present in one multi-process welder.

Let’s take a look at all of the different welding processes that are included in most multiprocess welders.

MIG Welding

MIG welding, also known as Gas Metal Arc welding, is a process that involves using gas to form an electric arc between the metal in question and the electrode on the wire of the MIG welding machine.

TIG Welding

TIG welding, or Gas Tungsten Arc welding, is  a specific welding technique that puts something called a tungsten electrode to use in attaching two metal objects together permanently.


Stick welding is an entirely separate process from MIG and TIG. The formal name for this technique is Shielded Metal Arc welding.

This process includes using electricity to melt some kind of metal material, also known as a filler.

The filler will serve to move through the joining point of two separate metal pieces, and harden there to eventually connect them.

The stick that is used to weld will melt both the point of connection and the electrode while filling the inside with the metal that was melted for this purpose.


The next welding process that is included in a lot of multiprocess welding machines is Plasma welding, or Plasma Arc welding.

This process consists of an electric arc being formed in the middle of the metal that is in question and the electrode that is being used to weld it.


Flux-Cored Arc welding, or Flux-Cored, is a process that is either semi-automatic or completely automatic from start to finish.

This welding technique requires the utilization of a flux-cored wire that is fed through a machine to ultimately join two pieces of metal together at a joining point.

The great thing about Flux-Cored welding machines is that they can be used for MIG welding as well.

The two processes are increasingly similar, which is why they are often paired together within multi-process machines.

DC Welding

DC Welding (Direct Current) is a welding technique that utilizes electrodes within a current to get the welding job done.

This type of welding can be combined with some of the other techniques, and is the opposite of AC current.

AC Welding

AC Welding is a nickname for something called Alternating Current Welding. This technique uses a certain type of electrode flowing through an alternating current to produce the output.

The main difference between AC and DC welding is the finished product. In general, DC welding tends to return the best results out of the two.

Should You Buy a Multi-Process Welder As a Beginner?

When you are a beginner in the world of welding, there are a number of factors to consider before you proceed with learning or practicing the craft.

The main concern, however, should be which welding technique and category you would like to focus on.

While this does not mean that you can only stick to one welding technique for the remainder of your career, you should always try to walk before you run.

In other words, as a beginner welder, it is best to learn just one process at a time, to avoid getting confused.

Think about learning how to ride a bike for the first time when you were younger.

You began with a tricycle, then you graduated to training wheels, before you finally got a big bike that you could ride around on freely.

Now, imagine if, as a child, you were presented with all three options at once, plus a motorcycle and a dirt bike.

If you had tried to learn all of these skills and processes at once, you would have never gotten good at just one of them.

The same concept goes for welding. You don’t want to spread your focus too thin, especially when you are first learning the craft.

However, this does not necessarily mean that you shouldn’t purchase a multi-purpose welding machine, though.

It is true that you should stick to learning and perfecting one welding technique at a time, but this shouldn’t deter you away from purchasing a multi-purpose welder as your first piece of equipment.

This is especially true if you are planning on learning each technique in the first place.

As a beginner, you can purchase a multi-purpose welder and use it as you graduate on to the next technique, after mastering the first.

There is no reason why you shouldn’t be able to have your equipment ready for you, even if you are not yet prepared to jump right in.

Overall, if you are planning on expanding your welding career in the near future, a multi-process welder is something that should be considered, even if you have never done it before.

On the other hand, if you are only focusing on one aspect of welding for one reason or another, you might just stick with the single-process machine.

Is Multi-Process Welder Good For Professionals?

Although multi-process welders are not something that beginner welders can take full advantage of right away, the same concept does not apply to professionals.

Throughout months and years of being a professional welder and perfecting your craft, it is not surprising that you might have expanded into other areas of your profession.

If you have knowledge of more than one welding technique, and you are able to find a machine that supports all of these functions, there is no reason why you shouldn’t take the leap and make the purchase.

Having access to all of these features will only benefit you in the long-run.

As an added bonus, you might be able to find a machine that features a process that you have never practiced before, in addition to the ones that you know well.

This can give you that extra push to expand your mind and your skill.

On another note, multi-process welders can be very beneficial to a professional on the business and money side of things.

Being able to offer a wide variety of welding services is critical to gaining new customers and keeping old ones.

If you are only able to offer the same service to every single customer that consults you for your welding services, they might find that they need more versatility and move on to the next person.

However, if you can be their all-in-one welder with the help of your multi-tasking machine, you will be able to bring more money to your business, instead of losing it to someone else who will!

Is It Harder To Learn To Work On Multi-Process Welders Or On MIG/TIG Welder?

When it comes to the difficulty of learning to work on different welding machines, from multi-process to MIG/TIG welders, it really depends on a lot of situational factors.

MIG/TIG welders are usually the most basic machines that will carry out the functions of each welding technique.

There are no additional modes or options to switch over, so some might argue that it would be easier to learn on one of these machines.

Many multi-process welder machines offer a lot of advanced technological features, which can make it harder for some to learn on, but it can also make it a lot easier.

It can seem confusing to learn one process on a machine that provides multiple all at once, but if you stick to practicing one technique at a time, you shouldn’t have any trouble.


As you can see, there are a multitude of options to choose from when it comes to multi-process welding machines.

You can go for the more cost-effective options that are ideal for beginners, or you can spring for the more expensive machine that will last you for a long time throughout your professional welding career.

Either way, there are a lot of questions that you will have to ask yourself when you are deciding on which multi-process welding machine will be the best for you.

Do you plan to learn all of these processes? Do you already know them? What kind of special features are you looking for that you will actually put to use?

When you consider what you will be using the machine for, how often you will be using it, and how far you would like to advance in your career with the same investment, you will be several steps closer to finding the most ideal welding machine to help you practice and perfect your craft. is the best resource for welders looking to find welding equipment recommendations, safety information, education, and DIY projects.
