Multiprocess welders come in all shapes, sizes, and combinations of the various types of welding. As such their quality varies a lot depending on what you need them for, and it’s difficult to find which ones are truly worth your time without sifting through a ton of chaff. This list is designed to help narrow down that search to a number of options that fit best in various niches.
In a Rush? Here is Our Top Choice
Everlast PowerPro 164
Best Multi-Process Welders On The Market 
Top 7 Multi-Process Welders - Reviews
1. Everlast PowerPro 164 - Top Pick
The main mark against the Power pro is the process. While expensive, it is a powerful machine, capable of high duty work as all of a TIG welder, stick welder, and plasma cutter. It easily changes between the welders and plasma cutter, making it perfect for jobs that require constant switching between both, and can do both AC and DC TIG and stick welding, making it great for both spot and extensive welding jobs.
The AC TIG welds a 3/16” swathe, the DC TIG 3/8”, and plasma cutter a 5/8” cut, making it good for larger jobs.
While described as portable, that’s not entirely accurate. It weighs 60 lbs, making it movable but bulky and not suited to constantly shifting around or carrying by hand long distances with other equipment. It’s just movable enough to make it perfect for around a shop or job site, but not so much if a trek is required to reach your destination with it.
Still, that’s a small mark against it. It works perfectly as an all in one welder that can tackle pretty much any job.
2. AHP AlphaTIG 200X
While primarily billed as a TIG welder, by all accounts it makes for an excellent stick welder, better even than many dedicated stick welders do the job.
As an all around machine few come close to the Alpha 200x for the price. It’s compatible with most outlets as a dual voltage 110 and 220 volt unit and works with both AC and DC current, making it great for both low and high power jobs. It works well with most common materials (steel and stainless steel, plus aluminum) and allows precise welding of thinner gauge materials.
With a single pass it cuts a ¼” swathe through aluminum and ¾” through mild steel (mileage may vary on higher quality steel, but you generally shouldn’t need to weld the higher grade stuff), making it about the average for cutting power.
The only real complaint to be had is the lack of portability. At 69 lbs and around 2 feet on each side, it’s a fairly bulky and heavy unit, but its power and versatility make up for that.
3. Lincoln Electric POWER MIG 210 MP
Marketed for the “welding novice”, this Lincoln Electric multiprocess welder is a good example of the baseline a multiprocess welder should be capable of. It does primarily MIG welding, with the ability to adapt for TIG, stick, and flux core welding. It works with almost any power outlet, being a dual voltage 120 or 230 volt machine, and touts easy setup and change of settings.
The biggest mark against it is that besides the MIG gun, you’ll need to buy attachments for the other functions, making it in practice a bit more expensive than its list price, but otherwise it is a great machine for what it’s trying to be, and allows a new welder to “work up” to different types of welding with repeated small purchases instead of one huge lump sum. Even if it does end up with a somewhat larger pricetag than an all in one unit would normally command because of that.
While not my first pick, it is a great option, particularly if found on sale.
4. Everlast PowerMIG 200
While a hybrid MIG/stick machine isn’t my first choice it’s ideal for certain jobs. If you never find yourself needing a TIG welder for whatever reason, it might be overkill to shell out for a multiprocess with that kind of functionality.
In that case, the Everstart PowerMIG is a good buy for the price, being on the cheaper end of multiprocess units and working well as both a MIG and stick welder. It does steel and aluminum with ease, and can weld up to a 7/16” swathe in the MIG mode on the full 240 volt, 200 amp power draw.
Additionally, it is fairly compact for a multiprocess welder, being around a foot and a half in length and height, and a third of that in width. Combined with its fairly lightweight 35 lbs and it’s quite portable to various job sites or just hauling around your yard or garage by hand.
As an added bonus, it can quickly change over to different styles of MIG guns, making it more versatile than first meets the eye.
5. Amico TIG-200DC
This is primarily a TIG welder with the ability to shift to stick for certain jobs. For what it is it works great, and its only drawback is that like all TIG welders it doesn’t do aluminum. As a dual voltage 115 and 230 volt (up to 200 amps) machine it works with most outlets, as you can expect from most multiprocess welders. It can weld up to a ½” on compatible materials, putting it ahead of the curve from most of the other units in this price range.
Its biggest draw is the small size. It weighs in at only 25 lbs and about the size of a standard toolbox, making it the most portable multiprocess at this level of quality. That alone recommends it as a solid option for most people want to use the device around their home or for smaller jobs on a site, and unlike most portable welders it scales well as a powerful TIG welding option.
6. Everlast SuperUltra 206si
The Everstart Super Ultra is not a primary welder in many senses. It only does TIG welding, and only DC TIG welding specifically. This makes it perfect for precise repairs and spot welding but not much else. It doubles as a powerful, efficient plasma cutter, making it an interesting pairing for a multiprocess machine.
It cuts a ½” swathe on DC TIG and ¾” as a plasma cutter, making it great for handling larger jobs quickly in its specific niche.
The Super Ultra is not recommended as your only welding machine, but as a supplement to a MIG/TIG plus stick machine it works perfectly. The only part that makes that an iffy option is the price. You tend to pay a premium for plasma cutter functions, and this is no exception. It’s nearly as expensive as the top option but less versatile.
Only recommended if you really need an excellent DC TIG machine and have everything else covered already.
7. Weldpro 200 Amp
The Weld Pro does just about everything, for a very low price. It is a dual voltage 110 and 220 volt machine (200 amp maximum) that does MIG (flux core), TIG, and stick welding.
It has easy to adjust and simple to read digital outputs that make maintaining your same amperage for repeat welds easy to do. The only real issue is its energy efficiency is quite low, with only a 30% duty cycle (the standard at max output is 60%).
For what it is that might be an acceptable loss. As a compact, portable package (30 lbs, about a foot and a half on either side) it is one of the only true all in one welders, and is a great price. As a backup portable welder it’s perfect, though it may be wise to avoid using it for truly heavy duty jobs, reserving that for a larger, more powerful machine.
It has been described as a “small, but capable welder” and that description fits its specifications perfectly.
Our Top Choice
Everlast PowerPro 164
The two standout options here are the Everstart Super Ultra and AlphaTIG 200x. Both offer a lot of versatility in different arenas. The others serve more specific purposes, being less good all rounders in comparison to those two top choices, and are largely interchangeable in raw quality besides their specifically filled niches. Depending on what you need any of those could be completely wrong for your purposes, either being redundant with a larger machine you may already own or limited to smaller jobs when you may need something more powerful. Just keep that in mind when browsing the list and they should all work great if chosen properly.
