Best Multi Process Welders: Are you planning to take up some metalworking projects or are you interested in making a profession out of metalworking? Whatever may your interests be, you have to buy a welder for yourself if you want to be a metalworker. Without a welder, it would be impossible to carry out even the simplest of the metalworking projects, whether that be DIY or professional. However, when it comes to buying a welder, many fail to arrive at a decision about what type of welder they should buy. The choice of the type of welder depends on the type of metalworking that you are planning to do. Thick, rusty metals need a different kind of welding process (stick) while finer metals pieces would need a different process (TIG). So, depending on the type of projects that you want to complete, the choice of the welder – MIG/TIG/Stick must be done. But what if you want to work on a variety of projects that will require two or more types of welding processes? Do you buy a separate welder for all the different types of welding that you need to do? Well, you could do that, but it would be quite expensive, not to mention that you will have two or more welders lying about in your home or workshop. An ideal solution, however, would be if you could have a welder that would be able to carry out all the different types of welding processes. And that is exactly what a multi-process welder is for.
What is a Multi-Process Welder?
As the name suggests, a multi-process welder can support multiple welding processes. This usually includes a combination of TIG and MIG, MIG and Stick, Stick and TIG and sometimes, TIG, MIG and Stick together. Some models also come equipped with the facilities of a plasma cutter, though in many a case, that may not be quite up to the mark. The upside to having a multi-process welder is that you can carry out projects involving two or more types of welding without having to buy a separate welder for each process. Multi-process welders do cost more than single process ones, but you are sure to save a lot of money if you intend to be versatile at the type of metalworking that you do. In fact, multi-process welders are the all-in-one solution for welding purposes and you can use them for a wide range of tasks including maintenance and repairs, small-scale industrial work, etc. With a multi-process welder in your arsenal, you can carry out all types of welding works with utmost ease and convenience.
Common Multi-Process Combinations
Multi-function welders offer a different combination of welding processes to help metalworkers in a variety of projects and jobs. However, of the various combinations that you can get in models from various popular brands, the following are the most common:
TIG/MIG/Stick: This is one of the most popular combinations that you can find in multi-process welders. And there is enough reason for that. This combination of welding types will allow welders to work on a wide range of metal projects, whether that be DIY or professional. As such, this combination is favored by most welders.
TIG/MIG/Cutter: This is another popular combination found in many multi-function welders available in the market. The Stick welding feature is replaced by the cutter so that along with the welding, you can also perform some basic constructional work.
TIG/Stick/Plasma: – For welders willing to work predominantly on exotic materials, this is the perfect combination.
How Does a Multi-Process Welder Work?
The working of a multi-process welder isn’t much different than the individual/dedicated welders of the different types involved. Suppose, you buy a multi-process welder that has a MIG/TIG/Stick combination; each process will work exactly as they would in a dedicated welder. All that you would need to do is switch to the process that you need to use and the rest of the working would be similar to a dedicated welder. However, you must remember to make the changes that the new process would need, like plugging in the right components and unplugging those that wouldn’t be needed.
Advantages and Disadvantages of Multi-Process Welders
Multi-process welders are really powerful tools that use the latest technology to ensure that all types of welding tasks can be carried out with ease. However, they are ideal or useful only for people who tend to work on metal projects quite often or those who want to be associated with metal working professionally. Here are some of the advantages that a multi-process welder can offer to a metalworking enthusiast or professional.
Versatility: The first and most important advantage of owning multi-process welding is the versatility that it offers. Before taking up a project or task, you wouldn’t have to think whether you would be able to complete it or not. Irrespective of the welding process that the project may require, you would be able to do it without any worry at all. Being equipped with Stick, MIG, TIG and sometimes, even plasma cutting facilities, multi-process welders are what any DIY enthusiast or professional metalworker would look for in a welder.
Convenience: Since a single welder will be able to perform all types of welding processes, you wouldn’t need to switch between different machines when you require different types of welding in a single project. This will be greatly convenient to you and you will be able to work on all types of projects with ease. Not only that, the best multi-process welder will come with easy to use controls and settings that are loved by all beginners and professionals.
Space-Saving: Having a multi-process welder means that you can easily do away with the other welders that you may have. This will surely help you save some space that was earlier occupied by the bulky welding machines that you had. This is great for DIY enthusiasts as well as professionals who may not have enough storage space in their shed/garage/workshop. You can also easily port single equipment and be relieved of having to port two or three different welders when you may need to carry out the welding at different places around the house.
Price: Multi-process welders are, in general, more expensive than the single process welders. However, that is compensated by the fact that you have to pay for only welder and not two or three of them. It must, however, be remembered that paying the extra price is worthwhile only if you would use all the different types of welding processes for your work.
Along with the advantages that one can get with a multi-function welder, the disadvantages must also be taken into account before a purchase is made. Though there are no major downsides of a multi-function welder, here are a few points that need consideration
Weight: Multi-function welders are usually on the heavier side as compared to other types of welders. In fact, some welders weight more than 85 lbs. which is quite heavy. This may not seem to be a problem to those who work at industrial sites or at their own workshops at a professional level. However, for DIYers, the weight might pose a problem as the welder may have to be carried from one place to another. Also, in workshops and industrial sites, the welder may need repositioning to be able to work at different desired angles. Heavier models may require some extra effort.
Efficiency: Multi-process welders are capable of performing different types of welding. But it has been often seen that many multi-function units are good at one welding process while they offer average performance with the other welding processes. This means that you may have to compromise with the quality of some welds. However, the issue is often quite negligible and can be overlooked, unless you are looking for extremely fine finishing.
Settings: To be able to switch between two welding processes, you will have to set up the welder according. You may have to change the gas, plug-in some items that are necessary for the process and unplug those that aren’t necessary. This setup process will need some time, every time you have to switch between welding processes as the process isn’t automatic.
Power Source: A common problem that you may face with certain multi-function units is that they do not come equipped AC TIG welding. This may pose to be a problem in case of certain units if a DC power source isn’t available or suitable.
Things to Look for in a Multi-Process Welder
Investing in a welder without understanding which welder would be the best suited for your purpose is surely a disaster in making. You would surely want to avoid doing anything that may result in monetary loss or hamper the projects that you want to work on. The market may be flooded with multi-process welder models, but you have to decide which one will be the best for you. The following factors will help you find the best pick for your work:
Welding Process Combination:
Not all multi-function welders have the same combination of welding processes. And this will go a long way in determining which model to go for. Choosing a welder that doesn’t have the welding combination that you need will be nothing but a waste of money. Commonly, beginners, as well as professionals, prefer a 4-in-1 welder that offers a combination of MIG/Stick/TIG welding along with plasma cutting facilities. However, 4-in-1 welder models are few in number and most models that you see in the market are 3-in-1 welders. These welders usually offer any of the following combinations of welding processes.
- TIG/MIG/Stick which is ideal for most welding processes
- TIG/MIG/Cutter which is perfect if you want to work with different types of metals and also carry out some construction work
- TIG/Stick/Plasma is a combination that works great for exotic welding.
Once you have decided which combination is ideal for you, making a choice will be much easier.
Welding Type Preference:
A common problem with most multi-process units is that though they offer 3-in-1 or 4-in-1 facilities, all the three or four types of welding processes aren’t equally good. This means that the unit will perform any one of the welding processes to the best of the standards, while the others will have an average outcome. For example, if you think that you would mostly require TIG welding, then buying a welder that offers the best performance with TIG would be your best pick.
The amperage range of your welder will determine the kind of work you can do with it and thus, considering the amperage range of the unit that you plan on buying is vital. For a DIYer willing to work only on simple household repairs and maintenance, amperage of 150 amps should be good enough. However, if you want your welder to do more than that, you will need better amperage. As such, welders with an amperage range of 200 – 300 will be ideal for automobile repairs, pet projects, etc. Better amperage will be required if you want to work at a professional level.
Welders can run on both AC and DC currents. However, a good number of welders usually support only one type of power source – either AC or DC. Moreover, different welding processes require different power sources. For example, if you are planning to weld materials like steel, you will need direct current while AC current is ideal for metals like magnesium or aluminum. As such, it will be ideal that you buy a unit that supports and works efficiently on both AC and DC currents as this will eliminate the problems with the source of power.
Not only is the power source an important point of consideration, but the voltage considerations must also be made. If you have only a 110V power source, then you cannot buy a welder that supports only 220V and vice versa. You either need to buy a welder that can run on dual voltage sources or make sure that the welder you buy supports the voltage that your power socket offers. It must also be remembered 110V welders will offer lower output than their 220V counterparts.
Whether you are a hobbyist or a professional, having a unit that is complex and complicated isn’t an ideal choice. Having to go through a series of steps to get your welder up and running is something that no one will like. Not only that, there are more chances of you going wrong. That is why while choosing the best multi-process welder to make sure that it is easy to set up and use. Units with precise control and digital displays rank first in this regard.
Different models from different manufacturers come loaded with different functional features. Though some features are common with most models, each model will have a number of special features that can be useful to the welder. These additional features usually vary from manufacturer to manufacturer as well as from model to model. However, before you go for a model with added features and facilities, it is important to determine whether you need the features at all. If you are planning to do some very basic welding work, it is quite possible that you will never require those extra features that you are paying for. So, you will be spending money on features that you do not at all need.
The weight of the welder should also be another determining factor in your choice. If a welder is too heavy, it would be difficult for you to move it around for home repair and improvement projects and this may render the welder partly or totally useless. That is why, if you need to shift the welder from one place to another quite frequently, go for a compact model that weighs less. However, if you are going to use it in your workshop and needn’t move it around a lot, this shouldn’t be an issue.
If you are planning on buying a heavy-duty multi-process welder, it may wise to consider the cooling options that you have. Heavy duty units usually generate a lot of heat and would need efficient cooling to ensure that they can run their duty cycle. That is why, you should choose a model that comes equipped with built-in cooling options, or it may add to your expenses.
Price and Budget:
Whether you are planning to buy a multi-process welder for your DIY tasks or professional projects, you must have already prepared a budget for the purchase. Your budget will also determine the kind of welder you will be able to buy. If you have a higher budget for the purchase, you will surely be able to buy the latest models from reputed brands. However, if you have a tight budget, you will have to make do with a basic model that will be able to perform basic welding tasks.
That being said, it is never wise to overspend on a welder. Even if you can buy a higher priced welder, it may be that you do not need one such unit. Ideally, beginners can have a basic welder at around $200 – $300 while DIYers may find welders that fulfill their needs at a price range of about $500 – $800. For industrial grade welding work, you may need to shell out in excess of $1500 for a good multi-function welder.

Steps to Using a Multi-Purpose Welder
If you are just starting out with welding, it is important that you take it slow. Welding isn’t a process that you can learn well in a day and you shouldn’t even try to do so. Be organized and diligent in your preparations and you should do fine with welding. Here, we will lay out a simple, step-by-step guide to get started with using a multi-function welder –
Determine the Welding-type:
You may have a multi-process welder at hand which can work on any type of welding process, but you have to first decide which welding process you would need for the task at hand. This is important and will help you proceed with the next steps.
Create a Welding Kit:
If you have simply bought the welder and not a kit, you will have to make your own welding kit. This should ideally contain a chipper hammer, miter clamps, angle grinder, welding pliers, welding wire, shielding gas, etc. You can also buy a welding cart for added convenience.
Don your Protective Gear:
Once you are ready with your welding kit, you can now put on your protective clothing including jackets, goggles, boots, gloves, etc. This will ensure you can stay protected from heat, debris, gases, sparks, etc. that are generated during the welding process.
Get Everything Ready:
Before you get you welder started, make sure that you have everything ready at hand. Open the windows and doors of your workshop or the place where you want to work so that the fumes can escape easily. Make sure to inspect that the welder and everything associated with it like wires, switches, sockets, etc. are in good condition.
Get the Metals Ready:
You have to also make sure that the metal parts that you want to weld are ready for the process. Make sure that the metal is free of paint and rust as this can inhibit the welding process. You must also make sure that the metal pieces are free of contaminants like debris, dust, and dirt. Keep the metal dry and ready for welding.
Start with the Welding:
The metal parts must be clamped tightly and in place before starting up the welder. Once done, start the machine and slowly move it along the joining lines to start the welding process. Do it slowly so that the first pass that you make is good enough. You can follow up with the repeated passes as necessary.
Safety Precautions for using a Multi-Purpose User
Whether this is your first purchase or you have had welders in your arsenal, it is essential that you maintain certain safety standards while using one. This may seem to be a bit over-the-top for experienced welders, but neglecting safety measures can land you in seriously dangerous situations, not to mention the damage that it will cause to your project. So, every time you use a welder, you need to take the following safety measures:
- Welding is bound to produce gases, most of which are harmful to humans. They may cause short-term and long-term illnesses such as asthma, breathing troubles, etc. These gases are also potential carcinogens, which mean that they can lead to cancer. So, before you start welding make sure that you wear a helmet.
- Welding gases are not the only problem that welders may have to face. Welding can cause burns in case of an accident. That is why, you must always protective wear like gloves, welding jackets, welding shoes, etc. during welding.
- To keep your eyes protected from debris that flies around while welding, wear safety glasses.
- Make sure that any clothing that you wear during welding mustn’t be made of synthetics. This is because synthetic clothing can start melting when subjected to high heat and stick to your skin. It is better to wear cotton, woolen, or leather clothing.
- Never fold the sleeves of your jackets or roll up your pants as the sparks produced during welding may get trapped in these folds.
- It is also essential that you keep the welding area free of flammable objects or any type of obstruction that may prohibit the free movement of the machine.
Multi-process welders are, indeed, your best pick if you want to be versatile in the kind of tasks and projects that you want to work on. Most of these welders come with easy operational modes, which mean that they are good for newbies as well as professionals. These all-in-one welders can work wonders for you, even if you are just starting out with metalworking and need equipment that can get you through all work opportunities that you may come across. However, it must be remembered that, in many a case, these models may excel at any one of the welding processes while leaving more to be desired for the other welding types. Though there is usually a slight compromise in quality in such cases, if you are looking for excellent end results, you may consider buying dedicated end results. But for the majority of metalworkers, multi-process welders work just fine and up to their expectations. So, you can think of investing in the best multi-process welder without any worry.
