These Multi-Process Welders are capable of switching between MIG, TIG, and Stick welding with very minimal adjustments, allowing you to handle a wider array of welding jobs.
This means that no matter what metal you are working with, you will have the welder for it.
These multi-process welders don’t make as much sense for a shop that needs to fabricate 3,000 cattle gates out of steel. However, if you are in a repair environment where you have a wide variety of items to work on, they are an excellent choice.
Note: Don’t forget to buy a welding helmet. Eye damage is a real risk from working unprotected with welders.

The 8 Best Multi-Process Welder Reviews
ESAB Rebel EMP 215ic All-In-One Welder
The frustrating thing about shopping for a multi-process welder is that it is difficult to find one welder that can do it all. You have probably already discovered that there are a few common configurations of DC MIG/TIG and AC TIG/STICK.
But what about a welder that can do both AC and DC current, as well as both MIG and TIG?
This is the rare specimen of a machine that can deliver.
The ESAB offers a sMIG (“smart” MIG), that learns your welding style and adapts the wire feed and arc to match. This speeds up your work and enables you to deliver a more consistent finished product.
Then you get both AC and DC TIG. If you are ready to start “laying dimes,” this one is ready to help. The AC feature is essential if you need to weld aluminum. This one is going to deliver cleaner welds on much thinner aluminum compared to what the other tools on our list can offer.
This one has a lot of fine-tune settings. I love that it has inductance. This is so critical for getting a more consistent arc on poor surfaces. It also has a setting for accurate spot welds. And, if you find a combination of settings that you love, you can use one of 4 preset areas to save it.
It also comes with stick welding capabilities.
I have to admit. It is hard to find a tool that not only offers all of these features, but that also provides them with a best-in-class level of performance.
Your duty cycles are going to vary based on how high of amperage you are using. For example, when laying down 205 amps of MIG, you’ll be limited to a 25% duty cycle. But at 110 amps, you have a 100% duty cycle. That’s a lot of work without a break!
It also has some of the most variations of all of the tools and will let you get down to about 15 amps of power, making this one of the lowest power options for working on extremely thin metals.
If you need one tool that can do it all, the ESAB takes the title. It’s Zachary’s top pick for an all-in-one option.
MILLER MULTIMATIC 220 AC/DC Multi-Process Welder
The Miller brand was one of the first brands that I ever worked with as a teenager. They have been around for years, and I’ve had more than a few friends who trusted their livelihood to the durability and longevity of their tools.
The Multimatic fills a critical hole in the Multi-process industry. This one brings a level of professional-quality performance to an otherwise sparse field.
As with the ESAB above, this is both an AC and DC TIG Welder. If you want to be able to work on pretty much any exotic alloy, this machine is going to rise to the task. It also includes the foot pedal for maximum tig performance. It has full AC balance, and DC Pulse controls for accurate, clean, welds.
But then you also have the robust MIG welding component. If you have ever worked with a Miller wire feed drive before, you know that you have something to look forward to. The cast aluminum drive systems are always extremely reliable and precise. They put them in at an angle so that ti flows without kinks or bird nests.
It also comes with a stick welding setup. That is going to come in handy the first time you have to weld cast iron.
This MultiMatic has the advantage that it can use both 120v and 240v power supply. This dual voltage design comes in quite handy when you are called into work on a project where you need to work off of generator power.
On the high end of the Duty cycle, Miller recommends a 20% duty cycle for MIG welding at 200 amps when you are plugged into a 220v circuit. That is right up there with the ESAB. The advantage of this setup is that you can also limp along with up to 125 amps at 60% duty cycle if you only have 110v circuits.
Now, all of these features come at a price. But if you want one that you can throw in the back of your truck and solve any problem that comes at you, then this is the model you need to get.
Weldpro 200 Amp 3-in-1 Welder
The Weldpro 200 Amp is a strong contender on this list and offers an incredible set of tools.
With this kit, you are getting the MIG kit as well as a DC lift TIG kit. So you are going to be able to use both, opening up more metals for you to work with. One thing that is nice about TIG is that you can braze different metals together with it.
You also get all of the welding equipment that you need. From a gas hose to the ground clamp, it comes with all of the tools that you need.
Lincoln Electric MIG 210 MP Multi-Process Welder (K4195-2)
Lincoln has been a long-time leader in the fabrication industry, and this MIG 201 MP leads our list as an excellent choice.
If you want a multi-process welder that does not compromise on quality, this is a top contender.
With this kit, you are going to get a MIG, DC TIG, and stick welder. It also comes with the Magnum PRO 100SG Spool Gun for welding aluminum. This is a pretty costly upgrade if you choose to add it later, so it is nice to see it included.
The one thing this welder is missing is the ability to weld aluminum with TIG. For that, you would need an alternating current option. However, you still have the TIG for those super-thin repair jobs where you don’t want to burn a hole or overheat the project.
One of the best things about this setup is how easy it is to adjust the settings. The three knobs control a digital display, and the entire thing is extremely straightforward and easy for even a beginner to get it dialed in on the first try.
This is a well-built machine. The heavy gauge metal exterior will protect it as you take it from job to job. At 40 pounds, it is quite portable.
The drive system for the GMAW wire is designed to keep “bird nests” from occurring. Overall, it is designed to be an equally rugged and yet intuitive machine.
Everlast PowerMTS 251Si Multi-Process Welder
Everlast has some of the best pricing on its professional-level equipment. The POWERMTS 251SI is one of those models that I get questions about. As a 110v/220v dual voltage option, it gets a lot of interest among professionals and entry-level users alike.
What jumps out about the Everlast is their choice to go with a high-end IGBT inverter, with added control for digital waveforms. This means that the Everlast controls the arc more closely than probably any of the other machines on our list.
If you are one of those perfectionists who feel like they can never get the perfect bead, the digital controller on this one is going to get you most of the way there.
This is the only machine on our list that offers both pulse MIG and pulse TIG welding. These pulse welding options are handy when welding upside down. They also dramatically control the shape and penetration of the weld.
As with most of the options on this list, this one does not handle AC welding. So, for your aluminum work, you will either want to use Flux Core and get a spool gun.
For the TIG, you can switch between high-frequency contactless start, or go with the lift start option.
You’ll need to get your consumables and the tungsten rods, but everything else is included. If being able to create the prettiest welding beads in town is important to you than this is the choice to go with.
Forney 324 MIG/Stick/TIG 3-in-one 190-Amp Weld
What I love about this welder is how much power it offers. With a 190 amp rating, this one is ready to handle some of the toughest jobs.
With this kit, the focus is on the MIG welder. It comes with the MIG gun and has an all-aluminum wire feed drive. The geared idler and drive spool do a good job getting a consistent feed on the wire.
It also comes with a stick welder. Having a stick welder is extremely handy for those weird tasks that you run into, such as welding cast iron.
Now, this welder also has the ability to be a TIG Welder. However, you need to invest in a TIG torch and a foot pedal which are sold separately.
Also, if you want to do aluminum work, you’ll probably want to get a spool gun, which is another separate charge. It is a spool gun compatible. You just have to buy the tools separately.
This one also offers the synergic MIG burn, which is a pulsing arc that separates the beads. Basically, it is like pulsed welding, but it matches the pulses to the wire feed speed to ensure that you get even droplets and a better finish.
As one of the American-based companies on this list, Forney brings its 80-year track record to the industry, leading the way with its consistent performance and affordable products. They also have an extremely responsive customer service team.
This one occupies an odd space in the market between the super-cheap Lotos and PrimeWeld models that tend to come with all of the needed guns and hoses and the high-quality Hobart, Millers, and Lincolns.
However, it has a pretty wide fan base, and any problems are just a phone call away from getting resolved.
PrimeWeld Ct520d Welder and Plasma Cutter
Up until this point, we’ve been looking at a lot of machines that offer MIG/TIG/Stick Combinations.
I wanted to add an option that offered a plasma cutter as well.
You are likely familiar with plasma cutting already. It uses an ionized arc of electricity to cut through steel. It’s about twice as fast as using a cutting torch, making it a favorite of fabrication shops and hobbyists alike.
It comes with a 50 amp plasma cutter. That’s more than enough to cut through 1/2-inch thick metal.
You’ll still need your own compressor to connect it to for the plasma side, but otherwise, it comes with the cutting torch and everything else you need.
Then, it offers a DC Tig Welder. These are great for working on thin metals up to metals of about 1/4-inch thick. You’ll find that this system is going to work best on mild steel and stainless steel. TIG systems lay down some of the most beautiful welds, and this little box is no different.
You’ll probably want to go ahead and buy the added foot pedal if you plan on doing a lot of TIG work.
And then it also comes with an MMA or stick welder.
The only area where this little tool is going to struggle is with aluminum welding work. If you have clean, thick, aluminum, you can make it happen with this machine. But it’s likely going to burn through thinner alloys.
However, as a multipurpose cutting and welding tool, it is a pretty good choice. It has a 60% duty cycle even when running at the highest setting, to the risk of overheating are extremely low.
One of the biggest selling points of this kit is that it comes with both a three-year warranty. Most of my readers are home hobbyists who only use
This is one of the most-popular multi-process machines and is one that is very common in the small shop. As with the PrimeWeld model above, you are getting a plasma cutter that can go from 10 amps to 50 amps.
It does have a pilot arc torch, which is a nice feature that means it can initialize the cut without the tip touching the metal. Not only can this be easier to use, but it also helps protect the tips and reduces the number of consumables you go through.
Then, you get the TIG welder function. This one also has the high-frequency start where it can arc by itself and doesn’t require you to do a scratch start to get it going. One of the top things with this one is the IGBT inverter technology. Now, most of these use inverter technology, but Lotos tends to have a slightly better system for the price and includes pulse width modulation.
All of this means that you get that “bacon sizzle” crackle and a perfect bead.
As with the model above, this is a DC TIG setup. You need to buy an Argon regulator and hose kit to connect it to the machine, but it comes with the Stick Leads, Tig Torch, and Plasma Torch.
The connection for the air compressor for the cutting side of the tool should work with any 1/4-inch quick connection for a compressor.
As with most of these tools, it can handle both 110 and 220 voltage inputs. However, it is going to perform best at 220 volts.
Most of these welding machines have one or two systems that they expect you to use as the primary welding process. Typically, that is going to be either the MIG or the TIG function. Then, Stick welding is added as an easy addition.
The outlier to this rule is the Miller Multi Matics and the ESAB Rebel. Both of these are equally capable with either GMAW or SMAW.
The lightest option is about 40 pounds, while the heaviest is under 60. None of these units are highly portable, but you are going to be able to move them around with the attached handles or get a cart to wheel them around on.
If portability is your most important concern, you will want to get a machine with a single focus.
Flexibility is the name of the game. All welders work best with a 220v power source, but it can be handy to have a welder that can get buy on a 100v circuit.
Most of the models available are dual voltage systems that let you do smaller jobs with thinner metals on a lower voltage power supply.
If you are doing a lot of production work, you are going to need a high-end brand that is rated for the long hours and intense pace of professional work.
Many of the lesser brands that are imported are excellent for weekly use in the DIY garage. However, they don’t tend to last under years and years of daily use.
Additionally, a better quality welder will typically deliver more consistency in its performance over the years of use.
