Does your shop or garage need more than one welder? Your need a MIG welder for thin shits but you also need a tig welder for stainless still? and it would be neet to also have a Stick welder for outside’s dirty work… 

You can buy the separate welding machines, but to save space and maybe money the best choice would probably be one of those multi-process welders.  

Now multi-process welders are all expensive (less or more) but Not all of them are bang for your buck.  So to not trow your (probably hard earn money) take a look at these reviews of the best multi process welders and specifications carefully and chose a welder that will suit your needs. 

Just a quick shout out guys! Rest assured that I put these products on the list due to their quality and my personal opinion as let’s say, experienced welder (burn marks, ruined eyesight, and all).

I just want to be transparent with you and inform you that my site Weldingpros.net may obtain a share of sales or other monetary compensation from the links on this page.

So, buddy, I hope that using this article you pick a great welder and put some nice bits on that metal (and if not just grind it a little ;)).

The Best Multi-Process Welders: Reviews

  • The Everlast PowerMTS 251Si Pulse Multi Process Welder
  • The Lincoln Electric POWER-MIG 210 MP Multi Process Welder
  • The Miller Electric Multimatic 220 Multi Process Welder
  • The ESAB EMP2151C Multi Process Welder
  • The Lotos LTPDC2000D Non-Touch Pilot Multi Process Welder
  • The Forney MIG/Stick/TIG 3-in-1 190 Amp Multi Process Welder
  • The Weldpro 200 Amp Inverter

1. 2019 The Everlast PowerMTS 251Si MIG TIG and Stick 250amp 110V/220V [Top Pick]

This fourth-generation Everlast multi-process welder is a great all-rounder and my top pick. It’s a solid improvement over its predecessor and the stick welding function is far more adjustable than on the old model It was also strikingly easy to use.

The hot stick start option makes it easy to burn 6010 and even 7018 rods and it has a very familiar set up.  If you’re used to MIG welding, in particular, you should be up and running with the Everlast in no time at all. The price tag is also very user-friendly.

I find it to be the best of multi process welder simply because it offers so much for a reasonable price while at the same time offering the great quality of build and the durability. The only important thing that it does not offer is the ability to AC TIG weld but if that is not a deal-breaker for you then you should seriously consider this welder.

The fact that it provides you with the HF TIG start and lift arc start makes it stand out a lot among the multi-process welders and especially at this price range.

It also comes with everything you need unlike most other multi process machines which will save you money. Most multiprocess welders at this price range will just give you a MIG and Stick welding equipment but Everlast offers both the TIG torch and the TIG foot pedal which can cost quite a lot if purchased additionaly.

2. The Lincoln Electric POWER-MIG 210 MP Multi-Process Welder

The secund welder in our test was the Lincoln’s multi process welder. It was one of the best-built machines in our test and I feel confident that it’s going to last more then a few years of heavy use.

If you watch “Forged in Fire” on the TV then this is the machine they choose to use for their welding. I’d also note that it’s one of the most popular welding choices on Amazon and it currently has no bad reviews, whatsoever.  Probably the best welder if you are a beginner and want to build your welding experience, considering how easy is to set up welding parameters on his color display.

When talking about brands like Lincoln Electric it is easy to expect durability, efficiency, great welding experience and ease of use. The Lincoln 210 is all of those and more but it does have its flaws. It doesn’t offer the ability to AC TIG weld and it doesn’t come with the TIG torch or the foot control. One thing that I find most troubling is the TIG touch start. This is the most simple and basic TIG start method. I expected at least the lift start.

Aside from the issues above the Lincoln electric powermig is a very very good welder that will serve you for a long time. It is durable and almost no one in the industry was dissapointed by it. This is one of those machines that will mark a certain peroid when it comes to the overall quality of the build and ease of use. If you are reading this article as a newbie chances are that you have already heard of this welder before which speaks for itself. If you want to learn more about this welder check this post.

  • The Magnum PRO 100SG Spool Gun comes as part of the pack
  • It’s a really well made multi-purpose welder

Cons

  • The user manual wasn’t easy to follow
  • You don’t get an AC output (no TIG welding aluminum)
  • The touch to start TIG technology
  • There’s no tungsten electrode or foot pedal in the box, you have to buy them

3. The Miller Electric Multimatic 220

The best machine in our tests for this review, by far, was the Miller Electric Multimatic 2020. It supports all 4 types of welding but it wasn’t our number one choice. Why? Because of the equally impressive price tag.

You’re only going to splurge on this if you’re going to make regular use of all the functionality but if you are then it’s a no-brainer. It’s exquisitely well made and will make welding easier for everyone in your workshop.

Miller is a brand that doesn’t mess around. Period. And this welder is probably one of the most shining examples of their consumer line that is dedicated to the smaller shops and single welders. They make serious industrial welders but they are also heavily focused on creating the quality machines for everyday use by welders in their shops.

Multimatic 220 is the best multi-process machine there is in my opinion. This multi-process machine can do pretty much everything and comes with everything. Meaning that yes it can AC TIG weld and comes with all of the TIG equipment. It’s also a MIG and Stick machine and of course there and their equipment is included as expected.

The best thing about this welder is the QuickTech™ technology by Miller. This allows you to switch between the processes in a blink of an eye. The way it works is that you can have both the MIG and TIG torch attached at the same time and two different gasses for each process.

You can have two different settings active at the same time and all that you have to do is either pull the trigger on the MIG torch or press the foot control and it will immediately switch to the process you started to use while recalling the last used settings without forgetting the settings of the other setup process so that you can easily switch back. No other welder offers this much ease of use.

One thing that I do not like is that this welder has low duty cycle at high amps. MIG and TIG will give you 20% duty cycle at 200 and 210amps while the stick at 200amps will be just 15% which is not good enough considering the kind of work this expensive and overall awesome machine is meant for.

MILLER ELECTRIC MULTIMATIC 220 AC/DC #907757
  • Multiprocess capabilities allow for MIG, flux-cored, AC/DC TIG and stick welding. The Multimatic 220 AC/DC comes equipped with all accessories to weld any process, unlike other machines where you need...
  • Auto-Set Elite can be used on multiple materials and multiple processes with the ability to fine tune your settings. Easy to set up and use.
  • Pro-Set (TIG and stick manual modes) - eliminates the guesswork when setting weld parameters. Simply adjust control until Pro-Set appears on the display and the number turns blue.
  • Intuitive color LCD user interface makes it quick and easy to adjust parameters.

  • You can use shielding gases for both MIG and TIG simultaneously
  • Super customizable and the auto-settings work well for high skill level welders

Cons

  • Cost – this much functionality in one box is expensive

4. ESAB Rebel EMP 205ic AC/DC Multi-Process MIG/STICK/TIG Welder

It was hard to chose which is better between this ESAB Rebel 205ic and the Miller multimatic. ESAB 205ic is a beast of a machine which can weld all four processes just as the Miller one above. AC TIG, DC TIG, Stick and of course MIG. 

ESAB is also one of the best brands there are in the welding industry and among their multiprocess line, this one seems to be the best they offer.

This welder offers a lot of features and settings to make your work easier and better. High-frequency TIG start, the balance, frequency and pulse adjustments for TIG. Both AC and DC TIG meaning that you can TIG weld aluminum. Welds are high quality and using the settings you can achieve varying welds by penetration or width.

Besides a regular MIG setting, you can choose the smart MIG setting which helps by adapting the arc for more quality and repeatable welds.

There are also settings for stick welding like hot start and arc force which help keep the arc going even in situations when you apply force and try to burry the rod in the joint. This is useful for professional welders like pipeline welders. This welder will also stick weld using the 6010 electrodes without any issues and there is a setting for it. Not a lot of multiprocess welders can handle the 6010.

Like the Multimatic 220 from Miller, this is a machine for people that will use it for serious work. It is costly but it justifies its price range.

Our one word of caution is that they don’t seem to have a perfect reputation for customer service and that when things work, they work well but if they don’t, it might take quite a bit of effort to get things fixed under the warranty.

ESAB Rebel EMP 205ic AC/DC Multi-Process MIG/STICK/TIG Welder
  • True All-Process - excellent performance on MIG, Flux-Cored, STICK (including 6010 electrodes), DC TIG and AC TIG industrial applications
  • Professional TIG features such as High Frequency start in DC and AC modes, balance adjustment, frequency adjustment and Pulse DC.
  • sMIG Technology - exclusive sMIG ("smart MIG") feature continuously learns and adapts to the operator’s welding technique to provide a stable arc and superior, repeatable welds; increases...
  • Unmatched Portability and Durability weighing in at only 49 lbs. (22 kg), Rebel EMP 205ic AC/DC with 5 handle roll cage can tackle any job around the shop or out at the job site

5. The Lotos LTPDC2000D Non-Touch Pilot Arc Plasma Cutter TIG Welder And Stick Welder 3-in-1

If you want to save money, this is the best welder of them all but it’s also not fit for professional use. It’s meant for the home user learning to weld or to get some DIY project done.

In general, you’ll pick this if plasma cutting is important to you and occasionally you need a TIG welder because this is a great TIG plasma combo.

The plasma cutter feature is pretty good with a very high duty cycle. You can run it at its maximum of 50 amps at 60%. Keep in mind thou the plasma cutter’s consumables are not standard and can only be purchased from the Lotos.

6. The Forney 324 MIG/Stick/TIG 3-in-1 190 Amp Welder 120V/130V

This low-cost option is great value for money if you’re looking for an all-purpose but light use welding machine. If you’re looking for heavy-duty use, look elsewhere, the 20% duty cycle at 170 amps is going to seriously hamper your productivity.

I also like to see them include more accessories as standard though we appreciate that leaving them out makes the initial purchase price more attractive to potential buyers.

Considering the price range this is quite a good machine for hobbyist welders and if you don’t need the TIG welding at first then you will not mind that the TIG torch is not included. This machine is also capable of the TIG L.F. which is great considering that this is a machine for light welding jobs.

The synergic feature is very helpful for beginner welders because it will optimise the arc automatically to produce better welds and reduce spatter. And if you dont need this kind of automatic settings you can easily switch to manual settings.

Forney 324 MIG/Stick/TIG 3-in-one 190-Amp Welder, 120/230-Volt, Green
  • MULTI-PROCESS WELDER- 3 in 1 Stick Welder, MIG Welder and TIG Welder (Accessories for TIG Welding not included) everything you need in one machine
  • EASY TO USE- Easy start makes every strike EASY! Three position switch allows you to change process quickly
  • CONTROL YOUR WELD- Move at the right speed that fits your need, the flow meter supplies a correct regulation of gas using a single stage piston

7. The Weldpro 200 Amp Inverter Multi-Process Welder With 220V/110V MIG/TIG/Arc

It’s clear when you take it out of the box as to why this is a low-priced model – it’s just not as well built as the other welding machines that we tested. However, if you’re just looking for something for 2-3 years use, this might be a good option.

It’s very light and easy for a single person to haul around if it’s needed. The leads are a really good length too. If you’re on a very tight budget, The Weldpro might be what you need.

I like that it comes with all of the needed accessories MIG torch, TIG gun, Stick holder, ground clamp and etc. If you are looking for something cheap for light use and simple welding projects than this welder will provide you with needed accessories to work right away using all 3 processes. It also supports lift arc TIG start which is good and its duty cycle for all three setap processes are pretty good even at high amps like 200 amps of 30%.

Things To Think About When Selecting Your Welder

The Materials You Will Use

The materials that you intend to use are going to have a real impact on the multiprocess welder that you opt for. You need to think about the metals you’re working with and the sections of gauge you intend to weld.

You’ll find that as long as you buy a decent quality multiprocess welder that you’re going to have few problems with stainless or regular steel welding projects. But if you’re welding aluminum, you need to think a bit harder about your purchase.

TIG welding aluminum means you need an AC function on the TIG machine or multiprocess welder. Ordinary machines only have a DC output and this is no use for aluminum. You may also want a TIG pulse function because it can aid in the process of welding aluminum.

You also might want to look at the amp range for the welder as you need a broad range if you’re going to weld heavy materials together and if you’re only going to weld light materials, you can skip this capability and go with a narrower range.

The Main Function Of The Welder

While you may be buying a multi process welder, you’re going to end up using it mostly for a single welding process with some other stuff coming up every now and again.

It’s best to pick your multi process welder to excel at the primary welding process if you can.

However, if you really are going to be dipping in and out of all 4 welding processes then you might find that the MILLER ELECTRIC MULTIMATIC 220 is one of the best multi-process welders for you.

That’s because it’s great at handling all the welding types and has a broader range of features than most other machines. If budget is an issue, the next best choice might be the Everlast Power MTS 251Si.

The Quality Of The Welder

You get what you pay for and there’s no escaping the fact that the more you spend on the quality of a multi process welder with greater power capabilities, the longer it will last.

In general, it’s easy to tell what the best multi-process welders machines are – they have a long warranty period. Though, you want to scope out the fine print to make sure there are no hidden clauses (there are often exclusions for torches, leads, etc. which have much shorter warranties).

Tip:
Multi Process welders with long warranties cost more, to begin with, but over time, they’re going to save you a fortune. You won’t be constantly repairing or replacing it and that means it’s going to be productive for longer. It means no repair costs and less downtime.

We’d also recommend sticking with a respected and well-known brand, this gives you confidence that they’ll be around for long enough to honor the warranty. Miller, ESAB, Lincoln, Everlast, etc. are good choices.

The Challenges Of Using Multi-Process Welders

A multi-process welding machine has lots of advantages but we won’t pretend that they don’t have a few drawbacks, either.

Firstly, you may find that your multi-process welding machine doesn’t offer an AC TIG welding mode. It’s not always an issue (most welders don’t weld fine aluminum) but if you need it – then it’s an issue. You want to be careful to ensure that your chosen welder is capable of handling the welding process you need it to.

There is also some changeover time required when you move a multi-process welding machine from one task to another.

That means changing welding equipment like shielding gas, unplugging or plugging in other tools, etc. If you’d bought 3 different welding machines, this might not be needed.

However, if you want to avoid changeover issues you can just buy a better (more expensive) multi-process welding machine such as the Miller Multimatic 220. Though, we appreciate not every workshop will have the budget for it.

The other potential disadvantage is that if you’re relying on one machine to do all the work – if it breaks, all your work stops. So, it can be handy to invest in a backup if you can afford to.

The Benefits Of Using Multi-Process Welders

There are also some obvious benefits of using multi-process welders and these include: you can tackle more jobs than you might have been able to otherwise within your workshop or onsite.

That can increase your profits and buying one machine rather than many machines can also save you money.

So, the big advantages are versatility (do many jobs), convenience (one welding machine rather than many), space-saving (one welding machine) and cost (at least, in most cases).

When you see an expensive multi process welder, it’s a good idea to remember how much more it would cost to buy all the machines separately, then it will feel like a bargain.

Frequently Asked Questions (FAQs)

What Is A Multi-Process Welder?

A multi-process welder is a welding machine that handles up to 4 different welding processes.

Such a welding machine saves you from having to buy multiple machines and also makes it easier for a workshop to handle many different jobs at once. It can also free up space in a cramped workshop.

Are Multi-Purpose Welders Any Good?

Much depends on the multi process welders that you buy. Whilst none of them are likely to be as good as a one welding single-purpose machine of the highest quality, most multi-process welders are perfectly capable of getting the job done.

You may find, however, that some mid-range multi-process welders require a bit more effort when switching between jobs than you would need to put in if you had several single process welders.

Conclusion

The best welding machine in our tests was the Miller Electric Multimatic 220 model. However, we felt that it was also beyond the budget range of most small workshops.

So, our top pick multiprocess welder is the Everlast Power MTS 251Si which neatly balances capability with a sensible price tag.

However, if you’re just getting started with welding and don’t need the best multi process welders you might also consider the Lotos LTPDC2000D which is by far the most budget-friendly model in our review.
