What Is Multi-Process Welding?

Multi-process welding as the name implies is the way or activity in which welders carry out some different welding activities and can apply different welding techniques. Now, this activity has been made to be carried out using just one welding machine.

The welding machine that performs all these tasks is called a multi-process welder. This machine makes it easy for a welder to take on different activities; such as fabrication or construction activities in the workshop or on the site, using one device with one power source.

The Advantages

  • It is relatively cheaper to get one machine that does many welding activities than to get individual welders.
  • Using this saves time and allows for faster completion of jobs. It will enable gives room for more welding activities to be done using just that welder.
  • It is convenient to use and can be easily adjusted for your various needs and is portable.

The Disadvantages

  • The only cons a multi-purpose welder has is its weight. Some machines weigh a lot. If it is to be used in the industry, then it is no issue.
  • But imagine having a say; a 40-pound machine that requires you to move it around would not be easy at all.
  • Taking into consideration the rate at which you will be moving the machine around before buying can enable you to choose the good quality multi-purpose welder that eliminates this problem of weight. This is because there are lightweight welders available as well.

How to Choose the Multi-Process Welder?

In buying a multi-process welder, the operator will certainly want to choose the best one he can find. Several factors have to be considered before making any decision on what multi-process welding machine to buy.

These factors below will guide you depending on what you want to do with the machine, to buy the one that suits your needs the best. So, check out all factors below before visit welding shops to find your desire product.

Performance of The Welder

Before getting a multi-process welding machine, ensure it has a high-performance rating. This allows for more productive work in a reasonable time. Check reviews and ratings of the device to give you a clue as to how the machine is.

Positive reviews = high performance most of the time. Do not buy the machine blindly when you have access to the feedback from other people that have tested it.

Power Supply – AC & DC Capability

Power supply plays an important role when purchasing a machine as it affects many things while using the machine. Some multi-process welding machines require a type of constant current; either AC or DC.

If you buy a multi-process welder that supplies the two, this will give you the flexibility to use it on several welding activities.

For example, the MIG and stick welding requires the use of a DC current most times. Any welder that has both AC and DC capability is the best quality multi-purpose welder machine to consider getting.

Your Budget

Knowing how much you have budgeted for the machine, streamline to the reason you want the machine, to get a good machine no matter your budget. Different multi-process welders come with different features that also come at different prices.

The weight of The Machine

Depending on the reason for getting the machine, you should also consider the weight. If you are going to leave the machine in one location for a long duration of time; you can afford to get the heavyweight machine.

In the instance that you are getting it for small projects which require you to go from place to place regularly; it is advisable to get a more portable machine to make it easy for you while moving.

If you do insist on getting the heavier weighted machine; you will need a welding/plasma cutter cart to enable you to move the machine.


No operator would want to spend money on getting a multi-process machine that would pack up after just a few times of use. Getting a durable machine is essential and gives value for your money spent on acquiring the machine.

Don’t forget to pay attention to the warranty of the machine you want to buy; in fact, I should have started with the fact that you have to get a machine that comes with a warranty.

Are Multi-Process Welders Any Good?

It depends on what you want out of the welder. Most multi-process welders lean towards one particular style. While a welder might advertise it can perform all 3 methods, it might be better at TIG or MIG welding, as an example.

The watchword, when buying a multi-process welder, is quality. Getting the best welder for your dollars is crucial if you want a machine that will last for years and years, delivering the best consistent performance.

You could also levy the accusation that they are “Jack of all trades” machines, but they are cost-effective because they keep your expenditure low by allowing you to be flexible without adding to your costs.

They also speed up your work rate because you only need to configure one machine rather than drag another from the truck when you switch welding styles.

On a professional level, you are more likely to purchase a welder that caters to a specific style, but that’s because the standards are so much higher in the commercial and industrial sectors.PROS:

  • Cost-effective.
  • Saves time on set-up.
  • You can swap techniques at will.
  • Compact and lightweight.
  • Comes with all the equipment.
  • Cheaper set-up costs.
  • Portable.
  • Versatile.


  • Putting all your eggs in one basket.
  • Doesn’t specialize in any method.
  • Varying degrees of quality.
  • Too many cheap models that break.

The Different Types of Welding

The primary types of welding found in industry and by home hobbyists are generally known as Mig welding, Arc welding, Gas welding and Tig welding.

GTAW or Tungsten Inert Gas Welding

TIG welding resembles oxy acetylene gas welding and requires much more know-how from the operator. Useful for undertaking top quality work whenever a exceptional quality of finish is necessary without employing too much cleanup by sanding or grinding .

Arc Welding or SMAW Welding

Often known as stick or arc welding. Arc welding is easily the most standard of all welding types, is straightforward to perfect in the home for a variety of welding circumstances. Stick welding can be used for manufacturing, construction and repairs, very much well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are usually more suited to the MIG welding types.

Gas or Oxy Acetylene Welding And Cutting

Not employed as extensively for basic welding of mild steel. Is made up of mixing oxygen and acetylene gas to create a flame able to melting steel materials. It is primarily utilized nowadays for servicing work and gas metal cutting. Additionally it is common for brazing softer metals, for example copper and bronze.

It may also be used for welding fragile aluminum components for example refrigeration plumbing. Probably the most accessible of thermal cutting gear is oxy-acetylene gas cutting and plasma cutting equipment. Additional techniques range from the use of a thermal cutting electrode to be used with the arc welder machine

GMAW or Gas Metal Arc Welding

Additionally called MIG welding this welding type is easily the most commonly used and possibly the most effortlessly mastered variety of welding for business and residential use. The GMAW process would work for fusing mild steel, stainless-steel in addition to aluminium.

Types of welding processes

In order to have an improved understanding of multi-process welders, it is important to know the different types of welding processes. They are three, which are:

TIG welding

Also known as Tungsten Inert Gas welding, this uses an electric torch alongside a tungsten electrode, which then gives the welding arc some power. You then add a filler rod, and this will weld the metals.

As a shield gas, you use an inert gas, usually argon – this will also act as a coolant for the weld puddle and protect it from contamination or oxidation. The method does not produce as much heat as MIG welding, and this makes it great for lighter metals and their alloys.

MIG welding

This involves the use of a MIG welding gun and spool wire when welding the metal. It can be used for a variety of surfaces regardless of thickness, such as stainless steel, nickel, or even aluminum (in some cases), and is among the easiest welding methods to learn.

However, it cannot be used for all metals because of the very high temperatures it produces, which can destroy lighter metals and alloys. In addition, the results must be free of corrosion, because the process is not weather resistant.

Stick welding

This involves the combination of the work piece and an electrode, and they are subjected to high temperatures until they melt, then the mixture is welded. In order to prevent contamination of the mixture, you use flux core to coat the mixture.

The process is the most heavy-duty of the three, and it is usually used when you are welding very heavy or thick metals. It also generates a lot of heat – even more than MIG welding. The process is also quite challenging to learn, because you will need to control the different elements of the process.

Benefits of a multi-purpose welder

The truth is, purchasing a multi-purpose welder is not the easiest task – in many cases, it can end up being more challenging than buying a welder that specifically caters to a specific welding method. But, like any other purchase, it is important to consider a few factors before making your purchase.

Before doing so though, it is great to start from knowing what makes a multipurpose welder unique from other welders, and the advantages they offer you as well.

Gives versatility

This is the reason why these welders exist – to offer you a wide array of options you can use during the welding process, without forcing you to look for equipment catering to that specific task. This is due to the fact that these welders can handle several combinations, such as flux core, MIG, stick, and TIG welding, all in one machine.

Extra convenience

These welders should make it much easier for you to accomplish a variety of projects in your workshop or construction site. This is all because of their ability to change according to the present needs, so you can adjust their use according to your needs. You will also not need to change the power sources when you are working of different tasks.

Due to this, both professional and amateur welders will appreciate the convenience these machines bring to the job.

Space saving

The main problem of having multiple machines that all look similar and some functioning in similar ways is that they can occupy a lot of space in your workshop or storage, and it is tiresome to keep arranging them all the time. A multi-process welder will help to save this space, because one welder fits a multitude of needs. It will also help during transportation, since you will not need to carry a host of welders in your car.


These multipurpose welders can prove to be more costly compared to the specialized welder types in some cases, but this is ultimately negligible to buying a ton of different welders to cover a specific task. In the long term, a multi-process welder will save you money, as they perform a variety of tasks at a go using the same equipment.

Things to Keep in Mind While Buying a Multi-Process Welder

Defining your use cases is the first step to narrowing down the options and making an informed decision in a sea of multi-process welders.

  1. Do you need more power or amperage for the projects you are working on now or in the future? It is essential to consider such scenarios.
  2. You probably have a budget in mind. But do not forget to factor in the cost of additional accessories and operation as well.
  3. Always be sure to check the quality of your product. Read customer’s reviews.
  4. Do not compromise quality for aesthetics, a lighter welder, or a lower price. This will only cost you in the long run.
  5. All things considered, make an informed financial decision. Welders are expensive, but when you pick the right one, it can be a lifetime investment with returns that keep on coming!
  6. Don’t rush the decision. This is a choice that will help change the course of your work. So take your time, do your research, and talk to people before taking the plunge.


What is the strongest weld?

The strongest weld is the one done well. The reason why different techniques exist depends on the type of material and other factors.

What is the hardest metal to weld?

Aluminum is considered the most difficult metal to weld because, due to its physical and chemical properties, it requires more knowledge and experience.

Can I weld aluminum without gas?

Without shielding gas, the molten aluminum would react with the oxygen present in the air, and the result would be a porous weld full of oxides and, therefore, very fragile.

What is the easiest metal to weld?

Steel is basically the easiest metal to weld, using any technique.

Can you MIG weld stainless steel without gas?

The question is incorrect. The MIG (Metal Inert Gas) welding technique involves the use of gas. However, it is possible to stick weld the stainless steel obtaining excellent results.

Is it safe to weld bolts?

No. The metal of the bolts is heat-treated to make it stronger and more resistant. The heat of the weld can adversely alter these properties, and therefore it is always better not to weld nuts or bolts.

Conclusion and Best Offer

Multi process welders are an incredible addition to any metalworker’s arsenal.

Hopefully, this comprehensive look has set you on the right track to make an informed decision about buying a new device.

The highlight product on this list is definitely the Esab Rebel EMP 205ic Multi-Process Welder, based on functionality, quality, versatility, portability, and power.
